Shanyi Lehman hydraulic oil hose adopts three-layer steel wire design, high pressure resistance, high temperature resistance, corrosion prevention, specially customized American a standard h-type double sealing joints, to put an end to the oil leakage phenomenon of the oil hose. And the aperture is larger, faster oil speed, greatly improving the efficiency of the work. Other companies in the same industry it is still using the old bend through the line tubing, can not resist high pressure, high temperature, poor sealing, oil leakage and oil seepage phenomenon is obvious and aperture is small, over the oil speed is slow and low efficiency, the mountain a Lehman full range of models speed limiters, the use of flame-retardant, kits, to put an end to the line short-circuiting caused by the vehicle on fire situation. Other companies in the same industry use Vantone speed limit, once the speed limit into the water, short-circuit caused by fire, burning cars abound! After looking at the front frame and then take a look at the back half of the shovel cab using thickened steel soft package design, open vision, driving comfort, debuggable soft package, cloth seats, large travel sub-speed, operating handle, distributor, easy to feel the operation, the use of noise reduction and shock absorption combination of the pad to minimize the driver’s fatigue, feel the […]

Lehman uses steel mountain brand tires, three years of ultra-long warranty, the whole series of models with standard profile steel rings, low pressure wear less, higher stability. Other brands in the same industry use ordinary rubber tires or even retreaded tires, and the quality is not guaranteed. The use of ordinary stamped steel ring, the load is explosive, the tire pressure is easy to collapse, the risk of injury is great, and the tire injury incident occurs every year. Lehman adopts the new speed ratio axle, the torque converter is faster at high speed, more powerful at low speed, and can work in low speed second gear or high speed first gear operation, saving the trouble of switching back and forth high and low speed fast, saving time and labor and fuel saving, highlighting our fuel-efficient design concept, other companies in the same industry still use the old speed ratio axle gearbox, slow speed, small driving force, And can only work at a low speed, time-consuming and costly labor and oil, so that customers are invisible waste, a lot of costs increase the cost of work. Lehman adopts the design of the upper steering cylinder, following the central principle of mechanics, the steering action is more uniform, and in the case of the steering engine is out of control, it […]

Maintenance methods for the hydraulic system of small loaders in daily use: 1、 Before working on a small loader, it is necessary to check whether all fasteners and pipe joints are loose, and whether the pipelines are deformed or damaged. 2、 Before the initial operation of the hydraulic pump of a small loader, the pump should be filled with oil and it is strictly prohibited to run it empty. 3、 When starting the hydraulic pump of a small loader, it should be connected and operated to ensure that it operates smoothly and normally without any abnormal noise before proceeding with work. 4、 If the working pressure of the distribution valve in the hydraulic system of the working device exceeds or falls below the specified value, it should be adjusted in a timely manner. 5、 After stable operation of the system, in addition to constantly observing whether there are abnormalities in oil temperature, pressure, and sound, attention should also be paid to observing the working conditions of hydraulic cylinders, hydraulic motors, directional valves, relief valves, as well as the oil leakage and vibration of the entire system.

The reasons for insufficient oil pressure in small loaders are: 1. The return valve of a small loader is damaged or malfunctioning. If the spring of the return valve of the small loader is fatigued or adjusted improperly, the mating surface between the valve seat and the steel ball is worn or blocked by dirt, and the valve is not closed tightly, the return oil will increase and the oil pressure will decrease. 2. The engine oil temperature of a small loader is too high. If the engine oil is too high, it not only accelerates the aging and deterioration of the oil, but also causes the oil to become too hot, resulting in a decrease in oil pressure. 3. The oil level of the small loader is insufficient, if the oil level is insufficient. It will reduce the pumping oil of the oil pump, resulting in a decrease in oil pressure. 4. Oil leakage from the oil radiator or pipelines of small loaders can cause a decrease in oil pressure. If the pipelines are blocked by dirt, the resistance will increase, leading to a decrease in oil flow and a decrease in oil pressure.

The characteristic of the independent heat dissipation system of the loader is that compared to ordinary heat dissipation systems, timely maintenance is necessary for better use. The change lies in the adoption of an electronic control system for the first time, which ensures that the heat dissipation system is always in the best heat dissipation state. In a heat engine, its thermal efficiency is the highest. Loaders have a wide range of applications. It can also be used to push soil like a plow, or to level the ground, like spreading butter on bread with a knife. The operator can control the loader while driving the tractor. Lehman loader The speed control system of the Lehman loader must be maintained on time in order to be better used. Half a month of regular maintenance and half a month of regular cleaning of the transmission oil pan and transmission oil filter element; Due to the influence of high temperatures in summer, it can bring many difficulties to the use of hydraulic loaders. For example, the heart component of the entire machine, the diesel engine, is prone to wear and tear due to the increase in temperature, which reduces the viscosity and lubrication of the lubricating oil and power. This is a common malfunction. Lehman loader I empathize with the overall coordination […]
