F E A T U R E S A N D B E N E F I T S3

Eight leg sizes, ranging from 5/8” to 17’-8 ½”,

plus a full range of accessories means that

Megashor can be assembled into post

shores, towers and trusses of almost

any length, all from standard components.

RMD Kwikform Superslim Soldiers provide

restraint to Megashor and are available in

nine lengths from 3/8” to 11’-9 ¾”. This

gives ultimate flexibility when planning

the sizes of towers and centers of props,

therefore minimizing the need for custom

made equipment.

A unique 180 kip axial load capacity

and high axial stiffness ensures that

Megashor will accommodate the rigors

of heavy-duty falsework, cofferdams,

bridge bearing replacement and facade
