Famous Mark EOT 5~600T Double beam overhead crane /Bridge Cranes

A Bridge Crane consists of an assembled structure which spans between parallel rails or runway tracks, and is adapted to carry a suspended load horizontally along the runway. Bridge cranes can be top running or under-hung with single or double girder configurations. They also incorporate hoists on trolleys to move the load laterally as well as vertically. Bridge cranes can be mobilized via push trucks, geared, or motorized end trucks.

We have been designing, manufacturing, and installing custom designed bridge cranes over the past 25 years. All cranes have been designed in accordance with ISO/FEm specifications

GEAR BOX : The gear box is made of high grade cast iron. The precision spur gears are machined from alloy steel and are fitted with ball / needle roller bearings. The gear box is filled with grease.

ROPE DRUM : The rope drum is rolled welded and precision machined. This rope drum is supported on large diameter roller bearings on both ends and the drive is through internal gears.

This rope guide moves on the drum like a nut and prevents the rope from overriding and loosening.

ROPE : Generally 6 x 37 / 6 x 36 construction fibre core preformed type, ungalvanised wire rope is supplied. (Galvanised and steel core wire ropes can also be supplied, if specifically asked for).

LIMIT SWITCHES : Every hoist is provided with built in limit switches to control the top and bottom positions of the hook. Tappets can be adjusted on limit switch rod to any position in between the range provided. These limit switches are actuated by the rope guide.

CONTROL : For single beam crane the hoist is controlled by a pendant push button station. For double beam crane usually to use cabin control.

MICROSPEED : All hoists can be fitted with a micro speed attachment which reduces the hoisting speed to 1/10th of the main hoisting speed. The micro speed attachment works independent of the load and main hoist. There is a separate control for the micro speed. This arrangement is invaluable in the handling of bulky, heavy and delicate loads.

TESTING : Every hoist unit is tested at 125 % of the rated load capacity on single fall of rope. Even the components pass through rigorous inspection tests before the hoist is approved for dispatch.

EXTENDED TROLLEY

These are particularly required when the load is bulky or far handling material form furnaces / chemical baths. This trolley can also be provided with two hooks to deal with loads like paper rolls, logs etc. When the loads go beyond the overhead track, an outrigger type of extended trolley is indispensable These are used for loading on and unloading from ships in stream. Driver's cabins can also be built with trolley.

CRAB

Crabs can be supplied as standard units can be custom made. They offer maximum advantage when working in open. These crabs can have single or twin hoists units as required. The driving arrangement can either be with hand geared or motor driven type. Micro speed arrangement in hoisting can be provided if required.

TWIN HOISTS ON MONORAIL TROLLEY

For exceptionally high height of lifts this arrangement is very useful. It also offers the option of two hoisting speeds.

MICRO SPEED ATTACHMENT

For exceptionally high height of lifts this arrangement is very useful. It also offers the option of two hoisting speeds.

FIXED MOUNTED HOIST

These are available in all types of mountings, eg. floor mounted, ceiling mounted, wall mounted etc. They are used for loading and unloading transportation vehicles, through floor hatches or outside the wall, and for serving production machinery. When ordering, please state in what position the hoist is to be mounted and wire outlet required.

HOIST WITH TROLLEY

Hoists can be equipped with trolley for horizontal traveling, The trolley is fabricated from components bolted and welded together and carried by traveling wheels supported on all bearings

Smaller loads can be moved with a push type trolley whilst the hand chain or motor driven should be used for heavier loads. The motor driven trolley would be the best solution if the hoists unit is required to move loads rapidly. The driver motor is of squirrel cage type with built in brake. The motor drives one or more of the trolley's wheel's gear rim. Wherever there are limitations to the variable head room, short head room trolley can be supplied

HOIST WITH FLEXIBLE TROLLEY

When the trolley has to negotiate a curved track or the material movement is from one bay to another, this type of arrangement fulfills the requirement.
