Heavy-duty and motor-driven cable festoon systems |
|
 |
The requirements on the capacity of
container cranes hasve been increasing constantly in recent years.
Trolley speeds exceeding 200 m/min are
quite common, so that conventional cable festoon systems are bumping up
against their technical limits.
New approaches have been introduced to
cope with the ever higher trolley speeds and the associated load on the
cable material. A combination of motor-driven and drive-less cable
festoon systems represents one
cost-conscious solution.
For careful handling of the cables, it is necessary at speeds above 200
m/min to provide some cable festoon systems with a drive in order to
achieve better motion alignment between the crane trolley and the power
supply. In the application, the number of motor-driven cable festoon
systems depends on the individual crane and its technical parameters,
e.g., trolley track, speed, acceleration, cable weight, number of runs,
etc.

The design developed by VAHLE
of motor-driven cable festoon systems distinguishes itself
through its reliability and careful handling of the
cables. In particular, even under poor weather conditions, such as
storms, snow, or rain, the system has proven effective on
previously equipped container cranes.
For a large part, the maintenance is limited to a regular visual
inspection.
Series WA 145 R - frequency-regulated AC motor with a
power output of 2.2 or 3.0 KW. The permissible load equals max.
500 kg and the polyurethane-coated steel rollers have a diameter of 140
mm.
Series WA 155 R - frequency-regulated AC motor with
a power output of 4.0 or 5.5 KW. The permissible load equals max. 750
kg and the polyurethane-coated steel rollers have a diameter of 160 mm.
