Our guidance on risk of vehicles falling off 2-post vehicle lifts in motor vehicle repair (MVR) has been issued to the enforcing authorities (HSE and local authorities) about the risks of vehicles falling from 2-post lifts where arm locking systems are either missing or have ceased to work.
The guidance follows 2 accidents, one fatal and the other very serious, in which vehicles falling off this type of lift struck mechanics working below.
It was agreed with representatives of the MVR industry that arm locking systems should be fitted to all these lifts. Therefore, any remaining 2-post lifts without arm locking should now have been taken out of use or scrapped.
Problems with the design, installation, use and maintenance of arm locking mechanisms continue to cause concern in newer machinery. Some new Chinese-manufactured 2-post lifts have been found where the locking mechanism has been poorly manufactured and failed to work from installation or within a short period of use.
This guidance emphasises the importance of daily checks on the locking mechanisms and other critical parts of 2-post lifts. These include:
- ensuring the support arm rubber mounts are in a serviceable condition
- ensuring that the arm lock mechanism does operate satisfactorily
- checking that all controls operate
In addition, there are several basic safety measures that you should take when using 2-post lifts:
- ensure you follow the lifts manufacturer's instructions on the capability limits of the lift, in particular it weight limits and if it is suitable for larger vehicles (dimensions and stability)
- you need to identify the correct jacking/lifting points for the vehicle (check the vehicle user manual if necessary)
- ensure the lifting arms are carefully positioned at the correct jacking/lifting points for the vehicle
- consider the weight distribution of the vehicle especially, if large parts (for example engine or gearbox) are removed from the vehicle or by the application of force (for example forcing off rusted on bolts) which could affect the stability of the vehicle being lifted
- lift the vehicle a short distance to check that the arms have locked by applying some force to them and the pads are properly positioned, before fully elevating the vehicle
Lift installers need to be competent and the flooring needs to be of appropriate strength.
If there is no supporting evidence for the flooring specification, a series of test holes may need to made and expert opinion obtained. One way in which businesses can help assure themselves that a lift is installed correctly is by using installation engineers who are accredited - the Garage Equipment Association (GEA) operate a lift engineer accreditation scheme.
