  Overhead Crane Busbar System

  As the application of bridge cranes becomes more and more extensive, users pay more and more attention to the safety and performance of the power supply. The previous bridge cranes used exposed-angle iron and copper bar conductors as the crane busbar for the power supply. Although this power supply method can be used, it is not ideal for performance and safety. The crane busbar is also known as sliding contact lines. The safety sliding contact lines used in the market mainly include the following types: seamless sliding contact lines, tubular sliding contact lines, and single pole sliding contact lines.  Seamless sliding contact line The seamless trolley line of the bridge crane uses oxygen-free copper to transmit power, which has double the conductivity, good contact, easy installation, replacement, and transportation, does not easily wear and damage the trolley line, and prolongs the service life. The seamless copper core is closely combined with the plastic shell, which prevents poor contact caused by vibration. Compared with traditional power supply methods, it is safer. Because of its safety, convenience, and high cost performance, many users love it. Tubular sliding contact line The tubular trolley line of the bridge crane is generally 4 meters long...

  Single Girder Overhead Cranes Run-in Period and Troubleshooting Examples of Common Faults

  Usually, a new single-girder crane has a trial run period before it is officially used, which is also called a “run-in period” in the industry. Cranes are generally required to have a running-in time of 60 hours after leaving the site. The purpose of running-in period is to ensure the normal operation of the single-girder crane, reduce the incidence of failure, and prolong the service life and work efficiency. In reality, many users ignore the running-in period when using single-girder cranes and use them directly, which may often lead to frequent failures, seriously shorten the service life of the machine, and naturally affect the progress of the project. So what happens during the running-in period of the single-girder crane? Single girder overhead crane fast wear The assembly and processing of the parts of the new machine will be affected. The initial friction is high, and the pressure on the surface is uneven. The friction will be even greater during the operation of the machine, which will often produce a lot of metal debris and accelerate the wear of the surface of the parts. If the load is operated at this time, it may directly lead to damage to the parts....

  What is the standardized operating procedure for mobile rubber tyred gantry crane?

  The mobile rubber tyred gantry crane is a full-slewing crane with a lifting mechanism installed on the chassis composed of heavy-duty tires and axles. Its upper structure is basically the same as that of the crawler crane. In order to ensure the stability of the fuselage during installation, The crane has four telescopic outriggers. On flat ground, the outriggers can be used for hoisting with a small lifting capacity and driving at low speed. The upper part is the lifting operation part, which is equipped with a boom, hoisting mechanism, luffing mechanism, counterweight, turntable, etc.; the lower part is the supporting and walking part. The connection between getting on and off the car is connected by a slewing bearing. When hoisting, it is generally necessary to lower the outriggers, increase the supporting surface, and level the fuselage to ensure the stability of the crane. In order to prevent accidents at the use site, the operation of the crane must follow the operating procedures of the mobile rubber tyred gantry crane: Operators of rubber tyred gantry cranes need to pass standard training for specific types of equipment and obtain corresponding certificates. Before getting on the machine, it is necessary to understand...

  Single Girder Gantry Crane Dismantling Scheme

  Single girder gantry crane is a kind of common lifting machinery, which belongs to a kind of gantry crane, and is widely used in the fields of industrial production and logistics transportation. Due to the problem of project turnover or enterprise relocation, you may face the problem of dismantling and installing gantry crane equipment. Today, the professional of the crane manufacturer will give you a brief explanation of the content of the dismantling single beam frame crane plan. Principles of single girder gantry crane demolition work Safety first: Before dismantling the single girder gantry crane, the safety of the workplace must be ensured. Demolition personnel must receive professional training, abide by safe operating procedures, and wear safety helmets and protective gloves. Minimize loss as much as possible: During the demolition process, the loss of equipment must be minimized. This can be achieved through correct disassembly methods and reasonable protection measures. For example, a crane can be used to lift equipment instead of moving it by hand. Principles of environmental protection: During the demolition process, the principles of environmental protection must be followed to minimize the impact on the environment. Waste and hazardous substances generated during demolition must be disposed of...

  Which working environment is the European overhead crane suitable for?

  Firstly, please understand some information about European cranes. European overhead crane has light weight, compact structure, and low energy consumption. A trolley and a lifting mechanism are installed on the overhead frame. The trolley can run forward and backward, and the trolley can run with other mechanisms to realize the transportation of materials and objects in three-dimensional space. European-style crane adopting a unique design concept, it has the characteristics of small size, light weight, and small wheel pressure. Compared with traditional cranes, the limit distance from the hook to the wall is small, and the headroom is low. Keli cranes can work closer to the front, and the lifting height is higher, which actually increases the effective working space of the existing factory building. Because the crane has the characteristics of light weight, and small wheel pressure; the new workshop space can be designed to be smaller and more fully functional. A smaller facility means significant savings in the initial construction investment, as well as long-term heating, air conditioning, and other maintenance costs. The performance of the European crane is reliable, the failure rate is low, and the cost of use and subsequent maintenance is reduced. Because European crane has the characteristics...

  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...
