Transmission for Demag AC665

The transmission, part number 4130067010, serves as the core power delivery system for the Demag AC665 all-terrain crane. This unit, identified as the ZF Transmatic 16S 220AWSK with the ZF-WSK400-16S 220A transmission number, manages the transfer of engine torque to the drive wheels to enable machine mobility and operational travel. It integrates a torque converter and a 16-speed gearbox to facilitate gear selection and speed control across various load conditions.

This component is manufactured by ZF and is specifically configured for the Demag AC665 series. The transmission system is responsible for converting engine output into controlled mechanical force, which is necessary for the crane to navigate job sites and position itself for lifting operations. Proper integration of this assembly ensures that the machine maintains its intended drive characteristics and maneuverability.

In heavy machinery, the transmission assembly acts as the bridge between the engine and the final drive, allowing the operator to adjust speed and torque output based on terrain and load requirements. By managing gear ratios, the transmission allows the engine to operate within its effective power band, which is critical for the performance of large-scale mobile cranes during transit and site positioning.
