ZUM WALD – GEZU 450
Tensile testing machine for wooden boards with a cross-section of max. 50 x 260 mm, max. tensile strength 450 kN
Description
Tensile testing machine for checking the quality of boards and solid wood lamellas. Tensile testing machines are used to determine mechanical properties, in particular the tensile strength and robustness of wood lamellas and finger joints. If special safety precautions (optional) are observed, mechanical joints (tensile splices) can also be tested.
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.

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).
