Vehicle hoists are produced by a number of manufacturers globally. They come in a range of configurations and are designed to meet the particular needs of the workshop. For instance there are models that are designed for use where the ceiling height (e.g. Shorty lift) may be an issue, there are models that are completely mobile (e.g. Specialty lifts) and individual lifting machines that can be linked together electronically and used on trucks and buses.
Generally they come in the following types and groups:
Each of these types have one common feature that should always be adhered to: NEVER exceed the safe working load for the lift and always follow the manufacturer loading and operation instructions.
All lifts used in automotive workshops must have a safety locking device built into the design to ensure that the lift cannot collapse when it it raised with a vehicle on it and it is essential that the locking device is engaged when the lift is raised before anyone is allowed to proceed with a task underneath the vehicle.
Most jurisdictions require the lift to be registered with the local safety and health inspectorate, are generally required to be inspected and certified as fit for use on and annual basis. If unsure look for the manufacturers identification plate and a current registration label before using the lift.
