The German company HDT offers complete, special trucks for several cleaning applications as runway-, taxi-way-, surface-, well- and sewer-cleaning, for garbage collection and pipe-, well- and sewer-inspection-systems. Furthermore HDT is a specialist in designing of high-pressure machines, units or trucks, consultant activities and in developing of new tools for new applications.
Runway Cleaning / Rubber Removal
The innovative Runway-Cleaner, type: “RWC 1000 HS” meets new standards and removes the rubber from runways (“touch-down-zones”) by means of UHP-water (ultra-high-pressure) up to 2.500 bar (36.000 psi) and a parallel working suction device. Because all parameters (working pressure, rotation of nozzle bar, distance between nozzle and surface, working speed and flow volume) can be set individually, all required results can be reached, without harming the runway surface, whether asphalt or concrete.
RWC 1000 HS solves this conundrum using a wheel-mounted, high-pressure cleaning head with a diameter of 1000 millimetres. Located between the vehicle’s first and second axles, the cleaning head uses high-pressure water to remove rubber deposits. The removed rubber and excess water are then completely extracted by suction and stored in the vehicle’s onboard storage tank. The driver is able to constantly monitor the cleaning process from his cab via camera mounted behind the cleaning head.
The RWC 1000 HS features a number of engineering highlights. The heart of the vehicle is a 140 kW Kamat high pressure pump, capable with a flow rate of up to 29 litres/minute at a maximum working pressure of 2500 bar.
The vehicle is equipped with a step less hydraulic transmission for exceptionally smooth performance at operating speeds between 0,5 and 6,5 km/h.
Runway Maintenance Services
For customers who are not interested in investing in a runway-cleaning-unit, HDT, with local partners and representatives, are offering worldwide runway maintenance services, under long-term contracts with airport authorities.
Sweeping and Cleaning Vehicles
HDT, together with partners, offers, beside the runway-cleaner, a range of trucks and cleaning vehicles including:
- Sewer-Cleaning-Trucks
- Combined Sewer-Cleaning-Trucks
- Vacuum Trucks
- High-Pressure-Cleaning Trucks for contractors and/or industry
- Well-Cleaning-Trucks
- Sewer- and Well-Inspection-Systems (Mobile or built-in versions for vans/ trucks)
- Garbage Trucks
- Container Trucks
- Road Sweepers
- Road-Washing Machines
Sewer Clearing Trucks
Our Sewer Clearing Trucks (just high-pressure or combined, high-pressure and vacuum) are built in a modern design. All aggregates (high-pressure-pump, vacuum pump, hydraulic circuits) are all hydraulically driven and powered by two PTO’s (power take off) installed at the truck’s gear.
Tank volumes from 3 to 14 m³ are available as well as “water-recycling-systems”. HDT designed and developed a “winter heating system”, which allows running the trucks with ambient temperatures of up to - 25° C. To heat the water we use the exhaust gases. They are led through a installed heat-exchanger which is installed in the water compartment. A circulating pump pumps the water through the whole installation (filters, pump, hoses, and valves).
Our first delivered trucks (Iasi, Romania) operated till today more then 28.000 hours without any unexpected break (shut-down).
The trucks are designed and built together with a partner company in Austria or with our “joint-venture-company” in Romania.
High-Pressure Water Equipment
HDT designs “tailor made” trucks for their customers and for different industrial applications. High-pressure water pumps from 100 to 550 kW and operating pressure from 100 to 3500 bar, driven by separate diesel engines or by the PTO of the truck’s gear are installed on the truck into temperature- and sound-isolated box-bodies (van-bodies). If requested booster pumps, storage water-tanks (stainless steel), compressors, lockable storage rooms and working benches are implemented into the body.
Well-Cleaning Equipment
HDT developed a combined truck for “Cleaning and Inspecting Water-Wells” for horizontal and vertical applications up to a depth of 300m. The well-cleaning equipment uses high-pressure-water (100 – 300 bar) without any chemicals. Rotating nozzles have been developed which guarantees a sufficient result. During the cleaning process the water with all debris is pumped into the open.
Before and after cleaning the well is inspected with a rotating and swivelling colour-camera, equipped with a zoom. All dates (video picture, comments, pictures,…) can be stored onto a hard-disk or a CD.
This combined truck is unique world-wide. The end-user safes a lot of money, because all necessary equipments are built onto one truck.
Garbage Trucks: Compactor and Rotating Drum
HDT supplies two kinds of garbage trucks: rotating drums and compactors.
The sizes of the garbage compartments can be offered on customer request from 4 to 14 m³. All kind of truck chassis can be used.
Road Sweepers and Road-Washing Machines
HDT supplies professional “Road sweepers” and Road-Washing Machines in nearly all configurations customers may request. The waste compartment can be of following sizes: 3 to 12 m³.
The sweeping width can be offered from 1,8 to 4,2 m. The drives of all aggregates can be done from the truck’s PTO or by separate diesel engines.
Road washing can be an option for all our sweeping machines or can be built separate on a one truck chassis. Surface- or Road-washers can be offered in versions from 100 up to 500 bar and with or without water-recycling.
Runway Cleaning Vehicle
