Abstract
A clamp device for a mobile lift system and a mobile lift system is provided, where the clamp device has a supporting part and two gripper arms movably connected to the supporting part. An actuating system is arranged on the supporting part, where an actuator is connected to each of the gripper arms. The actuators functions as a main cylinder and a slave cylinder respectively. At least one accumulator is connected to the slave cylinder where the accumulator creates an opposing pressure as a result of the gripper arms' position.
Claims11
A clamp device for a mobile lift system comprising:
- a supporting part with an interface configured to be connected to a corresponding interface on a lift unit in the lift system;
- a gripper arm arranged in each end of the supporting part, where the one end of the gripper arm is movable connected to the supporting part and the second end is configured to grab an article;
- an actuating system arranged on the supporting part and connected to at least one of the gripper arms, where the actuating system comprises at least one actuator configured to move the at least one gripper arm between an open position and at least one clamping position;
- wherein the actuator system is configured to grab an article with a clamping pressure and to adjust the clamping pressure based on a position of the gripper arm, wherein the clamping pressure is gradually adjusted between the open position and the at least one clamping position, and
- wherein the actuating system is configured to apply a substantially constant pressure in a grip direction and to create an opposing pressure which combined create a resulting clamping pressure.
