  The electric single-girder eot crane uses a fixed electric hoist installed on the main beam of the eot crane as the operating mechanism of the trolley. The single eot crane product has simple structure, light weight, and cheap price. It is mainly used for general lifting operations in machinery manufacturing workshops, warehouses, assembly, and hydropower station maintenance. What are the main components of the LD type electric single-girder eot crane? Main beam of single girder eot crane The LD type electric single-girder bridge crane adopts a three-girder structure. The main beam and end beam are connected to the end beam through high-strength bolts. Buffer blocks are provided on both sides of the main beam to prevent the running mechanism from reaching the extreme position. Rising institution of single girder eot crane The lifting mechanism uses an electric hoist, which is designed and manufactured by professional manufacturers. The structural features are described in detail in the electric hoist manual. Cart of single girder bridge crane The operating mechanism of the LD electric single-girder eot crane adopts four-wheel drive. The drive motors are two conical brake motors. The number of driving wheels is half of the total number of wheels. Electronic system...

  Maintenance of Overhead Crane and Gantry Crane

  Crane equipment also needs maintenance in the process of use. The maintenance of cranes should start from six aspects, namely, sufficient oil, sufficient water, sufficient air, and frequent inspection of fastening parts. The following is a detailed introduction to the maintenance measures and classification of crane equipment. Crane Equipment Maintenance Measures Feet: the feet of oil, the feet of water, and the feet of air If the supply of diesel, gasoline, and air is not timely or interrupted, there will be difficulties in starting, poor combustion, power drop, and the crane engine cannot operate normally. If the oil supply is insufficient or interrupted, the engine will suffer from poor lubrication, serious body wear, and even burnt tiles. If the cooling water is insufficient, the machine temperature will be too high, the power will drop, the wear will increase, and the service life will be reduced. Inspection: check the fastening parts frequently Due to the influence of vibration, shock, and uneven load during the use of diesel engines and gasoline engines, bolts and nuts are easy to loosen. In addition, the adjustment bolts of each part must be checked to avoid accidents that damage the body due to looseness. Purification: oil...

  Grab for Crane

  A grab bucket is a lifting device that relies on the opening and closing of two left and right combination buckets or multiple jaw plates to grab and unload materials. It is a pickup device underneath cranes for loading and unloading various goods. Grab bucket models There are various types of grab cranes, including gantry grab cranes and bridge grab cranes. According to the specific gravity of the grabbed material, various types of grabs are divided into light grabs, medium grabs, heavy grabs, and super heavy grabs. According to the grab of the crane, it can be divided into single rope suspension grab, two rope grab, four rope grab, four rope grab type grab, electric motor grab, stainless steel grab, hydraulic multi flap grab, scissor grab buckets, log grabs, and electro-hydraulic grabs. How to choose a suitable crane grab bucket? Before selecting the grab type, first confirm the working environment of the grab crane, the object to be grabbed, the cubic number of the object to be grabbed at one time, the specific gravity of the material, and the tonnage of the grab crane used with the grab. Then judge which type of grab bucket to use based on the...

  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...
