A hydraulic pump to synchronize the operation of a pair of hydraulic actuators wherein each hydraulic actuator comprises a cylinder including a first fluid port and a second fluid port formed in the proximal and distal end portions thereof respectively and having a piston disposed therein coupled to a piston rod at least partially disposed within the corresponding cylinder. The dual hydraulic pump includes a triple gear assembly to alternately feed pressurized hydraulic fluid to the first fluid port of each hydraulic actuator simultaneously or the second fluid port of each hydraulic actuator simultaneously to synchronize the linear movement of each piston and piston rod in a first direction or a second direction.
A hydraulic gear pump to circulate hydraulic fluid to and from a reservoir and a first hydraulic actuator and a second hydraulic actuator, said hydraulic gear pump comprising a fluid circulation gear box and a manifold together with a housing to house a reversible electric drive motor together with circuitry and logic to control operation of said hydraulic gear pump and to support a control panel to control the operation of said hydraulic gear pump wherein said fluid circulation gear box includes a first gear box fluid flow branch and a second gear box fluid flow branch for the first hydraulic actuator and for the second hydraulic actuator respectively, and a first manifold fluid flow branch and a second manifold fluid flow branch for the first hydraulic actuator and for the second hydraulic actuator respectively wherein said first gear box fluid flow branch of the first hydraulic actuator and said first manifold fluid flow branch of the first hydraulic actuator form a first actuator fluid flow path between the reservoir and the first hydraulic actuator, and said second gear box fluid flow branch of the first hydraulic actuator and said second manifold fluid flow branch of the first hydraulic actuator form a second actuator fluid flow path between the reservoir and the first hydraulic actuator and wherein said first gear box fluid flow branch of the second hydraulic actuator and said first manifold fluid flow branch of the second hydraulic actuator form a first fluid flow path between the reservoir and the second hydraulic actuator and said second gear box fluid flow branch of the second hydraulic actuator and said second manifold fluid flow branch of the second hydraulic actuator form a second fluid flow path between the reservoir and the second hydraulic actuator.
A hydraulic gear pump to circulate hydraulic fluid to and from a reservoir and a first hydraulic actuator and a second hydraulic actuator, said hydraulic gear pump comprising a fluid circulation gear box and a manifold together with a housing to house a reversible electric drive motor together with circuitry and logic to control operation of said hydraulic gear pump and to support a control panel to control the operation of said hydraulic gear pump wherein said manifold comprises a block including a first manifold fluid flow branch, a second manifold fluid flow branch and a valve assembly disposed with a valve chamber for the first hydraulic actuator, and a first manifold fluid flow branch, a second fluid flow branch and a valve assembly disposed within a valve chamber for the second hydraulic actuator such that the direction of fluid flow through said manifold for the first hydraulic actuator and the second hydraulic actuator is controlled by a said corresponding valve assembly, each said valve assembly operable in a first configuration to hydraulically drive or move each hydraulic actuator in a first direction simultaneous;
