SEM160 fixed axle transmission
With KD (kick-down) function, the gear shifting is smooth and it reduces driver fatigue and improves work efficiency.
High contact ratio gear design, smooth load transfer, low noise and high durability.
4 forward gears and 3 reverse gears, electric control, meeting the requirements for various work conditions.
Manual and fully automatic gear shifting mode provides a more comfortable and convenient driving operation.
Oil filter bypass alert
Gear shifting protection
Auxiliary emergency steering pump connector
Electronic diagnostic tools (SEM EDT) with data logging diagnosis and inspection function.
SEM SI drive axle
Total drive ratio 21.82:1 matches with the load of SEM160 transmission
Fixed front axle, swing rear axle (swing angle ±12°)
Built-in final drive, low noise
The built-in brake system provides efficient brake performance and excellent cooling capacity with small brake force.
The oil-immersed multi-plate disc brake structure enables it to freely adjust the brake fore and effectively avoid contaminant.
Large brake radius, high brake efficiency, and short brake distance.
Large size axle shaft brings the final drive larger torque.
Better performance and durability.
Load Feedback Hydrostatic Drive System
The variable displacement piston pump and motor can provide unilateral track with independent power.
It can quickly realize speed up, reversing and precise steering control, 0-10 km/h stepless speed regulation, as well as power steering and pivot steering function, which improves work efficiency.
Electric Control Speed Regulation Single Lever
Load Sensing Variable Displacement Hydraulic System
Load sensing and pressure compensation
Power and flow distribution according to need and achieve synchronous operation
Built-in lock-up valve reduces leakage at pipe connections and reduces trouble.
World-class Blade Application Range
Electro-hydraulic control traction frame locating pin; control in cab, no tools are required, finished in one minute.
Caterpillar Patented Eccentric Mechanism
Dual frequency and amplitude design
The movable ball offsets the partial weight of the eccentric block and thus low amplitude is achieved.
100% 3D design and 100% JT inspection reduces failures during the design and trial production phase.
First-class structure analysis team and support from Caterpillar experts guarantee reliable structural design and longer service life.
First-class noise analysis team and technical support from Caterpillar noise analysis experts.
Simulation analysis on machine performance, material application, heat treatment and noises, etc.
Caterpillar (Qingzhou) Loader Test Field
As a famous Chinese construction machinery enterprise, CQL has an impeccable loader test field. And CQL is currently the sole enterprise that has a complete machine test field in the industry in China. First-class test team, instruments and test site guarantee product performance and reliability. Other national departments also borrow CQL’s test field to conduct product testing and evaluation.
“8”-shaped runway—used to test the loader performance in the aspects of steering, bumping and flexibility of articulation.
Loop runway—used to test the loader performance in travel, speed up and brake.
Grade-ability test field—used to test the loader traction, grade-ability and brake performance under full load condition. CQL requires that all loaders have the grade-ability of 30% under full load condition.
Bumping test field—used to test the vibration absorption performance and the firmness of the structural parts under full loader conditions.
Breakout force test field— used to test the tipping load of the loader under straight travel and full steering conditions.
Work efficiency and fuel consumption test field— used to test the loader’s work efficiency and fuel consumption under various work conditions.
Noise test field—used to test the noise during loader operation with full load, and keep it in accordance with the national noise standards.
