The rigid-arm booster manipulator, also known as a manipulator, balance crane, balance booster, manual loadshifter (the above term is unprofessional but more popular in China), is a new type of booster device for labour-saving operations during material handling and installation. It cleverly uses the principle of force balance to enable the operator to push and pull heavy objects accordingly and to move and position them in space in a balanced manner. The weight is lifted or lowered to form a floating state and the air circuit guarantees zero operating force (in practice the operating force is judged to be less than 3kg due to machining processes and design cost control). The operating force is influenced by the weight of the workpiece. No skilled pointing operation is required for the operator to push and pull the weight by hand so that it can be correctly positioned anywhere in space.
Hard arm assisted manipulator components
A complete rigid arm assisted manipulator equipment consists of three main components: the balance crane mainframe, the gripping fixture (or manipulator) and the mounting structure.
The mainframe is the main device that enables the material (or workpiece) to float weightlessly in the air. The manipulator is the device capable of gripping the workpiece and meeting the corresponding handling and assembly requirements of the user. The mounting structure is the mechanism that supports the complete machine according to the requirements of the user's service area and site conditions.
The hard-arm power manipulator is gravity-free, precise and intuitive, easy to operate, safe and efficient and is widely used in modern industry.
Starting with the reception of raw materials and materials and continuing through every stage of the logistics process, including processing, production, storage and distribution, the hard-arm power manipulator plays a huge role.
The use of corresponding material transfer methods and means can greatly improve the transfer of heavy objects, the health and safety of the operators at the handling site, the rationality of the operation, the saving of labour, the improvement of production efficiency and the guarantee of product quality.
