Semi Gantry Cranes from China Manufacturer - Henan Seven Industry Co., Ltd

Semi Gantry Cranes

Semi gantry cranes are a type of lifting equipment between bridge cranes and gantry cranes, usually supported by a single or multiple beams, utilizing a ground mounted track and a raised track. This design allows full utilization of available space in the working environment and is widely used in material handling in machine shops.

Main components: lifting mechanism and trolley: main beam; outriggers; end beams; electric control box; operating system; safety protection system, etc.

Advantages：
1. Space saving: Compared with bridge cranes, it reduces the plant space occupied by columns; compared with gantry cranes, it saves production space.
2. Cost-effective: By using the plant structure to replace the new legs of the crane itself, higher cost-effectiveness is achieved.
3. Flexibility: Since it is not completely dependent on the plant, semi-gantry cranes are superior to traditional EOT cranes in flexibility.
4. Safety: It can be installed under the existing bridge crane and equipped with necessary safety devices.
5. Wide range of applications: semi gantry cranes are suitable for indoor and open-air use, providing a variety of solutions, including double-beam and single-beam semi-gantry cranes.

Applications：
Semi-gantry cranes are widely used in the following areas: steel industry; forest product handling; intermodal; biomass/pellet handling; concrete production; warehouses, construction sites, docks, power stations, etc.

（In certain situations, semi-gantry cranes can be equipped with truss-type outriggers to enhance their structural stability.）

There are two typical applications:

Indoors, usually used under existing overhead cranes to provide more hooks, thereby improving the productivity of the factory.
Outdoors, often used near buildings, making full use of existing runway structures, thereby improving the cost efficiency of factories or plants.

Based on the carrying capacity, this special type of gantry crane can be divided into single-beam semi-gantry cranes and double-beam semi-gantry cranes.

Design Scheme

SEVENCRANE stands for first-rate service, cost-effective, high quality.

Bolt structure connection and plug-in electrical connection are adopted, which makes installation and maintenance more convenient, flexible structure and more stable operation.

The maximum deflection of the European-style gantry crane produced by our company is less than 3mm.

Bolt structure connection and plug-in electrical connection are adopted, which makes installation and maintenance more convenient, flexible structure and more stable operation.

Our crane steel welding standards follow DIN18800, BLATT7 specifications.

The crane structure and production design scheme comply with the third edition of FEM1001 standard.

The double speed of the overhead crane is precisely provided by the double speed motor and frequency converter. We select the motors according to the FEM standard, the motor models are IEC Recommendations34-1, 34-5 and 72-1.

The motor gearbox is designed according to ISO/DIS6336/Ⅱ-6336/Ⅴ[DIN51150] standard.

Technology

The lifting trolley adopts European-style optimized modular design, with more compact structure, low clearance height, light weight and strong lifting capacity.

The wheels are driven by a multi-key system which minimizes wear on the wheels and drive shafts.

SEVENCRANE gantry cranes are designed and manufactured with much the same technology as overhead crane systems.

The whole machine adopts the most advanced optimization technology, and the European design can save your construction cost and provide the most effective solution for your project.

Production

SEVENCRANE stands for first-rate service, cost-effective, high quality.

It has a professional crane technology research and development team and a complete production line and equipment assembly line, and the process is perfect.

The lifting equipment produced by SEVENCRANE has passed the product certification of many regions, countries and organizations, and our products have also been exported to more than 30 countries and regions.

Our crane design concept is an extension of the European concept, and we have summarized our unique production technology and solutions through long-term in-depth research and application practice.

The whole process of production is basically automated, and the outsourcing of all crane bridge beams is welded by submerged arc welding robots to improve welding accuracy.

The whole process of crane equipment production is monitored by technicians and engineers, so the quality of product production is guaranteed.

MAINTENANCE AND SECURITY

All operators in our production workshop must hold legal operating certificates.

Gantry cranes are maintained and overhauled in accordance with the prescribed European standards.

Operators have been professionally trained and understand the structure, performance, operation methods and safety matters of European cranes before taking up their posts with certificates.

All our production indicators and technologies are aimed at ensuring the safe and stable operation of European-style cranes, preventing accidents caused by human factors, and ensuring the safety of personnel and property.

Safety protection devices such as limit switches, overload limiters, PTC thermistors, collision sensors, and emergency stop buttons ensure the stability and safety of the crane during operation.

All gantry cranes are equipped with a standard-compliant service platform for safe maintenance and inspection by service personnel.

The gantry crane operating manual, electrical diagrams and related instructions for electrical and electronic components will be delivered to the customer when the crane is shipped.
