1. This certificate describes the use of exhaustion appropriation accessories and provides admonition on safeguards to be active adjoin accessible hazards aback planning and accustomed out assignment activities involving the use of exhaustion appropriation equipment. This admonition was ahead included in HSE Operational Circular OC 234/9 “Vacuum Appropriation Attachments“ and OC 234/12 “Vacuum Appropriation Tubes” and their associated admonition documents.
2. This admonition is advised acceptable convenance but it is not compulsatory and may not be applicative in all circumstances. You may about acquisition it advantageous in chief what is adapted to accede with the law to abate the accident of abrasion to operators and added bodies and to abstain accident to bulb and accessories etc.
3. Exhaustion appropriation accessories is broadly acclimated in abounding automated sectors for the appropriation and administration of materials/components that accept a collapsed or bland surface. In accurate abstracts such as metal or bottle plates, accurate slabs, pipes, adhesive boards, artificial laminates, adhesive bags, beer kegs and tins etc. can be calmly aerial and handled appliance exhaustion appropriation equipment. Exhaustion appropriation accessories utilises assimilation pads (in abode of accepted appropriation accessories) for the purpose of adhering and appropriation loads.
4. This admonition covers 2 basal types of exhaustion appropriation equipment:
The aberration amid a VLT and a VLA is that VLT is acclimated for both arresting and appropriation the load, but a VLA functions as an adapter for arresting the load.
5. A Exhaustion Appropriation Tube is a appropriation apparatus that comprises of:
6. Manufacturers/suppliers of this accessories commonly accumulation it on the base of pre-supply tests agitated out on the absolute endless and packaging to be lifted. Appraisal of the accurate blueprint of the boutique attic breadth into which the accessories is installed is commonly included. It is appropriately important that assignment holders should not change the use of their VLT accessories to added articles afterwards above-mentioned appointment with the suppliers of the equipment.
7. A exhaustion appropriation tube utilises the conception of a exhaustion via the assimilation pads to attach itself to the article actuality lifted. An electric-powered assimilation pump is acclimated to actualize the exhaustion acceptance the assimilation pads to allowance anon assimilate the article actuality lifted. The cantankerous exclusive breadth of the appropriation tube is anchored at about bisected that of the absolute cantankerous exclusive breadth of the assimilation pad(s). It is acceptable however, that this bulk could alter hardly amid altered manufacturers of this equipment.
8. This breadth adjustment ensures that at the burning acceptable exhaustion is activated to the lift tube to lift the load; the arresting force via the assimilation pad accessories is appropriately alert that of the load, appropriately abbreviation the likelihood of the bulk acceptable alone and falling.
9. The exhaustion aural the adjustment can be assorted appliance a duke operated ascendancy valve, thereby authoritative it accessible to accession and lower the bulk in a controlled manner. The ascendancy valve is adapted with a handle which enables the bulk to be positioned with a minimum bulk of effort.
10. The adapter of the appropriation tube to the appropriation gantry usually comprises a rotary exhaustion allowance which enables the tube/load to hinge through 360o. This allowance is assurance analytical and should be inspected at intervals bent by a acceptable accident appraisal procedure.
11. The accomplished appropriation adjustment is barnacle aloft the exhaustion pump for its safe operation. In the accident of pump failure, VLT absorb a one way valve amid in the top of the appropriation tube that automatically closes thereby advancement the exhaustion in the appropriation tube. Should the exhaustion abate to an agnate force that is beneath than the force exerted by the load, again the bulk will be automatically lowered
12. The corrugated appropriation tube is subjected to compression at every appropriation operation appropriately its alternative is acutely important.
13. The appropriation tube is a assurance analytical basal which about comprises of a wire able rubberised t tube. This tube is subjected to a abrogating burden (vacuum) and has a cardinal of accessible abortion modes which should be addressed during the architecture and alternative stage:
14. It is recommended that a absolute analysis and aliment adjustment be implemented which pays accurate absorption to all assurance analytical components.
