Embodiment Construction

[0056] figure 1 and figure 2 A first embodiment of a control system according to the invention for controlling a plurality of modular lifting units 12 is shown in . The control system includes a main control box 10 for controlling a plurality of modular lift units (MLU) 12 connected in a daisy chain configuration. Optionally, the control system further includes a plurality of power expansion control boxes 13 for distributing electric power to additional modular lifting units 12 when the number of MLUs exceeds the limit that the main control box 10 can distribute electric power. Each modular lifting unit 12 may be a lifting jack similar to that described in PCT / AU2014 / 000224 and includes a variable speed drive (VSD) 14 for controlling the ( figure 1 and figure 2 not shown in ) the speed of the electric motor / gearbox 16. Each modular lift unit 12 is also fitted with a 24 volt interface relay 18 .

[0057] The control system includes: one or more power sources 20 for provi...

Abstract

A control system for controlling the operation of a plurality of modular lifting units (12). The control system includes a power source (20) for providing power to each of the modular lifting units (12). A main control box connected between the power source (20) and the modular lifting units (12), comprises a mode switch (28) for switching the system between two control modes: a group mode, in which the plurality of modular lifting units (12) is controlled synchronously as a group; and, an individual mode, in which any one of the modular lifting units (12) is controlled independently of the other units. In group mode, synchronous movement of the modular lifting units is achieved by setting each unit to run at the same speed. The control system may also comprise one or more power extensioncontrol boxes (PECBs) (13) connected between an additional power source and a plurality of additional modular lifting units

Description

technical field [0001] The present invention relates to a control system for controlling a plurality of modular lifters, in particular, but not exclusively, to such a control system for raising and lowering a building structure using a plurality of lifting jacks. Background technique [0002] In co-pending International Patent Application No PCT / AU2014 / 000224, the content of which is hereby incorporated by reference, a method of constructing a multi-storey building structure is described. In the method of PCT / AU2014 / 000224, the upper floors of the building structure are first constructed at ground level and then raised upwards to the required height, after which the lower floors of the building structure are constructed below. This construction method achieves significant cost savings and safety improvements when constructing building structures because it eliminates the need for scaffolding and workpieces to be installed at various heights during the construction of higher ...
