Open Skip Containers
Open skip containers (Absetzcontainer) to DIN 30720 / SS 3021. Volume 3.5 – 12 m³. Asymmetric, symmetric and special designs from structural steel S235JR+N / S355JR+N.
Description and Use
Open skip containers are built for the most demanding service in construction, waste management, recycling and secondary raw material collection. Structurally they rank among the most robust container types.
We manufacture them in two construction variants: heavy design with rolled UNP profiles (floor 6–8 mm, side walls 4–6 mm) and lightweight design with bent U-profiles (floor 4–6 mm, side walls 3–4 mm).
Material: structural steel S235JR+N and S355JR+N.
Design variants
NM Asymmetric skip
The most universal solution for waste collection. The combination of a low loading edge on one side (max. 1 200 mm) and a higher opposite side provides a good compromise between manual loading and transport volume. The pivoting hook for emptying is on the side of the low end.
Two construction variants:
— Lightweight version — frame from bent U-profiles. Suitable for lighter waste and less intensive use.
— Heavy version — frame from rolled UNP profiles. For construction waste, rubble and aggressive environments.
The loading edge of the low end is reinforced with a double rolled profile. This part of the container is the most exposed — in practice it is precisely the top edge of the low side that suffers mechanical damage during loading. The double reinforcement significantly extends the container lifespan.
Best for: Collection yards and operations where the container is loaded alternately by hand and by machine.
- Low edge — manual loading of heavy loads up to 1 200 mm
- Universal use — manual and mechanised loading
- Two construction variants per use intensity
- Reduced volume compared to symmetric variants
- Pivoting hook only on one side — correct orientation required during loading

NMS Symmetric skip with bevelled ends
Both sides have equal height with lowered ends. Pivoting hooks on both sides allow emptying from any side without rotating the container.
Best for: Operations with frequent manual loading and flexible logistics where bidirectional access matters.
- Pivoting hooks on both sides — no orientation issues
- Lowered ends — comfortable manual loading from both sides
- Even load distribution
- Reduced transport volume due to bidirectionally bevelled ends

NMSV Symmetric V-skip with even top edge
Symmetric construction and even top edge enable full utilisation of transport volume. Pivoting hooks on both sides allow bidirectional emptying.
Best for: Operations with predominantly mechanised loading where volume matters more than loading edge height. From 10 m³ upwards we recommend exclusively machine loading.
- Maximum transport volume of all open types
- Pivoting hooks on both sides
- With increasing volume the height grows — worse manual loading
- Over 10 m³ only machine loading

Special designs
SM Sludge Skip (Schlammmulde)
Watertight skip for transport of sludge, liquids and sediments. Asymmetric design with watertight welds. Inside are 4 longitudinal and 3 transverse L-profiles — forming a grid that serves as a baffle during transport. The entire construction is reinforced for extreme load. For high-corrosion environments we recommend increased plate thickness.

NMSV-K Crane skip
Based on NMSV construction, reinforced for dynamic load during crane handling. Forged lifting eyes with 7-ton capacity per eye. Symmetric design is necessary for even weight distribution during lifting.
Two construction variants:
— Light version — side walls 4 mm, floor 6 mm. Capacity up to 10 000 kg. Suitable for lighter waste and smaller crane loads.
— Heavy version — side walls 6 mm, floor 8 mm. Capacity up to 12 000 kg. For construction waste, rubble and extreme loads.
Best for: Transhipment, dumps, rail terminals and construction sites where containers are moved by crane.
- Integrated crane attachments — safe crane handling
- Forged lifting eyes with 7 t/eye capacity
- Two variants per required capacity (10 t / 12 t)
- Symmetric construction — even load distribution during lifting
- Only 5 and 7 m³ — limited volume range
- Higher weight due to reinforced construction

KM Skip with hinged doors
Skip type common in the Vienna region. The hinged doors allow entry into the container with a wheelbarrow or lighter mechanism. The low height allows manual loading from all sides. Around the perimeter, exclusively rolled profile is used for increased impact resistance. The doors are deliberately lowered — they must be robust enough for daily use but at the same time light enough so the operator can safely close them without assistance.
Door construction: 4 strong hinges with grease nipples, galvanised hooks, reinforced frame. Side closing ensures reliable securing during transport.