15. Automated accident to the appropriation tube t consistent in absolution of the load.
16. The appropriation of the endless is accomplished by the adapter of the assimilation pads to one or added faces of the load. The user charge ensure that the packaging surrounding (carrying) the bulk is able for the bulk it is subjected to (not apathy the base of the packaging).
17. A exhaustion appropriation adapter additionally utilises the conception of a exhaustion via the assimilation pads for adhering itself to the bulk actuality lifted. It can be a distinct assimilation pad as able-bodied as assorted assimilation pads. The adapter incorporates a cardinal of assimilation pads that fit anon assimilate the apparent of the bulk appropriately enabling a exhaustion to be created amid the assimilation pads and the load. The assimilation pads are an basal allotment of the appropriation attachment. Breadth an electric-powered assimilation pump is used, it can be an absolute assemblage that is affiliated to the appropriation adapter by brim or for non-fixed exhaustion lifters basal with the adapter basal a complete advertisement appropriation accessory. The appropriation adapter is about abeyant from appropriation accessories (e.g. hoist/crane/excavator) and can be absorbed by agency of a angle arrangement, accessories or added automated means. The exhaustion adapter can additionally be an basal allotment of the appropriation equipment.
There are 4 basal types, of Exhaustion Appropriation Attachments: (reference: EN 13155)
18. This adjustment of appropriation is based on the simple ‘suction pad’ principle, breadth an astern alveolate allotment of elastic is pushed assimilate a acceptable surface, expelling the air from beneath the cup. Atmospheric burden on the base of the apparent will again authority the cup in abode adjoin a ample vertical load. The exhaustion can be burst by acceptance air to admission the abandoned aggregate beneath the cup. In the simplest form, the elastic cup with its handle and absolution valve can authority endless of up to about 35 kilograms. These are usually chiral administration accessories and are not aural the ambit of EN 13155
19. Self-induced exhaustion systems can be acclimated for greater endless breadth the elastic cup is replaced by a metal with a adjustable allowance about its accessible end. Aloft the allowance and aural this is a piston, the top apparent of which carries a arena for adhering to a crane hook. On blurred this accent on to the apparent of a bulk to be lifted, its own weight depresses the allowance and the bottomward movement of the agent expels the air from the cylinder. On lifting, the agent is pulled upwards breeding a exhaustion aural the amplitude formed amid the with allowance and the apparent actuality lifted. For endless with a ample apparent area, several assimilation cylinders may be used. Both distinct and assorted accessories may accept abounding refinements. A valve can be adapted to acquiesce easier escape of air on the bottomward achievement of the piston, whilst accession valve can accredit air to admission the abandoned aggregate aback appropriation has been completed so that the adapter can be removed easily. Both these valves can be operated either manually or automatically. Some accessories accept an air-operated admonishing blare which sounds if the bulk is too heavy. They should additionally accept indicators to acquaint of accident of exhaustion etc (ref: EN 13155).
20. Power-operated exhaustion appropriation accessories can booty abounding forms. The ability source, which may be an electric motor or an centralized agitation engine, drives a exhaustion pump which evacuates a backlog catchbasin adapted with a exhaustion gauge. This backlog is affiliated to a assimilation pad or alternation of pads, which are agnate to the cups referred to above. A ascendancy valve is amid in the exhaustion band amid the backlog and the appropriation pad or pads. For best ability the ability backpack is amid as aing as accessible to the appropriation pads which are commonly army on a metal frame. This anatomy can be formed of box sections appropriately closed and utilised as a reservoir. Greater adaptability in use can be alien by applicative anniversary pad with its own ascendancy valve. This enables the abettor to baddest the adapted cardinal of pads for any accurate admeasurement of lift. The ascendancy valves are abiding so that the exhaustion in the backlog catchbasin is activated amid the pads and the bulk while lifting, while air is afterwards accepted to the aback of the pads to absolution the load.
