In a cable car system, a suspension system is understood to be an asymmetrical steel structure - seen from the side - with which the transport equipment or load is attached to the carriage or the clamp and thus to the support cable or the hoisting cable .

Surname

The name hanger comes from hanging and means hanging down . Originally mainly ornaments (e.g. earrings) on the body and weapons on clothing (e.g. on the belt ).

Form and execution

The asymmetrical shape of the hanger in a cable car system is necessary so that the hanger can pass the cable car supports laterally with a safe distance and that a transverse oscillation does not lead to the hanging or stripping of the hanger on the support structure. In the case of aerial tramways without supports, the suspension can have a symmetrical shape or encompass the suspension ropes entirely (see e.g. Masadabahn ). The hanger does not have to consist of a stable, torsion-free construction, but can also be made entirely or partially from steel ropes or chains (especially for material ropeways ), see also the Lagazuoi cable car ( Italian : Funivia del Lagazuoi ).

On a large hanger, e.g. As in a pendulum cable car (see, eg. B .: Klein Matterhorn ), can also be a ladder be attached to the hanger to the cableway staff to allow the rise of the canopy to the drive.

With some types of cable car (e.g. the aerial tramway), the hanger is also used to fasten the pull and counter ropes or the hoisting rope through which the carriage, the hanger and the equipment are moved.

In the case of cable cars, a load suspension system is the suspension system that does not carry a cabin etc., but rather that the load is attached directly to it. Hoists (e.g. cable winches) are part of the sling and not of the transport equipment / load.

In the case of T-bar lifts , the term hanger (towing hanger) is sometimes only used to refer to the pull-in device (also: pull-in device), the hanger rod (also: hanger tube) with the hanger head is then considered separately. The tow bars (long ironers, short ironers, plates) are always differentiated as driving equipment and do not belong to the hanger.

With the chairlift, the suspension ends at the upper attachment point of the chair.

With the Funifor, there is an extremely short hanger to the vehicle equipment, where compact, flat station structures are possible.

Verification

The transition from the hanger rod / hanger structure to the drive or to the hoisting rope clamp is the hanger head, which is exposed to significant loads in every direction and therefore, such. B. a hanger bolt, special attention must be paid when checking.
