Abstract
PURPOSE: To prevent overturning by computing an overturning moment based on detection signals from a load sensor and a stroke sensor, and outputting a closure actuation signal to a solenoid operation valve when the computed value reaches a preset safety reference value. CONSTITUTION: As a work W is clamped and lifted, load of the work W is detected by a pressure sensor 27, and as a clamp arm is side-shifted right or left while clamping the work W, its shift quantity is detected by a stroke sensor 28. A control device 30 computes an overturning moment based on input signals from both sensors 27, 28, and allows side shift of the clamp arm 6 till the computed value reaches a safety reference value. When the computed value reaches the safety reference value, a closure signal is outputted to solenoid operation valves 31, 32 in a hydraulic circuit to control actuation of a clamp cylinder 5, and the solenoid operation valves 31, 32 disconnect the hydraulic circuit to lock side shift by the clamp cylinder 5.
