Koller Engineering
A testing campaign was undertaken on four of Koller Engineering’s most popular restraints using a heavy crash-test dummy.

A specialist in the manufacture of wheelchair accessible vehicle (WAV) products, Koller Engineering has taken the step to ensure many of its restraints exceed ISO 10542 weight occupancy crash-testing standards by 30 per cent.

With safety at the core of its work, Koller states that it continually reviews and updates its range of WTORS (Wheelchair Tie-down and Occupant Restraint Systems).

The firm stated that in order to ensure that it always meet and exceed standard requirements, a testing campaign was undertaken on four of the company’s most popular restraints using a heavier crash-test dummy to reflect today’s passengers.

Each restraint was tested to ISO 10542 which specifies design and performance requirements and associated test methods for WTORS.

Dean Koller, Director of Koller Engineering, explains: “We carried out a test programme following demand from our customers’ who required equipment that exceeded ISO 10542 standards.

“The testing campaign was not just for the wheelchair weight, as our NEXXUS 200 restraint already exceeds this by over 135 per cent, but also for an increased occupant weight.

“The increase in occupant test weight is important as many of our customers are seeing wheelchair occupants exceeding the standard crash test dummy weight of 77.7kg. A Hybrid III 50th percentile dummy which represents an adult male is stipulated in the ISO 10542 standard.

“However, the 50th percentile Hybrid ATD was first introduced in the 1970’s and since then average weights have increased, with a large percentage of the population weighing over 77.7kg.

“We wanted to ensure that our wheelchair occupant restraints and passenger harnesses were the strongest in the world. To make this claim it was important to carry out the increased occupancy weight testing.

“The products chosen for the test programme represent 99 per cent of Koller WTORS purchased and therefore cover almost every scenario.

“As well as being the first WTORS manufacturer to offer a combined wheelchair and occupant restraint tested to wheelchairs up to 200kg, we are also now the first to offer restraints tested to ISO 10542 for occupants up to 102kg making it over 30 per cent stronger.

“This cements our position as the first choice for WTORS when safety and value are the most important consideration.”

Testing was completed on the Koller EXCEL 120 Combined, NEXUSS 200, FAST RS Combined and EXCEL Heavy Duty 4-point plus TITUS passenger harness. All are over 30% stronger than standard ISO 10542 tested wheelchair occupant restraints available on the market.

Established in 1980, Koller manufactures a range of WAV products including wheelchair restraints, floor rails, portable ramps and removable mini-bus type seat fixings.

In October 2021 the firm announced its achievement of being awarded ISO 9001 recertification, a worldwide-recognised quality management standard.

Last year Koller added a compact and portable wheelchair winch called the PortaWinch to its portfolio of products.

It also helped support coach and bus companies earlier this year to meet Public Service Vehicle Accessibility Regulation (PSVAR) requirements with a variety of WAV products to help in the conversion process.
