This product is used to safely and effectively
limit movemsnt of equipment components.
Typical application$ could Include:
* \A/orking beams r Traversing crane$
* Cabinets
r Falling
* Forestry vehicles * llt'agons
* Material handling r Lifting cranes

Tiaverse erane with VB Bumper
F---,-+
Features:
Bumper consists of a cylindrical rubber
body which is bonded to a square shaped
steetr baseplate, AII four corners of the
baseplate contain a mounting hole"
A special high memory ruhber is used to
assure as mueh energy absorption as
possible. The volume of the rubber is
used at optimum efficiency"
For new equipment designs simpler and
lighter calculated forces can be considered,
thus achieving a lower sost installation.
