Shandong Lehman Construction Machinery Co., LTD.

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 comfort of the car. Both sides are widened and enlarged fuel tank, hydraulic tank using aluminum alloy, high temperature resistant oil pool and with temperature display clearly visible at a glance. Diesel fuel tank using electronic liquid crystal display, more humanized, to solve the driver off to see the oil trouble. Other products in the same industry use the old soft plastic tube, dipstick easy, aging easy to discolor, and the driver needs to get off to observe the oil shovel, quite a hassle. Shan Yi Lehman will be based on its gas port lead design, but also solved the customer for torque converter oil needs to be disassembled, the cab, the floor of the trouble, for customer maintenance and repair provides great convenience. The corner street large crotch design disperses the articulation force to reduce the stress on the articulation pin to improve the life of the articulation pin, after the frame horizontal alignment design stress dispersion of the whole machine damping force is small, the stability is higher, the whole car structural parts are all finite element analysis, optimization of stress, dispersion of the local weak problem has been solved effectively, to ensure that each car can cope with a variety of harsh working conditions. Other companies in the same industry only part of the structural components to do thickening treatment, completely ignoring the location of the body force, the car has design optimization. According to the frame a fracture, the body is also easy to roll over, vibration force does not get attention, driving is very tired. Hill a Lehman hood using frame-type structure, one-piece stamping space, good heat dissipation, easy maintenance, radiator using double-layer furnace welding design, the water tank increased to eliminate the occurrence of high temperature. Other manufacturers in the same industry use the old hood, small space, poor cooling effect, the engine is easy to high temperature maintenance is very inconvenient.
Counterweight using the upper weight design, greater departure angle, loading and unloading trucks on and off the slope more convenient.
