Rubber Truck Bumpers for Impact Resistance

Posted October 07, 2015 4:55 PM by Doug Sharpe

Rubber truck bumpers help keep trucks and trailers on the road instead of in the shop. Learn how these impact-resistant bumpers meet ASTM standards, and are available in different types for vehicle protection.

Rubber truck bumpers help protect trucks and trailers as they backup to loading docks, or when a driver opens the truck's side doors. They absorb energy from low-speed collisions and low-force impacts while helping to keep trucks on the road instead of in the body shop. These rubber auto parts cost less than truck body repairs, and are easy-to-install with standard metal fasteners such as screws, bolts, and washers.

Rubber truck bumpers are made from elastomeric compounds that can withstand sunlight, rain, snow, and incidental contact with petroleum products and automotive chemicals. SBR and EPDM rubber are good choices because they can handle these road conditions while providing good tensile strength and abrasion resistance.

Avoid Vehicle Damage

Shippers and receivers who have seen a truck hit a loading dock understand that even at low speeds, a moving vehicle can cause significant damage. In a warehouse environment, repeated impacts or serious collisions can damage the structural integrity of a concrete platform. Trucks and trailers that sustain damage may need to be taken off the road, and that the temporary loss of a revenue-generating asset. Fortunately, rubber bumpers provide a simple, cost-effective solution to help keep your trucks rolling.

Keep on Trucking

Although some truck drivers now use dashboard cameras, maneuvers such as 90-degree alley docking or offset alley docking aren't easy. Broken or uneven pavement, standing water, and poor lighting conditions can also complicate straight-line backing. Collision avoidance sensors in cars may be helpful, but truckers need to do more than avoid a crash. Truckers need to move a trailer as close as possible to a dock while driving in reverse. Rubber bumpers aren't a substitute for driving skills, of course, but they can help to protect your assets.

Reliable Rubber Truck Bumpers

Elasto Proxy supplies 75-durometer (Shore A) rubber truck bumpers to trucking companies, repair shops, and truck body manufacturers. All of the rubber bumpers that we offer have embedded washers and attach with standard fasteners that you provide. Ask our solutions providers about product samples, minimum order quantities, and lead times.

Industry Standards and Rubber Bumpers

All of our rubber truck bumpers meet the requirements of tests from ASTM International, a leading standards organization. The following list contains the specific ASTM standards and properties.

To compare the ASTM test standards to the actual test results, download the spec sheet.

Wow! Impact-resistant bumpers. I remember when they used to put them on cars. Now they're just decorative trim that costs money to replace.

Oh, they still have those impact-resistant bumpers, they're just now six inches BEHIND that decorative and expensive trim.

Because covering a $75 bumper with a $50 'bumper trim' piece that costs the consumer $2,000 to replace makes more money for the auto parts manufacturer than putting on a $150 pumper that can absorb the shock of impact without damaging itself or the car it's attached to.

I've found 3/8" and thicker steel plate to be very impact resistant on my side of the crash.

mount it on a sliding rig, with some shock absorbers to 'steal' the impact energy before it reaches the cabin, and you've got a winning idea there.

Could you add some spikes on the front?

That bumper alone says "If you're smaller than an SUV/minivan, by truck's gonna walk all over you like an elephant squishing an ant." Adding spikes just peppers the message with profanities.

I'm not saying the spikes wouldn't be cool, just that on "polite roads(1)" they're overkill.

Notes:

  1. By which I mean roads where you are NOT likely to see someone driving along with his buddies, all dressed in bondage gear, strapped to the outside of the vehicle. Here in Chicago, the politest roads are only as polite as an Andrew Dice Clay standup routine, when he's reaching for his 'blue' material.

Ah, I see.

By the way, I heard reports about that LoEG limo: looked FANTASTIC, steered like a drunken pregnant cow with three broken legs. The two front axles kept 'fighting' each other, since all the wheels turned in unison, rather than having each wheel turn a diferent amount so the two axles would compliment each other.

Then again, it was designed to be a movie prop, not an actual street-legal car, so why spend money on an expensive, experimental handling system? If it WAS intended to show off its driving, they would have made a 'stunt' car with the front steering wheels not touching the ground, so the car could turn well for the medium- and long shots.

Wow, slap some 'bat wing' tailfins on that puppy and call Tim Burton back to direct.

We can get any actor to fill the suit, all you see anyway is the chin.

What's wrong with two sets of front wheels?

Nothing, if the steering is properly designed for it.

looking at that photo, I can clearly see that the front-front right wheel is turned farther to the right than the rear-front wheel, so the two front axles are working together to turn the vehicle.

The 'Nemo Limo' had it's front axles locked to the same steering, with the same ratio, so, the four tires fought each other for traction, and depending on which one was winning at the moment, that affected how sharp your turn was. Random over/understeering, changing throughout the turn, what fun! (Now if you'll pardon me, I need to go do something undignified in the restroom, not even I can stomach the amount of sarcasm needed to give that last like with enthusiasm.)
