Marston mat design origin carnegie steel 1941 corp of engineers video transportable runway youtube.
The steel mat came in rolls of interlocking 10 foot sections which were ringed with hooks and slots for easy assembly by strong men using sledgehammers.
In the mid 1960s u s.
The psp landing mats are cheap light absorbing big forces and made for multiple use.
Marston mat s compact dimensions and relatively light weight made it easy to ship and to carry.
Stained and lightly oiled or.
During testing the crosslam mat collapsed with a weight of 58 411 lbs while the fir bolted mat crumbled at just 25 550 lbs.
Wired into bundles and subbundies 375 square feet of runway surface stood only twenty eight inches high.
A completed airstrip ran 3 000 feet long and 150 feet wide.
At the point of collapse the fir bolted mat flexed 8 88 while the crosslam access mat only flexed a mere 1 60.
Our material handling section includes everything from military aircraft landing mats to 600 gallon aluminum tanks.
Each plank was 10 feet 3 05m long 15 inches 38 1 cm wide and 0 25 inches 6 4mm thick and weighted 70 pounds 32 kg.
Developed in the early 1960s am 2 is an extruded aluminum mat that is 3 8cm 1 5in thick comes in a nominal 0 607m x 3 66m 2ft x 12ft panel size and weighs roughly 310 1n m2 6 46lbs ft2.
Storage trailers loading dock ramps and even military surplus forklifts are available.
The transport requirements for am 2 are very taxing requiring 48 dedicated c 130 aircraft sorties for a standard 18 580 6m2 200 000ft2 parking apron2.
This mat has a solid surface strengthened by corrugations that also encouraged the drainage of rainwater.
There is something for everyone in this unique military surplus category.
This was made as a hollow extrusion rather than pressed.
The mat size also changed to be 22 by 144 inches 560 mm 3 660 mm.
Navy engineers built on the concept of the xm 19 mat s solid surface and honeycomb core and combined it with the traditional size and shape of previous matting.
Each mat was pierced with 87 holes to allow drainage which also reduced its weight to 66 pounds per section.
Marston mat was best laid on 12 to 18 inches 30 to 45 cm of crushed rock or coral but in a pinch it was laid directly on ground as unstable as arctic bog.
Tivo men could pick up a piece and run with it.
Independent testing shows crosslam access mats are more than twice the strength of bolted mats.
