Hydraulic or hydrostatic transmission (HST) is a key element of the hydraulic system that provides power transmission using a working fluid. It consists of a hydraulic pump and a hydraulic motor that work in tandem, creating a smooth transmission of torque. Hydrostatics are used in special equipment, tractors, combines, excavators, loaders and road construction machines.
LLC "Hydraulic Line" (Kyiv) offers professional repair of hydrostatics of any complexity - quickly, efficiently and with a guarantee.
What is included in the concept of hydrostatics
Hydrostatics is a unit that combines a high-pressure hydraulic pump and a hydraulic motor that converts fluid energy into mechanical movement. The system allows you to achieve smooth speed control, energy efficiency and reduce the load on the engine of the equipment.
But even the most reliable mechanisms eventually require repair or preventive maintenance due to natural wear or leakage.
