Bridge Construction
The bridge girders shall be fabricated out of steel plates welded together to form a box. Butt welds are carried out on webs and flanges and radiography test are done to ensure continuity of plates. In addition full length and short diaphragms are inserted to transmit the trolley load to the web plates. The cross travel rails are placed at the center of top flange. All diaphragms shall bear against top flange.

The vertical deflection caused by the safe working load with crab in the center will not exceed 1/900 of the span. The natural vibration dampening time shall not be more than 15 seconds.

Travel Wheels
The wheels are forged out of En-9 material volume hardened to 280-300 BHN. Each wheel is fitted with two numbers roller bearings of approved make mounted on L- type bearing housings for easy removal & fitting. Grease nipple should be provided at suitable place for convenient greasing and the grease be retained.

Crane Braking
AC operated thruster brake will be fitted on each individual gear box of each motion. The brakes will be of post type with hinged shoes, lined with good quality reinforced bonded brake lining and arrange for easy adjustment for the necessary wear on lining time to time. As during power failure the above thruster brake will apply and the crane motion shall stop immediately.

Hoisting Machanism
This will consist of rope drum fabricated out of seamless pipe duly stress relieved and machined. The drum shall be of proper diameter as per the standards and of sufficient length to take full amount of rope without overlapping when the hook is in the highest position. When the hook is in lowest position, there will be at least two full turn of rope remaining on drum. The rope will be properly clamped at both ends The drum will have right and left hand spiral grooves machined to suit the required size of wire rope. The drum will be connected to the hoisting gear box with a flexible geared coupling joint.

Crane Gear Boxes
The Gear box of all motion will be helical type of the required HP rating. The casings will be M.S fabricated type duly stress relieved. The gears are machine cut out of En-9 forged material duly hardened to 230-250 BHN. The pinions will be machine cut of En-19 material duly hardened to 250-270 BHN. The gears and pinions will be helical type. The output shaft and pinion shaft will be mounted on ball & roller bearing of approved make. The complete gear train shall be enclosed and oil lubricated. The two halves of the gearbox casing are properly machined to avoid oil leckages. All the extended shaft and end covers on gear box are provided with good quality oil seal to prevent any leakage. Limit switches :
There will be an gravity type limit switch in addition to the geared rotory limit switch for hoisting motion. Series type limit switches with single arm spring loaded type will be provided for cross travel and long travel motion. All limit switches shall be connected only in interlock circuit.

Rope Hook And Sheaves
The factor in safety will not be less than 6 / 8 for hoisting motion depending on class. Sheaves shall be of M.S profile cut / Cast Steel duly machined & mounted on ball bearings. Guards will be fitted to prevent the rope sheaves with opening for wire rope entry. Even when the hook is at lower most position to rest on the ground and rope allowed to fall slack, the rope will not come out of the pulley groove.

Motors
All the motors will be 150starts/hour, 6pole, 40%CDF slipring type. These shall be totally enclosed type fitted will ball / roller bearing. The motor will have class 'B/F' insulation and will comply with IS: 325 according to manufacturer standard. All motor shall be suitable for use of 415 V. 3 phase, 50 cycles, AC supply. The will should be of ALSTOM / BHARAT BIJLEE / KEC make only and will be for crane duty application only.

Wiring :
The crane will be supplied complete with all wiring and materials. Junction box on the crane bridge will be provided if necessary.. All Flexible wiring will be with PVC insulated flexible unarmored cables having copper conductor. All fixed wiring will be copper armoured. Wire and cable will be of 1100V grade. The fixed cables will be laid in perforated cable trays properly dressed. All electrical wiring and installation shall strictly confirm to IS Act, 1910 and I.E.E. Rules. 1956 and other standard practice as adopted by the I.S.I. All control terminations will be ferruled such that the numbers are clearly visible from out side, crimped terminations will be provided for control cables and as far as possible for main cables. Proper earthing will be provided to the motor frames, control panel frames, crane structures etc.
