CRANE AND RELATED METHOD OF OPERATION

摘要

The present invention relates to a crane (101). The crane (101) has a hoist (113), movable in at least one lateral direction (X, Y), for performing a lifting operation. A controller (125) is provided for controlling lateral movement of the hoist (113). An imaging sensor (127) is provided for detecting a person in a defined safety region (145, 147). The controller (125) is configured to inhibit operation of the crane (101) when the imaging sensor (127) detects a person in said safety region (145, 147). The invention also relates to a control system for a crane (101) and a related method.

主权项

1. A crane comprising:
a hoist for performing a lifting operation, the hoist being movable in at least one lateral direction; a controller for controlling lateral movement of the hoist; a coupling attached to the hoist for connection to a load; and a height sensor for monitoring a height of the coupling; wherein the controller is configured to inhibit lateral movement of the hoist by permitting only incremental lateral movements when the height sensor detects that the coupling is below a pre-defined operating height or that the coupling is outside one or more pre-defined operating height ranges.
