SKETCH

Main technical

 

The MH-type electric hoist gantry crane is widely used in industries due to its flexibility, cost-effectiveness, and ease of installation. Here are its key advantages:

1. No Need for Overhead Runway

Unlike bridge cranes, which require a fixed runway beam, gantry cranes are freestanding, making them ideal for workshops without permanent support structures.

2. Easy Installation & Portability

Can be quickly assembled without complex foundations.

Some models are adjustable in height & span, allowing relocation as needed.

Mobile gantry cranes (with wheels) can be moved manually or electrically.

3. Cost-Effective Solution

Lower initial cost compared to overhead cranes (no need for building modifications).

Minimal maintenance (simple mechanical structure).

4. Versatile Load Handling

Supports electric chain hoists (0.5–10 tons) or wire rope hoists (up to 20+ tons).

Can be customized with rotating trolleys, grabs, or magnets for special loads.

5. Suitable for Indoor & Outdoor Use

Rubber-tired models work on flat floors.

Rail-mounted models provide precise movement in harsh environments (e.g., shipyards).

6. Safe & Reliable Operation

Equipped with overload protection, limit switches, and emergency brakes.

Stable structure (wider legs prevent tipping).

 

This crane is used in various industries for lifting, moving, and positioning loads efficiently. Common applications include:

1. Warehousing & Logistics

Loading/unloading pallets, containers, and heavy packages.

Stacking goods in storage yards.

2. Manufacturing & Workshops

Handling machinery parts, molds, and assembly lines.

Moving steel beams, pipes, and raw materials.

3. Construction & Infrastructure

Lifting precast concrete panels, rebars, and construction materials.

Assisting in bridge and road construction.

4. Shipbuilding & Ports

Moving ship components, engines, and containers.

Used in dry docks and repair yards.

5. Railway & Automotive

Lifting locomotives, rail tracks, and vehicle parts.

Used in repair garages and maintenance shops.

6. Power Plants & Heavy Industries

Handling turbines, generators, and heavy equipment.

Used in steel mills and foundries.
