Gkaf Hoisto Cranes Sidhapudur, Coimbatore, Tamil Nadu

The next option is the under-slung crane, which runs on the bottom flanges of rolled steel beams which form the crane tracks. These are usually indoor cranes and the crane tracks are suspended from the building structure. They have the advantage of being able to cover part of the building span without obstructing the floor below. Latest in this type are light weight crane systems wherein hollow sections are used as track sections inside which the travel trolley wheels move. These track sections can be used for the long travel tracks and also for the crane bridge.The under-slung arrangement allows the bridge of this type of crane to be designed with a cantilever at one or both ends.

Transfer cars are designed basically as per clients’ requirement and to meet necessity of industries.The frame is made from fabricated steel plates / rolled steel sections of ample strength.Travel motion wheels are provided as per the application.

GKAF hoisto cranes brand Electrically Operated Overhead Travelling Cranes are designed & manufactured in accordance with IS: 3177 and IS: 4137. The structural parts of the cranes are designed in as per with IS: 807 and IS: 800. Our cranes are manufactured with standard components and controls to ensure reliability.The single girder design, in general preferred up to 15T capacity and span of 20M, is made from either rolled steel I-beam with C-Channel capping section on top for lateral stiffness or box section fabricated from plate. The rolled steel section girders, even though widely used, are ultimately limited by the availability of beam size and length. The distance from the hook at the top most position to the top of the gantry is often greater than indouble girder designs, although low headroom hoists can minimize this limitation.     STANDARD FEATURES:  GKAF hoisto cranes cranes have high quality structural assembly.  GKAF hoisto cranes cranes have minimum maintenance.  Easily adjustable imported brand limit-switches.  Load tested to 125% and certified by GKAF hoisto cranes from tests undertaken in our own workshops.   RANGE OF SPECIFICATIONS:  Safe Working Load: 500 kgs to 50,000 kgs  Span: 30 mtrs  Height of Lift: As per customer specifications  Class of Duty / Standards: M5 to M8 as per IS 3177 / IS 807  Speeds: As per clients’ specification / application.  Crane Control: From floor through Pendant Push Buttons, Optionally through Radio Remote Control / cabin with master control  Drive System: Twin Drive through Squirrel Cage Induction Geared Motors with built-in fail safe brakes  Motors: Squirrel Cage Induction Crane duty motors, IP 55 enclosure, S4 duty, 40% CDF  Brakes: ACEM / DCEM disc type brakes, optionally Shoe type brakes for hoist & LT motion  Power Supply System: To Hoist and Cross Travel through C-Rail Cable system / Cable Drag Chain To Crane through Shrouded Bus Bars / Trailing Cable / MS Angle Iron Conductors / Bare Copper Conductors (depending on customer's choice and application)

A goliath (gantry) crane is similar to a top running crane except that the crane bridge is supported by legs and the rails are at ground level. The additional leg structure makes the crane more expensive, this is offset by the considerably cheaper low level rails. That advantage increases with increased track length making them particularly suitable for large outdoor stockyards. There is an additional safety hazard arising from travelling on low level rails which must be considered, but this can usually be taken care of easily and ground level rails can be advantageous compared to the obstruction caused by the building structure columns. They can be of single or double girder design with similar construction methods. Furthermore they can be designed with a cantilever at one or both ends.A semi-goliath (semi-gantry) crane is a hybrid of a goliath and a top running crane with one end of the bridge supported by a high level gantry and the other by a leg running on a low level track. Typically they are used in an area adjoining a building and the high level gantry is integral with the building structure. They are therefore suitable for outdoor stockyards alongside a building but also for indoor use where a full span of the building is not required.Outdoor duty goliath cranes are checked for stability under storm condition. Special storm anchors are provided to prevent toppling of crane under storm condition.     RANGE OF SPECIFICATIONS:  Safe Working Load: 500 kgs to 50,000 kgs  Span: 20 mtrs  Height of Lift: As per customer specifications  Class of Duty / Standards: M5 to M8 as per IS 3177 / IS 807  Speeds: As per clients� specification / application.  Crane Control: From floor through Pendant Push Buttons, Optionally through Radio Remote Control / cabin with master control  Drive System: Twin Drive through Squirrel Cage Induction Geared Motors with built-in fail safe brakes  Motors: Squirrel Cage Induction / Slipring Crane duty motors, IP 55 enclosure, S4 duty, 40% CDF  Brakes: ACEM / DCEM disc type brakes, Shoe type brakes for Hoist, CT & LT motion  Power Supply System: To Hoist and Cross Travel through C-Rail Cable system / Cable Drag Chain To Crane through Shrouded Bus Bars / Trailing Cable / MS Angle Iron Conductors / Bare Copper Conductors (depending on customer's choice and application)

GKAF hoisto cranes make electrically overhead traveling cranes are designed & manufactured in accordance with IS: 3177 and IS :4137. The structural parts of the cranes are designed in as per with IS: 807 and IS: 800. Our cranes are manufactured with standard components and controls to ensure reliability.Double girder crane designs can use the same rolled steel sections within the limits imposed by available sizes. For higher capacities and longer spans, box girders are the usual choice.
