Hydraulic crawler crane FWT55

FWT-55 is the first national telescopic crawler crane of our self- intellectual property rights, which can be used in some particular situations.

△ High working efficiency, convenient transportation transition

△ The main machine no needs to assemble/disassemble the boom frame, convenient transportation and crawler traveling with the load

△ Main components of power system and hydraulic system are imported from USA, Germany, etc.

△ The easily damaged and consumable s tructural parts are self-made, .and special structure design by us, makes maintenance more convenient.

FWT-55 adopts imported Cummins full electric control engine, and meets Tier 3 standard. The machine has compact structure, and meets the requirements of road transportation. It takes imported torque limiter, adds new functions of boom height limit and left-right slew limit, which make the operation more safe and reliable. The hydraulic parts of the machine are of German Rexroth brand, load sensing control hydraulic system; the main pump is dual variable pump, the main hoist and auxiliary hoist all adopt variable displacement system, which can achieve stepless speed regulation. The cross section of main pump is hexagon shape; this kind of structure has high anti-flex capability. The full closed cab has automatic ascend, descend and pitching function. The ascend and descend height is 1.7m , and the pitching angle is 20o ， which greatly improves the operating visibility.
