Abstract
An apparatus for applying a test load to an article (104) has upper and lower mounting members (10,12) between which the article is attached. The lower member (14) is connected via a girder (52) to a weight attachment plate (56) and beneath the plate is a plurality of weights (A to Z), each having a peg (62) which extends through a corresponding aperture in the plate. A solenoid-actuated collar (80) mounted on the plate (56) is associated with each peg (62), and by appropriate actuation of the solenoids, one or more of the weights (A to Z) may be releasably attached to the plate (56). The selected load may be applied to the article under test (104) by actuation of a fluid-operated ram (48) which displaces the upper mounting member (10) upwardly.
Claims17
A load testing apparatus comprising:
- (a) first and second article mounting members between which an article to be tested is releasably securable;
- (b) a weight attachment member to which one of said mounting members is connected;
- (c) a plurality of weights disposed beneath said weight attachment member;
- and
- (d) attachment means for releasably securing one or more of said weights to said weight attachment.
A load testing apparatus comprising:
- (a) upper and lower article mounting members between which an article to be tested is releasably securable;
- (b) a plurality of weights disposed below said lower article mounting member;
- (c) a weight attachment member attached to said lower article mounting member and disposed between said lower article mounting member and said weights;
- (d) attachment means disposed on said weight attachment means for releasably securing one or more of said weights to said weight attachment member;
- and
- (e) displacement means for displacing the upper and lower article mounting members relative to each other, thereby to subject said article under test to the weight of said weights attached to said weight attachment member.
