A wide range of Electro Hydraulic Thruster that we are offering is precisely designed and developed by adroit professionals at our sophisticated manufacturing unit. Our Electro Hydraulic Thrusters work on a principle of hydraulics. They are easy to mount and dismount. Also, they require low maintenance and power consumption. We are an eminent Electro Hydraulic Thruster Manufacturer and Supplier from Delhi (India). We are backed by a huge distribution network that ensures safe and time delivery of our product.

Working

• On supply of electric power, motor driven centrifugal impeller draws the oil from the low pressure end of the chamber to the high pressure 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.
• Radial blade 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-8 phase sequence.

Features

• Gentle application & release of brake without jerks & shocks
• Compact unit
• Constant magnitude
• Self-aligned movement
• Low power consumption
• Minimum maintenance
• Easy mounting and dismounting

Detail

• Thruster - ST 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.L tank filled with fluid. The piston moves the fluid from low pressure area to high pressure area. The specially designed impeller which is mounted on the motor shaft produces required fluid pressure.
• Thruster - ST 535 To ST 13300 : This range of thruster has 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. The spacer bushes control the thruster. The models are suitable for large capacity, higher motor rating and larger thruster forces.

We are offering a precision-engineered range of AC Solenoid Shoe Brakes. Our heavy-duty AC Solenoid Shoe Brakes are designed and developed using the latest technology and advanced machinery. They are manufactured in conformity with the set industrial norms and standards. We are a renowned AC Solenoid Shoe Brakes Manufacturer and Supplier from Delhi (India). We make them available in various technical grades. Also, we provide customized AC Solenoid Shoe Brakes as per the buyer’s requirements.

Working

• A.C. solenoid shoe brake (A.C. fail safe brakes) is normally in on condition & when A.C.
• Power supply is given to the coil, it will attract the armature.
• The liver fitted with the spring will be actuated and thus the brake opens and allows the prime mover to run freely.
• When power supply is withdrawn, due to spring pressure, the brake shoes go back to their own position and stop the motion.

Specifications

• Drum diameter : 4” (14-21 Nm) / (5.5” (35-50 Nm) & 7” (70-102 Nm)
• Coil voltage : 440 VAC

Applications

• Cranes and Hoists
• Overhead doors
• Machine tools
• Conveyor systems
• Material handling equipment
• Printing machines steel plants & steel rolling mills
• Wire drawing machines

We offer precision-engineered range of Electro Hydraulic Thruster Brakes. These brakes are ideally used to retard the speed of moving machinery. They are fabricated from the best grade raw materials and advanced components. Proper industrial rules and regulations are followed during the production of these brakes. We are a well-established Electro Hydraulic Thruster Brakes Manufacturer and Supplier from Delhi (India). The products delivered are thoroughly tested on various parameters to ensure their quality and durability.

Working

• To stop the moving machinery accurately to the desired position the braking force is applied to the brake shoes by a pre-stressed comprising spring.
• The shoes press on the rotating brake drum retarding its speed and finally stop it.
• The releasing of the bake drum and compressing of the spring is done by thruster.

Features

• Gentle application & release of brake without jerks & shocks
• Compact unit
• Constant magnitude
• Self aligned movement
• Low  power consumption
• Minimum maintenance
• Easy mounting and dismounting

 Assembly & FunctionA thruster shoe brake has a pair of cast iron shoes which are lined up with friction pads. The shoes are hinged on main arm and side arm of the brake, each of them have a hinge pin fitted in the base. They are connected to each other on top by a tie rod, which is hinged in the main arm and locked to the swivel block in the side arm, by a lock nut. A crank lever is hinged on the main arm and the other end is fixed to the top clevis of the thruster by a hinge pin. A brake spring is fixed on the main arm and is pre-loaded by a lock nut on the lever. The pre-tension in this spring decides the braking torque. The thruster is fitted on the base drum by a hinge pin. When the thruster is not energized, the brake shoes are pressed on the brake drum fitted on the drive motor shaft and hold it under the effect of braking force provided by the spring. In such condition, the brake is applied and the drum cannot rotates the piston travels upwards the angle lever turns, pushes the brake rod and compresses the brake spring. Simultaneously, the brake lever on the other side of the wheel (Brake Drum) is retracted. When the first lever reches the stop on the brake base member the brake lever at the thruster begins to move, releasing the brake drum.
