Types, use and purchase tips of crane hooks

As heavy mechanical equipment, a crane is a material lifting tool, and the crane hook is an important part of the crane to carry goods, which plays a very good role in the lifting and handling of heavy objects in the operation. We will give you a detailed introduction to the types of crane hooks, and use and purchase tips for crane hooks. What are the types of crane hooks? Generally speaking, according to the shape, the crane hook of the overhead crane and gantry crane can be divided into a single hook and a double hook. If it is from the manufacturing method, it can be divided into forged hook and sheet hook. The single hook is easy to manufacture and use, and is often used for lifting objects with relatively light weight; while the double hook weighs a lot, and is generally used for lifting objects with heavy weight. Generally, forged single hooks are mainly used for lifting cranes below 30T, double hooks are used for lifting cranes of 50T-100T; sheet single hooks are used for lifting 75T-350T cranes, and double hooks are used for lifting cranes above 100T. Let’s take a look at the cross-sectional shape of...

The Difference Between Insulated Bridge Cranes and Ordinary Bridge Cranes

Introduction Bridge cranes are an essential part of many industries, used for the movement of heavy loads across the shop floor or from one workstation to another. There are different types of bridge cranes available in the market, each serving a unique purpose. In this article, we will compare the difference between insulated bridge cranes and common bridge cranes. Insulated Bridge Cranes An insulated bridge crane is a type of bridge crane that comes with insulated features. It is designed to be used in industries with a high risk of electric shock, which could lead to injuries or fatalities. The crane is equipped with insulated components such as motors, cables, and controls, which protect the crane operator or any other personnel working within the area. The main difference between an insulated bridge crane and an ordinary bridge crane is the level of safety it offers. In any industry where electric shock is likely to occur, the use of an insulated bridge crane is mandatory. These cranes undergo rigorous testing to ensure they meet the safety standards required. Another significant difference is the type of materials used in making the crane. Insulated bridge cranes are manufactured using special insulating materials, which...

Grab Bucket Type, Structure and Application of Grab Cranes

The new type of crane equipment with the grab bucket as the spreader can perform operations such as unloading, stacking, reversing, retrieving, and loading materials during the raw material preparation process. With its excellent performance, the grab crane has been widely used in the hoisting of general cargo in various factories and mines, and it is equipped with a special spreader such as a grab for special operations. Grab bucket type of grab crane In the actual operation process, in order to ensure that the grab bucket of the grab crane is full of materials, the basic conditions that should be met are suitable bucket shape, basic size, and sufficient self-weight. According to the material’s characteristics, grabs can be divided into four basic types: light, medium, heavy, and extra heavy. In comparison, the self-weight of the medium-sized grab bucket is about equal to the weight of the material, the self-weight of the light-duty grab bucket is smaller, and the self-weight of the heavy-duty grab bucket is larger. For different types of grabs, corresponding parameters and structural types should be selected. For example, double-jaw grabs are suitable for grabbing granular materials and powder materials. Toothed. When the grab is used to...

Installation steps of wire rope hoists

The wire rope electric hoist is a small lifting equipment. The wire rope electric hoist has the advantages of compact structure, light weight, small size, strong versatility of parts, and convenient operation. Wire rope electric hoist installation is an important step before use. On the basis of understanding the operating instructions of the wire rope electric hoist, please also pay attention to the following items: 1. Please memorise the contents of the instruction manual and the nameplate before operating. 2. Please adjust the upper and lower limit stop blocks before lifting the object. 3. Please confirm whether the brake condition is reliable before use. 4. If the wire rope of the wire rope hoist is found to have the abnormal conditions (bending, deformation, corrosion, etc) before use, never operate it. 5. The degree of fracture of the wire rope exceeds the specified requirements, and the amount of wear is large. 6. Please use a 500 V megger to check the insulation resistance of the motor and the control box before installation and use. The cold resistance at room temperature should be greater than 5 MΩ before use. 7. Please never use the wire rope electric chain hoist to lift objects...

Bridge Crane and Gantry Crane Overhaul of Oil Leakage of Reducer

Bridge crane and gantry crane are our main product, and the overhaul of oil leakage of reducer of gantry crane and bridge crane is very important. Check measures to prevent oil spills of bridge crane and gantry crane. And some other answers to frequently asked questions about bridge and door cranes. Overhaul of Oil Leakage of Reducer of Gantry Crane and Bridge Crane Maintenance of oil leakage ① The oil leakage of the reducer usually occurs in the following places: a. The joint surface of the reducer box is especially serious for the vertical reducer. b. The shaft end cover of each shaft of the reducer, especially the shaft hole of the through cover. c. The flat cover of the observation hole. ②Analysis of the causes of oil leakage: a. The joint surface of the box body is processed rough, and the joint is not tight. b. The box is deformed, and the joint surface and the bearing hole change accordingly, forming a gap. c. The gap between the bearing cover and the bearing hole is too large, the oil return channel in the through cover is blocked, and the sealing ring of the shaft and the through cover is aging and...

How to Increase the Service Life of a Single Girder Crane?

The many advantages of single girder cranes make them widely used in various industries, reduce labour intensity, and greatly reduce the difficulty of work. However, due to differences in operation and maintenance, the service life of single-girder cranes will also vary. So how can we prolong the service life of the single girder crane? If the service life of the single girder cranes can be increased, the capital investment and asset cost of the enterprise can be saved. In order to increase the service life of the single beam crane, we should pay more attention to the following aspects: Do a good job in the lubrication and maintenance of the single beam crane. During the operation of the equipment, if the grease cannot be supplied, it will damage the equipment and reduce the service life if it is operated again. Lubricating positions include: rolling bearings, hook rollers, fixed rollers, and other rolling bearings, gear couplings, braking systems and their computer operating systems, reducer gear shafts, and core movable pins of galvanized steel wire ropes. Check the tightening position frequently. If the anchor screws and nuts are loose, it is easy to cause a safety accident that damages the human body....
