The thrustor,Thruster cylinder accommodates a centrifugal pump and a piston with two push-rods extending outside through thrustor/Thruster cover and transmitting effort to the brake   The robust design "Suni" Brand Thrustor/Thruster unit is compact and has long life and is easy to maintain.   Main components used are of high quality cast iron and steel.The"Suni" Make Thrustor/Thruster is operated by an integral three phase squirrel cage motor.    The device has the following advantages: Constant Pressure Gentle Application and release of Brake without jerks and shocks. Larger number of switching-in operations per hour (up to 720).   The rated stroke of each type of thrustor/Thruster can be changed, retaining the same attractive force, by means of sleeves fitted on the rods (inside the body) (this arrangement is possible with models from Suni/ ST 535 and above) In cranes / hoisting machinery, brakes are intended for controlling the speed of load, lowering or for holding the suspended load at rest   "Suni" Make Mill duty Thrustor/Thruster Brakes are suitable for 400/440 Volts, 3 Phase A.C.50 C/S supply for a wide range of drum sizes, from 100mm to 600 mm dia. Higher sizes can also be supplied against specific requirements.   The brake is applied by the tension of the compressed springs mounted vertically between the thrustor /Thruster and brake lever. The thrustor/Thruster rods are connected with the brake by means of an angle lever. As 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. The brake lever at the thrustor/Thruster begins to move when the first lever reaches the stop on the brake base member   The thrustor/Thruster and the brake are so adjusted as to reserve about 1/3 of the stroke for compensation of the wear of the brake linings.

Description Suni Brand Rotary Gear type Limit Switch that is used on Control / Power circuit of reversing drives so as to limit their rotation / movement within a predetermined position. The function of the Limit Switch is to stop the mechanism of drive at the extreme clock wise / anti clock wise position. Suni Brand Rotary Limit Switches are particularly suited for use on reversing drives such as Electric Hoists, Winches, Over Head Cranes, Traversers etc. The contacts of these Limit Switches are rated for 40 amps at 500 Volts A.C. The Limit Switch can be provided with 2NC contacts or (2No + 2NC) contacts as per the requirement. The geared type rotary limit switch basically consists of heavy duty worm gear drive with a ratio of 48:1 The Crane Duty Rotary Geared Limit Switch is made in IP-54 enclosure. in case of IP-54, the cover is of cast Aluminum. Also the Base and cover have machined surface to protect the Limit Switch against dust. The cam shaft which extends from behind the gear into the Aluminium housing accommodates the cams. 2 or 4 cams are used depending upon whether the Rotary Limit Switch is of 2 contacts or 4 contacts operation. The contacts have a maximum continuous Current capacity of 40 amps AC. The contact tips are made of high grade Silver Cadmium Oxide alloy. When used for Series operation [up to 40 Amps maximum], the Contacts are suitable for 720 operations per hour and in case of Shunt operation [ for Control Circuit ] , the Contacts are suitable for 1000 operation per hour.

These switching capacities in fact are far in excess of what is actually required in practice and hence replacement of Contacts for Shunt may not be necessary for a long time. The body of the Contacts is made of high grade Melamine which is specifically suited for heavy duty operation .The material is non – tracking and is capable of with standing heavy arcing.   The Rotary Limit Switch operates in the following manner: The Mechanism or the Drive coupled to the Limit Switch actuates the Contacts through the Worm Gear Drive and the Cams. When the Mechanism or the Drive approaches the pre determined position, the Cam strikes the Contact finger of the corresponding Contact which in normal condition is in a closed position. This immediately opens the Contacts and the Circuit is broken there by disconnecting the respective Motor from the supply and resulting in the stoppage of the Drive or Mechanism. The Actuator or Cam is provided with a maximum follow-through angle of 60 degrees there by ensuring that the normally closed Contact, which has been opened by the Actuator / Cam, shall remain in the open position for at least 8 full additional revolutions of the Input Shaft.   This provision is adequate for most of the Reversing Drives where the Mechanism or Drive comes to a complete stop with in 1/5th of a revolution of the Input Shaft of the limit Switch.   In addition to the adjustment provided for the Actuator/Cam a further fine adjustment knurled Screw is provided for each Contact. This adjustment can be locked in position by locking Screws provided with each Contact fitting.

