Qingdao Kerite Laser Equipment Co., Ltd.

Based on mature hydraulic bridge technology, the company has launched a hydraulic rear-drive steering axle suitable for four-wheel drive. The product uses a radial plunger motor to directly drive the tires without an intermediate transmission system. With the help of mature and reliable hydraulic components, the drive is more reliable. The wheelbase can be customized according to user requirements, using double-acting steering cylinders. With the hydraulic bridge, it can provide stronger driving ability, adapt to the complex road surface of farmland, and provide a more reliable guarantee for the whole vehicle to travel.

Based on the mature technology of the 1000 and 800 series of hydraulic bridges, the company has launched a 600B hydraulic bridge suitable for harvesters with a full load of about 6-8 tons. This product not only inherits all the advantages of the original hydraulic bridge, but also improves the design of the gearbox. With the advantages of compact structure and strong load capacity, the reliability is greatly improved.

Since the company put forward the idea of grafting construction machinery hydraulic drive and electronic control technology to agricultural machinery in 2010, it took three years, through continuous design improvement and verification, and finally successfully launched in 2012 suitable for wheat harvesters and small corn harvesters. The 800 series hydraulic drive axle of the large grain combine harvester such as the machine and silage machine. This bridge makes the manipulator easy to operate and greatly improves the comfort of the operation. At the same time, the clutch with high failure rate of the original mechanical shift bridge is eliminated from the design. And the stepless torque-increasing device greatly improves the reliability of the whole machine. Tests have proved that the harvesting efficiency of the whole machine is increased by more than 30%.
