Vertical Elevation Escape Chute (Multiple Exits)

Demo Video



The Multiple Exits Escape Chute is developed from our model: S1 for application on variable altitdue evacuation, such as above ground railway trains, gondolas, amusement parks rides etc. The chute has multiple zippered exits at an interval of 3 meters (approximate 7'). Once reached the safe ground, the escapee just open the closest zipper to exit the chute. The weight of the chute body is about 1.4kg/M (1 lb/ft) and can hold up to 1800 kg (approximate 4000 lbs) at once during evacuation. The Chute is made on spiral form in the left turn direction. The speed of descending is about 2 meters (7') or less persecond. Therefore, no heavy shock or impact should be felt when escapee reaches the bottom of the chute where a pretective landing cushion is attached for additional protection.


As soon as the escape chute is completely installed for use check the state of the hanging chute from another window nearby and start descent in the chute.

The chute is made in spiral form in the left turn direction, so try to descend in it turning the body in the left direction.

The speed of descent is about 2 meters or less per second and the speed never exceeds the above limit.
Therefore, no shock is felt during the descent in the chute or at the time when reaching the protecting cushion in the capsule at the bottom of the chute,

This means that the chute assures the highest degree of safety and no danger at all.

The protecting cushion of the capsule touches the ground, which means the escaping person lands directly on the ground.

Even when many people descend in the chute in succession, there will be no clogging within the chute (in our experiment 34 persons descended smoothly one after the other in 1 minute). Smooth and non?clogging descent is possible. Even if clogging should occur there is no worry at all about the strength of the chute which can withstand a load upto 7,200kg(15,870 lbs).


The weight of the chute is 1.4 kg per 1 meter (15 ounce per 1 foot).


All the parts and components such as the installation bolts anchored on the building floor, installation or fitting metal parts, chute hardware, chute main body and the joints are designed and, made to withstand a sufficient load and do not deform up to the force of 1,000kg (2,200 lbs).
Therefore, the escape chute is strong enough for escaping persons in succession one after the other.


There are some good flame resisting fabrics such as glassfiber cloth, carbon fiber cloth etc. However these fabrics do not have sufficient capacity for wear, abrasion, bending friction and so they are not suitable for our chute cloth.

There are some fabrics which have some flame resisting capacity but their prices are about ten times or so as compared with those of ordinary fabrics, which prevent us from using them for our chute.

We, therefore, use polyester cloth treated to give flame resisting capacity for our outer chute cloth. This cloth is flame resisting, is sufficiently strong and the price is reasonable.


We make our escape chutes using the materials of the highest degree of durability selected out of various materials so that our chutes are excellent in durability, weather resistance etc.

How to Operate

Remove the cabinet cover.
Enter feets first.
Lower chute.
Bend the knees as far as possible and descend with the hip first.
Set up the entrance frame.
Landing on the ground is shock-free.
