Document Type and Number:
Japanese Patent JP2020101073
Kind Code:
A
Abstract:
To provide a device for gripping a columnar member such as a utility pole which, even in the presence of obstacles or in working in a narrow space, allows easy and safe building of the columnar member without, e.g., breaking the columnar member, and thereby can improve the working efficiency and the working safety.SOLUTION: A device 100 for gripping a columnar member comprises: a pair of gripping jaws 110A, 110B facing each other to be capable of gripping a circumference of a utility pole 1; and a control device 320 to control the force of the gripping jaws 110A, 110B gripping the utility pole 1. The control device 320 causes the utility pole 1 to be gradually lowered by its own weight by repeating the operations of: weakening the gripping force of the gripping jaws 110A, 110B from a state where the utility pole 1 is gripped by the gripping jaws 110A, 110B, thereby lowering the utility pole 1 by its own weight by a prescribed amount in the longitudinal direction thereof; and then restoring the gripping force of the gripping jaws 110A, 110B to grip the utility pole 1.SELECTED DRAWING: Figure 1
