Gantry Crane With Electric Hoist

 

 

Gantry Crane With Electric Hoist is a kind of lifting equipment with strong load-bearing capacity and large span. The structural characteristics of Gantry Crane With Electric Hoists make them widely used in various industrial scenarios. This type of crane adopts a double main girder design and has very high stability and load-bearing capacity. Its main beam generally adopts a box-shaped beam structure, which makes it highly safe and rigid, and is suitable for lifting operations of large and ultra-large tonnage. Compared with single-girder gantry cranes, Gantry Crane With Electric Hoists can provide a wider operating range and higher site utilization. The main girder of a Gantry Crane With Electric Hoist can extend beyond the outriggers on one or both sides to form a cantilever, thereby expanding the operating range. This design not only improves the crane's flexibility in use, but also effectively covers a wider operating area.

Main beam: The main beam is the main load-bearing component of the crane. It is usually made of steel plates welded into a box-type or truss-type structure, which bears all loads and transmits them to the outriggers and the ground.

Lifting mechanism: The lifting mechanism includes motors, reducers, drums, wire ropes, hooks and other components to realize the lifting movement of goods.

Cab: The cab is the workplace where the operator controls the crane. It is equipped with control levers or buttons for controlling various movements of the crane.

Hoist: Electric hoist is driven by an electric motor and can lift goods from the ground or a certain position to a specified height, then move them horizontally, and finally place the goods at the target location. This cyclic and intermittent movement method enables Gantry Crane With Electric Hoists to efficiently load, unload, and transport cargo in factories, warehouses, docks, and other places.

Advantages of lifting height: Due to its design advantages, the installation height of the Gantry Crane With Electric Hoist is not limited by the indoor site. It can effectively increase the lifting height to meet the shipping needs of specific occasions.

Large load-bearing capacity: With a double main beam design, its load-bearing capacity far exceeds that of a single beam design, allowing the lifting capacity to reach 20T-300T, which is suitable for heavy lifting operations, thus greatly improving the production efficiency of the enterprise.

Strong structural stability: The double-girder design can disperse the load between the two girders, effectively improving the stability and safety of the crane. The Gantry Crane With Electric Hoist has a stable structure and can withstand larger spans, making it suitable for larger-scale workplaces.

Wide range of applications: Gantry Crane With Electric Hoists are not only suitable for handling various materials, but also suitable for various working environments such as ports, construction sites, and warehouses. Able to handle a wide range of lifting needs from small parts to large equipment, it is highly adaptable.

 

 

 

Port terminal：In port terminals, Gantry Crane With Electric Hoists are mainly used for loading and unloading containers, bulk cargo, and handling the transshipment of various commodities. These cranes can carry heavy loads and adapt to long-term, high-efficiency operations, greatly improving logistics efficiency and port throughput.

Construction sites: At construction sites,Gantry Crane With Electric Hoists are used to hoist building materials such as steel bars, concrete components, etc., and to assist in the installation of large building structures. Its ability to operate in tight spaces makes it ideal for use on dense construction sites and improves the efficiency of construction projects.

Hydropower station: In hydropower stations, Gantry Crane With Electric Hoists are mainly used to open and close large gates, carry generator components weighing hundreds of tons, etc. This kind of crane usually needs to have a large lifting height and lifting capacity to adapt to the needs of special working environments.

Shipyard: In shipyards, Gantry Crane With Electric Hoists are widely used due to the need to lift large hull components and equipment. They usually have high span and lifting capacity, which can meet the demand for high-precision lifting of large components during ship construction.

 

 

 

 

 

 

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.
