• Belt shiploader: Belt shiploaders are equipped with large, continuous conveyor belts that transport bulk materials from the terminal to the ship. They are commonly used for loading bulk commodities like coal, iron ore, and agricultural products. Belt shiploaders provide high loading rates and can be adjusted in length and height to suit different ship sizes and loading configurations.
• Mobile harbor crane shiploader: Mobile harbor crane shiploaders combine the versatility of mobile harbor cranes with specialized loading attachments (e.g., grabs, buckets, or containers). They are suitable for various cargo types, including containers, bulk, and general cargo. Mobile harbor crane shiploaders offer flexibility and adaptability, making them ideal for ports with diverse cargo operations.
• Rail-mounted shiploader: Rail-mounted shiploaders are installed on railway tracks, allowing them to move along the track's length. They are beneficial for loading bulk materials in large quantities or specialized applications, such as loading hazardous materials or temperature-sensitive cargo. Rail-mounted shiploaders provide precise control and high loading efficiency, minimizing product loss and contamination risks.

Specifications and maintenance of mobile shiploader

The mobile shiploader has various specifications depending on the type and application. Here are some general ones:

• Loading Rate:

  Mobile shiploaders have different loading rates. The loading rate is the maximum capacity at which the shiploader can load cargo onto the ship. The loading rate is measured in tons per hour (TPH). Mobile shiploaders with higher loading rates are suitable for applications where loading needs to be done quickly, such as coal loading or grain loading. A typical loading rate for a mobile shiploader is between 500 to 2000 tons per hour.

• Outreach:

  Mobile shiploaders have different outreach specifications. Outreach refers to the maximum distance the shiploader can extend beyond the quayside to load ships. A shiploader with a larger outreach can accommodate larger vessels or allow for more flexibility in ship positioning. The outreach is typically between 30 to 60 meters.

• Power Supply:

  Mobile shiploaders are powered by different power supply systems. Some shiploaders are powered by diesel engines, while others use electric motors. Shiploaders powered by diesel engines offer more mobility and flexibility, as they do not rely on external power sources. However, those powered by electric motors are suitable for applications that require higher loading rates and lower emissions.

• Hopper Size:

  Mobile shiploaders come in different hopper sizes. The hopper is the cargo collection and transfer point to the ship. The size of the hopper affects the loading efficiency, as larger hoppers can hold more cargo and reduce loading times. The hopper size varies based on the specific application and loading requirements. Typical hopper sizes range from 20 to 100 cubic meters or more.

Here are some general maintenance requirements for mobile shiploaders:

• Regular Inspection:

  Mobile shiploader operators and maintainers should conduct regular inspections of the equipment. The inspections help identify any potential issues or wear and tear that need to be addressed. The inspections should cover all components, including the loading arms, drives, structures, and electrical systems.
