Qual é a ponte rolante mais comum? Um guia da YG Crane

Mai 29, 2025

Overhead cranes are very important utilities in material handling of various industries—starting from manufacturing plants and warehouses to shipyards and construction sites. When first-time buyers or facility managers are confronted with the choice of cranes, they often ask the question: What is the most common overhead crane?

YG Crane is a company that has had numerous industrial clients to whom they have been glad to provide crane systems that are tailor-made so they can get the most out of their safety, efficiency, and cost-effectiveness. According to our observation, the one girder crane is the one that really pops up as the most commonly seen overhead crane type, particularly in fields that do not impose the heaviest of workloads.

Through this article, we will highlight the reasons behind the single girder technology’s preference, its overview, other varying types, similar to the eot crane and semi-gantry crane, and how one should factor in their operational environment when selecting a crane.

Industrial Overhead Crane

What Is a Single Girder Crane?

A grua monoviga consists of a single beam—usually supported by end trucks—that spans the width of the workspace. A hoist trolley travels along the lower flange of the beam, enabling horizontal movement, while the hoist itself provides vertical lifting.

Why It’s So Common:

  • Cost-effective structure with fewer materials
  • Simpler installation and maintenance
  • Ideal for loads up to 20 tons
  • Fits well in facilities with low headroom
  • Compatible with both top-running and under-running designs

This makes it the go-to choice for small-to-medium-sized workshops, warehouses, and maintenance facilities.

What About EOT Cranes?

Um EOT crane (Electric Overhead Traveling crane) is a broad category that includes both single and double girder overhead cranes. It’s electrically powered and operates on a fixed runway system attached to building columns or an independent structure.

Em YG Crane, we classify gruas eot into:

  • Single girder EOT cranes (most common for light to medium duty)
  • Double girder EOT cranes (for heavier loads and wider spans)

While technically, a grua monoviga can be an grua eot, the term “EOT” emphasizes its electrical and automated operation features.

Semi Gantry Crane: A Space-Saving Hybrid

O guindaste semi-pórtico is a variation of the overhead crane, typically used in environments where a full runway system isn’t possible. It has one end riding on an elevated runway (like an overhead crane) and the other end running on the floor (like a gantry crane).

Ideal for:

  • Outdoor or mixed indoor/outdoor facilities
  • Workshops with limited support structure
  • Applications requiring flexible mobility and clear floor space

Although not as commonly used as single girder cranes, semi gantry cranes are essential in specialized settings like shipyards or steel yards.

Key Advantages of Choosing a Single Girder Crane

  1. Lower Cost
    Fewer components mean lower production and maintenance costs—ideal for budget-conscious facilities.
  2. Faster Installation
    Lighter and more compact, single-girder systems are quicker to install, minimizing operational downtime.
  3. Energy Efficient
    Because the crane is lighter, motors consume less power, resulting in long-term energy savings.
  4. Reliable for Daily Operations
    For standard material handling tasks—lifting tools, components, or containers—the single girder design is more than sufficient.
