Abstract

The invention discloses a C-shaped lifting appliance and an appliance for lifting a thrust wheel of an excavating machine. The C-shaped lifting appliance comprises a main lifting plate, two first limiting plates and two second limiting plates, wherein the main lifting plate is a C-shaped plate body of certain width; a groove is formed in the middle of a lower hook of the main lifting plate; the first limiting plates are respectively fixed on the inner side surface of the main lifting plate in positions on two sides of the groove, and are arranged in the width direction of the main lifting plate; the second limiting plates are respectively fixed on the outer side surface of the main lifting plate in positions on two sides of the groove; and each first limiting plate and an adjacent second limiting plate form a two-stage step. The appliance for lifting the thrust wheel of the excavating machine comprises a rigging and the C-shaped lifting appliance hung on the rigging. Due to the C-shaped lifting appliance, the thrust wheel of the excavating machine can be limited in a plurality of manners, so that the thrust wheel can be lifted reliably, and danger of slipping caused by improper lifting is avoided during the assembly of the thrust wheel.

Description

technical field

[0001] The invention relates to a sling, in particular to a hoisting device for supporting rollers of an excavator. technical background

[0002] The shell of the excavator roller is in the shape of a three-step stepped shaft shell with two small ends butt welded, and a convex ring-shaped weld is formed at the butt joint of the two three-step stepped shaft shells. The existing excavator supporting wheel assembly adopts manual handling or a simple L-shaped spreader for a single hoisting operation. The efficiency of manual handling is low and the labor intensity is too high, and the L-shaped spreader is easy to fall off during the transfer process, which poses a safety hazard. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a C-type spreader capable of reliably hoisting the rollers of the excavator, and to provide a hoisting device for the rollers of the excavator using the aforementioned C-type sp...
