Double Beam EOT Cranes

Capacity   :   Up to 100 Tones,
Span         :   Up to 25 Mtr.
Lift of lift   :  6 Mtrs & Above

End Carriages:
End carriages are fabricated from rolled steel sections or plates and are provided with diaphragm members, connected to the girders to prevent cross bending. The end carriages will be of Single piece construction which reduces the change of bending during transportation. Rubber Buffers will be fixed  on either side of the  each end  carriage.

Walk Way:
M.S. Chequered plate with hand railing is provided for maintenance of the crane on one side of bridge to the full length of the crane span and two short lengths on other side.


Crab Assly:
The crab frame is fabricated from steel sections and carries hoisting and cross traverse machineries. Double flange carbon steel wheels with support block of L type housing bearing are provided.  The L-Type bearing have following advantages.

• It provides two load bearing surfaces at right angle to take vertical as well as horizontal Load.

• Wheel load is being transferred through machined pad which prevent failure of holding bolts.

• Easy of maintenance during break down. Complete wheel assembly can be changed in few minutes.

Long Travel Assembly:
Single Drive Arrangement & Twin Drive Arrangement are provided as per span and capacity  of the crane. Each drive comprises of totally enclosed oil lubricated horizontal type gear box, Electric motor and fail safe type brake. In case of single drive out put shaft of gear box extends on both sides which drives one wheel of each end carriage on the principle of floating shaft In case of twin drive arrangement out put shaft of gear box extends on one side and drives one wheel of the end carriage.

Geared Coupling:
The entire transmission system on the cross traverse and long travel gear boxes is designed with use of geared flexible coupling which have the following advantages :

• Simple in design and composed of a few parts

• No springs to crystallize or break

• No rubber bushes to require frequent replacement

• It is self-aligning with no bending action at any point of its revolution

• Crowned teeth are free to align themselves as in ball and socket joint

• Can be used on reversing service without any noise or vibration

• Exceptionally long life

• Accurately machined for ultimate performance

• Simple to align, install and easy to maintain

• In capacity of transmitting torque it is the smallest in size and weight in comparison with any other flexible coupling
