Description

Technical Field

[0001] This utility model relates to the technical field of cranes, and specifically to a wheel frame structure for crane movement. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. A bridge crane, also known as an overhead crane, is a type of bridge crane whose bridge structure runs on elevated tracks. The bridge of a bridge crane runs longitudinally along tracks laid on both sides of an elevated structure, while the crane wheel frame moves laterally along the tracks laid on the bridge frame via traveling wheels, forming a rectangular working range. This allows for full utilization of the space under the bridge frame for lifting materials without obstruction from ground equipment. However, existing crane wheel frames all use a beam structure, such as the novel crane end beam disclosed in publication number CN201694745U. This crane wheel frame has the following problems: 1. The length of existing crane wheel frames is mostly fixed, making it impossible to adjust according to usage or assembly requirements, resulting in low applicability. When adjustments or upgrades are needed, custom-made wheel frames are required, increasing customization costs and affecting subsequent efficiency; 2. To ensure service life, existing crane wheel frames typically increase wall thickness to guarantee strength. This method increases the overall weight of the crane wheel frame, increases the overall cost of the crane, and shortens the service life of moving parts. Utility Model Content
