jib crane

When we use a car mounted jib crane, due to unknown reasons, the equipment shakes to varying degrees during lifting. There are many reasons for the shaking of a cantilever crane during lifting. What are the reasons for this?

The lubrication effect of the slide inside the crane arm has deteriorated, resulting in difficulty in extending or retracting the crane arm when lifting goods, which puts a lot of pressure on the equipment and causes shaking. So we need to perform maintenance work on the car mounted small crane to avoid rusting of the inner slide of the boom.

When the load exceeds the maximum applicable weight, the small crane will cause vibration during the contraction process. Another situation is that the precision of the crane arm process of the vehicle mounted crane does not meet the standard, resulting in a decrease in weighing capacity, which leads to actual weighing capacity not matching the description, resulting in overload caused by errors during use.

If the sliding arm is damaged, continuing to use the vehicle mounted crane will cause shaking due to the weight of the cargo when the arm is extended outward. If there is too much resistance and friction during recovery, the shaking will be even more severe.

The boom of the vehicle mounted crane is manually extended and retracted by an electric motor and a steel wire rope pulley system. When the boom is fully extended, due to the principle of leverage, the lifting capacity slightly decreases. If the cargo is lifted according to the lifting weight without expansion and contraction, it will bring pressure to the entire vehicle mounted crane, causing vibration
