Horizontal Drop Test
- Simulation of very large masses (up to 200 tonnes)
- The machine has a small footprint and requires no civil engineering.
- Short set-up, assembly and disassembly times
- Machine protected by a hydraulic stop; no suspended load thanks to its horizontal position

Sector of activity
Main functions
The horizontal drop shaft (dynamic shock bench) enables linear shocks with adjustable energy, speed and mass. Its revolutionary heavy weights simulation system makes it possible to carry out impact tests corresponding to a collision with a mass of 40 to 200 000 kg at a speed adjustable from 0.5 to 9 m/s thanks to flywheels of a mass of less than 200 kg. A high-frequency acquisition ensures the recording of the force/position curve at 100 kHz and the calculation of the absorbed and restored impact energies.
Operating mode
Using the calculation module, the user selects a weight to be simulated and an impact speed or energy. The software then automatically indicates which flywheel to use. The automatic launcher system accelerates the flywheels to the right speed, the striker is automatically engaged on the flywheels motion. The system is self-protected by a detachable automatically triggered hydraulic stop.
Horizontal drop shaft
The dynamic shock bench enables you to produce linear shocks with adjustable energy, speed and mass.
Location
With a capacity of 50,000 J and a length of 5 m, the machine takes up very little space and requires no civil engineering.
dampers
Dynamic behaviour of viscoelastic dampers for industry.
Crane stop
Simulation of an impact of an overhead crane on its end stops.
Horizontal Chute
For a major manufacturer of shock absorbers, LF Technologies designed a test bench for simulating dynamic shocks of up to 50,000 J, with adjustable mass and speed. Various types of shock absorber (landing gear, silentbloc, etc.) can be tested on this static and dynamic test bench.
Advantages of the Horizontal Drop Well
Shock absorber
Checking the operation of shock absorbers for wagons.
Mass simulator
Simulation of very large masses (up to 200 tons).
Speed
Setup, assembly and disassembly times are kept to a minimum.
Security
Machine protected by a disengageable hydraulic stop. No suspended loads thanks to its horizontal position.
