Crane with overload locking device

Abstract

The invention relates to the field of lifting equipment, in particular to a crane with an overload locking device. The crane comprises a crane body and a rotating cavity formed in the crane body, a rotating block is rotatably arranged in the top wall of the rotating cavity, and a groove with a downward opening is formed in the bottom wall of the rotating block; swinging hoisting walls are symmetrically arranged on the top wall of the rotating block in a front-rear mode; and a first rotating shaft is arranged between the two hoisting walls. According to the crane with the overload locking device, the device can be locked when the hoisting weight is greater than the rated weight of the device, meanwhile, a buffer device is arranged in the device to buffer cargo after an accidental break in ahoisting cable of the device, so that the hoisted cargo is protected; and the device can move freely, meanwhile, the distance between a front wheel and a rear wheel can be increased before hoisting,so that greater support is provided when the device hoists, more safety is achieved, and production, promotion and use are convenient.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a crane with an overload locking device. Background technique [0002] When people are hoisting heavy objects, the hoisting equipment is often damaged due to the inability to estimate the weight of the hoisting objects. The traditional hoisting equipment does not have an overload locking device, and it is easy to break the hoisting rope when lifting excess cargo by force. There is no protective device, and the goods will be damaged by direct collision with the ground after the hoisting rope breaks. Therefore, it is necessary to set up a crane with an overload locking device to improve the above problems. Contents of the invention [0003] The object of the present invention is to provide a crane with an overload locking device, which can overcome the above-mentioned defects of the prior art, thereby improving the practicability of the equipment. [0004] The technical solutio...
