Description

Trolley for bridge crane system and bridge crane system Technical Field The present utility model relates to a trolley device (trolley arrangement) for a lifting machine (hoist) of a crane system, in particular to a trolley for a bridge crane system and a bridge crane system. Background In a typical bridge crane configuration, the trolley is mounted to an overhead beam or gantry. The trolley includes wheels to allow the trolley to move along the beam to provide horizontal movement of the trolley. The pulley system may be mounted to a trolley to support hooks or the like to lift a load in use. A "low clearance" crane system may be used where vertical working space is limited. In such an arrangement, it is desirable that the various components of the trolley are disposed as high as possible relative to the gantry, so as to provide increased clearance between the trolley and the ground in use. Examples of such arrangements 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 plurality of cross members, one of the cross members being configured to support a portion of a lifting member configured to lift a load in use, at least one first beam extending between the cross members, the first beam being spaced apart from the cross members in a vertical direction perpendicular to the cross members, and a plurality of arms extending between the cross members and the first beam to provide a connection between the cross members and the first beam, wherein at least one of the arms extends in a direction which is angled relative to the vertical direction. The trolley may comprise a second beam extending between the cross members. The second beam may be connected to the cross member via a respective arm. The arms connected to the second beam may be angled with respect to the vertical (i.e., such that all arms are angled). The arms connected to the first beam may be parallel to each other. The arms connected to the second beam may be parallel to each other. The arms connected to the second beam are angled relative to the vertical in the opposite direction to the arms connected to the first beam (i.e., in a divergent arrangement). The arms may be angled between 1 and 30 degrees relative to the vertical. The arm may be angled between 1 and 10 degrees relative to the vertical. The arms may be angled outwardly such that the portions of the arms that are connected to the beam are spaced more apart than the portions of the arms that are connected to the cross member. The beam may extend outwardly relative to the trolley. The beams may extend outwardly parallel to the axis of the cross member. At least one of the arms may comprise a wheel or a roller. Each of the arms may include a wheel or roller. In use, the wheels or rollers may provide movement of the trolley along the gantry or bridge. At least one of the arms supports a portion of the lifting mechanism to raise the lifting member in use. At least one of the arms may include a plurality of mounting surfaces to allow mounting of the lifting mechanism to the arm. The mounting surfaces may be provided on opposite sides of the arm such that the lifting mechanism may be mounted on opposite sides of the arm accordingly. The first beam and/or the cross member may comprise an arcuate tubular profile. The cross member and the first beam form a U-shaped profile in a direction perpendicular to the cross member. The cross member and the beam(s) may extend perpendicular to each other. The cross members may be parallel. The beams may be parallel. One of the cross members may be configured to support a sheave device. One of the cross members may be configured to provide an attachment point for the lifting member. According to a further aspect, there is provided a bridge crane system comprising the trolley of the first aspect. The first cross member may be disposed on a first side of a gantry of the bridge crane system. The second cross member may be disposed on a second side of the gantry. One or more beams may span the gantry. The wheels may engage the gantry. The lifting mechanism may be provided on the side of the gantry. Bridge crane systems may include low profile, low headroom, or low bridge systems. Any aspect of the utility model may be combined with any other aspect of the utility model, where applicable.
