Liugong TC250A crane: high end top grade
The TC250A crane, a new generation of IV emission truck crane developed by Liugong, has first-class lifting performance, excellent driving performance and excellent handling performance. Then let's count the highlights of this device together.
Strong main arm structure
The device is ingenious and meticulous. The five section U shape super strong main arm, the main arm length is 39.5m, the maximum lifting height of the main arm + vice arm can reach 48.2m, the maximum lifting torque 995.5KN.m, which can realize the telescopic, lifting and running of the boom in the operation of the equipment.
At the same time, the product is equipped with anti twisting wire rope. This wire rope has the characteristics of high strength and good flexibility. It can effectively prevent the phenomenon of wire rope winding, and steel wire rope core oil storage can also effectively prevent rust, thereby prolonging the service life.
A sturdy self-made chassis
TC250A uses Liugong self-made chassis, WP7 engine equipped with Weichai / Dong Kang ISC engine to meet China IV emission, combined with Shaanxi Fashite gear 8 with full synchronizer gear box and hand (Germany MAN) drive axle golden combination of power, comprehensive energy saving more than 10%, and the speed is up to 80km/h, climbing is to enhance to 38%, truly energy-efficient. At the same time, the application of TC250A of large displacement gear pump, the domestic first-class master valve and built-in dual pump two-way confluence of technology, make the composite action more smoothly, and can realize the hoist boom, the double combined amplitude, work efficiency increase; bidirectional rotary cushion valve, with free slip function, can realize the pre load condition the ultra low speed precision positioning. Not only that, the product also has a large volume of fuel tank, multistage diesel fine filter and high power hydraulic oil radiator, strong endurance, cold start, automatic fuel heating, users convenient maintenance, and low cost; model with bypass function, Italy imported fan motor group, effectively solve the vehicle under high temperature the problem.
Excellent hydraulic system
Adopting the most advanced hydraulic and electrical control technology and configuration at home, optimizing the speed of boom expansion, hoisting, lifting and so on, make TC250A work efficiency reach the leading level of the industry, adhering to the high construction efficiency of Liugong products. Using modular and universal design, using PRO/E 3D design and ANSYS finite element analysis and other advanced design methods, the structure is more reasonable and reliable. In excess of industry standards, the reliability growth test of driving and operation has been carried out. The new optimization of the turntable structure, the rigidity is greatly improved, and the anti torsional performance is stronger. The oversize leg span of 6.2m x 5.4m ensures the safety and stability of the equipment in the operation. The engine hood is equipped with a gas spring device, which is convenient and convenient to open, and is convenient for observation and maintenance. Weight increase hole design, avoid waste oil pollution weight and frame. The design idea and the Liugong can fully reflect the "people-oriented" but also the number of standard air conditioning, luxurious driver seat and a sliding door, USB music player interface, new rocker switch panoramic cab. The cab is not only open space, wider coverage, soft interior, high-grade, environmental protection, and the main design is also equipped with a folding seat sleeper pneumatic shock absorber, headrest, armrest and seat before and after the height can be adjusted, and has the mechanical damping effect, reduce driver fatigue, spacious and comfortable, practical.
In addition to the above, Liugong TC250A also has outrigger lights, observable mirrors for lifting mechanism, new ladder type low handling force pilot control handle, barrier free fully loaded platform plate, etc., which shows Liu Gong's advanced technology and intentions in crane design.
