1. The L-type single-girder gantry crane is suitable for general loading/unloading, hoisting, and lifting operations in open-air freight yards and along railway lines.
2. Due to its structural characteristics, the L-type gantry crane reduces the overall height of the machine while maintaining a certain lifting height, saving costs.
3. It features light deadweight, low wheel load, and reliable performance.

Structural & Design Features

Manufacturing Process: The main girder uses CNC cutting for blanking and advanced welding processes such as submerged arc welding.
Core Structure: Features an L-type structural design, where two columns are connected to the rear of two bases with rollers, forming a stable “L” shaped support. The main girder (gantry) is mounted on these two columns, and the bridge mainly adopts a box-type welded structure, providing good strength and rigidity.
Travel Mechanism: The crane travel mechanism typically uses separate drives, meaning the drive wheels under each leg operate independently, offering flexible steering.

Advantages & Features

Stable Structure

The L-type structure is stable, with light deadweight, low wheel load, and reliable performance, contributing to operational safety.

Flexible & Efficient

Multiple control modes (ground, remote control, cabin) adapt to different needs. Combined with flexible drive forms, it effectively enhances loading/unloading efficiency.

MH series truss-type gantry crane with electric hoist

cn_whcrane — Mon, 08 Dec 2025 02:32:33 +0000

The MH型 electric hoist gantry crane (truss type) is used in conjunction with electric hoists such as the CD₁ and MD₁ models. It is a medium and small-sized rail-mounted crane with a applicable lifting capacity of 3-16 tons and a applicable span of 12-30 meters. The working environment temperature ranges from -20°C to +40°C.
The MH型 hoist truss gantry crane is a general-purpose crane, mostly used for loading/unloading or grabbing materials in open-air sites and warehouses. This product comes in two types: ground control and cabin control.

Structural Composition

The metal structure of the MH型 electric hoist gantry crane (truss type) mainly includes:

Crane Travel Mechanism: Drives the entire crane to move longitudinally along the ground rails.
Main Girder: Adopts a truss structure welded from section steel. This structure effectively reduces the overall weight and helps to decrease wind resistance, enhancing stability when working in open-air environments.
Legs and Lower Crossbeam: Also made of steel structure, connected to the main girder to form the gantry. The main girder, legs, and lower crossbeam are usually connected using high-strength bolts, facilitating transportation and on-site installation.
Hoist Trolley: This refers to the matching electric hoist, which runs directly on the I-beam of the main girder’s lower flange and is responsible for lifting and transverse movement.

Electric Hoist Type Selection

The types of electric hoists installed on the MH型 electric hoist gantry crane are typically selected based on usage scenarios and requirements as follows:

CD₁/MD₁ Wire Rope Electric Hoist

Explosion-Proof Electric Hoist

MH electric hoist gantry crane

cn_whcrane — Wed, 03 Dec 2025 09:05:12 +0000

The MH electric hoist gantry crane is a common light and small lifting device. It is particularly suitable for cargo handling operations in warehouses, factories, and docks. It mainly consists of the bridge (including the main girder and end carriages), hoisting mechanism, travel mechanism, and electrical control system. This single-girder gantry crane is popular due to its compact structure, simple operation, and small footprint.

The electric hoist gantry crane adopts a single-girder design, meaning there is only one main girder spanning the two end carriages. Its main girder is the primary load-bearing component for heavy loads, and its material selection and manufacturing process directly affect the safety and service life of the entire equipment. As the core component of the hoisting mechanism, the electric hoist is located under the main girder and moves along it to achieve vertical and horizontal material handling.

Electric Hoist Type Selection

The types of electric hoists installed on the MH type electric hoist gantry crane typically have the following options based on usage scenarios and requirements:

CD1/MD1 Wire Rope Electric Hoist

Explosion-Proof Electric Hoist

Electric Chain Hoist

New Chinese Style Electric Hoist

CD1 Electric Hoist: Single-speed lifting, simple structure, more widely used.
MD Type Wire Rope Electric Hoist: Dual-speed lifting, including normal and slow speeds, suitable for work environments requiring precise positioning.
Explosion-Proof Electric Hoist: Suitable for flammable and explosive environments, such as the chemical industry, coal mines, and other industries.
Electric Chain Hoist: Suitable for small tonnage, light-duty working conditions, compact structure, and easy maintenance.
New Chinese Style Electric Hoist: High performance, low deadweight, frequency conversion design, smooth operation, commonly used in modern factories with higher requirements for efficiency and maintenance.

Advantages & Features

Simple Structure

Adopts box-type or I-beam structure with a reasonable design, light weight, and easy installation and maintenance.

Flexible Operation

Supports floor operation and smooth running, suitable for different locations such as factories, warehouses, and sites.

High Cost Performance

Manufacturing cost is relatively low, suitable for small and medium tonnage lifting needs, making it an economical and practical choice.

Strong Applicability

Can be matched with CD, MD, European, and other electric hoists to meet the requirements of different working conditions.
