Double Girder Gantry Cranes from China Manufacturer

Double Girder Gantry Cranes introduction

Double girder gantry crane is a kind of lifting equipment suitable for high working frequency and heavy load environment. It is composed of portal steel structure, running mechanism, electrical system, etc. It is suitable for indoor and outdoor operation and is widely used for lifting materials, equipment installation and maintenance.

Main components
1.Main beam: supports the entire structure and ensures stability.
2.Support legs: connect the main beam and the end beam to carry heavy objects.
3.End beam: connects the main beam and the support legs to provide structural integrity.
4.Electric trolley: as a lifting mechanism, usually fixed on the top of the main beam.
5.Travel motor: drives the crane to move along the track.
6.Crane wheels: ensure the mobility of the crane.

Safety devices: overload limiter; high-quality, long-term, impact-resistant polyurethane buffer; crane travel limit switch; pressure loss protection, phase error protection; emergency stop system, brake system; lifting height limiter

Application
Double girder gantry crane is suitable for: high-intensity lifting operations, harsh working conditions, special operating requirements

Advantages：
1.Compact structure: reasonable design, space saving.
2.Flexible operation: suitable for a variety of working environments.
3.Strong load-bearing capacity: maximum lifting capacity can reach 320 tons, suitable for heavy lifting.
4.Large working range: wide adaptability to meet different operating needs.
5.Stable and reliable operation: high-quality design ensures safety and durability.

Comparative advantages with single-beam gantry cranes:
1.Higher power: double-beam design provides greater load-bearing capacity.
2.Complex design: more suitable for high-frequency and heavy-load environments.
3.Higher stability and safety: double-beam structure provides better support and reduces the risk of tilting.

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.
