        The advantages and principles of remote control grab

        Release date:2020-05-26

        The advantages of remote control grab:

        1. High efficiency (compared with floor-opening grab)

        2. Stable work (compared with hand-held grab head)

        3. Strong function (compared with hand-pull type and floor-type grab type)

        4. Simple structure and few failures (compared with hand-held and floor-mounted grab heads)

        5. Energy saving (compared with electro-hydraulic gripping)

        6. Safe and reliable (compared with hand-held grab)

        7. Convenient to use (compared with hand-held grab head)

        8. Large-scale (compared with hand-held grab)

        Because of the advantages of the remote control grab, the ship owner's customers prefer to use the remote control grab in addition to the electric hydraulic bulk grab. And because remote control grabs are simpler and easier to manufacture than electric hydraulic bulk grabs, there are several grab companies in China that advertise and produce remote grabs. But it is not an easy task to make the remote control grapple reliable and durable. For example, if a small piece of garbage is in the closed hydraulic system, the valve will be blocked, causing a small failure. , And the remote control grab is to catch small particles of bulk cargo in the boat warehouse.

        Several key points of the residual failure of the remote control grab:

        1. Seal and clean the fuel tank.

        2. Whether the internal structure of the oil cylinder is reasonable. The unreasonable oil cylinder will squeeze the seals and cannot be used.

        3. Whether the system is reasonable, and the unreasonable natural failure is high. Some grapple manufacturers also have accumulators on the remote grapples.

        4. Is the wiring in the electrical connector box simple or complex? There are too many complicated wire ends that cannot be used.

        The principle of remote control grab:

        The grapple comes with a closed hydraulic system. The hydraulic system has a wireless remote control device to control the solenoid valve, and the change of the upper and lower chambers of the cylinder is controlled by the reversal of the solenoid valve. The lower end of the cylinder body is linked to the lower beam of the grapple. The upper end of the piston rod is connected with the grapple sliding seat.

        When the grab is in the open state, to grab the cargo, loosen the grab wire rope, and the piston rod is pressed into the cylinder body under the weight of the sliding block. This is, press the remote control to let the oil tank up and down the oil passage Closed, the sliding seat is locked, the sliding seat and the lower bearing beam are integrated into one, the steel wire rope is lifted, and the grab grabs the goods.

        When the grab is in the closed state, to release the cargo, just press the remote control transmitter, control the solenoid valve to be energized, the hydraulic system oil circuit is opened, the sliding block pulls out the piston rod of the oil cylinder, against the upper bearing beam, the grab opens Release the goods.

        When the remote control grab is used for loading vehicles or funnels, sometimes it is not necessary to open the grab all at once, as long as the grab is opened to the required size, press the remote control transmitter to control the solenoid valve to get electricity , The hydraulic system oil circuit is closed, and the grapple is opened as large as possible. During the process of opening the grab, you can pause at will according to people's wishes.
