Interpret the hardcore technology of EED's EDM lifting drive

Imagine this scene: At a busy port terminal, huge containers are easily lifted and precisely placed on cargo ships. In the bustling steel factory, hundreds of tons of molten steel ladles were smoothly transported, and the entire process was smooth and fluid. Behind all these "grand scenes", there is always a core piece of equipment - the bridge crane.

The key to whether a crane can lift a "thousand-pound weight" steadily lies in its lifting drive device and motor. If they are not powerful enough, not only will the efficiency be low, but also a series of problems such as load swing, start-up shock and inaccurate positioning may occur.

Only when one is strong enough can they lift the weight of a thousand pounds

In application scenarios with large-tonnage loads such as bridge cranes and gantry cranes, the requirements for the drive system are extremely strict. The EDM lifting drive device and motor of EED are specifically designed to address these challenges.

High starting torque, stable! Instantly overcome the huge static friction force

What is the most feared thing in lifting operations? "Can't lift it up" and "Start the first charge". When heavy objects are at rest, they require tremendous force to overcome inertia and friction. If the driving torque is insufficient, the motor will either remain motionless or make a lot of noise but lack power.

The EDM lifting drive device developed and manufactured by EED features a very high dynamic speed-torque axis, ensuring high starting and braking torque. This means that in the moment from 0 to 1, it can output peak torque, smoothly lifting a 40-ton cargo from the ground, effectively avoiding starting difficulties or impacts caused by insufficient force, and ensuring the safety of the equipment and the cargo.

Double-sided safety braking, stable! Bid farewell to the trouble of "wavering"

One problem that troubles professionals in the industry is that heavy objects swing in the air, which not only affects the placement accuracy but also poses a huge safety risk. This largely depends on the reliability of the braking system.

The EDM lifting drive device of EED brand is equipped with double-sided safety brakes, which can achieve safe braking and effectively prevent load swing. Compared with single braking, this design provides double protection, which is like giving the crane a "double insurance". When the motor is powered off or comes to an emergency stop, the two braking systems can respond instantly, generating powerful and smooth braking force, firmly locking the load, refusing "nodding" and "swaying", making precise operation possible and providing a full sense of security!

Compatible with intelligent frequency conversion control, excellent! Achieve "pixel-level" micro-motions

Modern lifting operations require not only strength and safety but also "precision". For instance, in scenarios such as mold installation and the connection of precision components, a slight mistake can lead to a huge error.

The EDM lifting drive device of EED brand can be seamlessly integrated with advanced control systems such as frequency converters (VFDS) to achieve "soft start" and "soft stop". Through the precise control of the frequency converter, a smooth transition from high-speed descent to slow positioning can be achieved, even reaching millimeter-level micro-motion control. This "fast and slow at will" controllability significantly reduces the operational difficulty and enhances the accuracy and efficiency of the work.

Integrated design enhances efficiency and has strong corrosion resistance

In addition to its powerful performance, the EDM lifting drive devices and motor series products developed and manufactured by EED are also outstanding in terms of structure and environmental adaptability.

In terms of design, the bearing bracket of the drum and the lifting drive gearbox are integrated into one unit, forming a compact structure that requires a small installation space. Such an integrated design also enhances transmission efficiency and structural rigidity. Meanwhile, the casing has a very high corrosion resistance and can work stably for a long time, whether in a humid and salt spray-rich port or in a chemical environment with corrosive gases.

The EDM series lifting drive devices and motors produced by EED Transmission, with their four core advantages of high starting torque, double-sided safety braking, good adaptability to intelligent control, and high integration and durability design, precisely meet the all-round requirements of modern heavy-duty lifting equipment for power, safety, accuracy and reliability.
