L Electric Trolley Gantry Crane - Henan Seven Industry Co., Ltd

L Electric Trolley Gantry Crane Introduction

L Electric Trolley Gantry Crane is a medium-light lifting equipment equipped with an electric hook and an “L”-shaped outrigger design, which is convenient for handling long cargo (such as steel pipes). Its lifting capacity ranges from 5 to 32 tons and is suitable for use in working classes A5 and A6.

Components:
The electric trolley gantry crane is mainly composed of a bridge, L-shaped legs, a mobile trolley system, an electric trolley and an electrical system.

Features and Advantages:
1. Structural composition: It is mainly composed of four parts: bridge structure, walking mechanism, trolley and electrical equipment.
2. Bridge design: It adopts box beam welding structure, and the running mechanism of the end beam is driven separately.
3. Centralized control: All operations are carried out in the cab to improve the convenience of operation.
4. Customization: Parameters such as ambient temperature, power short circuit and voltage can be adjusted according to customer requirements.
5. Novel design: novel structure, exquisite appearance and advanced technology.
6. High efficiency and safety: high working efficiency and strong safety.
7. High cost performance: It provides high-quality performance and has good cost performance.
8. Wide adaptability: It has strong adaptability and is suitable for a variety of working environments.
9. Space saving: The L-shaped outrigger design saves cargo space and is convenient for carrying long cargo.
10. Flexibility: The outrigger can be easily transferred to other sites to enhance the flexibility of operation.

Safety protection:

1. Rain cover: protect the crane, drive unit and electrical cabinet from rain.
2. Warning system: equipped with flashing lights and warning sound effects to improve safety warning effects.
3. Wireless infrared detector: prevent unauthorized access.
4. Multiple protection devices:
Overload protection
Overcurrent protection
Overvoltage protection
Rail clamp
Weight overload protection
High-quality and durable polyurethane buffer
Trolley travel limit switch
Low voltage protection
Emergency stop system
Current overload protection system

The above measures ensure safe operation and reduce the risk of accidents.

Application areas:
1. Cement plant: used for material handling and equipment installation.
2. Construction industry: supports the handling of building materials and construction operations.
3. Electronics industry: handles electronic products and components.
4. Warehouse: assists in warehouse management and cargo loading and unloading.
5. Railway: suitable for the handling of rail transit related equipment.
6. Food industry: used for the handling and processing of food materials.
7. Papermaking industry: supports the transportation of paper and paper products.
8. Engineering industry: widely used in material handling of various engineering projects.
Note: It is forbidden to use in high temperature, flammable, explosive and corrosive environments, and overloading is strictly prohibited.

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.
