Gantry Crane With Chain Hoist

 

 

Gantry Crane With Chain Hoist is a kind of lifting equipment widely used in engineering project installation and heavy cargo transportation. It is especially suitable for scenarios that require high site utilization and large operating range. The structure of Gantry Crane With Chain Hoist is relatively simple and easy to manufacture and install. Most of its main beams are deflected rail box frame structures. Since there is only one main beam, its own mass is small, but its overall stiffness is weaker than that of a double-girder crane. This design makes the Gantry Crane With Chain Hoist perform particularly well in situations where the lifting capacity does not exceed 50 tons and the span does not exceed 35 meters. When using a Gantry Crane With Chain Hoist, the operating procedures should be strictly followed, and key components such as brakes, hooks, wire ropes, and safety devices should be checked regularly to ensure that the equipment is in good working condition.

Lifting mechanism：Eliectric Hoist

 

 

Main beam: As the main load-bearing part of the crane, it is usually a horizontal beam spanning the work area, which can be a steel beam or a concrete beam. Its structure is mostly an off-rail box-shaped frame with a small mass and is suitable for situations where the lifting capacity does not exceed 50 tons.

Electric hoist: It is composed of electric hoist, reducer, wire rope, pulley and hook set. This mechanism is responsible for the lifting and lowering of cargo and is one of the core parts of the crane.

Electrical equipment: used to operate and control the operation of the crane, usually including buttons, switches, and consoles. Modern cranes are also equipped with advanced electronic control equipment to improve the convenience and safety of operation.

Crane operating mechanism: including motors, transmission shafts, reducers, wheels and other components, responsible for driving the crane to move along the ground track. This mechanism ensures that the crane can move within a wide working range and improves operating efficiency.

Simple structure: The main girder of a Gantry Crane With Chain Hoist is mostly an off-rail box frame structure with a small mass. It is suitable for situations where the lifting capacity does not exceed 50 tons. This design not only simplifies the manufacturing process, but also facilitates later maintenance and inspection.

Convenient installation: Due to its simple structure, the assembly and installation process of Gantry Crane With Chain Hoist is relatively fast, reducing construction time and labor costs. This convenience is especially important for projects that need to be put into use quickly. The equipment can be flexibly adjusted according to actual needs during the installation process to adapt to different working environments and operation requirements.

High site utilization: The Gantry Crane With Chain Hoist walks directly on the track on the ground without the need for additional support structures, effectively utilizing the site space. This design allows the equipment to achieve maximum coverage in a limited space.

 

 

Warehouse handling: In large warehouses, single-beam gantry cranes are widely used to load, unload, and carry various finished items and bulk materials, such as raw materials, finished products, etc. The site utilization rate is high and it is not hindered by ground equipment.

Container handling: Container gantry cranes are used for cargo stacking and transportation at container terminals. They can stack containers 3 to 4 levels high and 6 rows wide, speeding up the turnover of container carrying bridges or other cranes.

Hull assembly: In shipyards, Gantry Crane With Chain Hoists are used to assemble hulls on slipways. There are always two lifting trolleys running on the tracks of the upper flange and lower flange of the bridge to flip and hoist large hull segments. Its trolley operating mechanism ensures efficient hull assembly.

Heavy Material Handling: In the steel and chemical industries, Gantry Crane With Chain Hoists are used to move and lift heavy materials and products, such as steel coils, chemical containers, etc. Since there are often flammable and explosive environments in the site, it is particularly important to choose a crane with explosion-proof functions.

 

 

 

 

 

 

 

 

Material Inspection

Quality Inspection: Strict quality inspection is carried out on the purchased raw materials to ensure that they meet the design requirements and national standards.

Material Storage: Qualified materials are stored according to classification to prevent corrosion or damage.

Cutting and Forming

Steel Cutting: Use plasma cutting, laser cutting or flame cutting and other technologies to cut the steel according to the size of the design drawing.

Forming Processing: Form the steel plate through bending, rolling, welding and other processes to manufacture the main beam, end beam and other structural parts.

Welding

Component Welding: The cut and formed steel parts are welded into the main structures such as the main beam, end beam and trolley. The welding process needs to be strictly controlled to ensure the structural strength and welding quality.

Weld Inspection: Use non-destructive testing technology (such as ultrasonic testing, radiographic testing) to inspect the welds to ensure that there are no cracks or other defects.

Machining

Precision Machining: Precision machining is performed on the key components of the crane, such as wheel sets, bearing seats, pulleys, etc., to ensure their dimensional accuracy and surface quality.

Assembly of the whole machine

General assembly: On the basis of pre-assembly, the overall assembly of the crane is carried out, including the final installation of the main beam, end beam, lifting mechanism, walking mechanism, etc.

Commissioning and testing

Under dynamic conditions, the operating performance of the crane is tested, including the testing of lifting, walking, steering and other functions. The overall size of the assembled bridge crane is checked to ensure that all dimensions meet the design requirements.

Spraying and anti-corrosion treatment

Surface treatment Rust removal: Rust removal on the surface of the crane, common methods include sandblasting, pickling, etc. Primer spraying: Spray anti-corrosion primer on the treated surface to prevent metal oxidation and corrosion. Topcoat spraying Color spraying: Spray topcoat according to customer requirements or industry standards to give the crane a protective and decorative effect. Marking: After spraying, mark the crane's identification information in accordance with the specifications, such as model, rated load, etc.

Factory and installation

Packaging and transportation

Packaging protection: Protectively package the key components of the crane to prevent damage during transportation. Transportation arrangement: According to the equipment size and transportation conditions, select a suitable transportation method to transport the crane to the customer's site.

Acceptance and delivery

Customer acceptance

On-site acceptance: The customer conducts on-site acceptance of the crane according to the contract requirements and technical specifications to check the performance and quality of the equipment.

Problem rectification: If any problems are found, the manufacturer needs to rectify them in time to ensure that the equipment fully meets the customer's requirements. Delivery and use Operation training: The manufacturer usually trains the customer's operators to ensure that they can operate the crane correctly and safely.
