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...

Pneumatic Air Winch – Advantage, Precaution and Maintenance

A pneumatic air winch is a kind of winch that uses compressed gas provided by an air compressor as the power source. Compared with traditional electric winches, pneumatic air winches are explosion-proof, dust-proof, and liquid splash-proof. They can better adapt to work in harsh environments. So, they are widely used in metal mines, coal mines, mining fields, and construction projects to transport mine cars and lift and pull tools, equipment, and other heavy objects in narrow lanes underground, as well as hoisting drill rods and heavy objects on offshore, land and oil field drilling platforms. Pneumatic air winches comprise pneumatic motors, reducers, brakes, clutches, drums, overload protection devices, and control valves. The traction force is 200 kg, 500 kg, 1T, 2T, 3T, and 5T, and the traction length can reach 350 meters. Related case for reference: 1.5-ton pneumatic air winch for Indonesia customer What’s the advantage of a pneumatic air winch? Pneumatic air winches are compact, fast, portable, and powerful, and can be accurately controlled when lifting heavy objects. By using thickened and strengthened reels, users can be provided with safer operation, and large reels also have a wider range of applications. The thickened base adopts a welded structure, which has...

Truss Gantry Crane

Gantry cranes can be divided into box-type and truss-frame cranes according to their structural type. Compared with box-type gantry cranes, truss-frame gantry cranes use less raw materials for steel structure and are more complex in design, but have the same support capacity as box-type gantry cranes in terms of lifting capacity. The load-bearing capacity of truss gantry cranes can be customized or adjusted according to actual needs. Generally speaking, the load-bearing capacity of truss gantry cranes ranges from a few tons to hundreds of tons. The specific load-bearing capacity depends on the design and structural strength of the truss-frame gantry crane. Which main factors will affect the load-bearing capacity of the truss gantry crane? Main beam structure: The shape, material and cross-sectional size of the main beam directly impact the load-bearing capacity. Generally, the use of stronger materials and larger cross-sectional sizes of the main beam can improve the load-bearing capacity. Hoisting mechanism: The hoisting mechanism of the truss-frame gantry crane includes a winch mechanism, an electric trolley, a wire rope, etc. Their design and configuration will also impact the load-bearing capacity. Using a more powerful hoisting mechanism can improve the load-bearing capacity. Support structure: The support structure of the flower...

HGA8+ Type Electric Stage Hoist

Stage hoist is one type of electric chain hoist, also known as the electric stage hoist, light truss hoist or self-climbing electric hoist. It is specially designed for the hoisting of light stands, speaker groups, large scenery installations and hoists for large performances and is also suitable for the hoisting of other temporary mobile occasions. Dejun HGA8+ stage hoist is a kind of light and small lifting equipment. It consists of an electric motor, a transmission mechanism, and a sprocket, and meets the international standard of production. The body shape of the stage hoist is beautiful and durable. The inner gears are all quenched at high temperatures, which increases the wear resistance and toughness of the gears. Using the most advanced international technology, fine workmanship, and gear tight. HGA8+ stage hoist advantage 1. The new side exit design ensures quiet and smooth operation of the chain. 2. The hook is forged with alloy steel and equipped with an anti-decoupling device, which can rotate 360 degrees. 3. The built-in mechanical overload safety clutch prevents damage to the hoist body and chain caused by overload or topping. 4. The lifting sprocket is made of special alloy steel, and the five-chain socket design...

Cantilever Crane Overload Protection Device

As one of China’s top 3 crane manufacturers, the cantilever crane is one of our main products. To protect the cantilever jib crane better when working, generally, we will equip the safety device on the jib crane, like an overload limiter, height lifting switch, travel limit switch, etc. The overload limiter can help clients monitor the real-time lifting weight, and when the lifting weight is over the capacity, it will sound an alarm to remind clients. However, most clients don’t know the cantilever cranes well, so they may not pay attention to the overload protection device. Now, I will introduce how to check whether the overload protection device of the cantilever crane meets the requirements. Check the safety protection device of the cantilever crane to see whether the overload protection device is sensitive, reliable, and meets the design requirements. Also, check the opening pressure of the hydraulic overload protection device, and whether the comprehensive error of the alarm and power source cut-off setting points of the mechanical, electronic, and comprehensive overload protectors meet the requirements. Finally, check the torque limiter. The torque limiter is a safety device for the boom-type crane to prevent overload and tipping. Check the sensitivity and...

BX Wall Mounted Jib Crane Installation

BX wall-mounted Jib Crane is an excellent choice for jib cranes, used in the interior of the workshop, and are characterized by space-saving, cost-saving, and flexible solutions. This article explains the installation steps and applicable working conditions of wall-mounted jib cranes, hoping this can help you to choose suitable wall-mounted jib cranes. Wall-mounted Jib Crane Installation Steps Wall Mounted Jib Cranes are designed to be mounted on walls or structural steel columns. The installation process of a wall-mounted jib crane usually includes the following steps: Step 1: Preparing the installation site Before installing a wall-mounted jib crane, it is important to make sure that the installation site is level and has enough space for the crane to rotate freely. The installation site should also be clear of any obstacles that may prevent the crane from operating. Step 2: Install the wall bracket The first step in installing a wall-mounted jib crane is to install the wall bracket itself. The wall bracket should be mounted on a wall or structural steel column that is strong enough to support the weight of the crane and the load it will lift. The bracket should also be perfectly vertical and aligned with the crane’s...
