Rolex Industries is the manufacturer of Electro Hydraulic Thruster. Rolex Industries manufactures EOT Crane Control Equipments like Thruster Brakes, Resistance Box, Limit Switches, Thrusters, etc.
Electro Hydraulic Thruster is mainly used in material lifting and handling equipment, mainly because their `Fial-to-safety` designs ensure safety to men and machines in the event of over failure. The two main sub-assemblies of the hydraulic thruster, the electric motor and the hydraulic unit are co-axially assembled form the working unit. In the switched off state [de-energised] the piston is at its lowest position due to external load [as brake spring of the drum brake], and the brake is applied. When energized, the electric motor drives the pump and delivers working fluid under the piston axially in the guided path, and delivers thrust or force required to operate the attached devise [like thruster brake] via the piston rod and the eye-lug attached to it. The working stroke can be steplessly controlled by external load. The thruster is designed for long trouble free service. The motor windings are designed to meet contingencies. The bearings are adequately sized.
