15 Granty Crane

 

 

A 15 Granty Crane is a type of gantry crane that features two parallel main beams or girders. This design provides several advantages over single girder gantry cranes, making them suitable for heavy-duty applications and environments requiring higher capacity and stability.

Beam:The girder of a 15 Granty Crane refers to the two main beams or girders that are parallel to each other and form the main structural support of the crane. These girders are responsible for supporting the hoist, the carriage and any attached lifting devices, as well as the loads being lifted. The girders are connected at regular intervals with cross beams or brackets for additional stability and rigidity.

Lifting Mechanism: The lifting mechanism of a double-girder gantry crane is a hoist, usually an electric hoist, which moves along the underside of the crane's beam or girder. The lifting device moves horizontally, allowing the loads to be precisely positioned throughout the working area under the crane.

3.Control system: The control system of a 15 Granty Crane is responsible for the operation and precise control of crane movements such as lifting, lowering and horizontal movement of the load. There are different types of control systems used on 15 Granty Cranes and each has its own characteristics and advantages.

4.Hoist:The double gantry crane hoist is a critical component that allows the crane to lift and lower heavy loads. The lifting mechanism typically consists of an electric motor or sometimes a hydraulic system that rotates a drum or pulley around which the lifting cables or chains are wrapped.

5.Brake system:The brake system in a 15 Granty Crane is a vital safety feature that prevents the uncontrolled movement of the crane's hoist and trolley. It ensures that loads can be held at a specific position without drifting or moving due to forces like gravity, wind, or mechanical imbalances.

Higher load capacity: 15 Granty Cranes have a significantly higher lifting capacity compared to single girder cranes. this is because the dual beams provide additional support and stability, enabling the crane to handle heavier loads safely.

Increased stability: the dual girder design offers superior stability, especially during lifting and moving of heavy loads. this reduces the risk of instability or tipping, which is crucial when handling very heavy objects.

Longer span capability: due to their robust construction, double girder cranes can cover longer distances or spans between supports, making them suitable for large work areas such as shipyards, heavy industrial plants, and open storage facilities.

Heavy-duty construction: these cranes are built with stronger and thicker steel, providing enhanced durability and strength. they are designed to withstand the rigors of continuous operation and harsh environments.

Improved safety: with a more stable lifting platform and higher load capacities,15 Granty Cranes offer an increased level of safety for operators and surrounding personnel.

Greater flexibility: they often come with more customizable options, such as various lifting mechanisms, hoists, and trolley configurations, allowing users to tailor the crane to specific operational needs.

 

 

Industrial Manufacturing: They are used extensively in factories and manufacturing plants for moving heavy materials and products from one production stage to another. This includes the automotive, steel, and shipbuilding industries.

Construction Sites: 15 Granty Cranes are often used on construction sites to lift and place heavy materials like steel beams, concrete slabs, and other structural components.

Warehousing and Distribution Centers: In warehouses and distribution centers, these cranes can be used for loading and unloading large containers, pallets, and heavy goods.

Shipyards and Docks: In marine environments, they are crucial for loading and unloading cargo from ships, including heavy equipment and shipping containers.

Power Plants: For moving heavy turbine components and other machinery during maintenance or installation.

Railway Yards: For lifting locomotives and railcars for repair or maintenance.

Mining Operations: In mining, they can be used for handling large pieces of mining equipment and extracted materials.

Recycling Facilities: To handle large volumes of waste materials, recycling sorting processes, and transporting recyclable materials.

 

 

 

 

 

 

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.
