Fixed mounting type of hoists can be provided with any type of mounting
      positions as shown
They are used for loading and unloading transportation vehicles, through
      floor hatches or outsides the wall, and they can be used for any pulling or
      lifting applications
While ordering, pl. inform the combination of mounting position of the hoist
       and wire outlet (wo) required.

Hoist can be mounted on trolley for horizontal travelling.
The trolley is fabricated from components bolted and welded together and moves by travelling wheels       supported on ball bearing.
Smaller loads can be moved with a push type trolley whilst the hand chain
      or motor driven trolley should be used for heavier loads
The motor driven trolley would be the best solution if the hoist unit is required to move loads rapidly and move       frequently.
The drive motor is of squirrel cage type with built - in conical disc type
      electromagnetic brake. The motor drives two or more of the trolley wheel's.
 Wherever there is limitation to the available head room ( dimension H ), short
      head room trolley can be supplied (refer figure 6 above).
The standard cross travel speed of motor driven trolley is 12 to 14 mtrs/min.
      Higher or lower speeds can be provided if required
Please furnish height [h] and flange width [w] of the beam on which the hoist
      is to be mounted, while ordering.

 CONVENTIONAL HOISTS - Having standard cylindrical rotor motors
      Conventional Hoists, called such as they are provided with motors having
      conventional cylindrical rotors. These hoists therefore need to be provided
      with a separate and dependable electro magnetic brake.
      The operational requirement for hoisting / lowering and stopping of hoist is
      such that when the hoist's motor is put ON, the coil of the brake must energize instantaneously to operate       and release the brake holding the rotor
      shaft, to enable the motor to run and operate the hoist. Similarly, when the
      hoist motor is put OFF, the brake coil must get de-energised instantaneously and operate, so that the brake       holds the rotor shaft and stops the motion of
      Hoist. Hence a perfect and foolproof synchronization between the motor's
      winding and the brake's coils winding is must and an absolute necessity.
      Experience has shown that this required perfect synchronization between
      the windings of motor and brakes coil gets disturbed over a period of usage and time, and thus the time iag       between the starting of motor and actuation
      of brake results into excessive current taken and thereby heating up of motors winding due to its over       heating up of motors windings since the brake does not immediately release the rotor shaft. While the non       release  of rotor shaft when the motor is put ON can lead to burning of motor winding due to its over heating       over a period of time, the non actuation of brake as soon as the motor is put OFF could lead to non stoppage       and unwanted traval of hooks movement which could be a more serious matter.
      Burning of motor windings could lead to down time and loss of production and the unwanted travel of hook       could lead to damages / accidents.It is
      therefore that there has always been aneed to have hoist motor with built-in
      braking arrangment so that the motor itself actuates and deactuates the
      brake. Motors having their stators and rotors made in tapered or conical form
      eliminate the need to have a separate winding for braking action.
      The conical rotor motor itself actuates and de-actuates the brake instantaneously as has been explained as       under.

 RAHAT Hoists - Having Conical Rotor Motors
      The very need of developing a conical rotor motor was to eliminate the need
      to have a separate electromagnetic brake for brake actuation of hoists.
      The RAHAT make conical rotor motor itself actuates & de-actuates the brake,
      as explained here under. Refer the above skech.
      RAHAT HOIST Conical rotor brake motor is a combination of an electric motor & a conical disc constrction,       mechanical type of brake, operating on sliding rotor principal. The unique characteristics of the motor is due to       conical shaped rotor and tapered stator bore.
      The rotor is mounted on the rotor shaft which is supported on roller bearings. This rotor shaft carries rotor       pinion at on end to impart drive to the
      rope drum through the gears trains & a conical shaped brake disc on other end on which a heavy duty       moulded type brake lining is mounted. At rest the
      motor is in braked condition.
      The Electromagnetic field produced, when the motor switched ON, creates
      a vertical as well as a horizontal force due to the conically shaped air gap.
      While the vertical force produces the torque for running of motor as in case of any other normal motor, the       horizonal force overcome the force of brake spring and the slides the rotor axially towards the minor diameter       of rotor regardless of direction of rotation of motor.
      The axial sliding of rotor is arrested & limited by the thrust bearing to maintain the proper air gap between the       running motor and stator bore.
      This axial displacement of rotor releases the brake & allows the motor run to like any other standard motor.
      When the motor is put OFF or incase of power failure the Electromagnetic fild collapses hence the axial force of       motor disappears & the brake spring slides the rotor back to its position, forcing the brake disc with brake       lining against the braking surface & thus enabling a fail-safe & fool-proof braking of hoist.
