HOIST

A hoist is an ideal and most sought solution for installing heavy and massive goods/ commodities. A hoist trolley makes it easier to transport goods and commodities vertically, whether it is an industry, show-room, etc. Are you looking for a customized and high-quality hoist crane, then we at Rachna Elevators & Cranes are here to assist you? We offer high-quality crane hoists that meet the industry standards and the client’s requirements.

 

Hoist for crane are machines that make it easy to lift and transport objects that are practically too heavy to carry manually. Using a hoist crane, it becomes easier to move the materials to another location. The mechanism includes a hoist moist that helps lift the wheel or a drum wrapped to a chain or a rope around it.

What is the Mechanism of a Hoist?

 

A hoist can be defined as equipment that is used for reducing the load. The hoist lifting equipment works through a lift wheel or a drum wrapped by rope or chain. Herein it can be operated pneumatically or else electrically. Besides, the hoist and crane can also use a fiber, chain, or wire rope as a source of lifting.

 

What are the different types of hoist cranes?

 

Hoist cranes are available in different types. It tends to differ based on the need. One of the variants is used in the construction of large buildings. It is known by different names like buck hoist cranes, man-lift cranes. However, they all are the same machines. Besides, the hoist lifting speed also tends to differ as per the size of the hoist lifting equipment chosen.

What are the features of the hoist cranes?

  • It comprises one or two cages that travel up and down through a tower of stacked sections.
  •          Every section for the hoist is approximately 25 feet. Besides, they must be added at regular intervals to ensure there is enough stability.
  •        The auto hoist allows the system rack and pinion motorization, wherein you can use the cage to move based on the hoist lifting speed.

 

What are Crane Hoists used for?


Hoist cranes are popularly used for underground mines. It can be operated either manually, by water or through animal power. They are used to lift and lower the conveyances into the shaft. However, at present, the hoist for crane is powered through electricity.

 

What are the different types of hoist cranes?


We at Rachna Elevators & Cranes are pioneers in offering the best quality and finely designed hoist cranes. The cranes can be used for various operations. It includes friction hoists, multi-rope cranes, and drum hoists.

 

How are the crane hoists used?


Hoist cranes are used either used with a chain or a rope. Hoist using chains have a lever that actuates it. Besides, the handheld model that is known as a ratchet lever hoist is operated manually. The biggest benefit of using this type of hoist is it can be used for orientation, whether for lifting, binding, or pulling. Thus, when opting for either rope or a chain hoist, it is necessary that the rope is lighter but is limited by drum diameter. On the other hand, chains are comparatively large and heavy.

RIGID INSPECTION
Stern inspection procedures at all stages of manufacture ensure unfailing dependability.
DESIGNHoists are designed for all classes of application as per IS-3938. Standard Design is for Class II.
MODULAR CONSTRUCTIONHoist is assembled from different independent units viz. Hoisting Gear Box, Hoisting Motor with brake, Rope Drum, Electric Control Panel and Travelling Trolley. All these units are separately accessible and promptly disassembled to simplify repairs, reduce maintenance cost and downtime.
MAIN FRAMEM.S. Plates are fastened with number studs to withstand the load of the different independent units attached to it.
WIRE ROPEHoisting rope comply with the Indian standards Is:2266. The factor of safety, on the nominal breaking strength of the rope is six.
ROPE DRUMGrooved Drum, Seamless Pipe of adequate length to be wounded in one/two layer and to provide proper support for the rope to minimise abrasive wear is provided. Drum Shaft revolves on self aligned roller Bearings for ensuring smooth running.
ROPE GUIDERope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may not uncoil even when the Hoist is in unloaded condition.
MOTORMotor are of Squirrel Cage, 40% CDF rating in class B insulation as per IS-325-1970, The unit is an IP 54 dust and damp proof enclosure, flange-mounted to the main frame of the Hoist. When creep speeds are required same is achieved by way of DC Clutch manufactered by NGEF/ Bharat BIJLEE/ GEC/ CROMTON/ own make. Hoist Motor is an HTSC parallel rotor machine. Specially rated for Hoist
GEAR BOXHoist Gear Box has specially treated gears for high wear resistance. Each Geared Shaft assembly is supported on bailor roller bearings, to ensure smooth, low-friction operation, the gear trains are greese lubricated. Also oil immersed Gear Box can be provided on request.
BRAKEElectromagnetic Fail-safe type brake mounted externally on the rear end of the Hoisting Motor ensuring easily accessibility.
HOOK BLOCKThe Hook Block is tested to 150% of full load before assembly. The rope sheaves are fully guarded with protective steel castings. All sheaves rotate on Ball Bearings.
TROLLEYIt consists of M.S. Plates forming side frame assembled with Runner-Wheels. Runner Wheels are mounted on Double sealed Ball Bearings. Trolley is adjustable for various I Beam sizes
LIMIT SWITCHESA Limite Switch is built in as one of many safety features preventing accidental over-hoisting and over lowering of the hook block. The trip positions are adjustable to allow correct setting for installation.
ELECTRIC CONTROL
PANEL
Controls are mechanically and electrically interlocked to prevent inadvertent operation of opposite motions and are all housed in an IP 54 dust and damp proof enclosure. A low voltage control system of 110 Volts. Minimises electrical hazards for the operator.
