Gearboxes for Port Lifting
XCJ Series Planetary Differential Gearboxes

This product series features a differential planetary structure, characterized by its compact design, high load-bearing capacity, gear modification for larger contact ratios, and low noise. The interior of the gearbox is optimized to transform and decompose the input motions from hoisting motors, opening/closing motors, and traveling motors into different rotational directions and speed combinations for four drums. This controls a series of actions such as the hoisting, opening/closing, and traveling of grabs, making it a key piece of equipment for bridge-type grab ship unloaders.
Modular design, compact structure, short lead time;
Unique gear modification technology for improved meshing performance, providing smoother transmission and lower noise;
Hard tooth surface design meets the high standards of ISO, AGMA, and DIN;
Various lubrication configurations to meet the demands of different operating conditions;
A selection of accessories is available to meet different requirements at a high cost-performance ratio.
Speed ratio range: 11.2–50
Center distance between the two output shafts: 800–2,800 (mm)
Maximum loading and unloading capacity: 5,000 t/h
Bridge-type grab ship unloaders.
