Long life product
Wire rope winches from Büll are the result
of a long experience in the field. We assure a high quality product with a
certified construction.
The modular solution offers a big number of variations, to meet the
customer requirements.
Motor
Single or dual speed motor (multi-pole solution). We have chosen the
cylindrical type of motor in order to reduce any kind of problem in
maintenance, avoiding the sliding of the rotor. Our motors come from the
market, according to IEC rules.
Brake
Electro-magnetic disk type; asbestos free. No sliding of the shaft;
the brake torque is adjusting in a very wide range of values. Low current
input and noise.
Spur gear
Three steps epicyclical type.
Frame
A rugged frame made by two side steel machined flanges, connected by
four high quality steel rods.
Drum
Single or double rope steel drum with maintenance free central
bearing.
Safety limit switch
Worm gear safety limit switches for hook position, with possibility
of adjusting for intermediate positions.
Electric control
Contactor control box with “emergency stop”.
Variable frequency control is also available.
Overload safety device
The device checks the current input of the motor. Its function is to
measure the minimum overload to the motor and than to stop the movement, in
order to protect both the operator and the machine, when a load, over the
nominal capacity, is applied to the hook. The device has a timer in order
to prevent the intervention at the starting.
