The gear couplings are selected based on.

• Horesepower or Torque
• Running RPM
• Physical Space limitations
• Shaft diameter
• Shaft gaps
• Special bore or finish information and type of fit.
• Service factor
• Application or type of equipment to be connected

Based on the application the appropriate service factor needs to be determined.

The maximum degree of misalignment permissible in gear couplings is from 0.5 Degrees to 1.5 Degrees. This varies with the size of the coupling being used.

The Anti-collision Device is a safety device to avoid to collision of two electric overhead traveling cranes working on the same rails.

The System works on the principle of retro-reflective infrared waves. It consists of an emitter and sensor module and a special reflector. The emitter emits the infrared waves in the direction of the reflector. The reflector reflects these infrared waves back to the sensor. The sensor senses the presence of these reflected infrared waves and activities an alarm signal and stops/reduces the speed of the cranes. Thus if the two cranes are away from each other then the reflected waves will not reach the sensor and the cranes operate normally. The sensing distance is adjustable between 3 to 10 meters. The anti collision system is specially designed for the crane application and is suitable for the continuous duty.

Each set consists of an Emitter/sensor module and a Reflector.

For one pair of cranes two sets of anti-collision systems are required

Deadmans control :

This consists of one auxillary contact of two circuit block (1 NO+ 1 NC) operated through a spring loaded push button provided on joystick handle in case of operator looses the grip over button during operation, motion will come to stop as main contactor will be de-energised.

Spring Return arrangenment :

The master / cam controller can be provided with spring return arrangement whereby handle returns to the neutral position when it is released.

Dual Master Controller

Speedage Twin master controller with one universal handle allows a crane operator to operate both bridge and trolley motions with one handle.

The limit switch normally remains closed and cuts off power to stop the motor of the crane. The Lever limit switch operates when it reaches a predetermined position when the lever is moved over a projecting member fixed on the girder. The series limit switch is fitted with four sets of contacts which cuts off two phases of the motor in either direction and is suitable for 500v.a.c. 50 cyclessec. supply system. The limit switch contacts are automatically reset when the lever returns to zero position due to spring action.
