Within the crane family, there is a particular group of members frequently seen in industrial settings: the overhead crane. Among them, the oldest and most established—truly the backbone of the family—is the electric single girder overhead crane.
The most common types of electric single girder cranes are the LD, LDC, and LDP models. But how can you tell them apart, especially since they seem like identical triplets? The key lies in their hoists—that’s where their main differences are revealed.
LD Electric Single Girder Crane (Standard Model)
The LD electric single girder crane is a light and small-sized overhead crane commonly paired with CD1 or MD1 electric hoists. It primarily consists of the main girder, end beam device, wire rope electric hoist, trolley running mechanism, and lifting electrical system. This crane is widely used in various environments such as factories, warehouses, and material yards.
Technical Parameters
Product Advantages
Compact Structure
The overall structure is relatively simple, with the main girder designed as welded I-beam to box-column connections, making both manufacturing and installation easy.
Light Weight & Low Wheel Pressure
With lower weight and reduced wheel pressure, this crane requires less load-bearing capacity from the building structure, saving on construction costs and making it suitable for facilities with lower load-bearing capabilities.
Cost-Effective
Compared to other types of cranes, the LD type crane offers excellent cost-performance, providing users with substantial savings in investment costs.
Flexible and Convenient Operation
The crane can be controlled either by a ground handle or wireless remote control, making operation simple and allowing for flexible movement within the workshop to precisely lift and transport materials.
Wide Application Range
Commonly used in factories, mechanical manufacturing, assembly lines, and warehouses—especially in environments where lifting frequency is low. It is versatile enough to handle a variety of material lifting, handling, and stacking operations.
LDC Electric Single Girder Crane (Low Headroom Model)
The LDC electric single girder crane is an improved version of the LD type crane. Its most notable feature is that the electric hoist operates directly on the lower flange of the main girder, often referred to as the “low headroom hoist.” This crane uses a box-type main girder design, with a “one open, two closed” gear transmission structure. The drive mechanism operates with separate drives for each component, and braking is achieved through a conical brake motor.
Technical Parameters
Note. Since the LDC type electric single-girder crane is an improved version of the LD type, their technical parameters are generally the same. However, the LDC model is specifically designed for use in buildings with limited ceiling height. It allows for maximum lifting height within constrained spaces, making it suitable for low-ceiling facilities. This crane model is typically customized based on customer requirements.
Product Advantages
High Space Utilization
Featuring a low headroom electric hoist and a uniquely designed main girder, the LDC crane enables a greater lifting height even in facilities with limited ceiling clearance. This maximizes the use of available space and helps reduce construction costs for buildings.
Smooth and Reliable Operation
The box-type main girder provides excellent stability, while the direct integration of the electric hoist with the lower flange of the girder ensures smoother crane movement. This design minimizes sway and vibration, enhancing operational safety and precision.
Easy Maintenance
With a simple and streamlined structure, the crane is easy to inspect, maintain, and service. The electric hoist eliminates the need for a complex trolley mechanism, reducing potential failure points and lowering both maintenance costs and downtime.
Wide Range of Applications
Suitable for various industries such as machinery manufacturing, assembly, warehousing, and logistics. It is particularly effective in environments where ceiling height is limited but a sufficient lifting height is still required, such as in factory renovations or low-rise workshops. Its adaptability makes it ideal for diverse material handling tasks.
LDP Electric Single Girder Crane (Side-Mounted Hoist Model)
The LDP type electric single girder crane is an ultra-low headroom, track-operated light-duty crane. Its distinctive feature is that the electric hoist is positioned on one side of the upper part of the main girder. This elevated trolley design maximizes the available lifting space below the hook, making it ideal for facilities where vertical clearance is limited.
Technical Parameters
Note. As an improved version of the LD type crane, the LDP type electric single girder crane shares similar technical specifications. However, it is specially designed for applications where the building structure imposes height restrictions. To meet the diverse requirements of different working environments, this crane model is typically customized according to customer needs.
Product Advantages
Efficient Space Utilization
As an ultra-low headroom, light-duty crane, the LDP model features the electric hoist mounted on one side of the upper part of the main girder. This design increases the hook service range and maximizes vertical space usage. However, installation requires sufficient clearance above the factory runway rails.
Wide Trolley Wheelbase for Smooth Operation
With a compact structure and excellent rigidity, the crane minimizes sway and vibration of the hoist during starting or stopping, ensuring smoother and more stable operation compared to traditional LD single girder cranes.
Excellent Handling Performance
Offers responsive, safe, and reliable operation with an attractive and functional design.
Low Energy Consumption
Features low noise levels, energy efficiency, and environmentally friendly performance.
How to Choose the Right Single Girder Overhead Crane
Select Based on Lifting Capacity
Determine the maximum weight to be lifted and the type of materials being handled to choose the most suitable crane model.
Match with Building Specifications
Measure the span, height, and other clearance dimensions of your facility to ensure compatibility with the crane’s design.
Choose the Control Method
Options include wired pendant control or wireless remote control, depending on operational needs.
Consider the Working Environment
For high-temperature, dusty, or humid environments, select cranes equipped with heat-resistant, dustproof, and moisture-proof components. For outdoor use, a rain cover is recommended.
