How do you use your overhead crane remote control?

Mobile cranes have been developed to incorporate a variety of different mechanical systems in order to lift and move large loads. One of the main mechanical tasks of the cranes is the remote control and controller, among others. Our extensive experience in lifting remote control equipment and controllers has given us a deep understanding of how cranes or hydraulic crane arms work so that we can better serve our customers in various industries and other companies with lifting controllers. You can read this article to learn more.

This passage is going to talk about the followings of overhead crane remote control:

  •  Factors affecting the accuracy and use of overhead crane remote control

  •  Make your work easier

  •  Conclusion


1) Factors affecting the accuracy and use of overhead crane remote control

1. Directionality - At moderate distances, the IR system requires the operator to "aim" the handheld device in the direction of the receptor. If on a crane, it is oriented toward the bridge and upward. The most important operational issue introduced is that the operator must divide his attention between thinking about constantly aiming, and moving the object involved. 2.

2. Range - IR has a very limited reliable range compared to RF. IR tends to become intermittent at distances greater than 100 feet.

3. Sunlight - The infrared component of the sun can interfere with the IR signal. The receiver must be shielded from the sun. When used outdoors, the receiver must be installed to avoid direct sunlight or reflection. This is especially difficult at dawn and dusk and in very bright and reflective environments.

4. Weather - Infrared light can be weakened by dust, smoke, rain and fog, which can greatly reduce the operating range The receiver lens, which must be cleaned frequently and protected from rain, frost and ice to avoid further attenuation of said signal.

5. Cluttered operating environment - Unlike RF, IR requires line of sight from the transmitter to the receiver. If there are vehicles and other obstructions between the transmitter and receiver, the operator will not be able to control the device.

6. Emergency Stop Response - In an emergency situation, the operator must send an emergency stop command before acquiring the receiver to delay shutting down the device.


2) Make your work easier

Crane operation has always had two simple goals: to put the crane at the load and then move the load somewhere; and to do so safely and efficiently. In the past, the movement of the crane was driven either by the operator mounted in the cab through the floor walker's hand signals, or by a push-button pendant suspended from the crane and controlled by a person on the floor.

Today, a third method has emerged for remote crane operation, especially through radio signals (understand radio versus infrared) is becoming increasingly popular because it overcomes many of the practical problems of crane operation and control.

Consider the cab-mounted operator whose main job is to move the crane. The person may be able to work alone, using attachments below the hook (such as magnet grabs or C-shaped hooks) to manage certain operations. However, the vast majority of loads require assistance on the floor for rigging and positioning orientation. Both of these activities slow down the movement of the crane, and the well may involve some safety hazards.


3) Conclusion

Although suspension control by making the crane control closer to the load to solve some of these problems, but there are still problems. The pendant is on the wrong side of the crane half the time, even if it can easily cross the bridge. Or the pendant can fall off the hoist. Either way, operators will find that dodging the load and unhooking the cable becomes time-consuming and somewhat dangerous. Although floor walkers simplify the job by guiding the operator through hand signals or voice radio, the crane's movement still slows down at the operator's pace. Wells and walkways must also be available.

Using remote radio control avoids most of these problems because it allows the operator to control the position of the crane from any point on the floor that makes the most sense for safety and efficiency on the left side of the load on a truck, in a railcar, behind the load, or on a rack or stand. This allows for more efficient This allows for more efficient use of operator and crane time.
