Top Running Cranes from China Manufacturer

Top Running Cranes Introduction

Top Running Cranes are designed for space-constrained working environments. Their compact structure makes them ideal for low-headroom facilities and can handle materials efficiently. The crane has a customizable configuration to adapt to different building layouts and operational needs. The reduced vertical profile enhances maneuverability, making it more flexible to operate in confined areas, thereby maximizing the utilization of ground space. In addition, the efficient design of Top Running Cranes is particularly suitable for transforming existing buildings and meeting the needs of rapidly changing industries such as manufacturing and warehousing. This type of bridge crane is known for its sturdy structure and excellent load capacity. It is mounted on tracks on the top of the runway beam, providing excellent stability and large spans. It can easily handle heavy loads and is very suitable for applications in heavy industries such as steel, automotive and shipbuilding.

Application: Top Running Crane is widely used in many occasions, including engineering workshops, machining workshops, mold assembly workshops, automobile manufacturing workshops, power stations, paper mills and metallurgical workshops. The use of wire rope hoists is particularly important in environments involving flammable, explosive or corrosive media, so users should clarify the specific use environment and conditions before choosing.

Space-saving design

The “space-saving design” feature of the top running crane is specifically designed for low-headroom building environments, aiming to optimize the lifting height for efficient work in confined spaces. Here are the key details of this design feature:

Compact installation: The electric hoist is installed on the side of the main beam, and the wheels run along the lower edge of the main beam, which greatly reduces the vertical footprint.
Small hook limit: Compared with traditional equipment, the hook limit size of the low-headroom hoist is smaller, which enables higher lifting capacity in confined vertical space.
Efficient space utilization: This design effectively responds to the challenge of limited vertical space, making material handling more flexible without affecting the load capacity of the crane.
Strong adaptability: The low-headroom design enables it to be easily integrated into various low-headroom buildings to meet the ever-changing industrial needs.
This design not only improves work efficiency, but also ensures the safety and convenience of users in various confined environments.

Design Scheme

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

The main beam and end beam are connected by high-strength bolts to ensure the accuracy and smooth operation of the whole machine.

A variable structure control scheme, a variable structure controller combined with a state feedback control scheme and an integrated control scheme are proposed to control the bridge crane.

We have a professional team of engineers to design and develop cranes, and have a complete technical system to analyze crane design drawings.

Our bridge crane component design and structure standards are certified according to DIN15018, BLATT2 and the steel structure welding standards are in accordance with DIN18800, BLATT7.

Equipped with a double-speed lifting mechanism, the running mechanisms of large and small vehicles all adopt frequency conversion stepless speed regulation.

All the plates are automatically cut by CNC cutting machine, and the camber of the main beam is preset to avoid the problem of deflection of the camber of the traditional fire-baked main beam.

The steel surface is treated with shot blasting and sand blasting to improve the adhesion of the paint and prevent the paint from peeling off, ensuring the long-term beauty of the whole machine.

Technology

The main welding seam adopts submerged arc automatic welding, non-destructive flaw detection, and the shape is beautiful to ensure the welding quality.

End beam material: high quality alloy steel Q345B.

The end beam is welded and formed by rectangular steel pipe or steel plate, and the formed end beam is positioned and processed on a CNC boring and milling machine at one time to ensure dimensional accuracy and fit tolerance.

The lifting trolley has a modular design, and the working level is FEM M4-M6. The entire lifting trolley has a compact structure, low headroom and light weight.

Production

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

The main girder of the crane is welded by steel plates, and the steel plate materials meet the international crane production standards. The main steel structure materials we use are not lower than Q235B, and the materials used have material reports and corresponding qualification certificates.

There are buffer blocks at both ends of the end beam to reduce the impact force of the collision and reduce the impact inertia. The beam body of the whole machine adopts shot blasting and painting process according to the world standard.

The running track of the trolley is made of square steel to increase the effective contact area of the wheel tread and reduce the weight of the track. The material of the square steel track is Q345B.

The operation room is operated by a linkage table, and is equipped with a remote control at the same time. Through the switch, it can be operated by remote control or switched between operations during operation. Lighting and seats are installed indoors, and the entrance of the operating room is end-entry, which conforms to European and international standards.

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.

MAINTENANCE AND SECURITY

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

The cranes we produce are equipped with a safety monitoring system, which is professionally developed by the company in accordance with FEM/DIN/ISO/GB related standards, and is used for crane operation data recording, safety protection, and electronic instruments for status display.

The safety monitoring system has real-time protection functions for more than 30 working conditions such as operating failures, safety hazards and illegal operations, preventing the crane from operating in potentially dangerous situations and ensuring the safety of personnel and equipment.

Schneider TE is a vector frequency conversion control system specially developed for European crane components.

There is shock-absorbing plastic raw material derived wedges at both ends of the crane landing gear.

Overload protection, residual current relay, PTC thermistor, crash sensor, emergency stop button, sound/light warning and warning siren are standard protection units for all our overhead cranes.

At the time of delivery, we will provide customers with crane safety operation manuals and maintenance manuals. If the customer needs it, we will also send safety engineers to the site to know the customer's safe installation.
