DEVICE FOR HOISTING AND CONTROLLING LOADS

摘要

In the field of hoisting and controlling hoisted loads, a hoisting device for hoisting a load includes a support beam, two load carrying units, structured to be slid along the support beam and being structured to hold the load, at least one counterweight structured to be slid along the support beam, at least one sensor capable of measuring the weight force held by the load carrying units, a first driving unit structured to slide the load carrying units, a second driving unit structured to slide the counterweight, a third driving unit structured to hoist the load, a hooking point structured to be hooked from a crane, and a processing unit structured to receive the information produced by the sensor and structured to operate the first driving unit, the second driving unit and the third driving unit.

主权项

1. A hoisting device (1) for hoisting a load (9), the hoisting device (1) comprising:
a support beam (2), two load carrying units (3, 4), structured to be slid along the support beam (2) and being structured to hold the load (9), at least one counterweight (5) structured to be slid along the support beam (2), at least one sensor unit in each load carrying unit (3, 4), each sensor unit being configured to measure the weight force held by the load carrying unit (3, 4), a first driving unit structured to make the load carrying units (3, 4) slide along the support beam (2), a second driving unit structured to make the counterweight (5) slide along the support beam (2), a third driving unit structured to hoist the load (9), a hooking point (13) structured to be hooked from a crane, and a processing unit structured to receive the information produced by the sensor unit and structured to operate the first driving unit, the second driving unit and the third driving unit, in order to move the counterweight (5) to a position such that the centre of mass of the system containing the load (9) and the hoisting device (1) is vertically aligned with the hooking point (13).
