In connection with the corresponding hydraulic cylinder a lifting claw represents a compact, lightweight and versatile lifting unit. The lifting claws are screwed onto the collar thread of cylinder series YS. Claws can be placed under loads with minimum clearance.
When operating lifting claws, the following aspects have to be considered: The hydraulic cylinders need to be able to support themselves against the load. The max. force of the cylinder is reduced by 50 %.
Piston plates can be screwed into the piston thread of cylinder series YS. They reduce the surface pressure and prevent the pistons from sinking into the ground. Also when using a piston plate in connection with a lifting claw the cylinder must be supported against the load.
Base adaptors and extension tubes
Extension tubes are mounted onto the bottom of cylinders series YS by means of the base adaptor and two hexagon socket screws (screws are included with the base adaptor). The use of extension tubes adds to the versatility of the standard cylinders.
These load-spreading plates are recommended when slim cylinders are used for lifting operations. They revent the cylinders from falling over and sinking into the ground.
