Wire King Rope Hoists
Armsel electric Wire-Rope Hoists are used in almost every industry, And are known for their enduringqualities and complete reliability, under most exacting conditions.
Upto the minute design, coupled with use of superlative materials and precision manufacturing, combine to produce a hoist with areputation second to none.
Designed and manufactured to comply with requirements of the factory Act and I.S./B.S. specifications. Available in as many as 350 types and sizes for all loads upto 30 tonnes.
Hoists are designed in accordance with is 3938 and relevant India specification requirements, with first ciass materials used in manufacture throughout, The hoist can be electrically operated in all motions or hand operated for trolley motions.
Every Hoist motor is coupled with an Electro magnetic shoe type Brake-Cutler Hammer, or Electro magnetic Disc type Brake EMCO or PETHE make, which act whenever suspending the load at any height. Hoist Brakes are easy to adjust for wear or lining renewal and rated for a minimum capacity of 150% motor running torque to ensure safe holding of the load.
All steel fabricated, machined and bolted type. the gear box is rigidly aligned with the end load plates by substantially holding transfer members which also forms the motor platform for foot mounted motors.
Hoist duty safety low voltage air break contractor type, protective control panel complete with safety self locking fuses, connectors, dust proof sheet metal housing, cable glands, is provided on every Hoist. Low voltage P.V.C. moulded type Push Button Station is suspended from the Hoist by steel support wire for convenient floor operation.
Carbon or alloy steel machine cut, hobbed teeth, helical and spur gears with solid pinions running on ball / roller / needle Bearings with oil bath lubrications. Gears can be examined without dismantling, by just opening the top cover.
Creep Speed attachment can be provided on all models at an extra cost normally giving 1/10th of the main speed. This comprises of an unique differential gear box and auxiliary motor with brake, interposed between the main motor and brake or vvvf duine the only electric Hoist having this type of creep speed drive. The drive is positive and the speed is unaffected by the load. No electrical or mechanical interlocks are required.
6*19 or 6*37 construction special plough steel HEMPCORE flexible steel wire rope having a safety factory of ‘6’ is provided on the Hoist. Galvanised and other constructions of ropes can be provided for special applications.
Over winding is prevented by a hook operated totally enclosed shunt Limit Switch in the Control circuit. An additional rotary switch directly coupled to the drum shaft can also be fitted to provide both up and down limits at a small extra cost.
A series type over-hoisting power limit switch is also available as optional.
Steel fabricated drum, is machine grooved to IS 3938 to accommodate the whole working length of rope in one layer, allowing two dead turns and providing for rope stretch. The drum revolves on amply rated EN-8 shafting on Ball or Roller Bearings.
Drop forged steel ‘c’ type shank hook, with ball thrust bearing mounted on heavy cross head trunion, supported on guarded sheave casing and load plates, designed to IS 3938. Hooks are tested to 100% overload before use. Safe working load indicator plates are provided on the Hook Block.
Normally Squirrel Cage Induction Motors designed and manufactured to IS 325 of reputed make are used in “ARMSEL” Hoists. Only Hoists using fan cooled international frame size totally enclosed 40% CDF high starting torque motors with shaft extension whenever necessary. H.P. and RPM ratings are constantly matched to loads and speeds on all models based on 150 starts per hour.
For more arduous duty like class 3 or 4 operations. Whenever frequent inching is unavoidable, 40% duty or slipring motors can be offered at extra cost.
Trolley wheel load frames are rigidly bolted to series of holes in the end frames, provided with adjustments, to suit standard R.S.J. girder or box Girders. Fine adjustments in 3mm steps is also available on runner wheel axles. Runner wheels on Ball Bearings , are mounted on EN-8 steel axies. Motorized Trolley units have a heat treated Carbon steel spur gear, oil bath lubrication, totally enclosed, trolley gear boxes, coupled with international frame size Electric Motors, Push Trolly and Hand Geared Trolly are also offered. Standard Trollies are intended for straight tracks and special flexible trolley unites are also available to provide for curved track operations. Adjustable bolt suspension rigid trolleys for straight tracks are also standard items.
