The trolley:

─     The trolley serves as a manually (HF) or electrically (EF) powered hoist trolley for chain hoists or as a crane trolley for the single-girder crane EHB-I and the double-girder crane ZHB-I.

─     The trolley can be mounted on I-beams with a flange inclined up to 15° or a non-inclined flange.

─     The trolley is adapted to the flange width of the I-beam with travelling gear bolts of various lengths. For an exact width adjustment, distance rings are used.

─     The trolleys HF3, HF6, HF/EF14 and HF/EF22 are curve-travelling in certain radii. The drive of the trolleys EF14 and EF22 must thereby lie on the outer side of the curve.

─     The trolley is fixedly connected to the I-beam by a lift-off prevention device and cannot fall down even in adverse conditions.

─    

─     The electric trolley EF:

─     The drive is designed as a pole-variable three-phase motor with electromagnetic brake and gear unit.

─     The drive's gear unit is a maintenance-free, two-stage helical gear unit or a planetary gear unit.

─     The drive has a low and a high speed. The ratio of the two speeds is 1/4.

─     The drive brakes reliably through an electromagnetic disc brake even if the mains supply is shut off or a power outage occurs.

─     Using plug-in connections in the connector housing directly on the drive, the drive can be quickly separated from the rest of the crane’s electrics.

─     Only if the trolley is used as a hoist trolley: The electric trolley EF is provided with current by the chain hoist. The trolley is connected to the chain hoist, which is manoeuvred through a pendant control. Alternatively, the trolley can also be externally controlled (from an external panel for example).

─     Only if the trolley is used as a crane trolley: The electric trolley EF is provided with current by the HB crane installation.
