Heavy tool vehicle class strength tester

The invention discloses a heavy tool vehicle class strength tester. The heavy tool vehicle class strength tester comprises a base. A plane conveying mechanism is mounted at the top end of the base. Abarrier is mounted at the top of the plane conveying mechanism. Movable detection mechanisms are mounted on two sides of the plane conveying mechanism. A supporting bracket is fixed to one end of thebase. An up-and-down jump following mechanism connected with a heavy tool vehicle to simulate vehicle load is mounted at the supporting bracket. An automatic lubricating system is mounted in the base.The heavy tool vehicle class strength tester has the advantages that the principle of relative motion is adopted to simulate the actual operating environment of the tool vehicle; the up-and-down jumpfollowing mechanism stimulates the load, and the load can be up to five tons; the number and shape of the barrier can be arranged freely to simulate reality such as road conditions, and real application can be simulated complet
