Abstract

The invention discloses an enhanced type crane roller, which comprises a roller body, wherein a rope groove is formed in the outer wall of the roller body, a left spiral shaft and a right spiral shaft are respectively arranged at the two ends of the roller body, a double-thread sleeve cylinder is connected between the left spiral shaft and the right spiral shaft, and is arranged in the roller body by an enhanced support plate, a left support plate and a right support plate are respectively arranged at the two ends of the roller body, and a bearing is arranged between the double-thread sleeve cylinder and the enhanced support plate. The enhanced type crane roller has the characteristics that the self weight is light, the wheel pressure is small, the structure is small, the energy consumption is lower, the integral strength and the bearing capability of the roller body are further improved, the structure is light, the anti-fatigue capability is high, and the like.

Description

technical field [0001] The invention relates to the field of electric hoists, in particular to reinforced crane drums. Background technique [0002] Traditional cranes are mainly composed of main components such as lifting mechanism, bridge frame, operating mechanism, and electrical control system. Its defects are as follows: the limit distance from the hook of the electric hoist to the wall is the smallest, the clearance height is the lowest, the crane can work closer to the front, the lifting height is higher, and the overall strength of the crane drum is not enough. Contents of the invention [0003] The purpose of the present invention is to provide a reinforced crane drum, which has light weight, light wheel pressure, compact structure, low energy consumption, and the overall strength and bearing capacity of the drum are further improved. [0004] Technical scheme of the present invention is as follows: [0005] Reinforced crane reel, including a reel, a rope groove...
