Description

Technical Field

[0001] The present application relates to the technical field of jib cranes, and in particular to a fully automatic walking multi-section lifting and elevation jib crane. Background Art

[0002] The working strength of the cantilever crane is light. The crane consists of a column, a slewing arm slewing drive device and an electric hoist. The lower end of the column is fixed to the concrete foundation by anchor bolts. The cycloidal pinwheel reducer drives the cantilever to slew. The electric hoist runs straight left and right on the cantilever I-beam and lifts heavy objects. The crane jib is a hollow steel structure with light weight, large span, large lifting capacity, and is economical and durable. The built-in walking mechanism uses special engineering plastic wheels with rolling bearings, which have low friction and light walking; the small structural size is particularly conducive to increasing the hook stroke.
