Hoist

CRANOIST wire rope hoist are designed in modular construction, which greatly simplifies repairs & cuts downtime. The special features are low headroom spur / helical gears running on antifriction ball bearings with oil bath lubrication, motors conforming to IS 325, “fail to safe” brakes which automatically operate in case of any power failure, tested wire rope conforming to IS 2266, longed hooks confirming to IS 3815 and push button stations operating at step down voltage of 110v, 24v.
CRANOIST Hoists are designed in accordance with IS 3938 1979.
CRANOIST Hoist are compact, rugged and elegant in appearance to accommodate specific requirements. CRANOIST Hoist can also be built with micro speed, flexible trolleys to negotiate small radius, high speed and high lifts. Hoists suitable for steel mail duty, foundries & chemical plants.
Capacity : 500kgs. To 20000kgs.

Motor

Motors are totally in dust proof construction face / foot mounted TESE / TEFC squirrel cage
Induction motor. B3 construction, 415 V + / - 10% 50 Hz + / - 5%, F class – Insulation, Ambient 50 cent, S4 duty 40% CDF, 150 starts / stop per hour, crane duty motor, Protection Class – IP 55, confirming to IS 325 make – Kirloskar, BBL, Crompton & Siemens.

Brakes

Electro magnetic AC disk type / shoe type, electro hydraulic thruster type brakes are designed and built to arrest and hold safety the full load capacity of the hoists, are provided in all motions. These are automatically released when the motor circuit off. This feature works as a positive safety device as the brakes automatically comes in to operation when the power supply fail.

Gear Box

Gear Box are used in hoist are totally enclosed dust proof construction. The gears and pinions are running in oil bath and hence to external lubrication are required. Pinions are of En. 24 & Gears are of En. 9 forged / rolled steel. Use of totally enclosed gear boxes are desirable in view of the increase transmission efficiency and longer life.

Limit Switches

Limit switched are provided to prevent the over lowering and over hoisting.

Button Block

The hooks is single shank ‘C’ type of forged steel tested as per IS 3815 once to rate table and swivel supported on thrust bearing.

Control Panel

The protective control panel consists of contractors, mcb, relay, transformers etc. The hoist is operated by pendent push button station suspended from the hoist with a wire rope. Hoist are suitable for three phases 415v + - 10%, 50 Hz, AC supply.

Rope Drum

The rope drum is fabricated from seamless pipe / plate having eighter single or double grooved configurations. The rope guide provided for safety of wire rope to prevent our lapping of the rope on the drum.

Optional Features

• Variable speed control / micro speed arrangement through frequency inverts / variable frequency drives.
• Radio remote control.
• Suitable for curvature.
