Abstract

The invention discloses a spreader having an adjustable balanced beam, comprising a beam; a lower end of the beam is provided with a plurality of positioning troughs; the beam is connected with a balancing seat which is provided with a rolling mechanism in contact with the beam and a positioning shaft matching with the positioning troughs respectively. The balancing seat consist of a front and a back board which are arranged at the front and back ends of the beam; the positioning shaft passes through the front and back boards of the balancing seat; one end of the positioning shaft is provided with a handle, and the other end is provided with a fixed pin; the middle part of the positioning shaft is provided with a flute; the front board of the balancing seat is provided with a left and a right handle stop block. The rolling mechanism comprises a connecting shaft which connects the front and back boards of the balancing seat and a roller equipped on the connecting shaft. As the beam of the spreader provided by the invention is provided with the balancing seat which can move along the beam, heavy objects can be lifted easily, rapidly, safely and reliably by adjusting the position relationship between the balancing seat and the beam according to the gravity offset of the lifted heavy object.

Description

technical field [0001] The invention relates to a hoisting device in hoisting equipment, in particular to a beam-type hoisting tool. Background technique [0002] In the manufacture of steel structures or equipment installation, the span of the lifting points of some components is relatively large, resulting in too large angles of wire ropes. At present, beam spreaders are usually used to solve this problem. In the process of using a spreader with a beam, it is often encountered that the shape of the lifted part is asymmetrical and the center of gravity is too large, so it often causes the part to tilt after being lifted, which brings safety hoisting problems. Hidden danger, if the lifting parts are tilted seriously, it will lead to the failure of hoisting at all. This brings great difficulty to the hoisting work, and at the same time, also seriously threatens the personal safety of the operator. The conventional solution is to use wire ropes of different lengths; the seco...
