European Style Single Hook Double-Beam Bridge Crane Workshop Operation

Product Description of EOT Double Girder Overhead Crane

European-style double-beam bridge crane performance advantages: superior performance, compact structure, light weight, safe and reliable, and efficient in operation, which can meet various working conditions. It can reduce the overall investment of the plant, improve production efficiency, reduce maintenance costs, save operating energy consumption, and obtain a better return on investment. Scope of application: It is used for loading and unloading and moving heavy objects in machinery manufacturing workshops, electronics, precision machinery, automobile manufacturing, new energy, biopharmaceuticals and other places.

The European-style double-beam bridge crane is used in conjunction with the European-style electric hoist and runs on the track to become a higher crane capable of lifting. Generally, the lifting weight is 0.5t~50t, the span is 7.5~31.5m, and the running speed is 4-20m/min and 5-30m/min. If there are special requirements, it can be designed and manufactured separately.

The double-beam bridge crane is the most convenient and maintenance operation mode in industrial use in our country, and the production line of the enterprise also has maintenance measures such as maintenance of this equipment. Among the cranes that are prone to damage, our country has this wear-resistant material, and the energy consumption is relatively small, and the service life is relatively long, which can bring the most effective economic benefits and development to customers.

Advantage
1. It has light weight, compact structure and low energy consumption. A trolley and a lifting mechanism are set on the bridge frame. The trolley can run back and forth, and the trolley runs to realize the transportation of materials and objects in the three-dimensional space.
2. European-style crane adopts a unique design concept, which has the characteristics of small size, light weight and small wheel pressure.
3. Compared with traditional cranes, the limit distance from the hook to the wall is the smallest and the headroom is the lowest. The crane can work closer to the front and has a higher lifting height, which actually increases the effective working space of the existing plant.
4. Because the crane has the characteristics of light weight and low wheel pressure, the new workshop space can be designed to be smaller and more complete.

Selection instructions

1. This product series table only lists the commonly used basic specification cranes, the standard span when the working class is A5 (FEM2m), and indoor cranes without auxiliary hooks. Customers can put forward corresponding requirements according to their needs.
2. This series can also increase the auxiliary crane mechanism, and can also increase the setting of doubling the speed at light load. Generally, the main and auxiliary setting is 4:1, and it can also be set according to customer requirements. The installation of auxiliary hooks will increase the total weight and wheel pressure of the crane.
3. The size, weight, and wheel pressure in the table are for customers' reference when ordering. If the customer’s requirements change, such as the working level, speed, and lifting height, the corresponding parameters, dimensions, weight, wheel pressure, etc. will be changed. If changes occur, the actual parameters, quality, and wheel pressure are subject to the requirements of the contract.
4. The lifting speeds listed in the table, the speeds of large and small cars are standard values, and can be adjusted accordingly according to customer needs.
5. Technical parameters and dimensions will change due to technical improvements or upgrades. If you have any questions, you can contact the company's technical department.

Main Features of EOT Double Girder Overhead Crane:
1. Light weight: The design software developed by the company, combined with three-dimensional modeling and finite element analysis, adopts the most reasonable structure from the lifting mechanism, steel structure to accessories, and the large-scale application of high-strength materials improves the load-bearing capacity. It can reduce its own weight, which is lighter than traditional cranes and has lower wheel pressure.
2. Small footprint: the limit distance from the hook to both sides is small, the working range is large, the height above the track surface is small, and the workshop space is effectively used.
3. Low operation and maintenance cost: due to the small wheel pressure and small size, it can reduce the investment in the early stage of the factory building, while the lighting, heating and other facilities can also save a part of the cost, and the product performance is reliable and durable, so that the later product is in use. The cost of accessories required in the system is reduced to a minimum. The optional high-quality, high-performance parts greatly reduce the workload of maintenance and repair, the total installed power is reduced, and the use cost can be saved.
4. High working performance: using frequency conversion technology, heavy load slow speed, light load fast, speed adjustment range 1:10, the crane runs smoothly, reducing the impact on the plant. Combined with anti-sway technology, high-precision positioning of lifting objects can be realized.
5. Convenient operation
6. Green manufacturing technology: adopting green design concept, wide-range application of high-strength materials, seamless blanking of main beams, automatic welding technology and laser cutting technology, realize energy saving and environmental protection in the production process, and reduce environmental pollution.
7. Fast positioning

Trolley (winch type)
Trolley operating mechanism: three-in-one compact structure of motor, reducer and brake, motor insulation class F, protection class IP55, load continuity rate 40%, with thermal protection, power distribution disk brake, reducer hard tooth surface, and After grinding or shaving, the gearbox does not need to change oil during its service life.
Forged wheels, rim and tread hardness HB330 ~ 380.
Frequency conversion speed regulation, heavy load slow speed, light load fast, speed range 1:10, smooth operation without impact.
The trolley limit switch adopts a cross travel limit switch, which reduces the running speed of the trolley to zero before the trolley buffer collides with the end stop of the trolley track.
The lifting mechanism adopts a three-point installation form. Both ends of the reel are directly supported on the end beams on both sides of the trolley frame. The pulley beams are connected by bolts to connect the end beams on both sides to form a longitudinal beam. The output shaft of the reducer is sleeved and connected to the extended winding shaft, and the lifting motor and the reducer adopt an elastic body coupling.
1. Welding reel: The reel is made of short-shaft steel plate, with bearing seats at both ends, and a sleeve shaft extending from one side. The structure is simple, and the adjustment and installation are convenient.
2. High-strength galvanized steel wire rope: the nominal tensile strength is 1870kN/mm2, the steel wire rope does not need to be coated with anti-rust oil, and it is maintenance-free
3. Hoisting motor: the standard configuration is a frequency conversion motor, optimized air-cooled, insulation class F, protection class IP55, and the power-on duration rate is 40%.
4. Lifting reducer: tooth surface carburizing and hardening treatment, hardness HRC60, and after grinding or shaving, light weight, good sealing and no oil leakage.
5. Lifting brake: Normally closed brake with automatic wear compensation, which can be manually opened and released in an emergency state through a separate manual operation. If necessary, double brakes can be set.
6. Hook group: The hook group is composed of hooks and pulleys. The hook material is DG34CrMo. The pulley material is Q235 hot-rolled, using anti-friction roller bearings, the hook can rotate 360°, and the safety buckle with spring compression can prevent slippage. All pulleys use maintenance-free bearings. The pulley design can effectively prevent the wire rope and the pulley shell from abrasion. The overall structure is exquisite in volume and beautiful in appearance.
7. Lifting limit: cam rotary type, 4-level adjustable, upper and lower limit, automatic reset, safe and reliable. The rising pre-limit reduces the impact, and the limit limit prevents the hook from rushing to the top.
8. Car electric control box: protection grade|P55, aviation plug, quick installation.
