In industrial production, logistics warehousing and other scenarios, the skidding of crane tracks will affect operating efficiency and bring safety hazards. Understanding the causes of skidding and taking corresponding measures is the key to ensuring the safe and efficient operation of equipment.
Insufficient friction causes skidding
If there are impurities such as oil, water, and frost on the track surface, the friction coefficient will be reduced and skidding will occur. When solving the problem, the track needs to be cleaned regularly and drainage facilities should be set up in areas prone to water accumulation. After the wheels are worn out after long-term use, the tread shape changes, the contact becomes worse, and the friction is reduced. In this regard, regular inspections are required. Mild wear can be repaired by surfacing and grinding, and the wheels need to be replaced in severe cases.
Abnormal operating parameters cause skidding
Starting or braking too hard, the wheel speed changes suddenly, and the static friction cannot be converted in time, which can easily cause skidding. Optimizing the control system, using soft start and soft braking technology, and strengthening operator training can avoid it. Overloading operation causes uneven wheel pressure, exceeding the friction load range. Strictly complying with the rated lifting capacity and installing an overload limiter are the key.
Installation and deformation problems cause slippage
When installing the track, the horizontal deviation, uneven joints, and inconsistent spacing will cause uneven force on the wheels, causing slippage. The installation must be strictly operated according to the standard, measured with high-precision instruments, and carefully inspected after completion. Deformation of the crane structure, such as the deflection of the main beam, will affect the wheel track and wheel pressure. Regular inspection of the structure and timely correction or replacement of deformed parts can ensure that the wheels and tracks are well matched.
Environmental factors affect slippage
Under extreme temperatures, the performance of the track and wheel materials changes, becoming brittle at low temperatures and deforming at high temperatures. Choose cold-resistant materials for low-temperature operations and lay heating cables; strengthen heat dissipation at high temperatures, check deformation and adjust. When outdoor cranes encounter strong winds, the wind force exceeds the friction force, which will cause slippage. Stop operations before strong winds, and anchor the crane with windproof rail clamps and other devices.
Through targeted solutions, the probability of track slippage can be reduced, the stable operation of the crane can be guaranteed, and production efficiency can be improved.
