1. A vibrating screen comprising:
- a support structure which is configured to be transported on a highway and is configured to be adjusted to variable angles;
a vibrating screen configured for sorting aggregate by size;
a pair of springs, each of said pair being coupled to both said support structure and said vibrating screen;
a dual pivot damping system configured for damping vibration in two orthogonal axes;
wherein said dual pivot damping system comprises;
a screen connection;
on said vibrating screen;
a base connection on said supporting structure;
a plurality of pivoting leg members coupled in series between said screen connection and said base connection; and
where a plurality of pivoting leg members are disposed adjacent a readily replaceable member.

Abstract
A compact mobile variable angle vibrating screen with a suspension and dampening system configured to accommodate variable angles and exhibit acceptable vibration levels; especially during power up and power down surge vibration at the variable angles. The system comprises a group of bi-directional dual pivot leg vibration damper mechanisms which are effective only during times of excessive vibration such as during the power up and power down vibration surges.
