Product Description
Company is mainly engaged in crane design, manufacturing, installation and repair services, re-election. Leading products for the crane 5-50t general bridge crane, gantry crane and 5-50t weight 1-16T electric single beam crane, the company and the process technology joint development and production of QTZ160, QTZ125, QTZ100, QTZ80, QTZ63, QTZ50, QTZ40and other self-elevating tower crane and SC200/200 construction lifting machine, product design, production, installation in strict accordance with the ISO9001 standard, to ensure product safety and reliability. Products can be widely used in large span factory building, warehouse, stadiums, cultural centers, industrial community and other types of engineering.
Company technical materials are complete, advanced technology and equipment, strong technical force, set design, manufacture, installation, commissioning as a whole, with perfect quality assurance system and the detection means, in accordance with the principle of "quality first" and "integrity-based, customer first" purpose, to provide quality assured products for the majority of users.
"Do the industry selection, tree brand, seeking common development" is our eternal pursuit, creating value for customers is our greatest joy, depending on the product quality of life, challenge themselves, to a higher, faster, stronger direction is the goal of our efforts.
Our company adopt mast sections and main chord robot automatic welding system. The system is reliable in performance and high efficiency with high degree of automation. So that one worker can observe several welding systems. The quality and efficiency of welding are greatly improved. In terms of the welding quality of main load structure, the products reach the advanced international standard.
The company also adopts the world first-class automatic spraying assembly line. The large structure pars are dealt with impeller blasting before spraying. That effectively removes steel surface oxides and welding spatters, eliminates the internal stress in welding process, increase the parts' anti-fatigue strength and steel surface hardness, and increases painting adhesion, so that it prolongs the service life of the product, maximizes efficiency, and saves energy.
Plasma cutting machine carries on cutting sheet metal, not only quick cutting speed, but also smooth cutting surface and small thermal deformation.
The crucial parts between the plugs of tower heads, jibs and the matching holes adopt broaching machine processing, improving the hole precision.
Every four masts are grouped and processed together on both end surfaces, so that the flatness of each mast section is guaranteed.
Our company owns advanced manufacturing process due to the introduced and self-developed high-tech manufacturing equipment. Raw materials determine the quality of its products, so that the company directly orders raw materials from famous steel plants in a way of batch purchase to ensure the safety performance or raw materials.
The company choose France's Schneider contactor, and tests each hoisting mechanism under no-load, static load, dynamic load, etc. To ensure the brake reliable, safe and durable.
Brake wheel adopt cast steel materials, surface quenching, external circular grinding and strictly control the beating degree, carry on balance tests, each hoisting mechanism carry on on-load, static load, dynamic load, tec. Test, guarantee the brake reliable, safe, durable.
Derricking mechanism adopt maintenance free Planetary reducer, cone brake motor, reasonable and well-knit in structure, stable and powerful trolley, high endurance.
Slewing motor adopts wound rotor motor, hydraulic, transmission, stable and powerful for slewing
Cabin control devices adopt humanistic design, and ensure comfortable and safe operation.
