Vibrations free

The geared machine for elevator  ITG 125  is equipped with a monolithic worm shaft with case hardening and tempering treatments which avoids vibrations resulting from the mechanical coupling between the motor shaft and the worm shaft.

The ITG 125 geared machine for elevator is the only traction unit  for elevator of traditional "T" design in the world to be equipped with a third front bearing supporting the worm shaft, which on all other machines of the same type operates cantilever, thus producing greater vibrations and noise.

A lift machine that doesn't cry

Elevator machines with a vertically divided casing can be affected by oil leaks due to the imperfect conjunction of the bore of the oil seal seats, which may not be perfectly circular.

The ITG 125 has been equipped with a flange which houses the oil seal and ensures that the circumference of the boring is perfect and does not give rise to possible leaks.

In addition, the ITG 125 is equipped with oil seals everywhere, even where several competing machines are fitted with simple dust covers.

Always cool

The hoisting machine ITG 125 is equipped with two cooling fans, the first of which is keyed on the worm shaft and runs at the same speed as the electric motor, while the second is a traditional electric fan, installed on the side of the motor casing) activated by the temperature sensor inserted in the electric winding of the motor.

This solution ensures that the ITG 125 engine temperature is always optimal, even in the most extreme environmental conditions or in high-traffic lift systems

The ITG 134 can be supplied with the SSB

Flexibility of installation

The elevator hoisting machine ITG 134 can be easily installed in two vertical positions, as well as in two horizontal ones. Changing the hand of the machine from left  to right  hand and vice-versa required a handful of minutes

Throughout quality

ITG 134 elevator traction units are designed and manufactured to offer the highest quality. The slow shaft has internal and external oil seals, the bearings of the worm shaft  have dimensions that the Competition uses for machines for a capacity of 630 kilos and more, the worm shaft is monolithic, with hard casing and tempering and guarantees the absence of the inevitable vibrations induced by the mechanical coupling between the worm shaft and the shaft of the electric motor, the housing of the double rear bearing is obtained directly from the casting of the casing, to avoid the inevitable mechanical tolerances of a separate bearing box from the casing. These are just some of the different features making  the ITG 134 a decidedly above average quality machine.

Efficiency

The electric motors that equip the ITG 134 geared elevator machines offer high efficiency, thanks to their reduced air gap between the rotor and stator and their careful design.

At ITG we supply motors for each specific application and not motors that are forced to adapt to the need.

Efficiency does not only concern the electric motor, but the whole machine, because the precision of the couplings between the worm screw and the crown wheel in turn ensure maximum efficiency.

Throughout quality

ITG 136 elevator traction units are designed and manufactured to offer the highest quality. The slow shaft has internal and external oil seals, the bearings of the worm shaft  have generous dimensions, the worm shaft is monolithic, with hard casing and tempering and guarantees the absence of the inevitable vibrations induced by the mechanical coupling between the worm shaft and the shaft of the electric motor, the housing of the double rear bearing is obtained directly from the casting of the casing, to avoid the inevitable mechanical tolerances of a separate bearing box from the casing.

Skyrocketing static load

Thanks to its 5.200 kg the elevator hoisting machine ITG 160 has the highest static load of its segment.

The very high static load allows the ITG 160 to be used in many applications normally reserved for much more bulky, expensive machines non-installable  in MRL elevator systems.

Sound quality throughout

ITG 160 elevator traction units are designed and manufactured to offer the highest quality, and retains all the main features of the machines of the ITG 130 Series. The slow shaft has internal and external oil seals, the bearings of the worm shaft  have generous dimensions, the worm shaft is monolithic, with hard casing and tempering and guarantees the absence of the inevitable vibrations induced by the mechanical coupling between the worm shaft and the shaft of the electric motor, the housing of the double rear bearing is obtained directly from the casting of the casing, to avoid the inevitable mechanical tolerances of a separate bearing box from the casing. These are just some of the different features making  the ITG 160 a decidedly above average quality machine.

Convenience

The geared machine for elevator ITG 160 is easy to transport, to install and to maintain, since any maintenance operation does not require specific equipment and can be carried out with normal work tools.

However, the most important element of its convenience is its extreme reliability.

In all cases where it is necessary, the ITG 160 can be supplied with hardened pulley grooves, so as to withstand over time both the conditions of higher traffic or unfavorable conditions of specific pressure of the ropes
