Introduction

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 Electric Hoist: Single-speed lifting, simple structure, widely used.
MD型 Wire Rope Electric Hoist: Dual-speed lifting, including normal and low 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

Lightweight, Cost-Effective

While ensuring strength, the truss structure is lighter than box girder structures, which can reduce requirements for rail foundations and manufacturing costs.

Strong Environmental Adaptability

Designed for temperature differences ranging from -20°C to +40°C, meeting the needs of outdoor operations in most parts of China.

Reliable Basic Functions

As a mature medium and small-sized crane, its design and manufacturing follow relevant industry standards, ensuring basic operational stability and safety.

Convenient Operation

Provides two common control modes: ground pendant control and cabin control, which can be flexibly chosen based on operational frequency and requirements.
