Inside the 12-tonners are advanced technologies for sewer pipe inspection and leak testing with air, as well as the custom-built lifting device with a boom length of 2 meters.
Convenient sewer inspection on the A8
Job
In spring 2012, work began on widening the 22.6 km stretch of the A 8 between Ulm-West and Hohenstadt. Traffic is expected to be moving in six lanes on this section of road by the end of 2018. The run-off water from the road is heavily polluted and previously drained away through the embankment. To protect the groundwater and the soil, the motorway and embankment areas will be sealed off below during the construction work. All surface water will be collected and conducted to a series of eight retention basins where stormwater is treated. As part of this extensive construction work, the pipelines along the road are to be inspected.
Challenge
A job where Martin Eisenring could apply his lifting device to overcome concrete medial strips or steel crash barriers.
Solution
The new acquisition of Kanal Eisenring is a Mercedes-Benz Atego with a 6 m box body and a wheelbase of 4160 mm, which was outfitted according to the wishes of Martin Eisenring. With its total weight of 12 tonnes, it is equipped with a sporty engine: The 6-cylinder in-line engine with 272 HP meets the Euro VI emission standard. The powerful diesel has been in operation since mid-September 2014 and from now on it will be out on the road every day to handle versatile jobs ranging from leak testing of manholes, reaches and joints to the inspection of difficult-to-access reaches and conduits with nominal diameters from DN 100 to DN 1600.
In addition to the technical IBAK system components for sewer inspection and leak testing, the truck was equipped with a lifting device for inspection behind crash barriers on motorways. IBAK implemented the special design in cooperation with a vehicle and coachbuilder. With a boom length of 2 m and a load capacity of up to 150 kg, the load arm is a practical design for lifting the camera and the camera tractor over the crash barriers, which are mostly 75 cm high. The lifting device, made of rectangular steel profiles, can be attached to either the left or right side of the body rear. The distance between the hoist and the vehicle can be flexibly adjusted via a guide rail with a 15 m long and 5 mm thick wire rope.
All solutions are designed for daily work requirements and long-lasting and economical use.
Result
It's Saturday evening, the last of three operating days scheduled for processing the job on the A8. Martin Eisenring is satisfied with the progress of the inspection on the section between Merklingen and Dornstadt, which has not yet been released for traffic. There, he inspected the 4.8 km long pipeline network, which starts with a nominal diameter of DN 300 and ends with DN 800. For this purpose, approximately every 6th manhole was accessed in order to insert the IBAK ARGUS 5 pan, tilt and rotate camera and the camera tractor into the sewer. The powerful drive of the high performance IBAK T 86 camera tractor enables even long distances of pipe to be negotiated. "We were able to utilize the entire cable length of the KW 505. After 500m, the tractor was set down in the manhole and only the cable was retracted. That saved time!" explains Martin Eisenring. Thanks to the ROTAX mechanism, the camera image from the IBAK ARGUS 5 always remains erect and non-reversed, even when the camera head is panned, tilted or rotated, so that the viewer can orient himself without any problems.
While the six-lane expansion of the federal motorway continues, the inspection job has been completed. The truck has already successfully mastered 600 operating hours of sewer inspection. "Since it was collected in mid-September, the vehicle has been in use every day," Martin Eisenring elaborates. For the successful family business, the new acquisition has already proven its worth, so that another vehicle with this equipment is being planned. To optimize work processes, Martin Eisenring will doubtlessly have another new vehicle tuning idea in mind.
Unternehmensvorstellung
The company was founded in 1961 by Stefan Eisenring, the father of the current managing director Martin Eisenring. Since 1992, he has been running the company specializing in pipe and sewer cleaning and inspection under the name Kanal Eisenring in Sontheim an der Brenz on the edge of the Swabian Alb. The basis for the company's work are its high-pressure jetting vehicles, combined suction and cleaning vehicles with water recycling, sewer inspection vehicles and high-performance dry vacuum suction vehicles, all of which are painted eye-catching pink.
Not only has the vehicle fleet grown steadily, but the associated range of services has also been continually expanded.
