Single-girder Semi-gantry Crane: an efficient "transporter" in industrial workshops
Classification:
Product Introduction
In the spacious industrial production workshop, a single-girder semi-gantry crane, a striking splash of industrial red, stands as a core piece of equipment. Its ingenious semi-gantry structure balances lifting flexibility with efficient space utilization—it can stably lift heavy materials while leaving ample space for production and traffic on the ground.

Technical Parameters:
| Lifting Capacity | 1 t - 32 t (different load tonnages can be customized according to needs) |
| Lifting Height | 6 m - 24 m (vertical effective lifting distance from the ground to the hook, adjustable as needed) |
| Span Range | 5 m - 35 m (adapt to the space width of different workshops, support non-standard customization) |
| Lifting Speed | 3 m/min - 12 m/min (adjustable according to the weight of the load, slow for heavy objects and fast for light objects, improving work efficiency) |
| Work Duty | A 3 - A 5 (light to medium work level, suitable for frequent operations such as daily lifting and material transfer in workshops) |
Core advantages:
- Efficient Space Utilization: The semi-gantry design allows for flexible operation in space-constrained environments like workshops. Its minimal height above the track surface eliminates the need for excessive overhead space, allowing for simultaneous production and traffic flow on the ground floor.
2. Excellent Lifting Performance: The single-beam structure, despite its light weight, can carry heavy loads (such as the heavy machinery components in the workshop shown in the image). It offers smooth lifting and low wheel pressure, achieving a balance between lightweight and powerful lifting capabilities.
3. Easy Operation and Installation: Operated with handles or remote control, it's easy to use. Modular connections between the bottom beam and brackets, and between the main beam and outriggers, enable quick installation and removal, and allow for flexible adaptation to workshop layout adjustments.
4. Safety and Customization: Safety features such as weight detection and travel limiter reduce operational risks. Customization is also possible based on the actual workshop dimensions, precisely matching production needs.
Several single-girder semi-gantry cranes are neatly arranged throughout the workshop. Under bright lighting, they precisely carry and smoothly transfer heavy loads, providing reliable lifting support for equipment assembly and material flow. From hoisting heavy machinery components to handling bulk raw materials, single-girder semi-gantry cranes, with their efficient performance, are a key enabler of the industrial production chain, making heavy lifting effortless and helping maintain a consistently efficient production rhythm.
Application Scenarios:
1. Manufacturing Workshops
Machinery Manufacturing: Lifting large machined parts, molds, and steel in machine tool and heavy machinery production workshops (as shown by the yellow construction vehicles and black heavy equipment in the workshop).
Automobile/Construction Machinery Manufacturing: Lifting large components such as engines, chassis, and frames alongside the production line, or assisting with the positioning of heavy objects during vehicle assembly.
Electronics/Home Appliance Manufacturing: Handling heavy metal sheets, injection molding molds, and other raw materials and equipment.
2. Warehousing and Logistics
Outdoor/Semi-Open Warehouses: Due to their semi-portal structure, they can be installed against the wall, making them suitable for lifting large cargo such as steel, lumber, and containers outside the warehouse or on the factory dock, with ground clearance.
Logistics Center Loading and Unloading Areas: Trucks and vans load and unload heavy equipment (such as generator sets and industrial pumps), reducing manual handling. 3. Metallurgy and Energy Industry
Metallurgical Workshops: Handling steel billets, rolling mill rolls, and non-ferrous metal profiles (requiring high-temperature resistance modifications), suitable for high-temperature, heavy-load environments in steel mills and aluminum processing plants;
Electric Power/Chemical Industry: Installing/maintaining transformers and boiler components in power plants; lifting heavy equipment such as reactors and storage tanks in chemical plants.
4. Construction and Infrastructure Scenario
In-Workshop Equipment Installation: Lifting precast concrete components and steel structure frames in construction engineering company workshops;
Temporary Construction Site Work: Lifting construction materials at the edge of the construction site (such as in factory expansion areas), balancing lifting and ground access.
5. Repair and After-Sales Service
Automotive/Ship Repair Shops: Lifting assembly components such as engines and transmissions; handling hull sections and propellers in shipyard workshops.
