CAP WINS NATIONAL COMPOSITES "ACE" AWARD!!!! (844) 344-2271 email@example.com
No need for cranes, crane operators, crane guides, and an operator to steer the frame over the hole. Use those other employees and equipment to lay pipe...where you make money! And lower your workman's comp.!
In addition to avoid sticking to the frame due to corrosion, CAPs are half the weight. They won't fly out, but they can be removed with basic tools and a tug. Superman is not needed! Victoria Hinojosa, Miss Texas USA, shows us how it's done.
Video demonstrates common struggles and handling risks that municipal operators face every day: extremely heavy traditional covers impose risks of back, toe, and finger injuries. CAP's are half the weight. No special tools are needed...neither is Superman. Click "Play" arrow to see the video.
$700,000 to over $1,000,000 per year is the cost of back strains lifting manhole covers for just one medium-sized utility operation. This incredible data was given to CAP recently by a utility engineer; each incident costs $70,000, and they have 10-15 incidents for strains lifting covers each year. CAP composite covers weigh half to one-third of current covers and should certainly reduce, and hopefully eliminate, this issue.
"...it becomes clear that manual lifting of (cast iron) manhole cover is extremely hazardous and has the potential for inflicting very serious injuries."

This type of lifting assist is a must for safe traditional manhole cover lifting. But the average cost of $1,200 per unit and set up time should be considered as part of the added cost. Plus, these devices do not address initial movement on and off a truck bed, but merely hole maintenance activities.
Manhole covers and frames can weigh as much as 350 lbs each. This introduces obvious safety concerns for workers as well as slow installation with special machinery. CAP traffic-rated, Made-In-USA, ACE award winning, composite manhole cover assemblies are typically less than 1/3 the weight of iron assemblies. This video shows a contractor installing a traditional frame using a crane. Devote more of your crew to laying pipe and less to setting manholes. CAPs can be set with only one worker.
" ...over 36 percent of injuries involving missed workdays were the result of shoulder and back injuries. Overexertion and cumulative trauma were the biggest factors in these injuries."

O.S.H.A. (29 CFR 1910.146) requires special procedures for confined spaces and describes a portal exit 24 inches or less "Restricted" for rescue service (Appendix F) . Since most standard manholes are 22 to 24-inch clear openings, the future holes will be larger than today's. 30-inch clear openings are now mandatory for new manholes in Texas, New Hampshire and an increasing number of states.
Density of Cast Iron= 7.2 grams/cubic cm
Density of Composite = 1.8 grams /cubic cm
That means for the same change in the cover volume, the already heavier iron cover will increase 4 times more than the composite!!
Example: 125 lbs 26" iron cover might increase to 205 lbs for 32" cover while a composite cover of the same dimension would increase from around 75 lbs to 95 lbs - gaining 20 lbs vs. 80 lbs.
