Kässboherer Safety Bitumen Tanker, K STS.F 32 with Remote Control for Discharge is a fine example of industry collaboration, between Hoyer Bitumen-Logistik GmbH and Kässbohrer Fahrzeugwerke GmbH, which improves European best practices for occupational safety and health, as well as discharge operation safety and efficiency in general.

The innovative character of K.STS.F 32 is improving the safety of the driver who is operating the tanker during bitumen discharge. Taking its inspiration from the years of experience of Managing Director of Hoyer Bitumen-Logistik Mr. Carsten Meyer, combined with the innovation culture of Kässbohrer, K.STS.F 32 is the winner of Trailer Innovation 2017 in safety category.

Also the collaboration with the Hoyer Bitumen-Logistik GmbH is the perfect example for Tırsan Solutions vision – becoming the leader in trailer solutions through long-term partnerships.

The problems that Safety Bitumen Tanker with Remote Control for Discharge solve in 5 categories.

PROBLEM 1

Operational Risk: Driver operating within accident prone zone
Main Value added to the Driver: Personal safety, avoiding possible permanent injury, and death prevention

Eurobitume informs that a zone of 6 meters around the back of the tanker where the tanker is connected via a hose to the silo for discharge operation is the most vulnerable zone, and that protective clothing must be worn at all times. According to industry experience this is wheremost of the accidents happen.

Safety Tanker operates with a remote control for discharge. The remote controls signal range is well over 6 meters and can control the electro-pneumatic systems of the tanker from at least 6 meters away.

The driver carrying out the discharge with remote control can stand 6 meters away from the tanker, and hence is out of the immediate danger zone described by Eurobitume and identified by industry best practices.

In case of accident, the driver already standing away from the vulnerable zone where injury due to hot bitumen spill is high, can move away from the accident zone as quickly as possible by pressing the emergency button on the remote control.

PROBLEM 2

Operational Risk: Driver having to climb on the top of the tanker to open the airline valve
Main Value added to the Driver: Personal safety, avoiding possible permanent injury

The top airline valve is situated at the top of the tanker. In old systems, the driver had to climb on to top of the tanker 3.600 m high. In case of an accident, the driver risked falling down and getting injured.

Safety bitumen tanker’s remote control operates all the valves, hence the driver can stand on the ground during operation and the risky and laborious process of climbing becomes redundant.

Furthermore, having to climb on top of the tanker takes a long time and is tedious for the driver. The electronic operations facilitated by the remote control saves time and energy during the discharge operation and increases efficiency.

PROBLEM 3

Accident Risk: Risk for driver and equipment due to unopened air valve related tank vacuum
Main Value added to the Driver: For driver personal safety, avoiding possible permanent injury
For Site Personnel: Health and safety, operational cost reduction
For the Tanker Owner: Protection of equipment, increased total value of ownership

ADR specifications specify that tankers should have 3 valves for safer discharge of the bitumen: First, the top airline valve; then second, the bottom valve (which is the 1st closure unit along the discharge line); and thirdly, the bottom valve (in safety tanker the third valve is a pneumatic butterfly valve) which is the second closure unit along the discharge line. Sequencing of the opening of these valves is important.

The top airline valve should be opened first, to let in air while bitumen is discharged out of the tanker. In case the valve is not opened, a vacuum risk is created, hence increasing even deadly accident risk.

In safety tanker, operations are sequential. In remote controlled operations or panel controlled operations, unless the driver pushes the necessary buttons to automatically open the airline valve, the system does not permit further operations – buttons do not work. Hence vacuum risk due to oversight and possible accidents and equipment damage are prevented.

PROBLEM 4

Emergency Risks: Accidental spilling into the tanker
Main Value added to the Driver: Personal safety, avoiding possible permanent injury
For Site Personnel: Health and safety, operational cost reduction
For the Tanker Owner: Protection of equipment, increased total value of ownership

ADR specifications specify that tankers should have 3 valves for safer discharge of the bitumen: First, the top airline valve; then second, the bottom valve (which is the 1st closure unit along the discharge line); and thirdly, the bottom valve (in safety tanker the third valve is a pneumatic butterfly valve) which is the second closure unit along the discharge line.

In old technologies, in case of an emergency, the 3rd valve, which is the 2nd closure unit, was closed by driver manually operating a lever mechanically attached to the valve. In safety tanker, valves are operated electronically, and pressing the emergency button closes down all the valves including the 2nd valve (the 1st closure unit) as well as 3rd valve (the 2nd closure unit), hence sealing the tank and the liquid in it completely, minimizing the risk of accidental spill into the tank.

PROBLEM 5

Operational Risk: Break problems
Main Value Added to the Driver, Site Operator and Tanker Owner: Accident avoidance

The safety tanker features a smart protection cover over the discharge coupling for the hose connection between the tanker and the silo. Once the smart protection cover is manually opened, Safe Start System locking the breaks of the tanker is activated via a pneumatic key connected to the electronic systems of the tanker.  Hence, once the discharge operation begins, the tanker does not move under any circumstances.
