Compared with ordinary stage electric hoists, portable truss winches have more prominent advantages. In terms of load-bearing capacity, ordinary electric hoists are mostly suitable for light equipment under 50kg, while the rated load-bearing capacity of portable truss winches generally reaches 100-500kg, and some professional models can even bear overweight loads of more than 800kg, meeting the hoisting needs of large-scale stage equipment.
In terms of synchronous control performance, the control unit equipped with portable truss winches can realize the linkage operation of multiple winches. It adjusts the running speed and position of each winch through real-time data feedback, ensuring that the synchronization error does not exceed 2mm when multiple sets of equipment on the truss are adjusted simultaneously, and avoiding uneven stress on the truss caused by asynchronous equipment operation.
In addition, most ordinary electric hoists are fixed-installation type, while portable truss winches are equipped with quick disassembly and assembly interfaces, which can complete connection or disassembly with the truss within 10-15 minutes. Moreover, the winch body is equipped with foldable support feet and universal wheels, facilitating transportation between different venues and adapting to the multi-venue tour needs of large-scale performances.
