Gearbox(1)
The 2 or 3-stage planetart gear reduces the speed of the electric motor
to the RPM necessary for the drum.
All gears of the planetary gear are made of hea-treated high quality steel.

Electric brake motor(2)
Three-phase asynchronous 1 or 2-speed motor with cone rotor and integrated
cone brake driven by a coil spring.
The brake release is due to the sliding of the rotor after switching-on of the power supply.

Rope guide (3)
The rope guide basically consists of two parts: a guide ring and a pressure spring that properly guide the rope on the drum grooves.
The guide ting maintains the rope in position during the incoling, preventing it comming-off the groobe and, when the load oscillates, is guided by a fixed bar and runs on bearings.

Load limiter (4)
All "M" series hoists with 2 and 4 rope falls are equipped with a load limiter with
3 reaction thresholds.
The load limiter consists of an
electric-mechanical system with pre-set springs acting on two microswitches
stop all movements, exception made for the lowering of the load.
The first threshold activates a WARNING, the 2nd stops the function.

Low headroom trolleys (5)
Low headroom trolleys are equopped
with 2 travel units, consisting of
planetary gears with double speed
brake motors directly flanged to
the wheels, therefore without
external teeth.