21. Some powered accessories are congenital as independent units for adapter to the angle of a crane, while added abiding installations absorb them into a crane which may be either cab or attic operated. The complete attachment, including ability pack, may be chip with a activity apparatus or breeze band with its controls basal allotment of the capital ascendancy console.
22. There are some exhaustion appropriation accessories of the powered blazon which admission their exhaustion by the use of either a venturi operating from an air line, or from a exhaustion blower agnate in assumption to the calm exhaustion cleaner. The use of this blazon of accessories should be belted to low weight and low acme appropriation applications due to the adversity of accumulation the assurance accessories discussed in paras 25-28. There are added agency of accouterment advancement in the accident of ability abortion such as a assets burden barge for venturi and a flywheel accumulation for turbines. See EN 13155
23. It is recommended that exhaustion appropriation accessories should be dynamically activated in situ as a complete assemblage on the apparent of the actual which they are acclimated to lift. The analysis should be agitated out at the SWL of the accumulation and should simulate the best acceleration/deceleration armament acceptable to be met in the accurate application.
24. As a accepted aphorism the bulk declared by the architect at which the exhaustion adapter will not abort should be 2 x SWL at the minimum exhaustion akin (i.e. basal end of the alive ambit / alpha of crisis range). The adapted changeless affidavit analysis for a exhaustion appropriation adapter is also, as a accepted rule, according to alert its SWL. Breadth exhaustion appropriation accessories are army as an accumulation on a appropriation beam, recommended affidavit analysis ethics are apparent in EN 13155.
25. Aback a exhaustion appropriation adapter is powered by a exhaustion pump, an aural and arresting admonishing accent should be provided to acquaint the abettor and added bodies in the around of the appropriation operation of any abortion of the exhaustion pump and appropriation operation.
26. Whenever possible, the exhaustion appropriation adapter should be adapted with a exhaustion backlog of acceptable accommodation to acquiesce the bulk to be retained for at atomic 5 annual in the accident of the abortion of the exhaustion pump. A acceptable admonishing accent in accession to the backlog exhaustion activity indicator should be fitted, which gives a acutely aural or arresting admonishing to operators and others alive in the around aback the exhaustion in the backlog is beneath 80% of the accustomed alive vacuum.
27. Exhaustion appropriation accessories should be adapted with a large, calmly apprehend barometer or gauges which, with the bulk abeyant from the device, gives the abettor and others in the around of the appropriation operation bright adumbration of the exhaustion condition.
28. Any adjustable corrupt or ‘wander leads’ should be of the armoured blazon and should be adequate as far as accessible from adventitious damage. See EN 13155 for the admonition admonishing and aegis requirements. Note, there are added requirements for angry loads, e.g. bottle handling, and areas breadth bodies are apparent and accent captivation accessories or back-up is required.
29. It is capital that these accessories are anxiously maintained and are subjected to approved analysis and examination:
30. Exhaustion appropriation accessories is clashing for affairs breadth the bulk is acceptable to canyon over cadre or breadth the abrupt abatement of the bulk could accept alarming consequences, e.g. the breach of beef pipes or added casework hit by the falling load.
31. Affliction should be taken to ensure that the abstracts aerial are those for which the adapter was designed. Accurate affliction should be taken aback administration absorptive materials, which may blemish the appropriation accommodation of the attachment. Thin bedding of adjustable actual crave accurate accession to abstain case abroad from the pad due to boundless overhang. If all-important a multi-pad accent should be used. Sliding of absorbed bedding beyond the pads can additionally activity and unless the adapter is distinctively advised for the purpose, absorbed endless should not be lifted. It is capital to position the pads accurately and it is additionally capital to clean all surfaces above-mentioned to the lift, as apart abstracts can annual leaks and accept acquired endless to drop.
32. Beneath LOLER, exhaustion appropriation accessories that are an basal allotment of accouterment are classed as ‘lifting equipment’; those that can be adapted to, and taken off, appropriation accessories are advised to be ‘accessories for lifting’. ‘Lifting equipment’ and ‘accessories for lifting’ are both ‘work equipment’ in accordance with the Provision and Use of Assignment Accessories Regulations 1998 (PUWER).
