Transporting personnel in comfort and safety at speed across rough terrain in trucks can be difficult.
Especially when they need to be alert and ready for action at the journey’s end. What’s more, in a frontal accident, overhead crash or vehicle rollover, passengers can be seriously injured or worse.
Now, with the Rollover Protection System (ROPS) from VSS, you can provide outstanding safety and protection for personnel in transit. For extra comfort and care the VSS ROPS features the company’s award winning MouleTec® cushioning foam technology. MouleTec improves the blood flow of people who sit for long periods; thereby reducing drowsiness, headaches and pains in the lower limbs.
The VSS ROPS meets the ECE Regulation 66 for rollover accident protection requirement for commercial coaches.
It also meets the Regulation 77 536 covering agricultural vehicle rollover. As well as rollover protection, the frame includes a specially developed tree strike bar to protect occupants from heavy overhead collisions. Each ROPS module is securely locked into place on the truck bed. The high strength galvanised steel frame has been subjected to the most rigorous Finite Element Analysis and then finished product strength assessment tests.
The VSS ROPS modular design allows the seating system to be mounted rapidly on a vehicle with a simple 4-person lift. Design includes gun mounts and stowage of equipment tailored to suit the client’s specification.
The frames can be supplied as 2 or 4 seat modules, combined up to 16 seat installations.

Comfort and Safety
The polycarbonate seats feature MouleTec geometry and principal of passive “unconscious positional control”. Removable easy clean cushions and back squabs can be supplied as required. The ROPS seats can be supplied with scalloped lower back voids which enable soldiers to sit whilst wearing webbing.
As an alternative, the VSS lightweight crew seat can be fitted to replace the standard polycarbonate seat. Vibration tests carried out on the VSS ROPS seating system have demonstrated a 4-fold increase in operation time compared with the daily maximum vibration level dosage allowance. With troops secure and safe in the back of a vehicle customers have seen an increase in average safe driving speeds typically from 50 to 80 kph.
Whether your ROPS requirements are for original equipment or existing vehicle upgrades, VSS engineers can adapt to all makes and models. Contact VSS sales team now to arrange a product trial.
