OPERATION DEVICE FOR MANUAL CONTROL OF A LOAD SUSPENDED IN THE OPERATION DEVICE

摘要

Provided are a method and an operation device for a manual control of a load suspended in the operations device (2) having a housing (20); a first connection device (5), at least indirectly carried by the housing (20), for the connection of the operation device (2) to a device for the lifting and lowering of the operation device (2) with its suspended load; a second connection device (21), at least indirectly carried by the housing, for the connection of the operation device (2) to the load which is to carried by the operation means; a handle (22), which is movably arranged in relation to the housing (20) and the load connection device (21) and which has a rest position between two end positions; a sensor (4) arranged inside the housing (20) for the detection of a motion by the handle (22) in relation to the housing (20) and the load connection device (21), which sensor (4) emits a signal corresponding to the movement of the handle (23) from its rest position; a control unit for receiving the signal and as a result thereof control the lifting and lowering of the operation device (2) with its suspended load, wherein the sensor (4) is an electromagnetic induction sensor.

主权项

1. An operation device for a manual control of a load suspended in the operation device comprising:
a) a housing; b) a first connection means, at least indirectly carried by the housing, for the connection of the operation device to a device for the lifting and lowering of the operation device with its suspended load; c) a second connection device, at least indirectly carried by the housing, for the connection of the operation device to the load which is to carried by the operation means; d) a handle, which is movably arranged in relation to the housing and the load connection device and which has a rest position between two end positions; e) a sensor arranged inside the housing for the detection of a motion by the handle in relation to the housing and the load connection device, which sensor emits a signal corresponding to the movement of the handle from its rest position; f) a control unit for receiving the signal and as a result thereof control the lifting and lowering of the operation device with its suspended load, wherein said sensor is an electromagnetic induction sensor comprising more than two coaxial coil components and a ferromagnetic core component, which is coaxially movable in relation to the coil components.
