Product Introduction
This product is the first small-sized crane in the country recognized by the national quality inspection agency The truck crane is more comfortable and safer to drive. This product has passed the national motor vehicle announcement and can be listed in vehicle management offices across the country (big yellow plate) and the purchase fee and other operating procedures are free. The product is light and flexible, low in price, and suitable for rural construction And used in urban-rural fringe areas.
Ton crane lifting machinery configuration
The chassis adopts the Oten` type car-specific lifting chassis engine, Dongfeng gearbox with auxiliary box (with high and low speed weighted Isuzu front and rear axles (vacuum assist Oil brake service brake mechanical steering gear steering.
Wind system main and auxiliary double hook double winch, main winch cycloidal motor crane special ton hydraulic winch auxiliary winch cycloid motor high and low speed hydraulic winch with quick rope release ( Hydraulic mechanical double braking system).
Crane system pentagonal boom (fully automatic hydraulic cylinder telescopic).
Outrigger system fully hydraulic automatic vertical and horizontal cylinder telescopic long-span outriggers.
/> The hydraulic system has a fully hydraulic servo control operating system, and the integrated hydraulic valve group operates independently in a single group (can realize multiple groups of compound actions).
The slewing system has manganese forged tracks, quenched and tempered slewing bearings, and a large four-way central gyrator. (Achievable continuous and unlimited rotation)
The chassis can be expanded and configured, the air brake service braking system can be expanded, the main winch can be expanded, the axial piston motor can be expanded, and the special ton hydraulic winch for small cranes can be expanded. The hoisting system can be expanded to use both oil and electricity. (Electric motor independent pump source, third pump source single cylinder horsepower, load indicator, height limiter.

Product advantages
This product is the first small truck crane in the country approved by the national quality inspection agency, making it more comfortable and safer to drive. This product has passed the National Motor Vehicle Announcement and can be listed in vehicle management offices across the country (big yellow plate) and the purchase fee and other operating procedures are free. The product is light and flexible, low in price, and suitable for use in rural construction and urban-rural fringe areas.
Better performance
The layout of the whole machine is optimized, the stress of the main load-bearing components is more reasonable, and the lifting performance exceeds that of products of the same tonnage in the industry.
Integrated plug-in boom head, embedded arm block, and special telescopic The mature boom technology of the mechanism makes the boom expansion and contraction more stable and highly reliable. The force design is optimized and a new type of outrigger is adopted, which has a larger span, stronger stiffness and better stability.
More control Easy
High-efficiency and energy-saving load-sensitive hydraulic system, sensitive and comfortable operation, precise control, and good micro-movement.
Optimized tie-rod control mechanism makes operation easier.
Small crane control room adopts The large arc front windshield provides a wider field of vision for operation.
Easier maintenance
The newly optimized design of pipeline routing makes the layout more scientific and reasonable, greatly shortening the pipeline disassembly and assembly time and reducing maintenance Cost.
Comprehensively upgrade the electrical system and adopt anti-leakage connectors, which greatly extends the service life of components. The quality is more reliable
Using classic boom telescopic technology, the operation is safer and more reliable.
Carefully build the most complete safety device system in the industry to ensure safer and more reliable lifting operations.
Comprehensive upgraded braking system, dual-circuit air pressure design, and multiple systems ensure all-round braking safety when the vehicle is driving.< br/>The brand-new power steering mechanism adopts hydraulic power-assisted design to make the vehicle steering more lightweight, flexible and precise, ensuring vehicle safety at all times.
The high-rigidity turntable and frame structure are fully coordinated in strength and rigidity.
The perfect integration of design and structural process manufacturing enables complete automation of welding and higher reliability.
