Abstract
A truck scale has a weighbridge built with two parallel beams for carrying the wheels of a truck. The beams are laterally interconnected, and are each narrower than half the width of the weighbridge, so there is a gap at the center between the beams. Each beam rests directly on load cell devices supported by foundation members. In very long scales each beam is composed of shorter sections, each supported by a pair of load cell devices. The gap in the center of the weighbridge is covered by removable cover plates or blocks, which may have side walls extending above the beams to limit the lateral travel of truck wheels on the scale.
Claims15
Truck scale for weighing over-the-road vehicles supported by pairs of wheel units, comprising:
- (a) a pair of narrow beams, each narrow beam having a top surface that is wider than one of said wheel units and adapted to directly support a wheel unit;
- (b) interconnecting means for rigidly spacing said narrow beams apart to form a weighbridge with a gap in the middle;
- (c) a plurality of load cell devices arranged to directly support each narrow beam;
- and
- (d) foundation means for supporting said load cell devices.
Method for constructing a truck scale for weighing over-the-road vehicles supported by pairs of wheel units, comprising the steps of:
- (a) providing foundation members for the scale;
- (b) providing a pair of narrow beams, each narrow beam having a top surface that is wider than one of said wheel units and adapted to directly support a wheel unit;
- (c) providing load cell devices for supporting each of said narrow beams on the foundation members;
- (d) providing rigid cross braces for interconnecting the pair of narrow beams;
- (e) interconnecting the pair of narrow beams to form a weighbridge with a gap along its centerline;
- and
- (f) mounting the pair of narrow beams on said foundation members directly via the load cell devices.
Truck scale, comprising:
- (a) a pair of narrow beams;
- (b) interconnecting means for rigidly spacing said narrow beams apart to form a weighbridge with a gap in the middle;
- (c) a plurality of load cell devices arranged to directly support each narrow beam;
- (d) foundation means for supporting said load cell devices;
- and
- (e) cover means for removably closing said gap between the narrow beams.
