Attention Inspection, Enhanced Lubrication
Jul 09, 2018

When the loader is working, the working device should ensure that when the bucket cylinder is locked and the boom cylinder is lifted or lowered, the linkage mechanism makes the bucket move up or down or close to the ground to avoid the bucket tilting and spilling the material; When the arm is in any position and the bucket rotates around the hinge to perform the unloading, the bucket inclination angle is not less than 45°, and the bucket can be automatically leveled when the boom is lowered after the unloading. There are mainly seven types of structure types of loader working devices at home and abroad, that is, according to the number of components of the link mechanism, they are divided into three-bar type, four-bar type, five-bar type, six-bar type and eight-bar type; According to whether the steering of the input and output rods is the same, it is divided into a forward rotation and a reverse linkage mechanism. Earthmoving loader bucket structure, its body is usually made of low-carbon, wear-resistant, high-strength steel plate. The cutting edge is made of wear-resistant medium-manganese alloy steel. The side cutting edge and the reinforcing gusset are all resistant to high strength. Made of ground steel. The shape of the bucket cutter is divided into four types. The choice of tooth profile should take into account factors such as insertion resistance, wear resistance and ease of replacement. Tooth-shaped taper teeth and blunt teeth, the wheel loader mostly uses pointed teeth, while the crawler type boot uses blunt teeth. The number of teeth depends on the width of the bucket, and the pitch of the bucket is generally 150-300mm. The tooth structure is divided into two types: integral type and split type. Small and medium-sized loaders are mostly integrated, and large loaders often adopt split type due to poor working conditions and serious tooth wear. The split tooth is divided into two parts, the basic tooth 2 and the tooth tip 1. After the wear, only the tooth tip needs to be replaced.

Since the construction machinery is a special vehicle, the operator should receive training and guidance from the manufacturer, have a full understanding of the structure and performance of the machine, and obtain certain operation and maintenance experience before operating the machine. The "Product Maintenance and Maintenance Manual" provided by the manufacturer is the necessary information for the operator to operate the equipment. Before operating the machine, be sure to read the "Maintenance and Maintenance Manual" and operate and maintain it as required.

Pay attention to the working load during the running-in period. The working load during the running-in period should not exceed 60% of the rated working load, and the appropriate workload should be arranged to prevent the occurrence of overheating caused by continuous operation of the machine for a long time.

Pay attention to the indications of each instrument frequently. If an abnormality occurs, stop it in time to eliminate it. If the cause is not found and the fault is not eliminated, stop the operation.

Pay attention to the lubricating oil, hydraulic oil, coolant, brake fluid and fuel oil (water) position and quality, and check the tightness of the machine. During the inspection, it was found that the oil and water were too much, and the reason should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened. It is recommended that the lubrication point be filled with grease for each shift during the running-in period (except for special requirements).

Keep the machine clean, adjust and tighten the loose parts in time to prevent the parts from being worn out or the parts being lost due to looseness.

At the end of the running-in period, the machine should be forcedly maintained, checked and adjusted, and the oil should be replaced. In short, the requirements for the use of the loader during the running-in period can be summarized as: strengthening training, reducing load, paying attention to inspection, and strengthening lubrication. As long as the maintenance and maintenance of the loader is emphasized and required as required, it will reduce the occurrence of early failures, prolong the service life and improve the efficiency of the operation.
