Abstract

An immobilization device acting on the hydraulic system of plant machinery such as earth moving machinery comprises a 3 way 2 position spool valve operated by a solenoid. The valve diverts the fluid flow on the pilot side of the system directly back to an hydraulic oil tank to render the machine inoperable. The device is operated by remote control.

Description

DESCRIPTION
A device for immobilizing the hydraulics on plant machinery using the pilot side of the hydraulics to immobilize the machine, and also using an electron remote to operate the system using a 3 way 2 position spool typ solenoid valve that would be opperated via a remote.
See drawing.

Claims (3)

  1. An immobilization unit operated via a remote control for earth moving machinery and plant.
  2. 2 Remotely immobilizing the hydraulics on earth moving machinery and plant via the pilot pressure side of the hydraulics.
  3. 3 Interupting the pilot pressure using a solenoid valve which can be operated Remotely to allow the flow of oil to be diverted directly back to tank thus stopping the pilot pressure from working and hence dissableing the machine
