Crane Brake Dealers in Mumbai

OperationThe braking torque is applied through the action of compression springs that operate the shoes when the current is interrupted. When the current is switched on the shoes is lifted from the drum, the electro-hydraulic thrustor unit acting against the pressure of the springs. The normal position of the brakes is, therefore, 'ON' (shoes gripping the drum), and the brake will return to this position when the current fails. General SpecificationBreak ConstructionThe brakes are robustly made with few and simple working parts, The shoes and base of close grained cast iron and the fulcrum pins are of ground mild steel working in long, reamed bearings. The shoes are fitted with easily renewable woven, fibre, linings held by countersunk rivets, They are adjustable for wear and the pressure exerted by them is easily varid Pivoted shoes are standard on all thrustor-operated brakes. ThrustorsThese are standard electro-hydraulic supplied complete with their first filling of oil. This is 'insulating' oil, Grade 8.30 to British Standard 148, which is readily available at home and overseas. The thrustor cannot be injured by overload or under load. WindingsAll size can be wounded for 3 phase A.C. supplies up to 550 volts and outputs are given here for 50 and 60 C/S supplies. For lower supply frequencies the outputs will be reduced and enquiries should-be referred to us. All thrustors are continuously rated. EnclosuresAll standard units are totally enclosed. Dust seals are fitted as standard, but in extremely dusty situations, or for mounting in the open, a cowl or cover the thrustor is recommended. Cable EntryStandard units have tapped ¾ inch BS conduit thread. Supply leads must be flexible to allow free movement, and cables should have 18 inches free length and be not larger than three-core 7/0.029'' to avoid side drag. Optional Special FeaturesManual ReleaseA level for releasing the brake can be fitted at a small extra cost; this lever is self-resetting. Hydraulic Over-RideHydraulic control, which enables the brake to be applied by the operator by means of a lever or pedal while the thrustor is energized, can be fitted at extra cost. These brakes can be supplied complete with master and brake cylinder, copper pipe and pedal assembly. Brake DrumsBrake drums, or drums combined with rigid or flexible couplings, can be supplied to customers' requirements at extra cost. A stout high duty cast-iron drum will be supplied with the brake, if specified. Drums are machined and keywayed ready for fitting to the motor shaft at cost. Asbestos LiningsAsbestos linings can be fitted to any of the brakes listed in the table. These linings withstand higher temperatures but result in reduced torques, about 0%, because of their lower friction coefficient. They should only used when drum temperatures of over 2200F have to be tolerated and should be the subject of a special enquiry to us. Choosing The Correct BrakeWhen selecting a brake from the rating table, opposite, it is important to consider not only the brake torque but also its duty, i.e. its frequency of application and the duration of each stop. Torque When a large amount of store energy has to be dissipated or when the stopping times is specified, it will be necessary to caculate the torque from inertias and speeds of the moving parts. For many purposes, however the braking torque can be related to the torque being transmitted. The full load torque of a shaft transmitting a known horsepower is given by:Torque (lb-ft.) = hp x 5250 rev/min of shaft.Usually, sufficient will be known about the drive to enable a suitable brake torque to be determined. DutyThe bake must be chosen with consideration of its intended duty to ensure that the linings will not overheat or wear down too quickly. Selection of a brake for torque only would not ensure this. Since the speed of the drum will also affect the rate at which the drum can dissipate the absorbed energy without overheating. The higher the drum speed for a given torque, the higher will be the rate of energy dissipation in the brake linings during each stopping period the rate being expressible as a horsepower. The column headed 'Nominal horsepower based on linings' in the table is intended as a rough guide to the horsepower of the motor for which a brake is suitable when the duty is equivalent to 'normal' crane duty, i.e. not more than 120 operations per hour continuously applied and with a stopping time not exceeding about one second. If the duty of the brake is less than this 'normal' the horsepower given in the table can be increased. If however, the frequency of application is greater or the stopping time is longer, a larger brake may have to be used; asbestos linings can be fitted and a higher drum temperature accepted with a lower torque. Details of brakes with non-standard features may be obtained from us."EMC" THRUSTOR OPERATED BRAKESAC THRUSTOR-OPERATED BRAKES have a wide application; they can be used with such machinery as electrically driven hoists, cranes elevators, ropeways, machine tools, mixers and laundry machinery.

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.

Electro Hydraulic Thrustor Brake is a heavy duty brake designed to withstand the severe duty conditions imposed by heavy duty machinery in various industries. Electro Hydraulic Thrustor transmits useful thrust through the lever onto the brake shoe thereby releasing the brake. When the power is switched OFF, the brake is smoothly applied because the hydraulic thrust acting against the spring pressure is gradually reduced. Electro Hydraulic Thrustor: It consists of a cylinder filled with oil and having a centrifugal pump at the bottom of the cylinder. The centrifugal pump is driven by a 3phase fractional horse power Class ‘B’ insulated, continuously rated rotor and stator. Specially designed radial impeller permits operation of the pump in either direction of rotation. Thrustor conforming to IP-55 & adjustable time lag on both up & down stroke can be supplied at extra price.
