Construction Technology

Benefit from our experience in manufacturing testing rigs for streets and building constructions.

Mobile Hydraulic Vibration Exciter

Application

This machine is designed to generate vibrations on buildings and frameworks.

Features

A testing cylinder, connected with the swinging mass, generates the necessary amplitude. Due to a special positioning of the swinging mass by an articulated lever system, it is possible to operate the vibration exciter in vertical as well as horizontal position.

  • Adjustable Vibration masses between 100 kg and 400 kg (in steps of 25 kg with replaceable mass plates)
  • Pressure oil supply by hydraulic unit
  • Testing load up to 10 kN
  • Test frequency up to 30 Hz
  • Mobile design
  • Digital control

Street and Floor Testing Rig

Application

The Street and Floor Testing Rig of WPM is designed to simulate static and dynamic loads on floor and road. The strength tests are mainly carried out by pressure loads, but static and dynamic compression and tension loads are possible as well.

Features

  • Control of a synchronous test with up to 4 cylinders with the same or different test loads, as desired
  • Maximum load: 1500 kN

Functioning

A load bridge, specially designed for the testing requirements, is driven over one of the two pits to test the floor or road parts on a rail and is positioned in grid spacing.

At the traverse load bridge, testing cylinders are mounted. The testing cylinders hanging downwards can be laterally moved on the traverse on rollers.

Vertex Pressure Testing Machine

Application

The vertex pressure testing machine SDBP 1000 is especially used for testing reinforced concrete beams and tubes.

Features

  • Test force 1000 kN compression or 500 kN tension
  • Test frame with 4 supporting columns  with a distance of 2800 mm
  • 3-point-bending unit with continuously adjustable support distance  from 600 to 4500 mm
  • With hydraulic drive
  • Measuring and control device EDC100
  • Stand-alone-operation or PC control possible
  • Different user programs for building material and glas, ceramics as well as wood

Testing Rig for Asphalt

Application

The testing rig for asphalt is designed to test bituminous or hydraulically bound building material. The specimens are loaded in direction of pressure as well as other derivable testing methods.

Features

  • Nominal force: 63 kN
  • Frequency: 60 Hz
  • Servo-hydraulic testing unit with temperature chamber
  • Temperature range from -35 to +85°C

Creep Behaviour Testing Machine

Application

The creep behaviour testing machine of WPM serves for static and dynamic creep resistance tests of concrete specimens with special loading and environmental conditions

Features

  • 3-dimensional servohydraulic creep behaviour testing rig
  • Due to high volume of the accumulator, only a short operation of the hydraulic aggregate in long intervals is needed.

Hydraulic Testing Rig for Concrete Components

Application

This testing rig is used to test beam, ceiling and wall elements according to DIN 1356.

Features

  • Length of the elements: 800–6.000 mm
  • Width of the elements: up to 700 mm
  • Thickness of the elements: up to 300 mm
  • Static tests with test force: max. 300 kN
  • 4-point-bending unit to test beams
  • Hydraulic cylinders with stroke 350 mm
  • Hydraulic unit with 280 bar and 15 l/min
  • Controlling with precision control valve
  • Control unit EDC in stand-alone and PC-operation
