To Know the Gantry Cranes Deeply: Help Us Choose the Suitable One

May 25, 2024

Gantry cranes are a variety of an overhead crane distinguished by a hoist mounted onto a trolley, allowing horizontal traversal via rails, typically fitted on either a mono or dual beam structure. Its main roles are lifting and transporting substantial weights for us. Usually, we use them in expansive outdoor environments, because almost all gantry cranes have a large footprint. It is not difficult for us to see them in the shipyards, railway yards, and building sites.

You may curious that these gantry cranes have so unique design and robust construction can do what for us. And then I will answer this question for you.

First of all, they can move objects that are too heavy for our ability, too large for other machinery, or in locations where other lifting methods may be impractical or nonviable.

Secondly, due to their sturdy structure, they can suit various working conditions and environments. They not only can work on the rugged terrain of a construction site, but also it can satisfy the demands of a busy shipyard.

The different type of gantry cranes

There have many types gantry cranes in the market, but today we will focus on introducing the semi gantry crane and rubber tired gantry crane to you.

The semi gantry crane

A semi gantry crane is a type of crane that has one end supported by a structure, such as a building or a wall, while the other end is supported by wheels that run on a track or rail.

The component of semi gantry crane

  • Principal Beam: The primary horizontal beam that shoulders the weight of the hoist and trolley.
  • Terminal Carriage: The wheel-based mechanism enabling the crane to traverse along the designated track.
  • Hoisting Apparatus: The mechanism responsible for elevating and descending the load.
  • Trolley Framework: The setup that facilitates horizontal movement of the hoist along the core girder.
  • Command System: The setup designed to operate and govern the function of the crane.

The advantages of semi gantry crane

  • Versatility: Capable of handling an extensive variety of loads and materials. This adaptability enables operation across multiple sectors, handling different types of goods, thus eliminating the need for multiple specialty machines. This universality ultimately saves time, reduces redundancy, and optimizes productivity.
  • Space-saving: Due to its compact design compared to a full gantry crane, it effectively utilizes space. This compactness is a boon, especially in space-restricted sites, wherein the crane can perform its duties without compromising other operations. This efficient use of space can also potentially reduce rental or property costs.
  • Cost-effectiveness: The crane’s initial investment and operational costs are lower compared to other lifting equipment. This affordability makes it more accessible to various businesses, even smaller ones with limited resources. Over time, the reduced costs contribute to superior financial performance of the business.
  • Flexibility: This crane type can be tailored to suit specific operational requirements, offering an unparalleled level of customization. It can be adjusted to cater for different weight capacities, height clearances, and even specific weather conditions, thereby significantly reducing the necessity for additional equipment.
  • Simplified Installation: Featuring a straightforward and swift installation process, these cranes can be ready for action in no time. This quick mobilization not only eliminates long installation delays that can stall projects but also reduces labor costs associated with installation, thereby generating savings.

The rubber tired gantry crane

An RTG crane, or a rubber tired gantry crane, is a mobile variant of the typical gantry crane. These cranes are frequently found in container terminals, ports, and integrated yards. Differing from ordinary gantry cranes that operate on rails, RTG cranes are fortified with rubber tires. This feature enables them to have unrestricted mobility across the ground, eliminating the necessity for tracks.

The component of rubber tired gantry crane

Main girder: The main horizontal beam that supports the hoist and trolley.

2. Rubber tires: Wheels that allow the crane to move and operate on the ground.

3. Hoist: The lifting mechanism that raises and lowers the load.

4. Trolley: The mechanism that moves the hoist horizontally along the main girder.

5. Controls: The system for operating and controlling the crane. The advantages of a rubber tired.

As for its advantages, it has a good mobility, versatility and it can need less space than other cranes.
