Truck crane STC250H

Chassis
Scientific power match, ensuring a more robust power transmission and power systems more energy efficient.
9-speed gearbox and gears more clearly, shift more portable.
Hydraulic power steering systems, simple structure, steering.
Using sophisticated chassis design and matching system, making the vehicle more reliable and lower maintenance costs.
Full width cab and ergonomically designed to make driving more comfortable.
Has the international advanced road test of crane runway, through various types of intensive road test, driving performance ensure the chassis is more reliable.
Optional ABS axle, braking systems safer and more reliable.

The bus
Main arm made of high strength steel plate, basic arm torque up to 980kN.m, the longest arm torque 470kN.m, lifting ability, fully optimize the u-section main boom, boom force more evenly, better rigidity, higher security.
Main boom jib length industry first, full arm length 39.5M, lifted higher, lifting broader.
Finite element analysis of main boom design, optimal strength and stiffness, improved stress distribution and improve security.
Secondary arm arbitrary scaling conditions, operate more efficiently, more relaxed.
Transverse span Outrigger industry first, superior lifting performance.
Operating room made of corrosion-resistant steel sheet, configure the full coverage soft interiors, panoramic sunroof, adjustable seat and other user-friendly design, operating more comfortable and relaxing.

Electrical system
GCP systems
Original GCP remote management platform of construction machinery, patrons take control of vehicle trajectory operations, remind accessories maintenance, extend equipment life, and improve the efficiency of equipment management.
Bus instruments
With integrated intelligent control the bus electrical system instrument, may at any time take control of line-drive parameter, driving more easily and has an engine malfunction prompts, troubleshooting maintenance more efficient.
Load moment limiter
Highly intelligent Torque limiter system, all-round protection hanging load operations, ensuring more accurate, more stable, more comfortable operation.

Hydraulic system
Main oil pump, main key hydraulic components such as valves, balancing valve, using high-quality components, high reliability through exact parameter match, control and superior performance.
Applying load-sensing variable displacement piston pump, real-time control pump displacement, high precision flow control, greatly reducing energy consumption.
Main valve with flow compensation, load-feedback control function, in a variety of conditions, easy to realize stable control of individual and combined movements.
Winch with variable piston motor, can achieve low speed and high load at low speed switching operations more efficient.
New slewing system, turning more smooth starting and braking, fretting more outstanding.
Gravity falls picture system, reduce energy consumption, raising the flag fall picture smoothness of operation.
