Sometimes when we’re walking on the road, we could see those metal plates on the ground, may wonder why do people put steel plates in the road? Well, today let’s talk about the piece of metal often seen on roads – road plate.
What Is A Road Plate?
Just as the name implies, it’s an essential piece of steel plate forming (part of) a temporary road surface during repair or maintenance for any safe excavation site.
What Are Road Plates Used for?
Road plates are regularly seen when excavations have begun as a preliminary part of construction or repair projects, serving as a temporary solution for covering excavations and allowing roads to temporarily return to service.
They are have a growing place in road construction and areas of public works, for instance in temporary footpath crossings, ramps, crane support platforms, road crossings, manhole covers, surface protection (playing fields, damaged roads etc.) and as covers for open trenches.
How to Secure Steel Road Plates?
In order to work safely, a road plate must be fixed directly in place to avoid any movement. This fixing involves both direct contact with the pavement, as well as pinning, recessing, or securing with asphalt wedges.
Pinning, as the name implies, involves driving pins through steel plates into the concrete to hold the plate in place. Recessing is cutting out the steel plate exactly to the dimensions of the excavation, so that the steel plate rests flush with the pavement.
How Do You Lift HEAVY DUTY Road Plates?
How to Lift steel road plates? There are plenty of road plate lifting devices that people can choose, including hoist rings, chains, plate lifting clamps, magnetic lifters.
For those extra Thick and Heavy road plates weighing up to 500kg-1000kg, or above, magnetic lifter would be a better choice. As road plates are usually placed on roads, where electricity is unavailable, magnetic lifting device should be able to work on their own power. In that case, both permanent magnetic lifter and battery powered permanent electromagnetic lifter are suitable for the job.
One disadvantage about permanent lifting magnet is that its magnetic property tends to recede or weak with time. And that could be a potential hazard during the lift.
With regard to the battery powered permanent electro lifting magnet, it consumes no power when lifting steel plates, just need electric pulse in MAG & DEMAG phase. As to the lifting capacity, it can be customed to lift flat or round steel parts(like large heavy road plate) from 500-5000kg. What more attracting is that, radio remote control is available. Operators don’t have to be near or close to the road plates to perform the lifting job.
