DRIVE UNIT FOR CRANES
“DGP” series offset geared motors are built specifically for handling lifting systems on rails, such as, for example, travelling cranes, gantry cranes and or related running trolleys. The Drive units for cranes are designed for travelling loads through horizontal handling operations when installed on runway rails that allow the correct running alignment.
The wheel groups “DGT” in combination with “DGP” series offset geared motors, are highly reliable modular components capable of responding flexibly and efficiently to the needs for operating safety, cost efficiency and the rapid setup of drive units for cranes by manufacturers of machinery and industrial lifting and handling installations.
The drive units for cranes are configured in 6 sizes covering the following operating limitations:
-
Capacity of the lifting and or traversing equipment from 1000 to 40000 Kg.
-
Running speed: single speed from 3,2 to 25 m/min; two-speed from 12,5/3,2 to 80/20 m/min
The modularity of the basic components (wheels, reducers and motors) allows for the composition of drive units for cranes in two configurations: the drive group and the idler group.
“DGT” series wheel group

- The drive wheels Φ 125, Φ 160, Φ 200, Φ 250, Φ 315 are carbon steel moulded, the Φ 400, Φ 400 R wheels are iron casting.
- Wheels revolving on radial ball bearings permanent lubricated, the wheel Φ 400 R, increased capacity, is supplied with radial roller bearings.
- They are available in either idler operation or as drive units in combination with an Offset geared motor.
- Wheels are available in a standard version with a double flange, and can be supplied, on request, in various driving band widths in relation to the type of
the runways' rail they are intended to run on.
- Whether in idle or drive operation, the wheels are supported and contained within and electro-welded plated frame which acts as a support box for the entire group, and as an joining element between the operating end carriage frame or trolley with which the wheel group is to be assembled.

- The reducers are designed as an “Offset geared motor type” with a concave shaft, featuring parallel axes with two or three stages of reduction, and in a permanent oil-bath lubrication.
- Engineered with cylindrical high resistance steel gears, featuring spiral toothing, thermically treated, entirely supported on ball bearings.
- The electric motors are asynchronous, featuring a progressive start-up, with a standard ventilation, self-braking with axial shifting of the rotor guaranteeing a fast, reliable mechanical braking.
- Electrical power 400 V - 50 Hz.
- Protection of electrical parts:
- IP55 Motor
- IP23 Brake
- Class “F” insulation Motor
- IP65 Limit switch; max insulation voltage 500 V
