With the development of related industries, cranes have been widely used. Various crane control devices have been invented and used, including wireless crane control, pedant crane control, bridge crane pendant controls, etc. So, how do we choose the right crane control equipment? We should consider not only the price of the crane, but also the quality. Although there are many crane controllers that are reasonably priced, cost alone does not determine your application. So, how to choose the appropriate crane control device? Now, we will give a brief introduction to this, hoping to help you make a better choice.
Wireless crane control
Pedant crane control
The wireless crane control device solves the problems of cab and cable suspension control, and provides the advantages of both. Operators can perform assembly and guidance tasks on the floor, so operations require fewer workers to complete other tasks. The operator can also have a better view because he or she can move to a position on the floor that will provide the best view of crane operation and may not require other observers or repeaters.
Wireless control also enables the operator to move the load closer to the load in a safe position, thus obtaining higher accuracy during operation. In case of heavy load or dangerous load, the operator can also stay away from the load to make the operation safer. Unlike wired suspension controls, wireless controls do not limit the operator's position relative to the load or require the operator to move with the load. The operator must still observe and keep away from the falling area. In case of an accident, the load may fall and fall onto the person.
Because radio control devices are wireless and not connected to a power source, they are powered by batteries and must be checked and replaced or charged regularly. If the crane is not inspected, the operator will find that the crane cannot be used when required due to the need to use the control battery. If radio control equipment is misplaced or left in the path of heavy equipment, they may also be lost or accidentally damaged. Another less common disadvantage is the possibility of radio interference. This disadvantage is a problem only in specific applications where the environment creates its own radio waves. If there is a separate electromagnetic radiation source, these waves may interfere with the control equipment and destroy the communication between the equipment and the crane. Wireless control systems are also generally more expensive than cab and cable suspension control systems, but with the improvement of wireless technology, the price gap continues to narrow.
Wireless remote radio control is a new choice for crane operation. Compared with traditional crane control, it has many advantages. These benefits include safer operation, better maneuverability and longer working hours. Before the rise of radio controls, one of the following two controls was usually used to operate the crane: Cab controls or wired suspension controls. These two controls are included in the footrest control.
(1) Cab control device
Cab control device and wired suspension control device have some disadvantages that wireless control device solves. The biggest problem with cab controls is that most applications require more than one person to complete. Crane operators usually need help on the floor to lift and place goods, and many operations need point inspectors or relay operators to guide operators through visual or verbal instructions.
(2) Wired suspension control device
The wired suspension control solves these problems by placing the operator on the floor close to the load. The operator can lift and place the cargo, and the possibility of direct aiming can eliminate the need for a sample dispenser. But the wired pendant control also has some disadvantages. They require the operator to follow the path of the crane along the floor, which may increase the risk of tripping or falling, and may slow down the operation if the crane moves faster than the operator can walk safely.
The wired suspension control system also requires the operator to remain close to the load at all times. This method is particularly dangerous when working under heavy or dangerous loads, which increases the risk of injury to the operator. Operators must avoid loads and be careful not to tangle cables, which is unsafe and time-consuming.
After listening to the above introduction, do you have a further understanding of some existing crane control equipment? Wireless crane control and pedant crane control have advantages and disadvantages. I hope you can choose the right control equipment according to your own needs and actual situation.
