Basics
This is the primary function of the TeleCrib Rescue 42 strut during a vehicle extrication.
Vehicle stabilization
Before placing the struts, rescuers must perform this critical safety step to ensure the vehicle will not move unexpectedly
What is chock the wheels and disconnect the battery?
Rescuers must never stand in this zone while tensioning or adjusting the struts.
What is the “collapse zone”?
This is the recommended number of struts for stabilizing a vehicle resting on its roof.
What is four struts (two per side)?
Rescue 42 struts should be cleaned with this type of solution after use.
What is mild soap and water?
The R42 strut is made primarily of this composite material for strength and lightweight handling
Kevlar-reinforced fiberglass
This component is placed at the top of the strut to connect it securely to the vehicle.
What is the clevis head or ratchet strap attachment?
Struts should always be placed at this angle to provide the best stability and strength.
What is approximately 45 degrees?
When stabilizing a vehicle on its side, these anchor points are ideal for the strut tips.
What are the A-, B-, and C-posts or frame rails?
The auto-locking pins should be lubricated with this type of lubricant only.
What is a dry silicone or Teflon lubricant (not oil-based)?
This feature allows the R42 to extend and lock at multiple lengths without tools.
Pin-Free auto-locking collar
When stabilizing a vehicle on its side, rescuers should use a minimum of this many struts for a safe “tripod” stabilization.
What is three struts?
When stabilizing a vehicle, rescuers should always keep clear of this area in case the load shifts or fails.
What is the “danger zone” or “fall zone” of the strut?
To increase lifting capacity, rescuers can do this with the TeleCrib system.
What is pair the strut with a ratchet strap or use it in conjunction with a jack or lifting device?
Struts should be stored in this condition to prevent stress on components.
What is fully retracted?
The "42" in R42 refers to this
The original maximum length (in inches) of the strut
This integrated component on the base of the strut provides traction on a variety of surfaces.
What is the swivel base plate with aggressive teeth?
The safest way to release load from the strut is to do this first.
What is release the tension on the ratchet strap slowly?
This technique uses opposing struts to push against each other and secure a vehicle against lateral movement.
What is “cross-bracing”?
If a fiberglass strut is found to be damaged, this must be done before it is returned to service.
What is take it out of service and notify a supervisor or equipment officer?
This is the maximum load rating of a single strut when used at its shortest length
Approx 18,000 pounds (depending on model)
This type of strap is commonly used in conjunction with the struts to tension and secure the load.
What is a ratchet strap or tensioning strap?
Rescuers should inspect the struts for this condition before and after each use.
What is cracks, delamination, or damage to the fiberglass or locking collar?
During a partial underride with a semi-trailer, these Rescue 42 features make them safer than metal struts near electrical or fuel hazards.
What are their non-conductive and non-sparking properties?
According to Rescue 42 guidelines, any strut that has been exposed to this condition must be immediately removed from service and inspected by the manufacturer.
What is exposure to direct flame, excessive heat, or chemical contamination?
