AC Electromagnetic Brakes for any Crane
"ANAND SYSTEM" are the pioneers of the Indian Crane Control gear Industry. With experience in this field for more than 25 years they offer you their most comprehensive range of industrial brakes already being used by various crane and machinery manufacturers.
AC Electromagnetic brake product description
Electro magnetic Brakes are used when a load must be stopped rapidly to prevent the load from rotating due to the motor automatic control whether
it is a question of stopping at a pre-determined time or at selected points of travel or to prevent over travelling.
For fool-proof and safe operation of machinery, modern methods are necessary, which should not tax the operator very greatly.
Any machine which requires its motion to be arrested, whether it is a lifting Crane, Hoist, Winch or Mining Haulage today employs a
Electro Magnetic Brake, enabling the operator not only to arrest the motion but also to hold the load at any desired point without
danger of falling, merely by release of the starting handle.
One cannot possibly mis operate the Brake.
Nothing safer than the Electro Magnetic Brake is available today.Electro Magnetic Brakes also find its use in Paper Mills, Drives of certain
textile machines, Sugar Mill Machinery, Rubber Mixing Mills, Centrifuges and certain hazardous machines, in which a complete stoppage
of machine is necessary before handling of the contents. There is no limit to the use to which the Brake can be put whenever stopping of
the machine is required.
Calculated Size of the AC EM Brake
To calculate the size of "ANAND SYSTEM" Electro magnetic Brake for a given application it is necessary to take into consideration the H.P. Rating
and speed in R.P.M. to obtain the required retarding torque. The basic formula against which calculations are made is :
Torque in Kg.M.
= (71620 x H.P.) / (R.P.M. x 100)
OR
= (975 x KW) / RPM
For minimum size of Electro Magnetic Brake and maximum efficiency the Brake should be mounted directly on the motor shaft.
The application involving ardous duty with more self sustaining load characteristic such as hoist motions of Electric Crane
hoists, skip hoist equipment, overload factor must be taken into consideration.
In applications of this nature it is usual to assess the Brake torque required on the basis of 150% full load torque.
SINGLE PHASE ELECTRO MAGNETIC BRAKE Type:EMB
"ANAND SYSTEM" Electro Magnetic Single Phase A.C Brake
is ruggedly constructed to withstand the effect of mechanical shocks and vibrations.
The brake is manufactured to comply with B.S. Specification.
The A.C. Electro magnet is built of high grade, low magnetic steel laminations each insulated from the
adjacent one.
The entire lot is tightly riveted and machined accurately to eliminate the air gap when the magnet
circuit is closed.
The coils are wound on bakelite bobbin and are thoroughly insulated.
A hand release lever is provided for manual release of the brake. A.C. E.M. Brakes can also be supplied
with Dust Proof Cover
made of sheet steel for only the magnet at extra cost.
The Electro Magnet is secured directly on to the brake lever. The magnet core is made of specially
selected steel having very high permeability.
The coil is varnished with `F' class insulating material and made impervious to moisture.
This brake conforms to IPSS specification
Features of the Electro Hydraulic Thruster Brake:
Normally ON Failsafe Brake
720 Operations / Hour
Possible only because of the well designed thruster & frame
IP rating : IP - 55
Protection against dust and small water jets
Self Contained Unit
Thruster brake provided by Anand needs no external accessories
Provides full constant thrust
Impeller spins at the rpm of the motor and creates a hydraulic pressure on the internal walls of the cylinder
Heavy Rigid Steel Frame
Industry Leading Rigid Steel frame welded for extra strength
Fast Installation
Designed from the ground up for easy maintenance & fast installation
