Description

Mounting device for mounting lifting member of crane system, crane trolley and crane thereof Technical Field The utility model relates to the field of crane lifting, in particular to a mounting device for mounting a lifting member of a crane system, a crane trolley and a crane 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 its horizontal movement. A pulley system may be mounted to the trolley to support a hook or the like to lift the 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 WO2015/110705, US5461985 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 of the present utility model there is provided a mounting device for mounting a lifting member of a crane system, comprising a housing comprising a sheave to constrain the lifting member, the housing comprising a channel to receive a portion of a crane trolley in use, and a securing member configured to be attached to the trolley in use, and wherein the housing comprises a recess therein to receive the securing member to constrain the position of the housing on the trolley. The mounting means may comprise a sliding member. The slide member is configured to be disposed between the housing and the trolley in use. The sliding member may facilitate relative rotation between the housing and the trolley. The sliding member may be configured to prevent lateral movement (e.g., movement in an axial direction of the cross member). The sliding member may comprise a low friction material. The sliding member may comprise a tube or sleeve. The securing member may include one or more stop members. The stop member may limit rotation of the housing relative to the trolley. The stop member may comprise a raised lip or ledge. The stop member may comprise a fastener. The stop member may comprise an end of the securing member. The stopper member may be provided at one end or both ends of the fixing member. The one or more stop members are positioned such that the housing can be rotated relative to the trolley through a predetermined angular range. The fixing member may be sized such that a gap is formed between the fixing member and an end of the recess. The housing may be moved into/out of the gap to provide rotation of the housing. The housing may comprise a single unitary sheet. The fixation member may be curved/arcuate. The fixing member may include an arc-shaped bracket. The recess in the housing may comprise an arcuate slot. The slot may be shaped to correspondingly receive the bracket. The fixing member may allow rotational movement and prevent lateral movement. The securing member may be secured to the cross member in use. The sheave may be rotatably mounted to the housing about a first axis of rotation. The housing may be mounted to the trolley about a second axis of rotation in use. The second axis of rotation may be perpendicular to the first axis of rotation. The sheave may include wheels or rollers. The sheave may include grooves or slots. The sheave may be fixed to the housing via bearings or the like. The sheave may be disposed at one end of the end housing and the passage and at a second end of the housing. The contour of the housing may be U-shaped. The channel is defined by the apex of the U-shape. The fixed member and/or the sliding member may comprise one or more attachment structures allowing to connect the trolley in use. The attachment structure may include a fastener and/or a hole recessing the fastener. The lifting member may comprise a rope or a chain. According to another aspect, there is provided a crane trolley comprising the mounting arrangement of the first aspect. The housing is mounted to a support, beam or bar of the trolley. The support/beam/bar may provide a cross member. The cross members may be connected via respective beams. The cross member may be connected to the beam by a respective arm. The arm may support a wheel or the like. The housing is rotatable relative to the support/beam/bar. The housing may be constrained near an axial position on the support/beam/bar. The sliding member may be fixed relative to the support/beam/bar. The support/beam/bar may be fixed (i.e. non-rotatable) with respect to the trolley. The crane trolley may comprise a lifting member configured to support a load in use, wherein a first portion of the lifting member is connected to the lifting mechanism and a second portion of the li
