Reduction Gearboxes & Electric Motors, Lift Duty

Raman Engineering Co, an ISO 9001:2000 company, was founded by a veteran in the field of lift duty reduction gearboxes and motors. The company strictly follows the ISI/BS standard norms. The lift units have been designed for special purpose of lift where silence and smoothness are of most necessary importance. The gear case is of high quality close grained cast iron conforming to IS 210 of high grade. Its rib design provides maximum strength and surface area for heat dissipation. The entire design is based mainly on BS 721 to high accuracy. IS specification are used wherever necessary. The worm is made from high quality hardened steel generated, ground and super finished. The worm wheel is made from centrifugally cast nickel phosphor bronze conforming to BS 1400 PB-2 rim fitted with cast iron centre. Sleeve bearings are used on worm shaft with angular contact ball bearings being used to take thrust. Sleeve bearings are provided on wheel shaft for maximum load carrying capacity. Oil seals are not provided in gearboxes. All gears have limited backlash for lift operation. Special care is taken for oil circulation so that ample quantity of oil reaches all sleeve bearing imparting longer life. These high quality units offer maximum economy with minimum maintenance and require only periodic oil checking.
