Cargo grab deck crane, directly translated as 'Cargo Grab Deck Crane', is a lifting equipment specially installed on the deck of a ship for grabbing and handling bulk cargo. Equipped with a grab, it can efficiently grab granular or lumpy cargoes such as coal, ore, grain, etc. and transfer them from the cargo hold or barge to the designated position on the ship or shore.
Working Principle
The working principle of the Cargo Grab Deck Crane is relatively simple. Firstly, the grab is placed on the material pile with the opening downwards. Then, through hydraulic or mechanical drive, the closing mechanism is actuated to close the bucket and grab a certain amount of material. Next, the crane lifts the grab to a specified height and moves it horizontally to the discharge position. Finally, the bucket is opened and the material in the grab is discharged.
Structural features
Base: The base is usually fixed on the deck of the ship as the support of the whole crane.
Column: The column connects the base and the slewing mechanism to provide vertical support for the crane.
Slewing mechanism: The slewing mechanism enables the crane to rotate around the column to extend the operating range.
Lifting mechanism: The lifting mechanism is responsible for lifting and lowering the grab.
Grab: The grab is the core component of the crane and is used for grabbing and handling materials.
Hydraulic system or mechanical transmission system: to provide power to drive the action of the mechanism.
Control system: Control the various movements of the crane to ensure safe and reliable operation.
Functional characteristics
Efficient: Cargo grab deck cranes grab and handle materials quickly and efficiently, greatly reducing the loading and unloading time.
Flexible: can be adapted to various shapes and sizes of the cargo hold, a wide range of operations.
Safety: Equipped with a variety of safety protection devices to ensure the safety of operating personnel and equipment.
High reliability: simple structure, easy maintenance, high reliability.
Application areas
Harbours: used for loading and unloading coal, ore, grain and other bulk cargo.
Inland navigation: for the transfer of goods between barges.
Marine engineering: used for material supply and equipment installation on offshore platforms.
Summary
As an efficient and reliable lifting equipment, cargo grab deck crane plays an important role in the field of port and shipping. It not only improves operational efficiency, but also reduces labour intensity and improves the operating environment. With the continuous progress of technology, the performance of cargo grab deck cranes will be further improved to provide more efficient and convenient services for material handling.
