Single Girder Overhead Cranes from China Manufacturer

Single Girder Overhead Cranes introduction

Single girder overhead crane is a lifting device that is horizontally placed over the indoor and outdoor working spaces such as workshops, warehouses and stockyards for material lifting. The bridge frame of the single girder bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. Because it provides cost-effective solutions for many projects, it is currently the most widely used and largest number of hoisting machinery.

Single girder EOT cranes have a wide range of applications, and are widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industry, railway transportation, port terminals, and logistics turnover and other departments and places. And the lifting capacity of the single-girder EOT crane produced by our company has no upper limit, and can be customized according to customer requirements.

In addition, the single girder bridge crane is lighter than the double girder bridge crane, and the maintenance operation is more convenient. Moreover, the single girder bridge crane is sometimes installed under the double girder bridge crane to facilitate the maintenance of the double girder bridge crane. We also equip the motor and engine of the electric single girder crane with protective cover and rainproof device to increase its service life. And its bridges generally adopt box structure, and can also be made of standard profiles or structural steel according to customer requirements.

Design Scheme

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

04

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

05

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.

06

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.
