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 extension control boxes (PECBs) (13) connected between an additional power source and a plurality of additional modular lifting units
