Selling points

Excellent and stable chassis performance / chassis system

Double-axle drive is used, providing good tafficability and comfortableness under complex road condition with reliable traveling performance. Engine has the multimode power output function, which reduces power consumption. The use of tipping over early-warning technology provides high stability and safety of the overall operation.

Ultra long and super strong boom system
10.6m basic boom, 40.5m full-extended boom and Max. lifting height of 48.5m including jib take the leads in industry in the same tonnage. Rated lifting capacity is 30T, ensuring super strong lifting capacity. Jib mounting angles are 0°, 15°, and 30° which ensure fast and convenient change-over between different operating conditions so as to improve working efficiency of the machine.

Highly efficient, stable, energy-saving and adjustable hydraulic system

Hydraulic system load feedback and constant power control are applied to provide strong lifting capacity and good micromobility. Unique steering buffer design is applied to ensure stable braking operation.

Safe, stable, advanced and intelligent electric control system

The adoption of CAN-bus full-digital network control technology ensures stable control signal, simple harness, and high reliability. Timely feedback of data information can achieve the monitoring of the overall working status in real time. The load moment limiter equipping with the comprehensive intelligent protection system is used with accuracy within 3% to provide a comprehensive logic and interlock control, thus ensuring more safe and reliable operation.

INTRODUCTION

Super structure

Cab:

Value specified in table is rated lifting capacity of the crane under the condition that the crane parks on the flat and solid ground under leveling state;
Values above the thick solid line are determined by the strength of the crane and below the thick solid line are determined by the stability of the crane;
Rated lifting capacity determined by the stability shall comply with ISO 4305;
Rated lifting capacity in the table includes the weights of lifting hook and hanger (main hook: 360 kg; auxiliary hook: 90 kg)
Rated lifting capacity when pulley at boom tip is used can not exceed 3500 kg; after the jib installs, rated lifting capacity of the boom shall be a value that a total is subtracted by the weight of jib (550 kg);
If actual boom length and range are both between two values in the table, the larger value is used to determine the lifting capacity;
