In the mechanical industry, bridge crane is widely used. Bridge crane is a kind of lifting equipment, which is used to lift materials horizontally in workshop, warehouse and storage yard. The bridge of the bridge crane extends longitudinally along the track laid on the viaduct on both sides, which can make full use of the space under the bridge to lift materials without being hindered by the ground equipment. It is the most widely used and the largest number of lifting machinery. With the development of related industries, bridge crane pendant controls has become a thermal control method.It is a type of pedant crane control. Do you know what is the bridge crane pendant controls device? What are the advantages and disadvantages? Now, we have a brief introduction and analysis of this, hoping to help you better understand.
The main points are as follows:
✉ What is bridge crane pendant controls
✉ Characteristics of control technology
✉ How to check the control system
The bridge crane consists of a bridge moving between two fixed runways. A bridge is usually designed as a single beam or a double beam with a trolley traveling along the span of the bridge. The runway can be installed on the existing building support, independent crane support structure or hanger. Bridge crane is the main force. Because of its large production scale and wide use, it is widely used in warehouses, yards, docks and other places. Suspension control of bridge crane is a way to control this kind of crane through suspension control. This control mode is designed to transport goods from one place on the ground to another. Its main function is to lift and carry all heavy objects through lifting tools. And the displacement of its object can be horizontal or vertical. This method can prolong the service life of the equipment, reduce the maintenance cost, and enable the crane operator to complete the work safely and effectively, so as to improve the performance, safety and output.
Compared with other control methods, what are the outstanding characteristics of bridge crane pendant controls?
(1) It can prevent the operator from lifting the load to the maximum capacity, minimize the load swing, prevent the motor from overheating and limit unsafe program modification.
(2) By reducing the high starting current characteristics of AC induction motor, they will minimize the impact on crane and load.
(3) They provide a variety of operation modes and options for the crane or crane operator.
If overhead cranes are used for material handling, it is important that a preventive maintenance plan be implemented in accordance with the crane manufacturer's recommendations. The maintenance procedure shall be centered on a thorough and effective safety inspection plan to be carried out on a regular basis. If the crane inspector finds the components deteriorated or unsafe during the required inspection, they must be repaired before any worker can continue to use the system. Therefore, in our daily work, how do we properly maintain this control system?
(1) Confirm that the button suspension control is not damaged (check for cracks, torn parts or missing labels).
(2) Ensure that all button controls operate normally and move in the correct direction.
(3) When releasing the control in the up or down position, please check whether the drift of the hook is small.
Effective daily safety inspection is very important for the maintenance of any bridge crane system. If any fault, abnormal noise or movement is found during the inspection, please stop using the crane immediately.
After reading this article, I believe you have learned more about the bridge crane pendant controls. Only when you know something can you use it better. After use, strict maintenance and inspection plans must be developed and followed to ensure the long-term satisfaction of the material handling investment, which is essential.
