Specification Model - 101 Mining Equipment Escape Chute Systems

 

The Model 101 Escape Chute System is designed for large mining equipment p[ant equipment such as dumper trucks and excavators.  The average height from the cabin deck can between 3 to 9 meters dependent on application and vehicle type. In an emergency event the operator would need to evacuate to ground level from the platform to ground level the Model 101 provides the solution.   

 

Escape Chute can be fitted to hydraulic shovel and excavators and provides a rapid means of evacuation in the case of an emergency event. The Escape Chute Storage/Deployment Device for most walkways has been based on the Model 101 design.

 

The deployment storage container will sit in between the hand railing on the operator’s platform side walkway, and is generally located with two or three steps from the operator’s cabin door and back behind the operator’s line of sight where possible.

 

To deploy the chute, lift the red handle and lid and the container will open without any further requirement from the operator.  

 

 

 

 

 

 

 

Chute Specification:

 

Layer 1: The Outside Flameproof Layer is designed to protect the evacuees from flame and radiated heat; this layer can withstand a constant temperature of 650 Deg “C”, and has a melting point of 800 Deg “C”.

 

There is a space between the outer and middle layer, this reduces the radiated heat being transferred to the middle chute.

 

Layer 2: The Middle Layer-Breaking Layer.  This layer has a series of stainless steel coiled springs sewn into the material.  These springs have a small diameter, so as the evacuees travel through the chute they are restricted. The chute is designed to grip but will not hold you.

 

The evacuees place pressure on the chute’s interior wall with their leg’s and arms, the more pressure applied, the more they slow down, less pressure and they will speed up, however in all cases the descent is controlled.

 

Layer 3:  The Inner Layer – Support layer.  This layer is connected to the storage/deployment device, and holds the chute in place; it can withstand the dead weight load of 2 tones. Just sit on the edge, with legs in the chute, and feel it grip you, slide forward and lower yourself to waist level, spread your legs, and slowly lower yourself into the chute.  

 

By applying and releasing pressure against the interior wall of the chute, with arms and legs your descent speed is controlled. The construction of the vertical Escape Chute consists of inserting three separate fabric tubes one inside the other.

 

Ø The Inner Chute supports the weight of the chute users.

 

Ø The middle chute consists of a nylon material into which we have sewn coiled stainless steel springs,  these springs restrict the travel of the chute user, but not enough to totally support the user, this is achieved by the user placing pressure against the Inner Chute wall.

 

Ø The Outer Chute is provided as heat resistant and protects the chute and evacuees from flame or radiated heat.
