Choose the crane spreader should be based on the nature of the goods, packaging, shape, weight and other specific circumstances, in order to meet the requirements of the operation of the principle of choice, there are the following essential conditions: have sufficient strength, safety load to adapt to the weight of the goods; hanging The goods are safe and reliable, they will not dislocate; they will not damage the goods; they are easy to pick and hang, and the loading and unloading of goods is simple and easy. Choosing the right crane spreader and rigging is very important for preventing cargo damage, avoiding accidents at work, and improving loading and unloading efficiency. It is necessary to educate workers who have picked hooks to attach importance to the selection of spreader rigging. The strength of the crane slings depends on the material and the method of making them. For strops such as ropes, nylon ropes, and steel ropes, it is necessary to pay attention to check the joint status of the joints, whether there are bends, kinks, and toughness conditions that affect the strength of the spreaders. When selecting a network or cargo pocket, check the strength of the hoisting system as a priority. If the hoisting system is not strong enough to break, the danger is greatest. Pay attention to the shape of the cross-section of the hook head of the hook attached to the vehicle. Sharp edges make it easy to cut the rig and cause an accident. The selection of any spreader must first be considered in accordance with the characteristics of the work cargo. Another method of selecting wire ropes is to use products manufactured by professional spreaders. Xugong truck crane, liberated truck crane, Dongfeng truck crane, Cheng Li truck crane can be divided into straight arm type truck crane, folding arm truck crane, according to the tonnage can be divided into 2 tons of crane, 3.2 tons truck crane, 4 tons truck crane, 5 tons truck crane, 6.3 tons truck crane, 8 tons truck crane, 10 tons truck crane, 12 tons truck crane, 16 tons truck crane, etc. With the special requirements of customers with the car crane, with the car crane Co., Ltd. can also be designed and modified according to user requirements. There are several types of spreaders used in loading and unloading operations to suit different types of goods: 1, fiber rope spreader The lengths of the brown rope and the nylon rope are cut to an appropriate length, and the loop rope buckle is formed by plugging and knitting, which can be used for loading and unloading various miscellaneous goods and bagged goods. In general, more than 30 millimeters in diameter are used. Compared with steel wire ropes with the same diameter, the brown rope clasps have a small pulling force and are easy to break. Therefore, they must be carefully selected when using them, and carefully check for flaws such as broken stocks to prevent sudden breaks in the truck lifting work, resulting in work-related accidents. In addition, when hoisting heavy box cargo or angular steel using a stringer, the underlay must be filled at the corner of the cargo and the spreader. Otherwise, it must not be used. Chemical fiber ropes are stronger than brown ropes and have many advantages. Therefore, they have gradually replaced palm lines and are widely used. But its fatal weakness is that it will damage the material after being heated by friction. In the loading and unloading operation of the truck, it should be avoided to force the chemical fiber ropes under the cargo to forcefully pull out or directly penetrate the hoisting eye to lift. 2, steel wire rope spreader Wire rope slings are generally made of soft steel wire ropes, which are knit by twisting the two ends into a hammer or by knitting a rope into a loop. There are also slings installed with hooks at one or both ends. Depending on the loading and unloading operation of the loader, the structure and dimensions of the wire rope slings used are also different. However, the wire ropes commonly used as slings are usually 16 to 24 mm in diameter. 3, network Also known as the net pocket, it is a mesh rig made of various fiber ropes such as steel wire ropes or nylon ropes, and can be roughly classified into a general cargo network and a bulk cargo network depending on the purpose. However, when loading or unloading vulnerable goods or unstably packed cargo is directly carried by the network, it is easy to squeeze and damage the cargo. Therefore, it is often adopted to pave the board on the network or insert a support frame in the middle of the network crane to prevent the goods from being squeezed. Pressure friction causes damage. 4, canvas cargo pocket When loading and unloading goods in paper bags or vinyl bags, the use of a general network is liable to cause damage. Therefore, it is common to use canvas cargo pockets when loading and unloading bags of cement and flour, also known as powder cargo pockets. 5, sling The sling is a flat strap rig that, similar to the canvas pocket described above, can be used in paper bags and vinyl plastic bags to prevent cargo damage. 6, pallet spreader This is an on-board crane spreader that can stack bags of cargo, etc., on top of the pallet. With the gradual expansion of the use of forklift trucks in the loading and unloading operations of ships, carton packaging, such as fruit and frozen fruits and frozen fish and meat, has also been heavily used for loading and unloading operations. In order to prevent the occurrence of cargo roll-off accidents during the rigging operation, the use of special hangers or hanging net covers is generally adopted. 7, hook clamp spreader This is a truck-mounted spreader made of various pairs of metal hook clamps installed on various fiber ropes, steel ropes, and chains to meet the needs of hanging goods. According to the shape and weight of different types of goods, their structural patterns are also different. The main ones are the following types: drum spreaders; big bucket spreaders; tobacco vat spreaders; steel pipe hooks; steel plate clamps (commonly known as steel clamps); cotton hooks; seal corner connect injection machine Ningbo Huacheng Rubber And Plastic Machinery Co., Ltd , https://www.hacenmachinery.com
