Operation General

WORKING PRINCIPLE:
The boom is lifted through a gas spring with integrated brake and is controlled by a lever on the operating handle.
This way stone can be picked up from a pallet of approximately 900 mm height. By pressing the lever again the load is
lowered gently into place. Pressing the lever once more lifts the boom up to pick up the next unit.
●
The boom (1) is lifted by a lockable gas spring (in not loaded condition), when the hand lever (2) at the handle (3) is
activated.
●
So it is possible to lift a load (stone slab) from a pallet (up to a high of 900 mm).
●
When activate the hand lever (2) again, the boom can be lowered slowly and the load can be lay down.
●
When activating the hand lever (2) again, the boom is lifted automatically (without load) and is therefore ready to lift the
next load (stone slab).
