What Type of Cranes Are Used at Docks?

Are you familiar with cranes? In simple terms cranes are outstanding machinery found in docks. Their sole purpose is to ease movement and transportation along this infrastructure. They are the most essential equipment piece in docking areas.

Ideally the available options are numerous and this post outlines the best options in the market.

Let's get started!


Dock Crane Purpose

The primary function is to facilitate proper cargo handling, movement, and transporting of materials from ships and across the entire terminal. This is true for all dock crane versions available.

What Are the Types of Dock/Port Cranes?

‘Gantry’ is the most common categorization for most cranes. ideally, dock cranes represent massive machinery structures established a top-heavy duty gantry framing. The structure contains spreader bars usually suspended from a gantry usually for picking up containers. They perform this by latching on the containers’ corners through a unique twist lock mechanism.

After understanding what these units entail, it is only prudent to highlight the available options. In this post we will cover the following types:

Automatic Stacking (ASC) Cranes

An ASC crane is simply a completely-automated rail mounted (gantry) crane without operators. These units are nonetheless typical gantry models that use rail-mounted movement but are, however, fully automatic options that are made to boost overall productivity and efficiency.

These units are appropriately designed to function in major terminals that mandate significantly stacking density.

Heavy-duty (RTG) Cranes

A standard RTG crane is a robust machine that features rubber tires for smooth movement within a docking container yard. their principal purpose is movement and stacking of cargo containers once they are offloaded from ships. Alternatively, they work in staging containers preparing for loading operations.

These dock cranes are powered by standard diesel engines, although the current market offers fully electric models also. Control and power to the standard gantry hoist is usually routed through various cable carriers, not to mention that these cranes require operators, although there are also automated gantry crane options in the market now.

STS Cranes (Ship-to-shore)

These are by far the biggest gantry cranes in docks. STS/Quay cranes are applied in unloading and loading cargo containers from the shore or ships. While this is their primary purpose, it however confines their usage since they cannot be installed along the dock’s waterside on a rail that is spanning the entire berth length.

The High profiles: have hinged booms that ease navigation for ships while berthing

The Low profiles: comprise telescopic boom that extending from the crane over the vessels (ship) when its purpose is unloading and loading ships.

Rail mounted (RMG) Gantry Cranes

Another dock crane falling under the gantry models is the RMG option. While they are quite similar with the aforementioned RTGs, the distinguishing factor is that they use rail movement for operation as opposed to free movement through standard tires. You can find these cranes in unique double and single cantilever options as well as non-cantilever. These units are usually larger in size compared to RTGs and mandate more complex data communication provisions since they have automatic functionality and extra onboard machinery.

Finally, these cranes are robust and can handle between 3-4 containers high extending to a width of up to six rows.

Deck Crane

A deck crane is usually an offshore crane often mounted on ships’ decks. A deck crane has a compact build that takes up minimal space when loading, unloading, and even raising cargo. These cranes usually function well even in small docks even in areas with little or no infrastructure.

Floating Cranes

As the name outlines, a standard floating crane is usually a massive crane fixed on a unique floating platform used in unloading and loading containers from vessels. Ideally, the floating platforms are placed by a ship’s side and work to lift heavy items.

Final Word

As you already know, you will spot one of these machines in the docks and ports as highlighted in this post. Essentially without these machines, productivity is significantly harbored. If you want more details on the various cranes found and used in docks, our specialists are just a call away.
