Heavy duty brakes SM Winches are normally equipped withheavy duty electro-magnetic disk brakes.Brakes are connected directly to the motor shaft. Safe closure is attained by spring force, ensuring operation of thebrake during power failure. A secondsafety disc type brake or (optionally) ashoe brake can be added if required. Motors KCI Konecranes electric crane motorsare specially designed for heavy dutyhoisting applications. The hoist motor sizes for DynAHoist frequency controlsrange from 15 kW to 132 kW and forACE thyristor controls from 15 kW to 90 kW.The modular construction of SM Win-ches allows either one or two main hoistmotors to be combined on the same machine, using a differential input shaft. Alternatively, a separate micro-speedmachinery (100% ED) is available.All motors are IEC standard flange-mounted, with class F insulation. The protection class may be either IP54 orIP55 depending on the site require-ments. Rope drum bearings Two high-capacity ball bearings sup-port the drum at the gearbox end. At the opposite end, a non-rotating shaft supports the drum through a self-alig-ning roller bearing in the drum end flan-ge. This unique arrangement eliminatesdrum shaft fatigue failures.

Hoisting gears Gears are helical, carburized and har-dened to 60 RC, precision-ground toDIN7 (AGMA 10) quality, and are oil bathlubricated. Very large capacity SM 1000-1100 Winches have a planetaryfinal reduction step.

Geared coupling The hoist gearbox is connected to thedrum by a flexible two-stage gearedcoupling. The coupling type allows dy- namic bending and movement of thedrum, without the common fatigue fai-lures. Traversing machineries A hollow shaft gearbox is mounted di-rectly onto the trolley drive axle. The pri-mary end of the gearbox is supported by a flexible shock-absorbing torquearm. A wide range of flange-mountedmotor types is available. Extended Speed Range (ESR) Bogie construction The use of KCI Konecranes’ DynAHoistfrequency controls enables the use ofthe ESR option. This feature allows operation at speeds up to 200% ofnominal with reduced load (maximumof 20% of rated load). Bogie trolley wheel construction allowsbetter distribution of loads to wheelsand cranes girders. In the SM700-1100range, a six-wheel bogie constructionresults in a lighter bridge structure, lessfatigue, less wear and longer life. Auxiliary hoist An auxiliary hoist can be provided byadding a special tow trolley. The towtrolley is connected to the main unit bypinned connections. This arrangement ensures optimal hook approaches.
