| ELECTRIC WINCHES | ||
| All Antal winches, from model W40ST to model W70ST and the maxi W90.3ST, may be
fitted with an electric motor. Only the models with a bronze drum are fitted with motors, as they are more suitable for heavy-duty applications; on request the aluminium drum may also be “reinforced”, applying a special toothed crown gear of high resistance alloy. HORIZONTAL AND VERTICAL MOTORS All the winches may be equipped with a horizontal motor and speed reducer with a worm screw. The largest models may be supplied with a vertical motor which uses a high-efficiency hypocycloid speed reducer. Both solutions have been studied to ensure particularly compact dimensions and maximum silent operation. MANUAL USE Simply insert the handle to disconnect the speed reducer-motor unit. Greater safety: accidental starting of the motor does not affect the winch, avoiding dangerous turning of the handle. Greater efficiency: the speed reducer-motor unit does not turn in manual use, avoiding needless friction. |
SPEED Electric winches maintain two speeds both in manual use (inverting the direction of rotation of the handle) and in electric use (pressing one of the two control buttons). It is of fundamental importance to be able to choose the most suitable speed for the manoeuvre that you want to perform; this allows fast recovery of the first part of the manoeuvre and more careful regulation in the final stage. In electric winches the speeds are higher than in manual use. The recovery speed, indicated in the tables, is measured without a load; in the presence of the maximum load, a speed reduction of up to 30% must be considered. All our electric winches are self tailing and come supplied with a chrome-plated bronze drum. |
