Description
The Weihua L-type electric hoist gantry crane is an economical lifting device launched by Weihua Group for the light and medium-sized material handling market. It is used in conjunction with wire rope electric hoists of models such as CD1 and MD1, and is a small to medium-sized rail-mounted gantry crane. Named for its inverted "L"-shaped outriggers, this product is a classic model in the L-type single-girder gantry crane family, perfectly combining the lightweight advantages of a single-girder structure with the ingenious design of the L-shaped outriggers in terms of overall height.
This product is a general-purpose crane with a lifting capacity ranging from 5 to 10 tons (main hook), a suitable span of 12 to 30 meters, a maximum lifting height of 12 meters, and a working class of A5. It is suitable for working environments from -20℃ to +40℃. The product can be widely used for loading, unloading, or grabbing materials in open-air freight yards, warehouses, and along railway lines.
In terms of structural design, the L-type electric hoist gantry crane adopts a single main beam off-center box girder structure. The gantry mainly consists of a main beam, two legs (one rigid and one flexible design is used when the span is ≥30m), a trolley running track, and a lower crossbeam connected by high-strength bolts. The L-shaped leg design makes the overall height of the machine lower for the same lifting height requirement, effectively saving costs and making it particularly suitable for working environments with height restrictions.
In terms of control methods, the L-type electric hoist gantry crane offers three modes: ground operation, remote control, and cab operation, allowing users to flexibly choose according to their working environment and operating habits. With its compact structure, light weight, low cost, simple operation, and safe and reliable operation, it is an ideal choice for small and medium-sized enterprises and open-air freight yards to achieve mechanized material handling.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
L-shaped outrigger design – Low overall height, cost savings
The core competitiveness of the L-type electric hoist gantry crane stems from its unique L-shaped outrigger design (an inverted "L" shape). Compared to A-type (A-frame) outriggers, the L-shaped design achieves the same lifting height with a lower overall height, effectively saving manufacturing costs and installation space. This feature is specifically reflected in:
Low overall height: For a given lifting height, the L-shaped structure saves more space than A-type outriggers, making it particularly suitable for operating environments with height restrictions, such as those with aviation height restrictions or where adjacent factory buildings have height limitations.
Good structural stability: The outriggers are connected to the main beam and lower crossbeam via high-strength bolts, forming a stable gantry system. The reasonable trolley base distance ensures stable and reliable operation of the entire machine.
Rigid-flexible outrigger design: When the span reaches 30 meters or more, a rigid-flexible outrigger design is adopted, effectively adapting to temperature changes and manufacturing and installation errors, ensuring long-term stable operation of the equipment.
Compact and Lightweight Design – Low Weight, Low Wheel Pressure
The L-type electric hoist gantry crane incorporates lightweight and compact design principles in its structural design:
Single Main Girder Structure Advantages: Utilizing a single off-center box girder as the main girder simplifies the overall structure and significantly reduces weight compared to double main girder gantry cranes. This design advantage is particularly pronounced in the 5-10 ton lifting capacity range.
Low Wheel Pressure, Lower Civil Engineering Costs: The lighter weight directly reduces wheel pressure, lowering the requirements for the ground track foundation and effectively saving on civil engineering investment.
Convenient Manufacturing and Installation: The gantry steel structure uses high-strength bolt connections, allowing for modular transportation and on-site assembly, resulting in a short installation cycle and low labor costs.
