When using cranes on a construction site, there are two things that you need to give precedence. The first one is safety. Cranes are high-risk machines that pose many operational and health hazards to your workers and other people within the vicinity. Secondly, cranes can be quite expensive to hire and maintain depending on the type of work you are doing or the period that you'll need them. Therefore, you must maximise productivity by monitoring the performance of the machine very closely. Otherwise, you won't get the everything that you could with that money. With hoist inverters, you achieve both of these objectives in the following ways:
Detection of Brake Slip
Crane hoists come with brakes to regulate the movement of the load or hold it in place in case of an unprecedented emergency. During operations, brake slips can easily occur and jeopardise the safety of the workers. This happens because of insufficient torque, in which case the hoist inverters sends electric current to the hoist motor, prompting it to hold the load. Moreover, the inverters also trigger an alarm that alerts your workers of an impending brake failure. They can then lower the load safely to the ground to avert dangerous consequences.
Steady control of the load is necessary for safe operation of a crane. Heavy loads dangling and swinging on the crane slings can injure workers or hit against equipment and property, leading to lots of damage. Hoist inverters in cranes help to regulate the motion of the load, keeping it in the preferred position for ease of handling even by inexperienced employees. Ideally, hoist inverters let the operators pay attention to their surrounding and find the most appropriate route for the load they are hoisting.
As much as your workers must keep an eye on the loading capacity of the crane, oversights do occur due to errors of judgement or mechanical problems with weighing scales. Hoist inverters will help you to alleviate the dangers posed by such unprecedented mistakes by detecting overloads and sounding an alarm to alert your operators. The alarms not only ensure safety but also facilitate the efficient operation of the crane by reducing wear and tear on the hoist's slings and crane wheels.
If you have trouble keeping a reliable record of the all the maintenance activities on your crane, the least you can do is to ensure that you detect impending mechanical issues in good time. Hoist inverters help you monitor your crane system for early detection of problems such as overheating motors.
