Details for Rubber Speed Humps

While speed humps are a relatively common device found in parking facilities worldwide, does anyone really know what it takes to create one?

For a rubber speed hump, there are several components that are installed together to create one, cohesive structure.  First, the primary portion of the speed hump would be the interior sections.  Each individual middle section of speed hump is 35.5″ x 19.5″ x 2.10″.   Keep in mind that the 35.5″ measurement is actually the length of speed hump that the vehicle will cross over as it drives over the speed hump.  And 19.5″ is the width (side to side).  As you place one piece next to another, the speed hump width across the road will increase by 19.5″.

These weigh 32 lbs each and can be stacked 49 per pallet or packaged in individual boxes for shipping.

Each section is designed with a tab on one side and an opening on the other so that when they are placed side by side, they will interlock with a tongue & groove system.  They also contain yellow reflective tape in a stripe pattern to make them extremely visible and truly hard to miss.

The next component is the end cap.  This end cap is created with a taper to decrease the size from the highest point of 2.1″ down to just 0.25″.  This taper added to the ends will help several things.  When end caps are missing, the last section of speed hump allows a blunt end of 2.1″ to be exposed.  People walking by may tend to trip over this exposed end.  If end caps are added, this blunt end is covered and pedestrians are less likely to trip over the 0.25″ area that is remaining.

In addition, when speed humps are installed, inevitably, vehicles will try to drive around them.  The end cap serves two purposes.  First, it can cover the last bit of distance between the end of the hump, and a curb next to it.  Plus, it will also protect the end of the hump.  If a car drives over the exposed end of a hump, the pressure exerted on the very end is significant compared to the pressure exerted on each of the interior sections.  This pressure, over time will break down & deteriorate the end.  The end cap will protect this end and even the pressure so vehicles are less likely to damage the product.

And the final component is the lag bolt & shield anchoring system.  To install, a hole is drilled into the surface.  A shield is slipped into the hole to give the bolt something to grip.  The hump is aligned with the holes, the lag installed, and piece by piece anchored to the surface.

Once the entire speed hump is installed, this will help to control traffic to a 10 – 15 mph range.  These are designed to slow traffic, not stop it completely.  So they should be used in areas where traffic must stay moving, but moving at a slower rate of speed than current.  A good example would be in a parking garage, at entrances that are close to major road ways, or on side streets.

The final product is a durable, easily removable, speed hump that will deter speeding, and protect the environment and pedestrians surrounding it.
