QUY100A hydraulic crawler crane is designed on the basis of advanced technology and special manufacturing experience. It has the characteristics of self-assembly, large chassis, low gravity center, excellent stability, beautiful appearance and comfortable operation.

Features：
1. Lower frame is connected with side frames through drive pins and fixed pins. The drive pins are driven by hydraulic cylinders for the convenience of assembly and disassembly.
2. X-type box construction for lower frame with the features of beautiful appearance, rotating-resistant.
3. Independent hydraulic propel drive is built into each crawler side frame. Each drive consists of a hydraulic motor propelling a drive sprocket through a planetary reduction gear. Hydraulic motor and gear box from Teijin in Japan are built into the crawler side frame within the shoe width.
4 .Half-opened platforms are convenient for inspection and maintenance.
5．Parallel grooved drums offered for hoisting system are driven by the variable displacement motor through the planetary reduction gears. The drums are connected with the platform through the pins.
6. The engine from Cummins is with the characteristics of space-saving and high power. The suction pump is mounted on the fuel tank for the convenience of filling the fuel.
7．Open loop hydraulic system with the features of independent cooling, combined sensing, smooth movement, good performance of fine speed and easy to operate.
8. Closed loop slewing system, Control valve for slewing pump from Rexroth directly controls the flow, which offers smooth movement and good performance of fine speed.
9. The machine is equipped with safety warning devices and fault-diagnosis device.
10．The control system based on CAN-bus technology (J1939 Agreement) offers efficient control for all functions. All parameters are displayed on the load moment limiter.
11．The operator and the signaler are all equipped with interphones for the convenience of communication.
