Transmission system

■ Gearbox: Manual gearbox is adopted with 9-gear and large speed ratio range applied,

which meets the requirements of low gradeability speed and traveling at high speed.

■ Transmission shaft: With optimized arrangement of the transmission shaft, the transmission

is stable and reliable. For most optimized transmission, face-tooth coupling transmission

shaft is used with large transmission torque.

Brakes system

■ Air servo brakes are used for all wheels with dual-circuit brake system applied, engine is

equipped with an exhaust brake.

■ Brakes system includes traveling brake, parking brake, emergency brake and auxiliary

brake.

■ Traveling brake: All wheels use the air servo brakes and dual-circuit brake system

■ Parking brake: Force driven by accumulator is applied on the third to fourth axle.

■ For emergency brake, accumulator is used not only for cutting-off brake but also for

emergency brake.

■ Auxiliary brake is exhaust brake with brake safety ensured while travelling downhill.

Values listed in the table refer to rated lifting capacity measured at flat and solid gound under the lever state of the crane.

Value above heavy line shall be determined by strength of the crane and under this line shall be determined by stability of the crane.

Rated load values determined by stability shall comply with ISO 4305.

Rated lifting capacity listed in the table includes weights of lifting hooks (610kg or 555kg of main hook and 90kg of auxiliary hook)and hangers.

Rated lifting capacity with pulley at boom tip shall not exceed 4000kg and then substracts(230kg)to gain rated lifting capacity if the boom is

used to lift after the installation of jib.

If actual boom length and range are between two values specified in the table, larger value will determine the lifting capacity.
