Crane Spare Parts

Hoist Gearboxes – Two, Three and Four Stage gearboxes are supplied from Crane Hoisting application. The gearbox casing is made from MS fabricated plates. The casing is thermally stress relieved after welding. The casing is accurately machined on horizontal boring machine. The helical gears and pinions are made from rolled / forged steel of En9 / En19 / Cast Steel material as per design requirement. Gears and pinions are oil quenched and tempered to achieve toughness as well as surface harness. Gear teen are machined hob cut. Case hardened gear teeth are supplied as required. Shafts are supported on antifriction ball and roller bearings. Oil seal seat on shaft are have ground finish. Gears and pinions are Splash lubricated.

CT Gearbox – Two and Three Stage Gearboxes are supplied for Crane CT and LT motion. The construction of CT gearbox is similar to hoist gearbox except that these are provided with inverted T split in housing. The Output shaft can project on both side if so required. For Three stage vertical gearbox forced lubrication arrangement is provided through pump and hoses. Other gearboxes are splash lubricated.

Brake Drums and couplings with brake drums – Brake drums are made from rolled bar or cast steel. The brake drums are fully machined to eliminate vibration. Brake drums are dynamically balanced after machining when required by customer. The drum surface is treated to achieve high hardness for longer life.

Wheels and Wheel Assembly – Wheels are supported in L type bearing blocks. Wheels are made from forged steel/ cast steel and machined accurately. Wheels are suitably heat treated to achieve hardness of 250 – 300 BHN with volume hardening or 450 – 500 BHN with Induction hardening as per customer requirement. Tram wheels with either non ferrous bush bearing or antifriction bearing and open gear attached are also supplied as required by customer.

Compact Enclosed Festoon Cable System – made from enclosed GI track the compact festoon cable system is lightweight and no need to be supported against girder diaphragms. The system is ideally suited for flatform cables are single core cables. The compact nature of cable trolley means better hook approach and the system can be placed at crane girder level. The system is of modular design and can be assembled very easily. Components are available ex stock including PVC flatform cables

Pendent Cable with built in steel wire is available ex stock.

Shrouded Bus Bar – Insulated bus bars are available from 60 Amperes to 1250 Amps rating. These are modular in construction and compact in size. Spring loaded current collectors are supplied that ensure positive contact with current transmitting surface. Conductors are available in GI, Aluminium, Copper and Stainless steel material. Bus bars with expansion joint, hospital bay and suitable for curved track are also available.
