PRODUCT DESCRIPTION

New Hardware

The Osprey Southwest Safety Umbrella Sign System is a work-zone traffic control device. The device consists of a base structure, a two (2) piece mast, an umbrella canopy, two (2) vinyl flags, and two (2) aluminum signs.

The base structure consists of a PVC pipe mounted on a 21.0 in. (533 mm) by 24.0 in. (610 mm) rubber pad. The base structure has a break away feature located 4.0 in. (102 mm) from the bottom of the base. The mast consists of two (2) 1.5 in. (38 mm) diameter aluminum tubes with 0.1 in. (2 mm) wall thickness. Two (2) 24.0 in. (61 0 mm) aluminum signs are attached to the mast assembly via a swiveling mount. The aluminum signs are mounted 84.0 in (2.1 m) from the ground. The umbrella canopy mounts to the top of the mast assembly and measures 65.5 in. (1.7 m) by 65.5 in. (1.7 m). Two (2) 24.0 in. (610 mm) vinyl flags are mounted to the top of the umbrella canopy. When assembled, the Safety Umbrella Sign System stands 125.0 in. (3.2 m) tall from the ground to the top of the vinyl flags.

The Safety Umbrella Sign System weighs 59.0 lbs (26.8 kg). Forth is test, one (1) 22.0 lb. (10.0 kg) sandbag was placed on top of the device's base structure. The total weight of the as-tested test article including the sandbag is 81 .0 lbs (36.7 kg).

CRASH TESTING

A brief description of each crash test and its result:

Required Test Number Narrative Description Evaluation Results
3-70 (1100C) Test 3-70 was not performed due to the work-zone traffic control device weighing less than 220 lb (100 kg). PASS
3-71 (1100C) The impact with the Safety Umbrella Sign System did not cause any significant damage to the vehicle and did not create a hazard to the driver. Upon impact, the test article yielded and the breakaway was activated. Test article debris was contained within the vicinity of the impact area. The test vehicle remained upright and did not leave its lane. PASS
3-72 (2270P) The impact with the Safety Umbrella Sign System did not cause any significant damage to the vehicle and did not create a hazard to the driver. Upon impact, the test article yielded and the breakaway was activated. Test article debris was contained within the vicinity of the impact area. The test vehicle remained upright and did not leave its lane. PASS

Full Scale Crash Testing was done in compliance with MASH by the following accredited crash test laboratory (cite the laboratory's accreditation status as noted in the crash test reports.):

PRODUCT DESCRIPTION

Modification to Existing Hardware Non-Significant-Effect is positive or Inconsequential

The Osprey Southwest Safety Umbrella Rolling Base Structure is a work zone device to assist in keeping our Safety Umbrella in the upright position when in use and will allow the Safety Umbrella to be moved around the work zone without having to lift the umbrella and carry it to a new location. The device measures w: 24" × d: 27.5" × h: 4" and weighs 211bs with 2 wheels that sit ½" off the ground and are mounted to the end of the structure. Material: Steel.

The center of the device has a 4" high round post (Breakaway Feature) that will allow for a 2" diameter PVC post that the safety umbrella slides into. Welded on to the side of the 4" high center post is a threaded knob that screws through the PVC post and applies pressure to the umbrella pole to stabilize.

Variations to the successfully crash tested Rubber Base would be that the crash tested base weighed 561bs which included a 20ib sand bag and was made out of a rubber mold with a metal center post almost identical to the 211b Rolling Base Structure. Also, the rubber base had a slide through pin that ran through the entire PVC post to keep in place. The Rolling Base Structure is actually designed better so that if it is ever run over the PVC will breakaway at the same location as the Rubber Base but in an easier, faster motion. The Rolling Base Structure does require a 40ib sand bag for added support and "Likeness". To note, when analyzing both bases they are almost identical in design at the breakaway point where they should react in the same manner.

KARCO ENGINEERING ANALYSIS: We spoke about the new design here and we think that the changes should not affect the way the sign reacts to an impact as long as the base is still weighed down with sandbags. We used a 20 lb bag for the rubber base, making the base plus sandbag approximately 56lbs. For the lighter weight rolling base I would actually suggest using a heavier sand bag; maybe a 40 lb bag. This would also increase the "likeness" between the two designs.
