Crane pendant
A Crane pendant is a part of the EOT crane which is used to lift heavy materials or objects. It is also referred to as a crane control unit or crane pendant station. The Crane control unit consider as a main part of the machine because in case of any break down the first person or inspector inspects the machine. The control unit is wired into an electronic machine that is connected to the overhead crane and hung like a pendant that is why it is known as a pendant control unit. The pendant control switch can easily move the crane in a particular direction like up, down, east, west, south, north, etc.
Working of crane pendant push button switch:
The EOT crane pendant comes in various button types. It can be a 2, 4, 6, 8, and 10 push-button switch. As we press the button on the pendant switch it sends the signal to the control unit which is attached to the EOT crane. However using the pendant switch requires two men, one is on the ground floor for guiding while another man is sitting in the cab of the overhead crane and follows the instruction of the first man.
The control unit can be connected to the crane itself or many modern cranes. When the operator uses a pendant control switch then the crane crosses the runaway at that time the operator himself walks along with the control unit because of a wired mechanism. When there was no radio remote for the crane at that time the wired crane system was followed by the industries.
Pros and cons of Pendant switch for hoist:
In a modern time where most of the industries using the wireless remote control for cranes the pendant switch for hoist comes with a wired system so there is a requirement of an operator who can sit in the cabin of an overhead crane and can operate the crane. The main advantage of pendant crane control is that it is a wired system so there is no chance of external interruption. And the pendants are suspended from the hoist so there is no chance of accidentally dropping the control or misplacing it. The pendant control doesn’t require a charging system because it is fully functional on a wired system.
Since it is a wired system so there is a risk for operators who are sitting in the cab of the crane because if there is a heavy-duty load on the hoist where an accidental drop load occurs so will result in potential harm to the operator. There is another potential risk of fatal injury for the operator who walks alongside the crane to monitor and guide the other operator. In between this, the operator is at the risk of tripping, slipping falling onto the risky obstacles. Another risk is that the wire of the crane pendant control switch is directly connected to the crane which can be caught up in the machine that will cause damage to the control system as well as the other crane parts also.
Need of Pendant control:
Pendant push-button control or simply hoist pendant control are directly connected to the crane with the wired and it is used to control the crane from the ground level. To eliminate the need for a guidance operator another type of device is used called a radio remote control that controls the overhead crane from a very far distance. So choosing a wired or wireless control for a crane is up to you.
Conclusion:
For safety and risk avoidance obviously, the data pendant switch is better than other devices. And this kind of pendant push button was built by many industries. But the top-quality crane pendant push-button for the crane is only manufactured from Anand systems engineering private limited. This crane pendant is manufactured in such a way that it can use for a long time and perform well in harsh conditions as well.
