It might look like an everyday bag, but this revolutionary system could help save lives.
Called SkySaver, the backpack attaches to hooks fitted inside windows and lets users abseil from the top of high-rise buildings in case of emergency.
The bag clips onto the wearer around their chest and between their legs and the harness lowers them to safety.
The hook can be fitted in offices or residential buildings up to a height of 260ft (80 metres) and the system can carry wearers weighing up to 300lbs (133kg).
SkySaver can also be used by children, weighing a minimum of 66lbs (25kg).
After securing the bag to the user’s back using clips that fasten around their chest, the cable is fitted to the hook using a standard climbing carabiner.
They then climb out of the window while facing the building, and the cable automatically begins descending them at a steady speed. Once they reach the floor, they can unhook the cable.
The system was designed by professionals from the Israeli army and rescue and emergency services. It has also been tested by governmental and independent laboratories including Gravitec and Standards Institute Israel (SII)
‘You don’t need assistance or training to use SkySaver – it’s easy and safe,’ explained the firm.
‘SkySaver uses a controlled descent device and an automatic braking system that allows you to descend at a safe speed of up to [6.5ft] two metres a second.
‘We strongly encourage cooperating with all fire and rescue personnel. Your SkySaver should only be used when no other safe exit is available.
‘The SkySaver is designed to be used once and only in emergency situations.’
SkySaver comes in three models.
The SkySaver SKS 80 has a cable length of 80 ft (25 metres) and weighs 18 lbs (8kg).
SkySaver SKS 160 has a cable length of 160 feet (50 metres) and weighs 22 lbs (10kg), and the SkySaver SKS 260 has a cable length of 260 feet (80 metres) and weighs 26 lbs (11.7kg)
