Tunnel construction - Import export

Advantages of the structure marker signs: 1) Impact-resistant, UV resistant and weather-resistant material (ASA) 2) Coloured-through letter and numeral inserts for long-lasting identification marking 3) Patented self-fixing system ensures that numerals and letters remain resistant to shocks and impacts 4) Mounting without screws, thanks to the secure snap-in closures

The company He-ja is specialized in shrink tunnel construction suitable for your product and offers a total of 40 different tunnel variants for dry as well as wet rooms. Our standard hood width is 500-1500mm wide and our standard tunnel lengths are 1,800, 2,200, 2,800 and 3,600mm. Should your product require a special solution, we will certainly find the right technical design for it. The heating power is between 15-36KW depending on the size of the hood and tunnel length. Our bestseller shrink tunnel type T600 with a total length of 1.800mm (hood length 1.200mm) and a hood height up to 300mm shrinks 80my PE shrink films without any problems with a heating power of 15KW at a capacity of up to 10 repackages/min. Thanks to the sophisticated technical design of the control components and the perfect balance between air flow and temperature, you can achieve top values in your energy balance. The actual consumption is reduced by up to 35% in production operations.

Displacement and all mechanical values which can be converted to displacements (e.g. compressive and tensile force, strain, torque and vibration) may be measured by this DC/DC displacement sensor. Typical application areas are the measurement of displacement and strain on machines, servo systems, vehicles, on test plants, in civil engineering and tunnel construction. An integrated maintenance-free electronic and a high-level DC output signal provide an easy handling without any problems. Displacement sensors of series 87240 convert a displacement into an analog electrical signal. They consist of a differential transformer with moveable core, an oscillator and a demodulator. These components are integrated and encapsulated in a cylindrical housing made of stainless steel. The sensors are energized by DC voltage, which is converted to AC by the oscillator and brought to the primary coil of differential transformer.

Angled Plastic Adapters RSAK80 and RSAK130 Unmistakable survey points 3-dimensional monitoring of bridges Roads no longer need to be closed or obstacles crossed as every measuring point can be checked from a distance of up to 200m, range depends on the measurement equipment Simple and quick measurement and monitoring of buildings, façades, supporting structures, pillars, high rack storage facilities, dams and many other objects requiring monitoring For monitoring the formwork during concrete pouring, e.g. for bridge arches, single-faced wall formwork For monitoring railway tracks where there is surrounding building work e.g. bridge and tunnel construction, pressure grouting of railway lines, etc. Measurements and monitoring are possible from virtually any angle and at locations which are difficult to access The RSMP15 adapter with a 12.7 mm mini prism is used for all the applications referred to above if measurements using a prism are desired or necessary Temperature and UV-resistant

Smart Targets RS30 & RS31, self-adhesive Smart Targets RS40 & RS41, self-adhesive For quick positioning using the tachymeter and all common measuring instruments The surveyor’s measuring stick can be attached for measuring subsidence For bridge and tunnel construction For measuring and monitoring façades For industrial construction and hall construction For production lines For ensuring heights and axes are securely marked Temperature and UV-resistant Crosshairs are imprinted on the backing plate under the exact centre of the reflective target to ensure the survey point is durably marked. If the reflective target is damaged at any point, it can easily be replaced and the original survey point can be restored quickly, easily and cheaply. Can be mounted even on difficult surfaces For ensuring heights and axes are securely marked For industrial construction and hall construction For production lines The surveyor’s measuring stick can be attached for measuring subsidence Tempera
