How to Maintain a Loader?

Loaders are the most widely used construction machinery and play an important role in engineering construction. In order to improve the working efficiency of loaders, daily maintenance of the loader must be paid attention to in order to ensure that loaders are in good working condition. Maintenance technology of loader is emphatically expounded, and its common faults are analyzed, and preventive measures are put forward.

1.Necessity of daily maintenance of the Loader

Wheel loaders are widely used and applied in engineering construction. They have become the most commonly used construction machinery in construction. Their production and sales have always been the first of all kinds of construction machinery. Because of its wide application in engineering, loaders have developed rapidly in recent years, and their technical level has been improved year by year. Loader's working environment is often harsh, and the construction workload is large, the use of time is long, resulting in reduced efficiency, and economic losses. Therefore, in the process of using, we should pay attention to the daily repair and maintenance of the loader. The necessary daily repair and maintenance can effectively reduce the wear and tear of loader parts, ensure the working state of loader and extend its service life. Daily maintenance can replace some vulnerable parts to ensure their uniform wear, avoid uneven wear and prolong their service life. In addition, maintenance according to the use of loaders can effectively eliminate the hidden dangers of loaders themselves in construction, avoid some safety accidents, reduce maintenance costs and ensure the construction period.

2.Loaders Common Faults

Common Engine Failures

We mainly analyze the common faults of diesel engine. We should carry out routine checks on the main components of diesel engines and deal with the problems found. If there are problems in the cooling system, such as the water temperature alarm light on the IECU, it is necessary to check the cooling system, including the cooling water level, whether the thermostat is damaged, whether the radiator is blocked, whether the fan is working properly, the working condition of the cooling water pump, and so on. The failure of other institutions and systems is also analyzed by this method.

3.Daily maintenance of Loaders

Every day

Check whether there is oil, water and gas leakage and overheating of parts; Check diesel engine oil, brake fluid and hydraulic oil level; Check tire pressure and damage; Check instrument and light; Press butter into each hinge point.

Every week

Check bolts of transmission shaft before and after tightening; Check oil level of gearbox; Check and adjust the oil quantity of foot brake intensifier; Check throttle control variable speed control system; Check the level of battery and apply Vaseline on battery wiring head; Check the tightness of wheel rim and brake disc bolt bridge bolt; Check the tightness of generator fan belt. Check the fastening condition of each fastening bolt. 

Every month

Check the operation of the engine; Check the working condition of the hydraulic system; Check the performance of the steering system; Check the performance of brake system, change brake oil; check the oil level of front and rear axles; 6. Replacement of engine oil and diesel oil filter

Every year

Replacement of front and rear axle gear oil; Replace hydraulic oil, clean or replace oil filters, clean oil tanks; Repair engines according to engine instructions; Dismantle gearboxes and torque converters; Dismantle front and rear axles; Inspect welds in all parts of the machine; Inspect the working condition of hydraulic system; Inspect the performance of steering system; Inspect brake system. System Performance; Check Electronic Control System.
