Leading bridge with a load capacity of 15 tons
1.In the main transmission, cycloidal bevel gears with equal tooth heights are used, which are distinguished by high strength, high transmission efficiency, and low noise level.
2.On the wheel side, a planetary gear mechanism of the NGW type is used with a reasonable and compact design.
3.The hydraulic steering assist provides flexibility in control.
4.The bridge body is made of cast iron with spherical graphite, has good rigidity and high load-bearing capacity.
5.The brake uses a closed multi-disc wet brake with hydraulic pressure and spring release, ensuring stable braking, high safety, and reliability.
6. Suitable for a 15-ton wheeled excavator.
MAIN CHARACTERISTICS:
This leading steering bridge is the main transmission device designed for 13-16 ton wheeled excavators.It has a two-stage reduction gear design, a hydraulic steering system with an amplifier, a closed multi-disc brake with wet coating, and combines three main functions: steering, movement, and braking.Its main function is to transmit power from the transmission to the wheels and convert it into driving force, as well as ensuring steering flexibility and reliable braking during equipment operation, which fully meets the requirements for heavy-duty conditions and high mobility of construction machinery in complex working environments.