Suni Makes AC Electromagnetic Brakes that are suitable for AC supply up to 400 to 440 volts, and are available for a wide range of Drum sizes from 100 mm to 380mm Dia. We stand in the midst of prominent Electromagnetic Brakes suppliers based in India.   Since these brakes are in normally closed position, the release of the Brake shoes is affected by energizing the Electro Magnetic coil, which overcomes the spring force and the shoes are moved clear off the drum by lever/arm linkage system so that the drum is free to rotate without any friction.   When the power in given to the Electro Magnetic coil the coil gets energized and in turn pulls the plunger down. The plunger in turn operates the arm of the brakes and the brake opens.   The design of the brake is such that as the lining keeps wearing out due to normal operation of the brake, adjusts itself on its own to achieve the rated toque. When specified, brake drum or drum coupling both pin bush type and flexible geared type can be supplied along with the brakes.

Suni Brand Electro Hydraulic Thrustor / Thruster that is a sturdy Electro Hydraulic device for exerting a smooth controlled upward Thrust on any device with rated capacity from the beginning to the end of the full rated stroke. We are well reckoned as the most preeminent Hydraulic Thrustor/Thruster Manufacturer based in India.   Our Crane Electro-Hydraulic Thrustor / Thruster is provided with Clevis-Lug mounting, allowing them to be mounted up to ten degrees either way from the vertical.   All the Rubber surfaces are immersed in Oil, there by requiring very less maintenance.   One outstanding feature of Suni Brand Thrustor, Thruster is that any Mechanical Overloading cannot cause Overloading of the Electric Motor.   If the Load is greater than what the Thrustor Thruster can lift, the Piston will remain at the bottom of the Cylinder and the impeller will rotate harmlessly in Oil.   In the absence of Load the Piston stops at the end of the stroke and the Impeller rotates in the Oil as mentioned above.   Basically Suni� Brand Electro Hydraulic Thrustor Thruster comprises of a Centrifugal Pump Impeller spinning in Oil there by developing a pressure head. Since there is no outlet, delivery port as in case of a Pump, the pressure developed is impressed on the Piston which is directly coupled to the Load to be lifted. Thus a part of the pressure head is expanded in forming a kinetic head required to lift the Load.   At the end of the Lift, either partial or full i e., when the Thrustor,Thruster stalls, it is the full pressure head which is available. Thus the maximum thrust in the stalled position is always higher than the rated thrust.   The Centrifugal Pump Impeller is driven by an Electric Motor the capacity of which depends upon the capacity of the Thrustor,Thruster .For example in case of a 18 kg Thrustor,Thruster the Motor is of 0.1 HP and in case of 34 kg it is 0.17 HP.   The major components of the Suni Brand Electro Hydraulic Thrustor,Thruster are, a Cast Iron cylinder filled with Transformer Oil, with a Aluminum Piston moving freely in it and a Drive Shaft down the center, through the Piston , to the cylinder.   The Impeller draws Oil from above the Piston forcing the Oil beneath the Piston to give it an upward movement in the cylinder with pressure. The pressure is maintained whether the Piston is in motion or has come to a halt at the end of the intermediate position of the upward stroke.   During transportation the Oil is drained out from the Thrustor hence at the time of commissioning the system required quantity of Oil needs to be filled up in the Thrustor. It is advisable to use only fresh Grade transformer Oil.   The quantity of Transformer Oil required to be filled up in the Thrustor,Thruster depends upon the capacity of the Thrustor. Recommended grade of Transformer Oil is BS 148 or equivalent.
