Tips To Avoid Electrical Hazards When Using An Overhead Crane

If you commonly work in construction zones, then you know that safety is one of the most important considerations on the work site. While you may already be aware of the way to use a skid steer, bulldozer, or dump truck safely, you may not know about the best ways to stay safe when using an overhead crane. Overhead cranes may sometimes be needed to move the heaviest and biggest pieces of construction materials from one space to another. If you are new to using a crane, then make sure that you avoid electrical hazards that may cause electrocution. While safety and general crane usage training may touch on a variety of safety concerns, make sure to keep the following tips in mind as well to keep first time crane usage mistakes at bay. Set Up a Danger Zone If you usually work on the ground with loaders and dozers, then electrical lines are likely not a consideration of yours. This is especially true since most of the wires will sit between 10 and 12 feet above your head. This height may be the same or a bit lower than your overhead crane, especially if you are using a boom truck or moving materials several stories above ground level. This means that close electrical lines on your work site are an electrocution hazard. To keep electrocution concerns at bay, you will need to set up a danger zone around the electrical lines. According to OSHA, a 10 foot perimeter must be set around electrical line areas. It can be difficult or impossible to secure a barrier that is tall enough to prevent the passing of the overhead crane near electrical lines. You should make sure the danger zone is clearly marked though with a regulation OSHA danger sign that is red, white, and black. This sign, as well as yellow and black hazard tape should be secured to construction fencing. This will help to make sure that the danger zone is clear and properly marked so you can avoid it when using the crane. Use Wireless Controls Overhead cranes allow you to use a variety of different controls to move booms, the crane itself, and attachments that grip, lower, and raise loads. Typically, the controls are wired to the actual crane to allow for quick and accurate movements. However, this wire provides a direct route for electricity to flow from the power lines, to the crane, and directly to your body. This will happen since the electricity will seek a path to a grounded or stable space. This space is the earth, and your body will let the electricity move there. While rubber gloves and boots can prevent an issue like this from occurring, these items can easily be forgotten. You should instead invest in wireless controls for the crane you are using. This way, there is no path for the electricity and electrocution will not be an issue. Wireless controls usually come with the handheld digital remote control as well as a receiving assembly. The assembly along with the antenna are attached to the electrical components of the crane and a digital signal is sent from the antenna to the remote control. These devices usually have quite a long range. Typically, you can stand several hundred yards away from the crane and expect the controls to work properly....

Overhead Crane Modernization: A Good Strategy For Your Warehouse

Posted by on Jun 26, 2015 in Uncategorized | Comments Off on Overhead Crane Modernization: A Good Strategy For Your Warehouse

When an overhead crane is installed in a warehouse or distribution center, it’s usually there for the long run. It’s not out of the ordinary for warehouses to get decades of service out of their long-term investments, both for reasons of economics and pragmatism. So it only makes sense to explore the possibility of modernizing your overhead cranes, as opposed to purchasing and installing brand-new lifting equipment. Overhead crane modernization sidesteps the cost and downtime issues caused by new equipment installation, while ensuring the safety and productivity of your workforce and overall warehouse operations. The following goes in-depth about the benefits of overhead crane modernization and what the process itself entails. Why Modernize Your Overhead Cranes? There are plenty of good reasons why modernizing your existing overhead cranes makes more sense than undergoing the capital investment required of brand-new lifting equipment: Longer service life – This is perhaps the most appealing benefit of modernizing your overhead cranes. Adding new components to your existing lifting equipment can easily extend its lifespan by several decades. This is a great benefit if you want to get the most out of your existing overhead cranes. Improved cost effectiveness – The complete replacement of a 25-ton two-girder overhead bridge crane with a 50-foot span could run as much as $85,000, factoring the cost of materials and the labor needed for assembly. Modernizing your current equipment, on the other hand, can cost a fraction of that amount. Higher levels of efficiency – Not only can modernization extend the overall lifespan of your current equipment, but it can also make your equipment operated with greater efficiency. As an example, replacing your current load brake with a regenerative model can help boost lifting performance and reduce the amount of energy expended during a typical lifting operation. Quicker turnaround times – High-volume operations can easily be hobbled by the downtime necessary for lifting equipment to be dismantled and completely replaced. Instead, your warehouse or distribution center can opt for modernization as a way to reduce downtime, especially when peak production periods demand little to no slowdowns for maximum profitability. Improved safety – Modernization also gives you the opportunity to bring your equipment back in compliance with current OSHA safety regulations. By getting rid of functionally obsolete and worn-out components and replacing them with newer, safer and more modern counterparts, you’ll improve the overall safety of your operators and other employees. You’ll also rest easier knowing that lifting equipment is no longer in danger of being pushed past its operational limits due to aging components. What Needs to Be Modernized? As The Fabricator Magazine points out, the basic steel structure of an overhead crane is likely as good today as it was 25 or even 50 years ago – these structures are designed to withstand great levels of stress and, as a consequence, last for ages. However, many of the other components that make up the overhead crane, including the end trucks, wheels, hoists, motors and electrical elements, may need to be cycled out. Modernizing overhead cranes means more than just refurbishing and replacing existing components. It also gives you an opportunity to upgrade your equipment with the latest technological advancements on offer. For instance, adding variable-frequency drives to your overhead crane gives operators more fine-tuned control during maneuvers....
