Balance lifting is a kind of lifting device with balance bar system as its main structural feature. The use of servo drive system of the balance crane is called servo balance crane. The lifting device is mainly composed of column, head frame, arm and transmission part, with compact structure and beautiful shape. Its main characteristic is to use the rod system balance principle and enlarge the ruler principle, the operator only needs to use a few kilograms of force, can make tens to thousands of kilograms of heavy objects in up and down, before and after, the horizontal three-dimensional space light freely hoisting, and reliable operation, is the production line, machine tools and other equipment on the workpiece, the ideal hoisting device. Its successful development has filled a gap in our country, belongs to the domestic initiative.
Since 1974 successfully developed the first 100 – kilogram mechanical balance machine, for the balance machine series product development has laid a good theoretical calculation and actual production base, from the 70 s to the early 80 s, has accomplished covers in mechanical, hydraulic and pneumatic transmission way, rated carrying load of 50, 100, 200, 300, 500, 800, 1000 kilograms of balance machine series products and its derived products, and form a batch production.
Handling heavy objects in the factory workshop is often the use of cranes, electric hoists, industrial manipulators, etc. But for frequent hoisting and short operation time, such as machine tool up and down the workpiece, assembly work hoisting parts, fixed point work on the assembly line and so on; For the more precise positioning requirements of the occasion, such as the core in the casting, the box, and so on, general lifting equipment is usually not applicable, industrial manipulator is more used in the production of automatic line or a single repeated operation, and the cost is higher, at present, the general workshop use less. In recent 20 years, a new type of fixed-point lifting equipment “Balance Arm” has appeared, which is suitable for frequent fixed-point lifting of tens to hundreds of kilograms of workpieces. Its structure is simple, the operation is flexible, especially suitable for one person to operate, intuitive feeling is good, the manufacture, the maintenance is convenient, in the production has been gradually promoted, welcomed by workers.
