Correct operation using crawler tractors traveling

When the bulldozer steering, brake pedal should be smooth to avoid beating occurred when cornering. After turning the brake pedal should be loose, and then release the joystick. If the turning radius is large, you do not step on the brake pedal. No heart to avoid making situ rotation speed bulldozers,Mechanical Crawler bulldozer derailment caused the accident.
3, driving on the ramp
Different models have different climbing ability swamp hydraulic crawler dozer (typically 30 °), the same structure can adapt bulldozer slope and terrain are not the same. The driver should be familiar with the type of climbing limit, avoid the cause, lack of capacity and downhill landslide phenomenon.
Before the uphill, should be based on topography, slope size and length, select the appropriate speed gear, climbing halfway shift allowed. Uphill, bulldozers should run hillside transverse vertical angle was not allowed to travel on steep slopes laterally; lower blade may be appropriate, so as not to affect the eye, and in the event of landslides can quickly make the blade of the bulldozer to help brake; uphill on the way in case they turn off the engine, should immediately stop the oil, put down the shovel and the emergency brake. When the slope can not be shut down, should be replaced by reverse slowly slide into the base (side brake side slip), and then start to persuade; if not stop the oil, and slid forward Dangdang bit, due to the anti-spread power engine fire caused by reversed, causing the air filter out fuel injection. In case of reversal of fire, they should quickly close the throttle, brake and bulldozers to live. Before restarting, check the shift lever is in the neutral position.
When the bulldozers downhill, should use low gear small throttle position, and use the brake pedal.

1, the speed of advance and retreat
When shifting Guadang should first push forward the throttle handle to a low idle position, then the main clutch lever pushed to the front, so that the main clutch, the role of the main brake clutch small, so that the input shaft of the transmission stops . At this point, you can shift to the desired gear benchmark correctly, then retreat into the rod forward or backward position (when the bulldozers move forward, pull back the lever back and forth, back when it is pushed forward). After Guadang, pull back the throttle lever to increase the engine speed, and smoothly connected to the main clutch, bulldozers began traveling.
When the bulldozer driving, should the main clutch lever pulled last party, not on the half-engaged position. Because the main clutch engagement will increase the friction plate semi wear.
Bulldozer transmission generally have five forward gears and four backward gear. You can use the lever back and forth to change the direction of travel of the bulldozer.
Bulldozer when the job should be possible to run at top speed, in order to improve operational efficiency. But the driver should always pay attention to whether the normal operation of the engine and found that black smoke when the engine and exhaust overheating, should be appropriately reduced speed.
2, steering
Hydrostatic bulldozer When traveling in turn, can be turned to the side of the steering clutch lever is pulled back, the steering clutch, so the corresponding side track speed slows down, bulldozers began to shift. To make a sharp turn bulldozers, except separate steering clutch, it should also depress the brake pedal corresponding generally run only when Ⅰ gear allows for sharp turns. When not using the brakes should not be placed on the foot brake pedal, otherwise it will lead to brake with wear and fuel consumption increases.

Rocky ridge or cliff by bulldozer

When the Hydrostatic dozer required by larger land package or cliff Hom and other obstacles should slowly and diverted. When you reach the apex body will be tilted forward at the moment, should be promptly separated from the clutch, so that the front of the small dozer supplier slowly ground, then engage the clutch before continuing forward. Exit ramps are not allowed to cross the obstacles, obstacles do not pull at the drive onto the steering rod.
Through the rocky beach, the advance to choose the right path, had been opened, on the way to minimize the steering, and should low gear, small throttle driving, are not allowed in high gear, the throttle driving and sharp turns on a bumpy rocky beach.

Tractor bulldozer

Bulldozer trapped car self

When the Swamp crawler dozer in a great location moisture or rain in muddy sections were bulldozer operations, inspection easy trap car phenomenon. There are two ways to save themselves after the trap car.
(1) If the bulldozer on the ground to the front of the car is not too deep depression when the Hydrostatic truck Bulldozer, dozer manipulate the joystick, the use of hydraulic blade will drop from the machine head, so that the tail under pressure; then manipulate dozer lever, so Hydraulic lifting the blade, so that the nose dropped, the tail is reset (depending on the trap car space above process can be repeated operating conditions), and then hang backwards Ⅰ block bulldozers, appropriately increase the throttle, clutch master gear together, so bulldozers backwards a short distance (usually every rewind 5-10cm), then quickly separated from the main brake pedal and clutch lever. Repeated so many times, you can successfully be stuck out backwards Crawler tractor dozer.
(2) If the above method can not be trapped bulldozer out backwards when available rope is fixed at one end to a tree or post, the other end of the rope is fixed on one or both sides of the bulldozer caterpillar (if Only one side tracked stuck, you are stuck on a fixed rope crawler; if both sides are tracked and trapped in deep, then use two ropes fixed on both sides of the crawler), and then start the engine, hang backwards Ⅰ file (or a forward gear Ⅰ), slowly rotating tracks, make rope roll out of the track on top of the bulldozer.

How to distinguish the authenticity of bulldozer accessories

Quality is the basic guarantee bulldozer parts construction equipment to work, but because of the needs and interests of the maintenance of mechanical drive, making the emergence of a wide range of varying quality on the market, imports of construction machinery parts.
Currently on the market, imports of construction machinery parts (bulldozer parts) including whole plant pure components, professional supporting factory quality components, coupled with exquisite genuine parts packaging, but it is from South Korea and China's Hong Kong, Taiwan and other Asian countries and regions transport imports of non-indigenous whole plant parts, as well as some domestic factories and even private informal workshop imitation accessories, but India has imported genuine parts or specialty packaging plant, posing as genuine parts imported for sale. These accessories are collectively referred to as fake, although you can use, but far less than the original genuine parts quality requirements, particularly in the informal manufacturers of generic parts, from materials, technology, function, and so can not achieve genuine parts and specialty plant products quality requirements for normal use and maintenance of machinery and vehicles are affected, and therefore on the operation and use of units of imported machinery parts identification is essential. Imports of machinery parts can be identified in many ways, mainly from the packaging, the intrinsic quality, price and purchase channels to identify. According to the packaging to identify packaging identification is an important program checks the authenticity of imported parts. Genuine parts and accessories for foreign professional supporting factory packaged beautifully, color, pattern, style has certain rules, in general it is difficult to imitate the same. Rough imitation of packaging production, it was easier to identify. But some imitators rely on modern advanced printing technology, packaging production parts very realistic, if not carefully identify difficult to distinguish. Imports of machinery parts generally have outer and inner packaging, packaging has crates, boxes; packaging and plastic bags or wrapping paper is usually identified with paper bags. Pure imported parts outside the box (box) are posted on the manufacturers unified, clear printing, fine paper, and printed with GENUINEPARTS (pure components) mark, and marked with part number, name, number and manufacturer and country. The generic label printing is not fine, the color is not a light weight, consistent with the pure components is hard packed, non-light colors to use the computer to print the part number and manufacturer marks that heavy, carefully identified, will be able to distinguish the authenticity.
