③ balance crane known as the balance hanging, Hulin cantilever crane, it is the use of four-bar linkage principle makes load and the counterweight constitute a balanced system, you can use a variety of spreader flexible and easily lifting loads in three-dimensional space. Balanced crane lightweight and flexible, and is an ideal lifting equipment lifting small items, single cantilever crane, is widely used in factory floor machine loading and unloading, inter-process, automatic line, production line of the workpiece, sand box lifting, zero member assembly, as well as railway stations, docks, warehouses and other occasions safe use cantilever crane cantilever crane needed to detect what is developed in recent years, the production of advanced lifting equipment, compact, lightweight, easy to operate, a wide range of applications, from the weight of large, economic and durable, get a lot of users of all ages. However, for safety reasons, it needs to be tested before use to test their operational performance and other aspects of eligibility, forklift jib cranes, generally detected at several projects. 1, compliance with the provisions of the design drawings and technical documents. 2, the electrical wiring is installed correctly, the motion controller is normal. 3, riveting, welding quality metal structure is good, the structure is of sufficient strength and stiffness. 4, each braking device, limiting device, the safety devices are reliable, action is sensitive and accurate. 5 agencies in the mechanical transmission is smooth and sounds normal. 6, electrical components at work temperature is normal. 7, centralized lubrication oil passage is smooth. Operation and inspection of equipment before the experiment. To protect the safety of running test, carried out smoothly, must be carefully checked for jib cranes crane equipment before the experiment, and fully prepared for the test well. Such as jib cranes lifting equipment in use, safety is the most important, do not wait until an accident only to solve, preferably before use to detect good, be prepared to reduce the occurrence of accidents, more safe.
