Used Truck Crane Sany STC75 Second Hand Truck Mobile Crane

Production Details:

Chassis

● Scientific power matching ensures stronger power transmission and more energy-saving power system.

● Adopt mature chassis design and supporting system to make vehicle performance more reliable and maintenance cost lower.

● Adopt super-grade all-steel radial tires, which have stronger bearing capacity and better wear resistance.

● Optional ABS bridge, the braking system is safer and more reliable.

● Adopt 9-speed fully synchronous gearbox, controlled by double h and double flexible shafts, and switch between high and low gears, which makes the gears clearer and the gear shifting easier.

● Adopting hydraulic power steering pump, simple structure, light steering, strong dirt resistance, long life, low cost and easy maintenance.

● It has an international crane road test track, and has passed various enhanced road tests to ensure more reliable driving performance of the chassis.

Operating Cab

● The main boom is made of high-strength steel plate, the basic boom moment reaches 2560.2kn.m, and the lifting performance is strong; the fully optimized U-shaped large arc section main boom makes the boom more evenly stressed, lighter in weight, and improves safety.

● The boom length of the main boom is 45m long, and the two-section 16m variable amplitude jib has higher hoisting and wider hoisting weight range.

● Adopt finite element analysis of main boom design to maximize the strength and rigidity of structural parts, effectively improve stress distribution and improve safety.

● Configure various combined working conditions, including quick extension, arbitrary telescopic extension of two-section boom and half extension of outriggers, which saves time and makes work easier.

● The operating room is made of corrosion-resistant steel plates, and is equipped with humanized designs such as full-coverage softened interiors, panoramic sunroofs, and adjustable seats, making the operation more comfortable and easy.

● By attaching a 2T movable counterweight, the hoisting performance is greatly improved.

Electrical System

● Outrigger automatic control system

The electronically controlled outriggers with automatic leveling and fault diagnosis prompt functions are used for flexible and fast operation, saving time and effort.

● GCP system

The original construction machinery gCP remote information management platform can control the vehicle trajectory and operation status without leaving home, remind the maintenance of accessories in time, effectively prolong the service life of the equipment, and improve the efficiency of equipment management.

● Torque limiter

The highly intelligent torque limiter system is adopted to protect the lifting operation in an all-round way, ensuring more accurate, stable and more comfortable operation.

● Bus meter

The bus instrument integrated with the integrated intelligent control electrical system can control the driving parameters at any time, making driving and riding easier; at the same time, it has an engine fault prompt function, which makes maintenance and troubleshooting more efficient.

Hydraulic system

● Key hydraulic components such as main oil pump, main valve, hoisting motor, and balance valve are all made of high-quality components, and the system has high reliability; through precise parameter matching, the control performance is better.

● Adopt load-sensitive variable plunger pump, which can adjust the displacement of the oil pump in real time, realize high-precision flow control, and greatly reduce energy loss.

● The main valve has the functions of flow compensation and load feedback control, which can easily realize the stable control of single action and combined action under various working conditions.

● The hoist adopts electronically controlled variable motor, and the operating speed is more efficient; among them, the Max. speed of the single rope of the main and auxiliary hoists is 130m/min, and the hoisting efficiency is in the industry.

● Adopting a new swing system, the swing start and braking are more stable, and the fretting performance is more excellent.

● Adopt self-weight drop system to reduce energy consumption and improve the stability of drop operation.
