Abstract
Abstract An apparatus for weighing transport vehicles in motion, wherein at least two measuring units are electrically connected with a recording unit, each comprising a load platform which bears on a dynamometric pickup load cell at a supporting point and is connected to a supporting structure by means of four rods installed in pairs at two sides of said load platforms, directed to one end thereof and secured at one end on said supporting structure and at the other end on the side surfaces of the load platform in immediate proximity to the geometric line which is a projection of the vertical line through the supporting point of said platform onto the respective side thereof, said load platform bearing on the load cell at a geometric point whose vertical displacement due to an arbitrary moment of forces acting upon the load platform and causing elastic deformation of the rods is equal to zero.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
189 words
An apparatus for weighing transport vehicles in motion, wherein at least two measuring units are electrically connected with a recording unit, each including: a supporting structure; a load cell mounted on said supporting structure; a load platform bearing on said load cell at a supporting point; four horizontal rods installed in pairs at two sides of the load platform, directed to one end thereof and secured at one end on said supporting structure and at the other end of the side surfaces of said load platform in immediate proximity to the geometric line which is a projection of the vertical line through the supporting point of said load platform; said rods featuring rigidity which is substantially greater in a horizontal direction than in a vertical direction; said rods being connected with said supporting structure and said load platform in such a manner as to form, in conjunction therewith, an elastic parallelogram; said load platform bearing on said load cell at a geometric point whose vertical displacement due to an arbitrary moment of forces acting upon the load platform and causing elastic deformation of the rods is equal to zero.
Claim 2
Independent Claim
189 words
An apparatus for weighing transport vehicles in motion, wherein at least two measuring units are electrically connected with a recording unit, each including: a supporting structure; a load cell mounted on said supporting structure; a load platform bearing on said load cell at a supporting point; four horizontal rods installed in pairs at two sides of the load platform, directed to one end thereof and secured at one end on said supporting structure and at the other end of the side surfaces of said load platform in immediate proximity to the geometric line which is a projection of the vertical line through the supporting point of said load platform; said rods featuring rigidity which is substantially greater in a horizontal direction than in a vertical direction; said rods being connected with said supporting structure and said load platform in such a manner as to form, in conjunction therewith, an elastic parallelogram; said load platform bearing on said load cell at a geometric point whose vertical displacement due to an arbitrary moment of forces acting upon the load platform and causing elastic deformation of the rods is equal to zero.
Claim 3
Dependent Claim
92 words
An apparatus for weighing transport vehicles in motion, as claimed in claim 1, wherein each of said measuring units further includes: a spring installed between said load platform and said supporting structure and adapted to be moved on the surface of said supporting structure with respect to the supporting point of said load platform for said supporting point to coincide with the load platform geometric point whose vertical displacement due to an arbitrary moment of forces acting upon said load platform and causing elastic deformation of said rods is equal to zero.
Claim 4
Dependent Claim
60 words
An apparatus for weighing transport vehicles in motion, as claimed in claim 1, including: said load cell mounted on the surface of said supporting structure movably with respect to the load platform geometric point whose vertical displacement due to an arbitrary moment of forces acting upon said load platform and causing elastic deformation of said rods is equal to zero.
