Goliath / Gantry Crane which most ideal Material handling equipments to handle heavy loads in Open Yards or indoor where don’t required columns for gentry. It is generally used for Outdoor application same time form place in Indoor Application also.It runs over floor on rail. Generally these Cranes are used at

• Ship Yards / container depo
• Granite & Marble cutting and polishing Industries
• Steel yard
• Cemet Pipe Industries

All cranes are basically fabricated out of standard rolled Steel sections and plates by using adequate size to suit the requirement. The entire structure can be divided into three main parts. Main Bridge, End carriages and Crab. In case of Gantry/GOLIATH Cranes the Bridge Girders are fixed on the top of four gantry Legs which are connected to two under carriages. The salient features of above three parts are as under.

MAIN BRIDGE The main bridge Girders are fabricated from high quality steel plates forming a rectangular box section. The girders are provided with the required camber so that the Girder deflection in full load condition will remain well within its allowable limit of 1/900. Internal surface of the box girder is free from corrosion as the box is welded and there is not contact with outside atmosphere.

Maintenance - It is easy to carry out maintenance of the crane and clean it. Here provide hand railing platform for easy maintanace in one side or both side as costumer requirment

CRABThe crab is manufactured from M.S. Plates and rolled steel sections. which is also provided with cross traverse wheel running on L-block type bearing housing assembly similar to that of L.T. wheel assembly. For heavy duty application, entire crab is fabricated out of M.S. Plate. The crab is carrying hoisting and cross Traverse unit with necessary brake assembly. Salient features of these are as under.

GEAR BOXAll the gear boxes which are used in Hoisting, L.T. and C.T. are horizontal shaft helical gear type with robust and sturdy M.S. fabricated housing. The entire gear assembly is running on anti friction bearing. The pinions which are used in the gearbox are integral and solid one piece pinion. All gears and pinions are duly hardened to with-stand the heavy loads for the life span depending upon the class of application. Provision is kept for the filling the lubricating oil with level indicator.

ROPE DRUMRope drum is fabricated out of M.S. plate or made out of seamless pipe. The drum is accurately machined and grooved to accommodate the desired size of rope. The length of the drum is selected in such a way that the entire rope can be wound in one layer.

LONG TRAVEL For long travel arrangement following methods are used.

Center Drive Arrangement. In this system of long travel arrangement, long travel motion is availed through centrally located helical Gearbox. The power is transmitted through L.T. Shaft running on pedestal bearing and connected with the Gearbox, floating shaft and Universal joint assembly. The floating shaft is connected to the L.T. wheel and gear box by means of flexible geared coupling. The motor and gear box are connected by means of universal joint.

Twin Drive Arrangement. In this arrangement L.T. Drive system is provided at each end carriage by individual driving system. Both the drive comprises of a motor, gearbox, floating shaft and Universal joint assembly. The floating shaft is connected to the L.T. wheel and gear box by means of flexible geared coupling. The motor and gear box are connected by means of Universal joint.

In case of goliath/gantry crane only twin drive arrangement possible.

CONTROL PANEL: THE CRANES CAN BE CONTROLLED BY CABIN/PENDANT/RADIA REMOTE & COMBINATION OD THESE.THE COMPONENTS ARE ENCLOSURE IN SHEET METAL BOX STANDARD CONTACTORS ,OVER LOAD REALYS , FUSES ,TIMERS ,TRASNSFORMERS AND ASSESSORIES. FOR SMOOTH JURK LESS DRIVE AND MICRO SPEED OR TWO SPEED DRIVE VVFD DRIVE INSTALLATION IN HOISTING ,CROSS TRAVEL ,LONG TRAVEL AS PER COSTUMER REQUIRMENT.

MOTORS: IN CRANES TWO TYPES OF MOTOR USES CRANE DUTY INDUCTION MOTOR OR SLIPRING MOTOR.AS PER CLASS OF CRANE OR COSTUMER REQUIRMENT.

BRAKES: IN CRANES MANY TYPES OF BRAKES ARE USE.SELECTION OF BRAKE IS DEPENDS ON CLASS OF CRANE AND COSTUMER REQUIREMENTS.

• SHOE TYPE ELECTROMAGNETIC
• SHOE TYPE HYDRO THRUSTER BRAKE
• DISC TYPE ELCTROMAGNATIC BRAKE
