50 Ton Double Girder Overhead Travelling Crane with Rotating Electromagnetic Hanging Beam

1. Product Introduction:

Double Girder Overhead Crane with Rotating Electromagnetic Hanging Beam is a double-girder electromagnetic bridge crane with multiple rectangular electromagnets. The electromagnet is powered by thyristor rectifier and is equipped with a power failure magnetic protection system. The operating mechanism of the trolley adopts the intermediate working system, the electric conduction of the trolley adopts the form of angle steel opening, and the control method is the closed cab control.

When using the electromagnetic hanging beam, the net weight of the electromagnetic chuck should not exceed 8t. It is suitable for lifting long billets, steel plates and other materials. The rated lifting capacity includes the dead weight of the electromagnet and the dead weight of the hanging beam. It relies on the longitudinal movement of the cart running mechanism along the direction of the workshop track, the lateral movement of the trolley and the lifting movement of the electromagnet to work. Our company can carry out special design and manufacture according to the requirements of users. The working class can reach: A5-A8.

The standards of electromagnetic girder cranes can vary according to different manufacturers and models, but generally speaking, they should comply with relevant national standards and regulations. When purchasing and using an electromagnetic girder crane, you need to pay attention to the following points:

Electromagnetic chuck technology: The electromagnetic beam crane adopts electromagnetic chuck technology, which can quickly and stably absorb goods. At the same time, the electromagnetic chuck can achieve precise positioning and stable suspension of goods through magnetic control.

Efficient and convenient: The electromagnetic beam hanging crane can be controlled remotely and does not require a professional operator to operate. On the production line, the use of electromagnetic beam cranes can improve production efficiency and shorten the production cycle.

High safety: Compared with traditional cranes, electromagnetic girder cranes are safer. It can avoid safety accidents caused by problems such as wire rope breakage and steel ball falling off. At the same time, the electromagnetic girder crane also has explosion-proof, dust-proof and other functions, and can be used safely in various harsh environments.

Wide scope of application: Electromagnetic beam hanging crane is suitable for various occasions, such as steel, machinery, non-ferrous metals, logistics and other industries. It can accommodate a variety of cargo shapes and weights and can be customized as needed.

Economical and practical: Although the price of the electromagnetic beam hanging crane is higher than that of the traditional crane, it can significantly reduce labor costs and improve work efficiency, so it has a higher cost performance. At the same time, the maintenance and upkeep of electromagnetic beam hanging cranes are relatively simple and convenient.

2. Parameters:

3. Component:

The Double Girder Overhead Crane with Rotating Electromagnetic Hanging Beam is mainly composed of a box-shaped bridge frame, a hoisting trolley (with electromagnetic hanging beam), a cart operating mechanism, a driver's cab and an electrical control system, and is equipped with a power failure magnetic protection system.

The hoisting mechanism mostly adopts the arrangement of single motor, double reducer and double drum, in the form of double lifting points. The layout of the hanging beam is divided into two types: perpendicular to the main beam or parallel to the main beam. The rest of the form is the same as the QD crane.

The metal structure includes bridge frame, trolley frame and control room. The bridge frame is composed of two main beams, two end beams and other components such as walking platforms and guardrails. The box-shaped structure is adopted, and the main beam bears the weight and external load of the trolley, and has sufficient strength and rigidity. It is a solid plate beam structure with an upper and lower cover plate and two vertical webs to form a closed box-shaped section.

The main beam and the end beam are rigidly connected to ensure the rigidity and stability of the bridge frame. The middle parts of the end beams are connected by bolts and can be split into 2-3 sections for easy transportation. The wheel set of the cart is installed under the end beam, which bears the loads in all vertical directions of the crane.

The trolley frame is a frame that supports and installs the various components of the hoisting mechanism and the trolley running mechanism, and is also a structural member that bears and transmits all the lifting loads.

Fixed hanging beam structure. It is divided into two types: the hanging beam is parallel to the main beam and the hanging beam is perpendicular to the main beam. If the hanging beam is parallel to the main beam, the axes of the two drums are also parallel to the main beam, forming a trolley with a small track gauge and a large wheel base; If the hanging beam is perpendicular to the main beam, the axes of the two drums are also perpendicular to the main beam, forming a trolley with a large track gauge and a small wheel base.

The upper part of the hanging beam is hung on the two hooks of the hoisting mechanism through two pin shafts, and the hanging beam can be raised and lowered smoothly through the lifting and lowering of the hooks. The electromagnet is hung on the pin shaft of the hanging beam through the chain to absorb and lift heavy objects. There can be multiple lifting points under the beam to meet the needs of different hanging objects. The eccentric load is not more than 0.5 meters.

4. Applicable Environment:

Double Girder Overhead Crane with Rotating Electromagnetic Hanging Beam used to transport steel, iron blocks, scrap iron, scrap steel, iron filings and other materials, and to lift long sections, bars, plates, scrap steel, coils, etc.

5. Wearing Parts:

Generally speaking, the parts that are not within the scope of the warranty period are wearing parts. The wearing parts of the double-girder bridge crane are almost the same, such as: lifting wire ropes, electrical switches (excluding frequency converters), wires and cables, conductors, etc. Rope device (electric hoist only).

6. How to operate?

The control room is suspended under the transmission side platform, and the driver's cab has two types: open type and closed type.(Please Click Here To Know More)

7. Why is the electromagnetic chuck easy to break?

After the electromagnetic chuck leaves the factory, there is generally a running-in period of about 60 hours, which is stipulated by the manufacturing factory based on the technical characteristics of the electromagnetic chuck at the initial stage of use.

The running-in period is mainly an important link to ensure the normal operation of the electromagnetic chuck, reduce the failure rate and prolong the service life.

However, due to the lack of common sense in this area or the tight schedule, some users used the machine for a long time during the running-in period, and used it for a long time, ignoring the special technical requirements of the running-in period of the new machine, resulting in frequent early failures of the machine.

Therefore, full attention should be paid to the use and maintenance of the electromagnetic chuck during the break-in period.

The main reasons for the burnt out of the electromagnetic chuck motor are as follows:

Ⅰ. In addition to the lack of phase, the reasons for the burning of the lifting motor include:

(1) The load is too heavy;

(2) The motor bearing is damaged;

(3) The brake is not working. During operation, whether it is disengaged or the electromagnetic coil is not in good contact, sometimes the power is cut off, and the brake drum is locked.

Ⅱ. Reasons for lack of phase:

(1) The contacts of the contactor are frequently activated and ablated quickly, and the contact spring and the plastic at the contact are burned and deformed, which will make the contact position insufficient and cause phase loss.

(2) The fuse is too small to cause fever, blown phase and lack of phase;

(3) The lack of phase caused by poor contact of the power supply;

(4) Poor contact of the incoming wire of the motor;

(5) Install an automatic circuit breaker with high agility and a thermal overcurrent protector, and install a phase loss controller to effectively prevent it.

8. Frequently Asked Questions

(1) Do you have engineer oversea installation service?

Yes; we have;

(2) What kinds of products do you have?