33. Breadth the accessories is acclimated for assignment purposes, PUWER and added accordant legislation apply.
34. The key requirements beneath LOLER and PUWER are set out in HSE admonition (see Further Reading) and on the HSE web pages.
35. Exhaustion appropriation accessories supplied on the bazaar in the EU charge amuse the accordant Capital Assurance Requirements (ESR) of the Accouterment Directive 2006/42/EC as implemented in the UK by the Accumulation of Accouterment (Safety) Regulations 2008 (SMSR). Further admonition is set out in HSE guidance.
36. Appropriation accessories (e.g. chains, links shackles etc.), acclimated with Exhaustion Appropriation Accessories are accountable to the Health and Assurance at Assignment etc Act (HSWA) 1974 and LOLER and charge appropriately be activated and thoroughly advised accordingly.
37. A accent or accent which is basal with a crane is advised to be allotment of that crane and accountable to the LOLER Regulations as applicative to the crane. Also, in accession and for example, during the administration of accurate pipes, exhaustion appropriation accessories are generally absorbed to the bang of a hydraulic archaeologian either with the brazier still in position or with the brazier removed. Beneath these affairs the archaeologian is advised to be a crane and the agreement of LOLER administer to the excavator.
38. Breadth exhaustion appropriation accessories is acclimated on architecture sites LOLER applies acute the bulk to be abundantly anchored to anticipate crisis from bottomward or displacement. In applications such as the appropriation of industrialised architecture apparatus which accept to be aloft aerial aloft the arena there is a accident that if the exhaustion pump fails and there is cogent or accelerated leakage, there may not be time to lower the bulk afterwards the anxiety rings. Therefore, for aerial lift applications, i.e. aloft 10 metres, assurance accoutrements should be used. These accoutrements should be affianced while the bulk is actuality aerial or some added able agency should be provided of preventing the bulk from falling in the accident of accident of exhaustion (see additionally para 38).
39. Some exhaustion appropriation accessories may be “relevant machinery” and others “interchangeable equipment”, both will be accountable to the Accumulation of Accouterment (Safety) Regulations 2008 (SMSR), as amended.
The accepted standards for exhaustion appropriation accessories include:
40. All associated structural accessories (e.g. jibs, runways and accessories etc.) are adapted to accede with the accordant architecture standards and legislations.
41. The arch hazard associated with the use of exhaustion appropriation accessories is from falling loads. Persons, plant, equipment, and casework in the breadth of operation could be at accident from actuality addled by a bulk which becomes alone from the exhaustion assimilation pads (e.g. due to abortion of the vacuum, afterward accident of power, or due to incorrect appliance or operation etc).
42. Exhaustion appropriation accessories should not be advised as ‘general purpose’ appropriation accessories as they are advised for accurate types of endless and environments. Users should seek admonition from the accessories architect on the adequacy of an absolute accent for added new applications.
43. Employers should backpack out a acceptable and acceptable appraisal of the risks, afore new or absolute exhaustion appropriation accessories are authentic for administration loads. This should accede whether such accessories are adapted and acceptable demography into annual all the affairs of the proposed operation. The appraisal should be agitated out by addition with ability of the actual administration processes, as able-bodied as the capabilities and limitations of this blazon of appropriation equipment. Employees and their assurance assembly with contiguous ability of the hazards and risks complex should be consulted during accident assessment.
44. Safe operating procedures should be able and kept readily accessible for anniversary exhaustion appropriation equipment.
45. The afterward safe alive practices should be advised for admittance in any operating procedures for the use of exhaustion appropriation equipment.
46. Exhaustion Appropriation accessories should be operated alone by competent bodies who accept been abundantly accomplished in the safe use of the accessories and the allegation of any accident assessment. Training should cover:
47. The manufacturer’s instructions for the approved analysis and aliment of the exhaustion appropriation accessories charge be followed.
