First Claim
Patent Images
1. A hook-on grab bucket, comprising:
- first and second half-scoops movably disposed relative to one another between an open position and a closed position;
an hydraulic cylinder for moving said first and second half-scoops between the open position and the closed position;
a sensor disposed to monitor an opening angle of said half-scoops, said sensor being integrated in said hydraulic cylinder and generating an actuating-travel signal corresponding to an actuating travel of said hydraulic cylinder; and
a control and monitoring device connected to said sensor.

Abstract
A grab bucket, in particular motor-driven underwater grab bucket, has first and second half-scoops. The scoops can be moved relative to on another from an open position into a closed position by a hydraulic cylinder. The opening angle of the half-scoops is monitored by a sensor which is connected to a control and monitoring device. The sensor is integrated in the hydraulic cylinder and generates an actuating-travel signal which corresponds to the actuating travel of the hydraulic cylinder.
