5 - 80 Ton Double Beam Overhead Travelling Cranes With Hoist Trolley FEM / DIN Standard

FEM/DIN Double Girder Overhead Crane With Hoist Trolley

General description:


Design and fabricate according to FEM/DIN standard, Double Girder Bridge Cranes are most frequently used where capacities over 10 tons and/or spans of 60 to 100 ft are needed. They can be utilized at any capacity where extremely high hook lift is required because the hook can be pulled up between the girders. Double Girder Bridge Cranes are also ideal where high speeds and heavy service are required. They are highly suitable where the crane needs to be fitted with walkways, crane lights, cabs, magnet cable reels or other special equipment.


Main feature:

- Double welding box girder, DIN/FEM standard deflection, it has smaller body to get more lifting space.
- Material Fe37 or Fe52
- Whole length CNC cutting for complete web plate, high deflection accuracy
- High quality autometic welding and NDT inspection
- Shot-blasting Sa2.5 for complete girder after welding, stress release
- Each end carriage is supplied with wheels with double-wheel rim, buffer and anti-derailing protection device.
- The lifting unit is wire rope electric hoist, it is low headroom frame electric hoist, it takes smaller space on vertical direction.
- All motions of this overhead crane are double speeds, the lifting motor is double speed type, the cross travelling motor and long travelling motor are controled by frequency inverter.


Advantages:

  • Light duty & modular design

1. The overall height of the crane can be lower 20%~25% of the tradition crane.
2. The dead load reduced by 20%~30%.
3. The maximum wheel pressure can deduct by 15% ~ 20%
4. The small limit dimension can increase the working area.
5. With the lightness structure it can cut the construction costs.
6. Each spare parts on the crane can be design to series standard modulus , it can lavish the product combination
7. Its independent modulus is convenient for the transportation.
8. Standard modulus production, it can ensure stability quality of the product, it can shorten the delivery period.

  • Advanced Fabricated Technology

1. Sandblasting pretreatment for the steel plate, its surface quality can reach to Sa2.5.
2. Using digital cutting machine to cut the web plate, ensure the smooth and precision of the camber curvilinear.
3. Main welding seam adopts auto arc merged welding, Ultrasonic, X ray nondestructive inspection.
4. The bridge and trolley frame adopts floor type boring machine to ensure the flatness of the machine side.

  • High Security

1. The safety supervises system equipped with overload limiter, and on the monitor it can display the loads value, it can remind the operator to prevent the overload.
2. Before the start, the entire controller will start self checking, includes: power voltage, default phase, the effective of each safety protective device and zero position of the button.

  • High Reliability

1. Imported motor, the insulation grade is F, and protective grade is IP54, it shall also have over heated and alarming function, the motor cover adopts aluminum alloy to drawing the molding, with better heat dissipation.
2. Germany imported reducer, harden face gear, improve the bearing ability, better sealing of the shell, ensure there no grease penetration.
3. The main electric elements adopts the international brands include Schneider, Siemens, ABB. The protective grade of the electric control box shall no less than IP 54.
4. The wheel forged by 65 Mn alloy steel, with the performance of abrasive resistance, ant fatigue and long service life.

  • Low-energy and Maintenance-free

1. The total power of crane reduce about 30%, energy conservation and environmental protection.
2. The multi -in-one integrated transmission mechanism has less intermediate ring knot and high transmission efficiency.
3. Adopt frequency control, high and low speed ratio 1:10, work efficiency increased by more than 20%.
4. The "Maintenance-free and easy maintenance "design concept reduces customer maintenance costs.
5. It uses advanced processing technology and high -quality imported components. Its failure rate has been greatly reduced compared to traditional GB crane, helping customers reduce operating costs.

  • Intelligentialize

1. World's leading electrical anti- sway technology can be installed on the crane to achieve precise positioning.
2. Advanced electrical control technology can achieve the semi-automatic and automatic control lifting, so that the crane becomes "Lifting robot ."
