How to Choose a Suitable Gantry Crane

In the construction sites of some major engineering projects, gantry cranes, as a kind of large-scale crane equipment, usually need to be purchased and installed before the start of the project. Especially after the specific project site is determined, it is necessary to select the gantry crane according to the actual site and use requirements. The following is the selection basis and precautions for gantry cranes for your reference. Selection basis of gantry crane Relevant regulations It shall comply with the related regulations of GB/T14406-1993 and GB5905-86 for general gantry cranes. Under normal circumstances, the lifting capacity is less than 50t, the span is less than 35m, and there are no special requirements for use, the single main beam type gantry crane should be selected. If the width of the gantry leg is required to be large, the working speed is high, or the heavy and long pieces are often hoisted, the double-girder gantry crane should be used. Span and cantilever length The span of the gantry crane is an important factor affecting its quality. When selecting models, the span should be minimized under the premise of meeting the equipment use conditions and the span series standards. Determination of wheelbase (1) To be able to...

How to Weld Overhead Cranes Better

For large lifting equipment, such as overhead cranes, the success of welding mainly depends on the correct guidance. There are many aspects to be checked for judging how to weld overhead cranes. Welding process factors that affect the tensile strength and bending properties of welded joints include welding method, type of base metal, number of welding electrodes, type of shielding gas, etc. If these factors change, the entire overhead crane has to re-evaluate the welding process. For the welding standards of overhead cranes, there must be correct specification guidance to avoid detours. So, the functions of overhead cranes can play a more prominent role without affecting the use of equipment. The main reasons for the welding deformation of overhead cranes Overhead cranes are hoisting equipment, which is placed horizontally over workshops, warehouses, and material yards for material hoisting. Its two ends sit on tall concrete pillars or metal support, shaped like a bridge. Overhead cranes are used widely in engineering and production, but many problems will occur during use. During the maintenance process, the welding deformation of the overhead crane is found, and the control of the deformation has become an urgent problem to be solved. Because the cross-sectional shape of...

Different Types of Crane Busbar

Introduction For electric single-girder cranes, its operation is inseparable from the application of any accessory. Take the crane busbar as an example: without its current transmission, it is difficult for the crane equipment to operate. Since the crane busbars used on different occasions are different, today, we will introduce the use and classification of crane busbars on electric single-girder cranes in detail. Three main types of crane busbar and specifications Multipole Sliding Wire The power supply safety device of multipole sliding wire is for electric hoist, electric beam type, and bridge crane: automatic detection line and automatic production line of stacker, mechanical and electrical products, mobile electric tools, and other mobile conductive equipment, as well as fixed laying of bus duct in factories, mines, workshops, and offices. The conduit safety type of multipole sliding wire is composed of high-strength engineering plastic or aluminum alloy protective shell, multi-stage conductive copper bar, collector, suspension, fixing, and other components. With the characteristics of compact design, stable performance, and safe use, it is widely used in low-current and high-frequency logistics automatic production lines and detection lines. Datasheet: Single pole sliding Wire The single pole sliding wire is a power supply system that feeds the...

Restoration and Stabilization of Fixed Column Jib Cranes

Fixed column jib cranes are one type of powerlifting and transportation equipment. The fixed column jib crane is used widely in construction, transportation, and other industries. All kinds of fixed column jib cranes are composed of numerous parts. These parts would be in wear and tear due to various factors during use. If these parts are out of use like this, everyone will feel that it is a waste. I will share with you three methods of repairing parts. Repair dimension method: The shafts and holes of the jib crane parts form elliptical and irregular shapes due to uneven wear when used. When repairing, the worn shaft or hole is machined within the allowable range of the part structure to restore the correct geometric shape or matching properties through the change of size. This method is called the repair dimension method. Insert method: Insert a new metal sleeve on the worn part of the spare part by static fit to restore the spare part to its original size. This method is called the insert method. Partial replacement, turning, and overturning repair method: When the damage occurs in one part of a component of jib cranes, the rest of the other part...

Precautions for Operation and Maintenance of Explosion-proof Crane

Factory explosion-proof crane, with the explosion-proof mark of exdiibt4\exdiict4; Dust explosion-proof crane with the explosion-proof sign dipa21tat4; Dust explosion-proof and factory explosion-proof can also be certified at the same time, which is called Double mark. The working environment of an explosion-proof crane is very harsh, and operators need to pay attention to safety points during operation: During the operation, no one is allowed around, it strictly prohibits leaving the work post without authorization, and no other person is allowed to open the machine. The hoisting command needs to be operated by skilled personnel who understand the performance of the Yellow River hoisting machinery, the signal shall be accurate during the hoisting commands, and the operation shall pause until the situation is clear. The lifting materials should keep a constant speed to be transported to the appointed place. Explosive-proof cranes strictly prohibit braking and changing direction suddenly. The lifting materials shall be more than 0.5m higher than the obstacle during the transition. The materials shall be placed gently at a low speed to prevent dumping. In case of sudden power failure during operation, the breaking point of the switch shall open immediately, and the transported objects shall be put down. An...
