Correct operation and timely repair
In the operation of side-loading wheel loader, the operation level and operation methods of the operators and the ability to find faults are also issues that cannot be ignored. The working place in the tunnel is narrow, which invisibly increases the difficulty of operation. Those with a higher level of operation can shorten the working time in the hole, prevent knocking, reduce the damage of the bucket teeth, reduce consumption, and find it in time after a fault To prevent the wheel loader from breaking down on the working surface. The side unloading wheel loader should be repaired in time after it appears faulty, so as to avoid small losses, which will make the wheel loader unable to operate during the operation process. Predictive repairs can reduce the damage caused by security incidents and personnel.

wheel loader repair
When the side unloading wheel loader is working in the tunnel, the road surface in the cave is covered with debris after the explosion. These gravel have edges like blade ←, and the tire scratched by it is often impossible to correct. Because the price of side-loading wheel loader tires is relatively high, the economic benefits of the construction unit cannot be guaranteed without adopting effective protective measures and reducing tire consumption.
Main problems to be noted in the tunnel operation of the side unloading wheel loader
China Communications News: wheel loader maintenance is often used in highway and railway engineering construction. Tunnel construction projects are often used. Depending on the size of the tunnel and the construction environment, the selected Caterpillar loading machinery is also different. In some large-scale culvert construction, the side unloading wheel loader is often used as the loading equipment. However, tunnel construction is different from open-air construction, and the side loading wheel loader should pay attention to the following five aspects during the use process.
Useful safety measures
In the course of tunnel construction, landslides, rock bursts, and rockfalls on the top of the tunnel often occur. If there is no useful protection method, it will inevitably cause damage to equipment or personnel. Side unloading wheel loader is more likely to encounter risks in the process of slagging in the hole, so pay special attention to safety protection operations. When selecting a model, it is best to select a model for tunnel construction with protective equipment, and it can be modified without its own protective equipment. The most vulnerable parts of the side unloading wheel loader during the tunnel construction process are the cab, working hydraulic cylinder and engine. The cab is the main point of protection, because if it is damaged, it may endanger the life of the operator. For models without self-protection equipment, a steel plate with a thickness of 6-8 mm can be installed above the cab and 15-20 cm away from the top of the cab. The size of the steel plate cannot be directly hit by the falling rock on the top of the cab to the windshield. The glass shall prevail. The steel plate is supported by four uprights, and the uprights are fixed to the frame. This steel plate is like the safety helmet we are wearing during construction. This modification method has obvious protective effect in actual use. Each hydraulic cylinder of the wheel loader bucket is exposed under the working surface during operation. When stones fall, sometimes the piston rod of the hydraulic cylinder may be damaged, resulting in damage and deformation of the piston rod surface. In order to prevent damage to the piston rod, it is also possible to suppress the protective cover of the hydraulic cylinder and install it on the hydraulic cylinder. Because the engine has its own hood, it can adopt appropriate protection measures according to actual needs. After strengthening the protection of these key points, although it cannot completely resist the large landslide incident, the protection effect on the frequent and small-scale landslides and falling rocks is still obvious.
