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, disc

brake are applied to axle 1 and 2 and drum brake are applied to axle 3 and 4. 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 axle 2,3,4.

Hook (t)

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 included weights of lifting hooks (800kg of main hook 1, 320kg of hook 2 and 140kg of auxiliary hook )

and hangers.

The value listed in the table are applied to 360° working range if no.5 outrigger is fully extended.

Rated lifting capacity with pulley at boom tip shall not exceed 5000kg and then substracts(2300kg)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.

Quality Changes the World
