What Failures Will the Loader Encounter?

 

1, idle automatically forward, put into forward gear can also be normal driving, put into backward gear when the machine stops, can not walk. The working pressure of each gear is normal.

 

Failure causes.

Forward clutch master and slave plate sintering and clamping.

Forward clutch piston jamming, support check valve blockage.

 

Removal method.

Disassemble the forward clutch, clean the oil channel, replace the main and driven friction plate and related damaged parts, clean the relevant parts, replace the outer seal ring, clean and unclog the check valve, replace the clutch friction plate, inner and outer seal ring.

 

2, the whole machine suddenly does not move forward, not backward, variable speed working pressure is normal.

 

Cause of failure.

(1) for the variable speed distribution valve failure or (40F, 50D, 50F) accumulator damage variable speed valve pneumatic control valve stem stuck or damaged.

(2) the oil feed path blocked.

(3) Accumulator oil circuit blockage.

(4) Pneumatic control shut-off valve failure.

 

Removal method.

Clean the isolation stem of the variable speed valve or replace the pneumatic control valve to unclog the relevant oil circuit, repair or replace the pneumatic control shut-off valve. Need loader apparatus contact wisdom big view.

 

3, the machine normal driving process, hanging second gear suddenly does not work, check the gear and the rest of the working pressure of each gear are normal.

 

Cause of failure.

The gear clutch shaft broken.

 

Removal method.

Replace the clutch shaft, re-adjust the bearing clearance.

 

What Failures Will the Loader Encounter?cid=2


4, the engine idle or high-speed dynamic rotation, the ammeter indication does not charge.

 

Cause of failure.

Generator armature and magnetic field wiring insulator damage, slip ring insulation breakdown, silicon diode breakdown, short circuit or disconnection, voltage regulator contact burnout, stator or rotor coil overlap or disconnection.

 

Exclusion method.

Check and repair the damaged parts, replace the slip ring, replace the diode, replace the regulator, repair the stator or rotor coil.

 

5, hand-controlled brake valve is connected, easy to pop up.

 

Cause of failure.

Air pressure is low to 0.35MPa, hand control brake valve damage, sealing is not tight, air control shut-off valve damage, parking stationary gas chamber piston on the seal is damaged.

 

Removal method.

Check the air compressor work whether the pipeline has no air leakage, replace the damaged seals.

 

6, when braking, to one side of the deflection.

 

Cause of failure.

The two front wheel brake disc and friction pad gap is not the same, the two front wheel friction pad contact area difference, a front wheel piston air, a front wheel caliper deformation, two front wheel air pressure is not the same, a side wheel friction pad oil and water wet.

 

Exclusion method.

Check the brake disc and friction pads such as damaged replacement, check and replace the friction pads, according to the correct method to exhaust the air, replacement, inflatable chamber regulations and air pressure consistent, cleaning and blowing dry.

Reasonable Operation Of Track Bulldozer

图片
The  Track Bulldozer   has the greatest influence on the transmission oil temperature due to the external resistance and the maximum output torque during the shovel operation. If the small throttle is used for a long time to operate the torque converter in the inefficient zone, the transmission oil temperature will rise. If the large throttle is used during frequent shifting, it will cause severe impact on the machine and increase the temperature of the transmission oil. To this end, the operator should reasonably control the amount of bulldozer and the timing of the blade lifting and lowering. The soil feeding distance should not be too long, so as to prevent the use of small throttle for a long time. We are  Track Bulldozer Supplier , specializing in the production of machinery and equipment, welcome to consult and order.

How to Choose the Right Bulldozer?

图片
  Purchasing a bulldozer is a significant investment, whether you're in the construction business or need one for specific projects. To ensure you make an informed decision and get the   right bulldozer   for your needs, here are four essential tips and things to know before buying one: 1. Define Your Requirements and Applications The first step in   buying a bulldozer  is understanding your specific requirements and applications. Consider the following: Size and Capacity:  Bulldozers come in various sizes and capacities. Determine the size that can handle your typical projects and the type of material you'll be moving. Attachments:  Many bulldozers can be equipped with various attachments, such as blades, rippers, and winches. Assess which attachments you need for your tasks. Terrain:  Consider the type of terrain you'll be working on, as this can affect the tracks or tires your bulldozer should have. Understanding your specific needs will help you narrow down your options

No Steering Failure of Crawler Hydraulic Steering Bulldozer

图片
  During the use of the bulldozer, due to various reasons, the bulldozer is difficult to turn, cannot turn, cold cars can turn, hot cars can not turn. After the occurrence of these failure phenomena, according to the use time of the bulldozer and the occurrence process of the failure, the classification analysis should be carried out to check the truth, which can avoid unnecessary disassembly and reduce the internal pollution of the machine. The following   Bulldozer Suppliers   introduce common fault phenomena such as bulldozers and related knowledge of inspection and elimination. When the  Dozer  is in use, it suddenly fails to turn on both sides. The overflow valve at the oil inlet of the directional control valve assembly can be disassembled. The reason is that the oil is too dirty, the impurities in the oil wear or strain the surface of the overflow valve core and the inner cavity of the valve body, so that the valve core is stuck in the position where the oil return is turned on,
