Hydromechanical transmission, four-wheel drive offer larger driving force and breakout force: Light and flexible small turning radius is particularly suitable for limited field. Z-type bucket stick system, single rocker, horizontal hoist tank of high supporting point, powerful breakout force and shorter working circulation time provide higher working efficiency. All hydraulic load sensing steering that supplies oil on demand preferentially and valve working hydraulic system of single pump priority are economic and energy-saving.
