1. The lift fails to ascend or has weak ascending force (1) The pressure adjustment of the relief valve does not meet the requirements Adjust the pressure to the required value. The relief valve plays a crucial role in controlling the hydraulic pressure within the lift system. If it’s not set correctly, the pressure might […]

Fixed lift products can be roughly classified into several types according to their operation modes, including scissor lifts, double-scissor lifts, guide rail lifts, telescopic cylinder lifts, and wall-mounted lifts. Scissor Lifts Scissor lift fixed lifts are specialized equipment widely used for high-altitude operations. Their scissor mechanical structure endows the lifting platform with high stability after […]

Tyres are the only components that come into contact with the ground during driving. They may seem unremarkable and are often dirty, but poor maintenance can often be a potential hidden danger for accidents. As the ancients said, “Read ten thousand books and travel ten thousand miles.” However, many car owners don’t have such a […]

Brake shoes, commonly known as brake pads, are consumable items. They gradually wear out during use. When they are worn to the limit position, they must be replaced; otherwise, the braking effect will be reduced, and even safety accidents may occur. Brake shoes are closely related to life safety and must be treated with great […]

Regardless of the type of machinery, different lubricating oils are prohibited from being mixed for use, and reducers are no exception. For reducers, the positions of the oil level plug, drain plug, and breather are determined by their installation locations. When it comes to the use, inspection, and maintenance of the lubricating oil in reducers, […]

Hooks can be classified into two types according to their shapes: single hooks and double hooks. They can also be divided into three kinds based on the manufacturing process: laminated hooks, forged hooks, and cast hooks. Currently, the commonly seen hooks are forged single hooks. Cast hooks are not permitted for use on cranes. Hooks […]

1. Safe Positioning During crane operations, it is extremely hazardous to stand under the boom, beneath the load, in the lifting zone before the object is hoisted, in the triangular area formed by guide pulley cables, around fast-moving cables, or in the direction of tension from inclined hooks or guide pulleys. If an emergency arises, […]
