Placing the already fabricated anchor bolts in proper vertical position at reqd. distance and welding with the mesh of the block prior to laying of the block and curing to get required strength. Job includes shifting of pump set from site to workshop and complete overhauling of pump with replacement of impellers, pump shaft, diffussors, neck rings, cover plates and required items required for its repair. Job also includes fabrication of bed plate for mounting of motor on bed plate and proper alignment of pump- motor sets. complete job includes repairing of pump, shifting charges and carriage of material, labour charges and fitment charges at site. Complete job in all respect (Rate to be quoted by the contractor)

Design, Manufacture, Installation / erection , testing and commissioning of 5 Ton capacity electrically operated OHT Crane.The OHT crane should consist of an electrically operated type hoist of 05 Ton capacity to be provided for the operations of raising / carrying / lowering of heavy duty motors and pumping equipments. The crane should span the longitudinal and cross travels by means of travel through boggy wheels on which main crane beams are to be fixed on the beam rails of proper specifications and design, attachments to be fixed on which wheels of trolley move. The hoist has to be mounted on this trolley. The general arrangement consists of following parts :- Set of 2 No. spur gears Gear box reducers – 1 no. Motor for upward and downward movement 5 HP – 1 no. Motor for longitudinal travel 2 HP – DOL type – 1 No. Electromagnetic brake, Speed reduction system, Gear box Panel box fitted with limit switches and pendent control unit which moves with crane, Single rope drum, Steel wire rope 16 mm with hook block. Copper cable of suitable capacity. The electric hoist is to be mounted on trolley which moves on rails fixed on double girder crane. The crane through longitudinal travel boogie gears moves on run way rails fixed on ISMB – 200 which is further fixed on RCC gantry beam / columns as required at site. The operations of crane should be performed by remote pendent control unit operated from the floor level of pump room. Suitable copper cable should be provided along the transverse and longitudinal span of the crane and further connected to the main control unit to be provided and fitted at the pump floor level. The main electric control panel consisting of features as per IS – 3177 is to be mounted on the crane including limit switches etc. All the material used should be of high quality and should conform to relevant IS codes. Complete job includes cost of material, labour charges, tools-tackles charges and fitment charges and charges for working at site Complete job in all respect (Rate to be quoted by the contractor)
