  Industrial Jib Cranes

  Introduction Industrial jib cranes are the new light-duty material lifting equipment that improves productivity. It is also known as a cantilever crane, swing jib crane, slewing jib crane, and workstation jib crane. With high-reliability electric hoists equipped, industrial jib cranes are more suitable for short distances, frequent use, and intensive lifting operations. So, it is relatively popular in these industrial fields such as machining, warehouse logistics, workshop production, etc. The lifting device of the industrial jib crane is suspended on the arm end or on the lifting trolley that can run along the slewing arm, and the slewing arm can turn but cannot pitch. The electric hoist runs a right and left straight line on the cantilever I-steel. The decelerating device drives the cantilever to turn, which has the characteristics of high efficiency, energy saving, trouble saving, small footprint, easy operation, and maintenance. Working principle The industrial jib crane is mainly driven by the motor drum, and the steel wire rope wrapped on the drum drives the lifting hook to carry out lifting movement, to realize the lifting of materials. Meanwhile, you can learn more about the main parts and how to choose industrial jib cranes here. Different types of...

  What are the issues of electric chain hoists that customers are most concerned about?

  How do you install the sliding wire of the electric chain hoist?  Electric chain hoists are mostly installed on U-shaped tracks. In view of this feature, the steel cable is arranged in the middle of the track and on the upper part of the I-beam. The steel cable uses q~10mm steel wire rope or round steel, and the end is fastened with a basket bolt. The sliding ring is two rings interlocked with a certain margin to avoid the scratching of the steel cable. The steering ring is two rings connected by bolts and can rotate freely. Put one end of a steering ring on the steel cable, and fix the rubber sheath wire to the lower end of the steering ring after leaving the motor lead. Put one end of multiple sliding rings on the steel cable, and then fix the rubber sheath wire in sections to the lower end of the sliding ring. The front end is connected to the motor and can move freely. The rear end is connected to the power supply. Under the traction of the motor, with the steering ring as the center, the traction steel cable moves in a straight line or circle....

  What is the advantage of the truss type gantry crane?

  Truss type gantry cranes play an indispensable role in the industrial and logistics fields due to their unique structure and multiple advantages. With the development of technology, the functions and efficiency of these lifting equipment are also constantly improving, better meeting the needs of modern industrial production. Let’s take a look at the advantages of choosing truss type gantry cranes. Large lifting capacity Truss-type gantry cranes can carry very heavy goods, and the lifting capacity can reach hundreds or even thousands of tons. Large span According to needs, truss type gantry cranes can be designed with a large span, suitable for material handling in wide venues. High efficiency The lifting trolley of the truss type gantry crane can move quickly on the beam, greatly improving the handling efficiency. Wide range of applications Whether indoors or outdoors, ports or factories, truss type gantry cranes can adapt to different working environments. Good safety The structural design of the truss gantry crane considers safety factors, and the application of modern control systems further reduces operational risks. High reliability The design and manufacture of the gantry crane follow strict standards to ensure the long-term and stable operation of the equipment. Easy maintenance The daily...

  Advantages for Single Girder Crane

  Composition of single girder crane Electric single girder cranes mainly include three kinds of operating mechanisms: hoisting operating mechanism, trolley operating mechanism, and crane running mechanism. The hoisting mechanism is mainly composed of an electric hoist, wire rope, pulley, hook, or spreader. The metal structure of an electric single girder overhead traveling crane mainly consists of two parts: the main girder and the end girder. The main girder structure is mostly a combination of I-beam and steel plate sections. It consists of a cover plate, web plate, and I-beam. The reinforcement plate, its safety, and its reliability directly affect the operational quality and working capacity of the crane. Features of single girder crane steel structure production The materials of the main steel structure (main beam, end beam) are all -B, and the materials used have material reports and corresponding certificates of conformity. Manufacturing, welding, and inspection of crane steel structures are carried out following GB/T 1306-2008. Important load-bearing butt joints are welded by a double-sided bevelling process, and appearance inspection and non-destructive testing are carried out according to regulations. All welders have relevant certificates. The main girder of all cranes adopts the whole-plate non-butt process, which cancels the butt weld...

  What’s the advantages of overhead cranes

  Overhead crane is a kind of lifting equipment, widely used in industrial and mining enterprises, the iron, and steel chemical industry, railway traffic, port terminals logistics turnover, and other departments and places. Advantages and features of the bridge cranes include: No aisle cleaning is required Overhead cranes can move to places that other equipment cannot reach. Have you ever encountered a situation where the path of a forklift truck was blocked, and you had to mobilize manpower to clear the aisle? The overhead crane can easily bypass obstacles. Suppose an independently operated push button station (which is located on its own track and therefore can be controlled from anywhere on the bridge) or wireless remote control is used as a control method. In that case, the operator can navigate around obstacles and control the crane on its own. You can arrange the factory floor according to the business style without worrying too much about the obstacles on the factory floor. Clear the floor space Your floor space is cleared because your crane’s bracket is not on the road. More often than not, your crane supplier can come up with a stand-alone column design that can be aligned with your building...

  Installation of Gantry Cranes

  Introduction Gantry cranes, also known as portal cranes, are essential lifting equipment commonly used in industrial settings. Their installation process typically consists of four main steps. Taking DejunCranes’ real case in Saudi Arabia as an example, this article will describe each step with infographics. The procedure can be a reference for single-girder gantry cranes, double-girder gantry cranes, and other types of gantry cranes. The main steps include pre-installation, track installation, assembly of the crane components, and the crucial load test. The Procedure of Gantry Crane Installation Step 1: Pre-installation Before installing a gantry crane, several crucial preparatory steps need to be undertaken including: Site Assessment: A thorough examination of the installation site is necessary to ensure its suitability for a gantry crane. Factors such as ground stability, available space, and potential obstructions must be considered. Crane Selection: Based on the site assessment, an appropriate gantry crane should be selected, taking into account factors such as load capacity, span length, and lifting height. Position Calculation: Precise calculations are essential to determine the optimal positioning of the crane within the installation site. Factors like load requirements, access points, and operational safety must be considered during this phase. Step 2: Installation of Tracks...
