A quality service rigorous, improved process, excellent after sales service, optimal and realistic management
Our company has always attached great importance to the quality of our products, our LHD has been tested by the national inspection center and all the results have reached or exceeded the national requirement. We have obtained the national mine safety certification and ISO9000 quality management system certification We are in the forefront of this kind of products and we strictly checks the quality of each step of the process, we strive to make the best products.
LHD's scraper parts have immediate impact on the efficiency and service life, our company naturally has its own machining workshop, equipped with variety of modern equipment, our part for our vehicle can be turning, milling, planing, polishing, drilling, etc., guarantee an accuracy machining of each parts.
The frame is an important part of our scraper, it affects directly the whole machine quality. To improve the quality of the frame, we have adopted 16 manganese steel, it's a low alloy steel with good welding property. After cut, the steel is weld in accordance with standard welding process. After welding, the frame is cleaned, before a 24 hours annealing treatment to eliminate internal stress. After this, blast treatment remove oxidation from the surface, then, we apply a spray primer to have reliable rack.
For external parts, our company selects its from well-known international companies, easy to confirm, for example, our LHD two cubic meter, uses a German low pollution air cooled engine from DEUTZ with double combustion stage, and catalytic exhaust silencer from Canada. The transmission system uses DANA's torque converter and power shift gearbox, pumps and valves are from PARKER.
This component quality is a good security about the viability and longevity, our workers are also qualify and have large experience, following all innovation to always be at the top, we strictly respect all the assembly process and and every step is controlled to avoid any problem, each machine is adjust and completely validate in our testing area. Giving us the confidence that all function are optimal for our customer before the cleaning and final painting.
