Wireless crane 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 wireless crane control, one of the following two controls was usually used to operate the crane: bridge crane pendant controls or wired suspension controls. Now we briefly introduce and compare the above control methods.
The main points are as follows:
✉ Traditional crane control
✉ Wireless crane control
✉ Wireless crane control VS traditional crane control
Cranes are essential in many industries, including aerospace, automotive manufacturing, chemistry and minerals, pulp and paper, steel production and utilities, as well as grain industry, logging, rail yard and ship handling. Traditionally, industrial cranes are operated by operators sitting in the crane cab. In this case, the operator's actions are guided by the gestures of the personnel outside the crane. In other cases, it is not the operator sitting in the cab, but someone outside the crane using the suspended button station suspended on the crane to operate the equipment.
Traditional crane control mainly includes cab control device or suspension 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.
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.
In recent decades, the technology has developed to the point that the crane can be operated by remote control. The wireless crane control system consists of two units. One is a portable transmitter that generates control signals. The other is a receiver permanently mounted on the crane. The receiver is connected to the control unit of the crane. Each switch on the transmitter creates a specified "pulse" combination and sends it to the receiver, which decodes the "pulse" and sends it to the crane's motor controller.
Wireless remote radio control solves the problem 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.
Then compare their usage in daily work. What's the difference between them?
(1) Improve work efficiency
Operators can not only work safely on the floor, away from danger, but also better grasp the direction of effective lifting. Therefore, in the process of operation, the work efficiency is greatly improved.
Since the control system eliminates the dependency of binding it to the crane through cab control or suspension control, the operator can lift, place or reduce the load without approaching the load, so radio control can help them avoid some hazards.
(3) Cost saving
Since this control system only needs one operator to control the crane from the ground, you no longer need a team of two or three staff to operate the crane from the cab and ground to lift, move and lighten the load through hand gestures, thus greatly saving related costs.
(1) Power supply is not convenient.
Since battery power must be used, the battery must be checked regularly and replaced or charged.
(2) Easy to damage.
Because it is a handheld device, it is more vulnerable to damage. Although it is made of solid plastic and rubber materials, if it falls repeatedly, it will still be damaged and may affect its function.
With the development of related industries, wireless crane control is more and more popular in daily work. Therefore, the wireless crane control system may be the best way to improve each part of crane operation by properly training operators. Because in many cases, wireless control makes the work safer, faster and more efficient.
