Purpose of the line thrower

The line thrower is a new generation line-throwing & rescue appliance fueled by compressed air specifically designed to deploy:

• a line only, or

• an auto-inflating flotation sling & retrieval line, or

• a grappling hook and retrieval line

to an otherwise inaccessible point in both land-based and maritime environments. The line thrower provides an emergency response capability without putting the rescuer at risk.

 

Your line thrower comes completely assembled and ready for operation, except for filling with compressed air.  Adequate training in all aspects of the use of this equipment is essential in order to familiarize yourself with its safe operation and capabilities. Review all instructions in this manual prior to first use.

 

Applications

Some applications of the line thrower include:

• ship to shore line deployment

• swift water rescue                 

• retrieval of mooring lines

• ice rescue                       

• deployment of spill containment booms

• surf rescue                       

• technical high angle/rope rescue

• man overboard rescue/recovery        

• deployment of grappling hooks

• ship to ship line deployment

 

Range

The range of the line thrower varies depending on:

• Type and weight of line used

• Type of projectile and/or accessories used

• Air pressure in projectile at time of deployment

 

This chart provides conservative distances achieved when used by trained personnel in reasonably calm conditions:

 

In an emergency situation additional distances may be achieved by using the equipment at higher pressures. There is a significant safety margin engineered into each unit – permitting safe operation of the units at pressures equal to 120% of rated service pressure on a case-by-case basis.

Safety Features

The launcher Safety Assembly automatically engages each time a projectile is inserted, preventing accidental launch of a projectile. An audible “Click” is heard as the projectile engages, signaling that the projectile is safely engaged with the firing mechanism.

 

A Pressure Relief Assembly is installed in the nozzle of each projectile. Its purpose is to prevent any unsafe pressure build up in a filled projectile, whether in the launcher or not, if exposed to extreme heat such as from a fire.  This Pressure Relief Assembly will rupture if the air pressure goes over a safe limit. The Pressure Relief Assembly is not reusable and must be replaced if it should ever fail.

 

A second Pressure Relief Assembly is installed on the launcher mechanism and is active at all times when the mechanism is pressurized.

 

Multi-Shot Capacity

Our patented Nozzle-Valve Assembly permits any number of projectiles to be pre-charged and stored with each unit, allowing deployment of multiple projectiles in rapid succession.

 

Fueled by Compressed Air

The intended fuel for this system is compressed air-which is non-flammable and non-combustible.

 

CAUTION: The use of any other compressed gas-either flammable and/or combustible, may result in a spontaneous explosion causing severe injuries or death.
