Thruster is an electro hydraulic device, designed to exert acontast force to any mechanism to be operated. The Thruster work on a principle of hydraulics. On supply of eectric power, motor driven centrifugal impeller draws the oil from the low pressure end of the chember to the high oressure upper end. The piston mounted on the same shaft moves to the upper end with full thrust, till its movement is stopped by the stopper shoulder at the end of the stroke. Pressure build up stops when power is discontinued. Radialblade design of the impeller enables it to rotate both in clockwise and anticlockwise direction. Therefore power supply to star connection can be in any R-Y-B phase sequence.

Special Features :

• Packaged self contained unit-No external piping and accessories required.
• Self aligned movement
• Rated force available for the entire stroke
• Compatible for use with any exiting or new system.
• Low power consumption
• Moving parts being immersed in oil, No frictional losses.
• Minimum maintenance.

Thruster Set 520 :A compact 90 watt, 415 volts, 50 cycles, 3 phase Electric motor is directly mounted on the top of a piston. The piston is housed in the C.I. Tank filled with fluid. The piston moves the fluid from low pressure are to high pressure area. The specially designed impeller which is mounted on the motor shaft produces required fluid pressure.

Thruster : ST 535 tost 13300

This range of two thrust rods and a common piston. The motor is mounted on the top cover of the tank. A separator plate divides the tank in two partitions-low pressure side and high pressure side. The spacer bushes control the thruster.

The models are suitable for large capacity, Higher motor ratings and larger thruster forces.

Maintenance :The thruster is designed for long trouble free service and needs no maintenance. The motor bearings are adequately sized and windings are designed to meet the sudden jerks and shocks. Normal maintenance like topping of the oil levels replacement of damaged worn out oil seal and gaskets is required. The terminal box must be cleaned periodically.

Thruster Brake is a device to retard the speed and to hold the moving machinary when it is stationary. The braking force to the shoes is applied through the spring by means of lever/ rod mechanism. The shoes are moved clear of the drum again through lever/ arm linkage mechanism by thruster which over comes spring force.

"MULTITECH SYSTEMS" Offers a complete range of Electro hydraulic thruster for the total range of thruster brakes.

• Base/ Arms : Rigid weided construction with accessible fixing
• Shoes : Self-aligning easily removable high grade cast iron fitted with best quality fabric linings. Large cooling surface drum when brakes are cleared.
• Tie Rod/ Guide Rod : large Section securely fixed in a lug. The tie rod transmits the spring force on the shoes by a simple lever system.
• Springs : Compression springs are vertically mounted through the guide rods are are held securely between guide plates. One are more springs are useddepending upon th brake size and thruster capacity to obtain the desired braking torque.
