The MH type single-girder gantry crane with electric hoist is a small to medium-sized lifting equipment under Weihua Group, suitable for outdoor or indoor fixed bays. It is typically used in conjunction with CD1 or MD1 type electric hoists. Characterized by a simple structure, economy and practicality, and easy installation and maintenance, it can meet the general lifting needs of various scenarios such as factories and freight yards.
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 HoistExplosion-Proof Electric HoistElectric Chain HoistNew 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.
