Description

Technical Field

[0001] This utility model relates to the technical field of equipment maintenance tools, specifically a tool for disassembling and assembling the hydropneumatic suspension of a heavy-duty mining truck. Background Technology

[0002] To reduce operating costs in open-pit mining, manufacturers typically use high-powered, heavy-duty mining trucks as transportation. As the load capacity of these trucks increases, so do the structural components. For example, the hydropneumatic suspension of a 100-ton or larger mining truck can weigh around 1.5 tons, making traditional manual disassembly and assembly methods insufficient. Lacking specialized maintenance tools, manual chain hoists are often used for disassembly at the maintenance site. This is not only inefficient but also poses serious safety hazards, easily leading to issues such as weld cracking at lifting points and chain breakage, which can easily damage spare parts and cause personal injury.
