1. Before using the beam spreader, firstly observe whether the beam body has any abnormal phenomena such as deformation, cracks, and welding seams. The test hoisting process must meet the load's operating route, environmental conditions, and determine the lifting and lifting positions. If the lifting is affected, it cannot be lifted. The rigging (T8 grade high-strength alloy chain) equipped with the main crane beam cannot be changed during use. Bit, knotted.
2. During the test hoisting process of the beam spreader, the load of the beam body has abnormal noise, deformation or cracks, and the test hoisting shall be stopped immediately.
3. After the test hoisting is successful, the hoisting and hoisting can be carried out. During the hoisting process, the relevant personnel must understand the identification signs and allow the operator to see the communication.
4. When lifting a load, overloading is not allowed. The beam body must be in a stable state, and the beam body cannot swing to prevent the beam body from losing balance and causing safety accidents. It is strictly prohibited to stand under the load, and it is forbidden to support the load manually.
Wire rope slings are mainly composed of metal end pieces such as main rings, shackles, (inserted) pressed wire ropes and hooks. According to different customer requirements, they can be combined into single limbs, double limbs, three limbs, four limbs wire rope slings, etc. , The metal accessories can be flexibly matched and selected according to actual use needs, convenient to use and high safety. The main rings include long rings, round rings, combined rings, etc.; connecting shackles include bow shackles, D-shaped shackles, heavy shackles, etc.; steel wire ropes include pressing and insertion knitting; metal end pieces include hooks and other metal parts; Wire rope slings can be freely combined according to customer requirements.
Pay attention to the relationship between the included angle and the tonnage during use. The larger the included angle, the lower the rated tonnage, and the included angle must not be greater than 120 degrees. The applicable temperature is between -40 and 100 degrees and shall not be exposed to corrosive gas, liquid or steam. Overload use is strictly prohibited. The hooks, rings, wire ropes and other metal parts should be connected with shackles, and the rated load should be the same. When the wire rope or metal accessories reach the scrap standard, they should be prohibited. For a complete set of slings with a storage period of more than two years, a tensile test must be carried out, and it can be used only after the inspection is qualified.
