Crane Electro-hydraulic Thruster

The crane electro-hydraulic thruster consists of two parts: the drive motor and the body (centrifugal pump). The body part is composed of cover, cylinder, piston, impeller and rotating shaft.

When energized, the motor drives the transmission shaft and the impeller on the rotating shaft to rotate, generating pressure in the piston. Under the influence of this pressure, oil is sucked from the upper part of the piston to the lower part of the piston, forcing the piston and the push rod and beam fixed on it to rise rapidly. The load spring is mechanically compressed by the lever (the pusher or brake has a load spring) to produce mechanical movement.

When the power is off, the impeller stops rotating. The piston quickly descends under the load of the spring force and its own gravity, forcing the oil to flow into the upper part of the piston again. At this time, the lever mechanism is still used to restore the original position.

The electro-hydraulic thruster is often used in conjunction with the brake rack for the braking of various transmission devices.

ED series electro-hydraulic thruster

1. The shell is made of cast aluminum alloy, which is light in weight and beautiful in appearance.

2. The motor is of non-oil-immersed structure, class B or F insulation (according to user requirements). Good heat resistance and long life.

3. The motor junction box cover is sealed, and the cable stuffing box is used to enter the wire, which is firm and reliable. The electrical enclosure protection grade reaches IP55.

4. The surface of the motor shaft and the push rod are plated with hard chrome, which greatly extends the life of the seal.

5. The cylinder housing is equipped with a balance air chamber on one side, which allows the thruster to be installed in any direction from 0-180°, thereby expanding its scope of use.

6. All seals and bearings of Ed series electro-hydraulic thruster adopt world-class products, with reliable sealing and long service life.

7. The fasteners of Ed series electro-hydraulic thruster are made of stainless steel, which is beautiful.
