Benefits of technology

[0012]Preferably the mobile lifting assembly includes an idler roller to assist with sliding of the structural member across the mobile lifting assembly. More preferably the mobile lifting assembly includes a winch for pulling the structural member across the mobile lifting assembly on the idler roller.

Problems solved by technology

One of the disadvantages of using forklifts is the height restrictions in a construction site or a mining site.
The use of forklifts in this situation may not be possible because the forklifts may be too tall to enter a car park level.
Other disadvantages of using forklifts also include the need for a number of forklifts and a number of forklift operators.

Embodiment Construction

[0028]The present invention relates to a mobile lifting assembly for transporting and manipulating structural members, such as an I-beam, in construction or mining applications.

[0029]In one aspect of the invention, as shown in FIG. 1, the mobile lifting assembly comprises a primary unit or a body frame 2 with one or more wheels 4 for transporting a structural member (which is not shown in FIG. 1), and at least two lifting devices 6 connected to the body frame 1 for repositioning of the structural member. FIG. 1 shows an embodiment with four lifting devices 6, arranged as two pairs (8 and 10) of lifting devices 6 spaced longitudinally along the body frame 2, which, in the embodiment shown in FIG. 1, is rectangular.

[0030]In some embodiments, the lifting devices 6 may each include a hydraulic ram for raising or lowering the corresponding lifting device. The lifting devices 6 may be individually controllable such that the structural member can be repositioned, such as raised, lowered, r...

Abstract

According to one aspect of the invention there is provided a mobile lifting assembly comprising a body frame with one or more wheels for transporting a structural member, and four individually controllable lifting devices connected to the body frame for repositioning (such as raising, lowering, tilting or rolling) of the structural member. According to another aspect of the invention there is provided a mobile lifting assembly comprising a body frame being adapted to locate on a supporting surface, a lifting device connected to the body frame for raising or lowering a structural member, and a skid resting on the supporting surface underneath the body frame and being arranged to contact the body frame to distribute forces imparted by the structural member on the body frame across the supporting surface.

Description

FIELD OF THE INVENTION[0001]The present invention broadly relates to a mobile lifting assembly for manipulating structural members, such as an I-beam. More particularly, the invention relates to a mobile lifting assembly for lifting and transporting structural members in construction or mining applications.BACKGROUND TO THE INVENTION[0002]Structural members such as I-beams are often required to reinforce structures in a construction site or a mining site. The angle and placement of the structural members are crucial to the reinforcement, which necessitates the accurate positioning of the structural members. Ideally the structural members, when being installed for structural reinforcement, can be manipulated to be placed at various positions and orientations.[0003]Often, one or more forklifts are used for manipulating structural members. One of the disadvantages of using forklifts is the height restrictions in a construction site or a mining site. For example, when a multi-level car ...
