Girder Speed : 0.5 - 40 m / minute via inverter

Diameter of wheels / girder : 4 Demag wheels with a diameter of 200 mm

Wheel material : GGG 70 / nodular cast iron / includes graphite for permanent lubrication of the rail.

Gearbox girder : 2 x Demag gearboxes, model AME 30DD

Girder Motor / model : 2 x Demag motors, model ZBA 90 B4

Motor / power : 2 x 1.44 Kw.

Control: The cranes will be operated via a Demag push button station movable along of the

girders. Electrification along of the girder : Flat cable along of 1 of the girders (festoon type).

Voltage of operation : 440 V / 60 Hz / 3 phases

Voltage of control : 110 V

The crane will include an audible and rotating alarm system that will be activated when the crane and/or the trolley movement are activated.

The crane will include limit switches at the ends of the crane girders and of the runway. In this way we guarantee that the crane and / or trolley get into the slowest speed before they

get in contact with the buffers.

Dead weight of the crane : 8,912 Kg aprox. Maximum wheel load on the runway : 4,836 Kg aprox.

2 x set of electrification along the bay for a length of 168m and for 440 V / 60 Hz / 3Fases. We are considering that the customer will submit for this electrical feeding 1 power supply line at the altitude of the runway and located at the middle of the runway.

The electrical feeding system includes all accessories to guaranty the correct operation of the crane.
