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 heat 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 groove 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 preset 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 equipped
with 2 travel units, consisting of
planetary gears with double speed
brake motors directly flanged to
the wheels, therefore without
external teeth.
