Since our inception in the year 1991, we are engaged in manufacturing and exporting Industrial Cranes to the esteemed customers. These cranes are manufactured by making use of optimum grade raw material that is obtained from the most appreciated vendors of the market. Our team of adroit engineers have the acumen to test these products as per international standards such as IS 807, 3177, 3938 & 4137. Patrons can avail these Industrial Cranes from us in various customized version at market leading prices.
Besides, load spectrum (loads to be lifted in day-to-day operations & long term objects are also considered) greater standardization & jig manufacturing techniques in components insure shorter delivery period, interchangeability, in case of maintenance and availability of spares.
The girders of the crane are of box type construction for more tensional rigidity, low head room and aesthetically pleasing appearance, if span is more than 12mtr, for lesser span rolled Section Beams are used. The box girder is designed to give maximum strength to weight ratio with no excess self weight. This effects life of crane components like wheels, bearings & gears in particulars. Maximum deflections of the bridge girder will be limited to 1/600 of the span if the span is less than 12mtrs. & 1/750 if the span is more than 12mtrs with loaded trolley located in central position.
L.T Drive is central in case of span of less than 12mtrs and twin in case of larger spans.
The rope drum is Steel Fabricated/Seamless pipe with full length shaft with specially designed flexible coupling between Hoist gear box & rope drum. Hoisting rope is of “Usha Martin” make flexible type of best plough steel 6x36 construction 160/165 sq.mm. Tensile strength & IS-2200, steel core for furance duty cranes.
The brakes are FAIL-SAFE type(apply automatically in case of power interruption)
Gear boxes have C.I/M.S fabricated casing stress relieved. The insides of the gear boxes are painted with oil resistant paint. The teeth of the gear & pinion shafts are cut on imported Hobbing machine with standard hob full dep. 20 degree pressure angle with profile correction to avoid undercut.
The couplings are Gear type to compensate for slight misalignment with out imparting additional stress on stationery members, bearings & pedestals thus maintenance work is considerably reduced.
The electrical/control equipments consists of:
The cranes are manufactured as per requirement of ISI specification No. 3177/1999, 807/1976, IS4137/1985 for crane. All the wheels are hardened to give long working life and wheel assemblies are Jig Drilled for interchangeability
The motors are connected to the Gear boxes with gear type coupling to compensate for slight misalignment with out imparting additional stress on stationery members, bearings & pedestals, thus maintenance work is considerably reduced.
