This type of crane is based on the introduction and digestion of foreign advanced technology, guided by modular design theory, and modern computer technology as a means, introducing optimized design and reliability design methods, and is completed by using imported configurations, new materials, and new processes. A new type of crane with lightweight, generalization, energy saving, environmental protection, maintenance-free and high-tech content. The design, manufacture and inspection of this crane are in compliance with the latest national standards, and equivalently adopt some foreign standards such as FEM, DIN, and IEC. Compared with the original general QD type bridge crane products, its own weight is reduced by about 15-30%. The maximum wheel pressure is reduced by about 10~35%, which can reduce the requirements of the crane on the structure of the plant and save the manufacturing cost of the plant. The core components of the transmission mechanism, the reducer, all use hard tooth surfaces, high-precision gear pairs, plus the application of steel reels, forged wheels and variable frequency speed regulation systems, making this type of crane an updated product of the traditional general-purpose bridge crane. It is suitable for machinery manufacturing, assembly, petrochemical, warehousing and logistics, power construction, papermaking, railway and other industries.

Technical Parameter(customizable) of EOT Double Girder Overhead Crane:

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.
