Lifting, Lowering, and Transporting Loads 

 

DANGER

 

Danger to life, risk of injury from lifted vehicles

 

 

Only load lift and load pick-up devices centrically by positioning the center of gravity in the 

middle.  

 
 

Safety Notes

 

 

Always keep the movement range of the lift free.  

 

Keep the movement range of the load and the load pick-up devices free.  

 

Complete lifting of vehicles with one or more lifts is not permitted.  

 

Always shut down and secure the lift immediately in case of malfunction. Always have 

malfunctions repaired immediately. 

 

Do not operate the lift with compressed air containing condensate or dirt. 

 

For work with strongly adhesive underbody sealants or lacquers, cover the piston rod. 

 

Keep the piston rod and the pins of load pick-up devices free of sand and dirt. 

 

Disconnect the lift from the compressed air supply at the end of work or before longer breaks. 

 

Remove the removable pump rods after each work process. 

 
 

CAUTION

 

Damage to lifts and vehicles from load pick-up devices and extended piston rods

  

 

Piston rods must always be completely retracted when entering or leaving workshop pits and 

lifting platforms.  

 

A sufficient distance must exist between load pick-up devices and vehicle. 

Considerable longitudinal forces can occur when vehicle axles are lifted.

 

 

Disengage the handbrake and shift to idle, so that the wheels can roll. 

 

Raising a vehicle

 

 

Lift the vehicle slightly with the lift at the load pick-up point. 

 

Check for safe support and secure seating of the vehicle. 

 

Lift the vehicle to the desired height. 

 

Secure the vehicle against rolling off, for example with drag shoes. 

 

Secure lifted vehicle with supporting bridges/A-frames. 

 

Lowering the vehicle

 

 

Remove the roll-away protection from the vehicle. 

 

Lift the vehicle slightly with the lift and remove the supporting bridges/A-frames. 

 

Lower the vehicle slowly. 

 

Retract the piston rod [1] completely and make sure that the support plate is on the piston rod. 

 

Transporting vehicle parts

 

 

Position the vehicle part on a lift with a suitable transmission plate in centered position.  

 

Secure the vehicle part with chains or belts. 

 

Retract the piston rod [1] completely and transport the vehicle part.
