Operation

During loading, the vehicle will get lower and the ground pressure on the Liftgate will in-

crease by a weight equivalent to the total weight loaded in to the vehicle. Once the vehicle 

has been loaded with a weight equivalent

 to the maximum load specified for the Liftgate

the platform must be raised slightly and then lowered back to the ground to remove the 

pressure from the ground before loading can continue. This procedure must be repeated as 

soon as the vehicle has been loaded with an additional weight equivalent to 

the specified 

maximum load

.

The weight of the load may not exceed the maximum capacity of the Liftgate.
• 

Platform load = F Load on truck.

• 

Liftgate load = Total load since the platform was last placed on the ground.

The vehicle will rise during unloading. When the platform is raised from the ground, it must 

be lowered back onto the ground before unloading may continue.

Loading and unloading with the platform on ground

4.5 

Loading and unloading with the platform on ground

IMPORTANT

!

 

It is only permitted to drive a forklift on the platform when the platform is resting fully on the 

ground. Otherwise, the load on the Liftgate will be too great. Risk of material damage.
