Description

Trolley for bridge crane system and bridge crane system thereof Technical Field The utility model relates to the field of bridge cranes, in particular to a trolley for a bridge crane system and the bridge crane system thereof. Background In a typical bridge crane configuration, the trolley is mounted to a bridge beam or gantry. The trolley includes wheels that allow the trolley to move along the beam to provide for its horizontal movement. A pulley system may be mounted to the trolley to support a hook or the like to lift a load in use. A "low headroom" crane system can be used where the vertical working space is limited. In such an arrangement, the various components of the trolley are preferably arranged as high as possible relative to the gantry, so as to increase the gap between the trolley and the ground in use. Examples of such devices are provided in WO 2015/110705, US 5461985 and US 2005/0092201. The prior art systems include a number of drawbacks. The present utility model is directed to overcoming or improving one or more of the problems in the prior art solutions. Disclosure of utility model According to a first aspect there is provided a trolley for a bridge crane system, the trolley comprising a lifting mechanism for raising or lowering a lifting member in use, a plurality of arms, at least one arm being configured to mount the lifting mechanism, a beam extending between the arms to connect the arms in use and to span the gantry, and wherein the at least one arm comprises a plurality of mounting surfaces to allow mounting of the lifting mechanism to the arms, and wherein the mounting surfaces are provided on opposite sides of the arms such that the lifting mechanism can be mounted on opposite sides of the arms accordingly.

The lifting mechanism may span a direction parallel or adjacent to the cross member. The spool or spindle of the lifting mechanism spans between the two arms. The lifting mechanism may be detachably attached to the arm. The lifting mechanism may include a bracket configured to mount to one or more arms. The bracket may include a face configured to engage the mounting face on the arm. The bracket is shaped to engage both sides of the arm. The bracket may support a gear box of the lifting mechanism. The trolley may comprise a plurality of cross members. Corresponding beams may extend between the cross members. The cross member and the beam may be connected via respective arms. The arm and the beam form a U-shaped profile in a direction perpendicular to the arm. The beam may be spaced apart from the cross member in a vertical direction.
