ماذا تسمى الرافعة العلوية؟

يوليو 19، 2025

In modern industrial environments—from shipyards to warehouses—lifting and transporting heavy loads is a routine necessity. This is where overhead cranes come into play. But with so many variations and names, many ask: what is an overhead crane actually called, and what types exist?

The term “overhead crane” is often used as a general category for cranes that move loads horizontally over a workspace, supported by beams or tracks mounted overhead. However, depending on structure, mobility, and usage, different models have different designations—such as overhead gantry crane, رافعة نصف جسرية, or RTG crane.

Overhead Gantry Crane: The Classic Powerhouse

A gantry crane is a type of overhead crane where the entire structure, including the bridge and hoist, is supported by legs that move on fixed rails or wheels. When this gantry system is designed to span across a work area completely, it is commonly referred to as an overhead gantry crane.

This system is ideal for outdoor applications or areas without existing building support. In sectors like container handling or large component manufacturing, overhead gantry cranes provide full-span load control, making them a staple of large-scale operations.

YG Crane, a well-known manufacturer of advanced lifting solutions, offers a wide range of overhead gantry crane models with customizable spans, lifting heights, and tonnage. Their cranes are widely used in steel fabrication, precast yards, and logistics terminals.

Semi Gantry Crane: A Space-Efficient Alternative

There are times when a full gantry system will not be possible, for instance, in indoor sections of a building or where there is only partial support. In this case, the semi gantry crane would be used. The latter is such a version that one side is based on a rail supported by a building column or wall, while the other side has a traditional leg structure.

A semi gantry crane not only has a small footprint but also gets installed easily and quickly, and can efficiently handle goods in factories, assembly lines, and storage facilities. The companies can meet their lifting requirements easily with environmental and economic benefits, thanks to the unit’s dual-mode operation feature that requires no construction infrastructure changes.

Adaptability is the cornerstone of YG Crane’s semi gantry range. They have a range of models that are equipped with intelligent controls, variable speed drives, and safety devices, and can be transformed from simple maintenance work to a full-scale industrial task.

RTG Crane: The Container Champion

In shipping yards and intermodal terminals, speed and precision are paramount. The RTG crane, or rubber-tyred gantry crane, is designed to move large containers in stacked rows, often up to six or seven high.

Unlike fixed-rail systems, the RTG crane is mobile and operates on rubber tires, allowing it to move freely across container yards. It’s typically powered by diesel or electric engines and offers high stacking density, reduced downtime, and excellent maneuverability.

YG Crane has developed intelligent RTG crane systems with GPS-based positioning, anti-sway control, and automated container management. Their equipment helps improve container throughput while minimizing operator fatigue and error.

Why Naming Matters in Crane Selection

Understanding the differences between these crane types—overhead gantry crane, semi gantry crane, and رافعة RTG—is more than just terminology. It directly impacts your operational efficiency, facility layout, and long-term maintenance.

• Overhead gantry cranes are ideal for large outdoor areas or places lacking structural ceilings.
• Semi gantry cranes fit best in hybrid environments where space-saving and flexibility are key.
• RTG cranes are specialized for containerized cargo and high-volume yard logistics.

Each name points to a unique function, mobility type, and installation need. Choosing the wrong crane could lead to inefficiencies, underutilized space, or increased costs.
