What is the Difference Between a Harbour Portal Crane and a Gantry Crane?

Loading and unloading

• It is mainly used in ports and open-air warehouses for loading and unloading with grab or hooks.

• The lifting weight generally does not exceed 40 tons, which varies with the amplitude.

• Work speed is high, so productivity is often an important indicator.

Skipsbygging

• It is mainly used for ship platforms, floating docks and rigging sites, hull splicing, equipment rigging and other hoisting work, and hooks as spreaders.

• The maximum lifting weight is 30 tons, and the lifting weight is reduced accordingly when the amplitude is large.

Construction and installation

• It is mainly used in hydropower stations for dam watering, equipment, lifting of prefabricated parts, etc, generally with hooks.

• The lifting weight and working speed are generally between the first two types of cranes.

Factory production line

• Gantry cranes are often used to assist in the handling of heavy objects and improve production efficiency.
• Because the gantry crane has a stable structure and can withstand a large weight, it plays an important role in industrial production.

Port terminal

• Gantry cranes are used to load and unload cargo such as containers, improving cargo loading and unloading efficiency.
• Shortened the cargo turnover time and contributed to the development of the logistics industry.

Construction site

• It is used for hoisting heavy objects such as building materials, machinery, and equipment.
• Can complete the lifting task quickly and safely.

Warehousing and logistics center

• It is used for loading, unloading, stacking, and other warehouse goods operations.
• It improves the efficiency of warehousing and reduces labor costs.

Electric Hoist gantry crane
China Railway Shanghai Engineering Bureau Group North Engineering
MH10t-10.6m

Working conditions

• Suitable for subway/tunnel construction, especially for lifting operations at medium heights (about 6 meters) and limited spaces.
• Suitable for small and medium-sized material handling needs of about 5 tons.
• The lifting speed range of the electric hoist is 0.8-8m/min, which meets the lifting requirements of most medium loads.
• The operating speed is 2-20 meters/min, which is suitable for completing hoisting operations within a short moving distance to ensure smooth and safe operation.
• The design standard is based on JB/T5663-2008, which adapts to the operating needs of various working conditions.
• Can maintain good performance in various climatic conditions.

Fordel

• Simple structure, easy to install and operate.
• Strong adaptability, suitable for a variety of indoor and outdoor venues.
• Cost-effective, affordable, suitable for small and medium-sized enterprises.
• Safe and reliable, equipped with safety measures such as buffer device, stroke limit protection and overload protection.
• Energy saving and environmental protection, electric drive, low energy consumption, low noise, green and environmentally friendly.

MG45T-35m

Working conditions

• The rail mounted container gantry crane is mainly used in port terminals, railway cargo yards and logistics centers, and is specially used for container loading, unloading and handling.
• Its design is suitable for long-distance and long-span operations, and can efficiently handle the transshipment of containers.
• The lifting weight is 45 tons, which can meet the handling needs of standard containers, including fully loaded 20-foot and 40-foot containers.
• The lifting speed is 12 (full load) m/min, 20 (no load) m/min, and the operating speed of small cars and carts is 50m/min, which can complete the lifting and transshipment tasks of containers in a short time, and adapt to high-intensity and high-frequency loading and unloading operations.

Fordel

• Efficient loading and unloading: rapid lifting and movement to improve the efficiency of container transportation.
• Long-span operation: suitable for wide cargo yards and reduce the frequency of equipment movement.
• Stable structure: double beam design to ensure the stability of heavy-duty and high-speed operations.
• Safe and reliable: equipped with safety devices to ensure safe operation.
• Strong adaptability: adapt to the operating needs of various weather and environmental conditions.

Guangzhou Changzhou Island 60t havneportalkran

Working conditions：

• Four link portal harbour cranes are mainly used in ports, docks, depots and other occasions, and are suitable for loading and unloading heavy cargo.
• Its structural design is suitable for handling bulk cargo, containers, and other heavy materials at seaside or inland ports.
• The working radius of the crane ranges from 15 meters to 55 meters, covering a wide operating area, suitable for handling a variety of different sizes and weights of cargo.
• The lifting height of the crane can reach 50 meters, which is suitable for hoisting operations on towering ships or elevated facilities.

Advantage：

• A wide range of operations, which can effectively cover the cargo handling area of large ships.
• Able to handle heavy cargo and large containers, and adapt to high-intensity operating requirements.
• The four-link structure design provides greater operating flexibility and can maintain stable operating performance under different operating radii.
• The harbour portal crane has a sturdy structure, which provides good wind resistance and overturning resistance to ensure the safety of operation under severe weather conditions.
• Equipped with an anti-swing system, which is more stable during operation, reduces the shaking and tilting of the goods, and is suitable for high-precision operations.
• Complex operations can usually be performed in a smaller work area.

Guangzhou Pearl River Wharf Type 4073 Single Boom Portal kran

Working conditions：

• Single Boom Portal cranes are mainly used in ports, docks, depots and other occasions, especially suitable for loading and unloading heavy cargo and bulk cargo.
• Its design is suitable for occasions where long boom extension is required, such as cargo loading and unloading of large ships.
• The working radius of the crane ranges from 20 meters to 73 meters, which can cover a very wide operating area and is suitable for the loading and unloading needs of large ships.
• The lifting height of the crane can reach 56 meters, which is suitable for hoisting operations on towering ships or elevated facilities.

Advantage：

• Can cover a wider working area.
• The single-boom design enables the crane to have good flexibility under different operating radii and can accurately lift the goods to the designated location.
• It is more suitable for long-distance and large-scale operations, especially in the operation of relatively empty docks or large ships.
• Suitable for large ports that require fast and efficient loading and unloading, and can complete the transshipment of a large number of goods in a short time.
• The amplitude and lifting height of the single boom portal crane are greater than that of the four link portal harbour crane.
