Tensile testing machine for wooden boards with a cross-section of max. 50 x 260 mm, max. tensile strength 850 kN
Description
Tensile testing machine for checking the quality of boards and solid wood slats. The tensile testing machine can be used to determine mechanical properties, in particular the tensile strength and elongation of wooden slats and finger joints. In compliance with special safety measures (optional), it is also possible to check mechanical connections (pull joints).
Design
The machine consists of the following modules:
Clamping and traction unit, comprising:
- Main support for mechanism
- Base plates for supporting clamping plates
- Clamping plates with special toothing, unhardened, replaceable
- Two guide shafts, hardened and polished
- Two hydraulic hollow cylinders for generating tensile force
- Two hydraulic clamping cylinders for generating clamping force
- Hydraulic fittings for connecting to the hydraulic unit
Clamping unit, comprising:
- Main support for mechanism
- Base plates for supporting clamping plates
- Clamping plates with special toothing, unhardened, replaceable
- Two guide shafts, hardened and polished
2 longitudinal beams for a maximum free clamping length of 1000mm, adjustable from 200mm to 1000mm in 100mm increments.

Measurement
| Position sensor with clamping support on machine for measuring expansion of the wood Path: 0 to 50 mm Accuracy of device: +/-0.02 mm Path measurement is not officially calibrated. | Optional |
| Position sensor with clamping support on wood for measuring expansion of the wood This position sensor must be dismantled prior to rupture. Path: 0 to 50 mm Accuracy of device: +/-0.02 mm Path measurement is not officially calibrated. | Optional |
Safety devices
conforming to SUVA and CE
Machine operation
- The machine is operated from a control panel.
- Clamping pressure freely selectable.
- Tensile force freely selectable.
The test can be carried out to a pre-set tensile force or until rupture. The values are shown on the display. A PC can be connected and data recorded (optional).
