Hydraulic force (either in pull or push mode) is applied on the rail by means of two numbers double acting cylinders operated by a hand pump fitted with direction control valve, oil distributor and pressure gauge. cylinder is connected to hand pump by means of high pressure rubber hoses and quick connect - disconnect couplers.The hydraulic rail tensor is disposed so as to hold both rail ends before and during the welding maintaining the prescribed gap and the prescribed stress in rail. It is also used for broken rail repair of C.W.R. The main components are: A hydraulic hand pump or electric hydraulic pump, two double acting rams, two holding devices, two rod, high pressure hoses with quick coupling fittings.
