Grab Ship Unloader

Product Introduction

Grab ship unloader is a kind of efficient mechanical equipment specially for bulk cargo loading and unloading. Its structural design is complex and sophisticated, aiming to meet the needs of fast, safe and efficient operation.

First, the arm system is one of the core parts of the grab ship unloader, responsible for providing sufficient working range. The arm is usually made of high-strength steel, with good rigidity and stability to ensure that it will not deform or shake during large-scale movement. The arm connects to the fuselage through a hinge, and can be hydraulically or electrically driven to achieve variable amplitude.

Secondly, grab device is the part that directly contacts the cargo. According to different cargo types (such as coal, ore, grain, etc.), different types of grabs can be selected, such as double-rope grabs or multi-petal grabs. The design of the grab should not only consider its grabbing efficiency, but also ensure that the cargo will not spill during the lifting process. Grab usually has an automatic opening and closing mechanism, which controls its opening and closing action through a wire rope or a hydraulic cylinder.

Third, lifting mechanism is responsible for lifting and lowering the grab bucket, which includes components such as winches, wire ropes and pulley blocks.

In addition, the travel mechanism enables the whole machine to move on the track so as to cover the entire length of the quay and reach different locations of the ship. The travel mechanism is usually driven by an electric motor and cooperates with a gear transmission system to achieve smooth and fast movement. In addition, in order to ensure the stability and safety of the equipment on the track, the travel mechanism is also equipped with anti-skid devices and limit switches.

Application

Coal terminal: Grab ship unloaders are widely in coal loading and unloading operations, and can quickly and efficiently unload coal from cargo ships to storage yards or transport vehicles.

Ore terminal: Mineral resources such as iron ore and copper ore are usually transported by large cargo ships. Grab ship unloaders can quickly and accurately unload these ores from ships for subsequent transshipment or storage.

Grain terminal: Agricultural products such as grains and soybeans occupy an important position in international trade. Grab ship unloaders can quickly complete loading and unloading tasks while ensuring the integrity of the goods.

Railway freight station: In some large railway freight stations, grab ship unloaders are to handle bulk cargo such as coal and ore transported by rail to ensure that the goods can be quickly transferred to the destination.

Inland ports and multimodal transport hubs: Inland ports and multimodal transport hubs are also important application scenarios for grab ship unloaders. They can effectively connect water, rail and road transportation to achieve efficient cargo distribution.

Mines: At the mine’s export dock or transshipment point, grab ship unloaders are used to load mined ore onto ships, or to unload imported machinery and materials into the mine.
