Bearing plate test apparatus - DIN

BS 1377:9 | DIN 18134 | PN-S-02205 | BN-64-8931-02
Main features
  • 4 different configurations with 100 and 200 kN capacity, analogue and electronic versions
  • Analogue versions fitted with 200 mm dia. triple scale manometer:  force (kN), oil pressure (Bar) and specific load (MN/m2)
  • Electronic versions fitted with high resolution load cell
  • Dual flow hand pump for quick contact to the reaction frame and for accurate test execution. Flexible hydraulic hose 3 m long included
  • Spherically seated loading jack. The seat surface is magnetic for simplifying the test execution
  • Telescopic measuring bridge made in aluminium alloy, lightweight, transportable and quick to assembly
  • The apparatus can be housed into two easily transportable carrying cases
General description
General description
This Plate Bearing Test determines the Soil bearing capacity by the application of an increasing pressure on a foundation formed by a circular plate loaded against a reaction frame and measuring the associated vertical displacement (settlement).
Results are typically used for calculating the Soil stiffness in term of Deformation Modulus and Subgrade Reaction Modulus.
 
CONTROLS propose many types of Plate Bearing Test Apparatus depending on reference Standards, hydraulic cylinder capacities, plate dimensions, measuring bridges shape, analogue, digital or electronic readings.
This document specifically refers to the DIN models.
Four different DIN models are available:
  • Analogue with 100 and 200 kN capacity
  • Electronic with 100 and 200 kN capacity
Hydraulic assembly
All models use a dual flow hand pump connected to the cylinder with flexible hydraulic hose 3-meter long.
The assembly comprises two spherical seats: the lower transfers the reaction load to the plate; the upper, mounted at the top end of the loading column, is magnetic for simplifying the test execution.
Extension rods are included to close the gap between upper spherical seat and reaction frame.
The entire hydraulic assembly can be housed in a plastic wheeled carrying case available as accessory (35-T1100/HC)

Plate and measuring tunnel
The loading plate is made in high strength structural steel 300 mm diameter. The measuring tunnel, being the reference point for the measuring bridge, is mounted on this plate.
A protection jig is fitted on the steel plate to prevent any buckling of the hydraulic cylinder.
Additional 600 and 762 m dia. plates are available as accessories.

Measuring bridge
Made in aluminium alloy, lightweight, transportable, quick to assembly on site, features 3 adjustable supports and an in-built spirit level. The measuring arm adopts a zero friction - linear bearing solution. The displacement (settlement) measuring device (dial gauge or electronic transducer) is tightly fixed on the arm.
The telescopic arm, with 120 mm stroke, allows precise adjustment of the reference point at the centre of the plate.
The entire measuring bridge assembly can be housed inside a wooden carrying case available as accessory (35-T1100/BC)
 
Load and displacement (settlement) measurement
Two alternatives measuring options are available:
  • Analogue configuration with triple scale manometer 200 mm dia. and 30x0.01 mm dial gauge (other gauges with different stroke and resolution are available as alternative)
  • Electronic configuration with high precision load cell and 50 mm stroke displacement transducer connected to the DATALOG8 readout unit, battery operated.
