Here are some Futures of our Material Handling Equipments:

Frame and Gear Box:
Frame is made out of steel, machined and bolted type.
The gear box is having hardened alloy steel hobbled teeth helical spur gears with solid pinions, rigidly aligned with end load plates. All gears are running on ball/roller bearings with oil bath lubrication and capable of transferring maximum permissible load without noise.

Rope Drum, Wire Rope, Rope guide and Bottom Block:
The rope drum is made from seamless pipe or fabricated from steel plates. The same is grooved to take full lift without over winding. High ratio of drum diameter to rope diameter reduces wear and cable fatigue. The rope drum shaft is made from EN steel and entire assembly rotates on ball bearings, ensuring trouble free operations for years together. Wire rope is of 6 X 37 construction having special plough hemp core flexible steel.

Rope guide is made from cast iron. Fully encircling ring fixed around the grooves of the rope drum to ensure correct rope lay. All our hoists are supplied with rope guide and pressure ring. Bottom block assembly consisting of drop forged steel hook, mounted on thrust ball bearing with large diameter sleeve and hook plates made from steel.

Motors and Brakes:
Foot mounted, High torque squirrel cage induction motors. Specially designed for crane and hoist duty applications. Motors are manufactured as per IS: 325/1996, totally enclosed and having degree of protection IP-54, IP-55.
Brakes are electromagnetic, disc type, spring loaded and suitable for heavy duty application. Brakes are mounted on non-driving end of the motor and they are easily serviceable. Motors and brakes are having class `F insulation.

Control Panel, Push Button Station (Pendent) and Limit Switch:
Each hoist is supplied with a M.S. fabricated, dust proof, metal cabinet control panel. Control panel is equipped with Siemens/L&T/TC make heavy duty, direct on-line sequence reversing airbrake contactors, transformers and fuses.
Push button station suspended by a steel chain or wire rope and all the control cables are brought in to it. Supply to the pendent push button station is either 24 or 110 Volts to avoid electrical shock to the operator. Push button switches are of reputed make and they are of 2, 4 and 6 stations, depending upon applications.
Two limit switches are provided in each hoist to avoid over winding of wire rope and also to control highest and lowest position of load hook.

Trolley:
Cross travel trolley is designed to suit either standard rolled steel joint or box girder. The trolley frame is rigidly bolted with hoist frame through series of holes. This also ensures proper adjustment of flange width. Cross Travel wheels are provided with ball bearings mounted on EN 8 steel axles. The motorized trolley units are supplied with spur gearbox. Hand geared trolley and push pull trolley is also available.

Push Button Station:
P.B. Switches of reputed make are used. P.B. stations are of 2 station,4 station and 6 station as per the application.
