TRSCP Vehicle Recovery Techniques 2

Question 1

Which recovery technique involves using the momentum of the recovery vehicle to free a stuck vehicle without a winch?

Accepted Answer

Kinetic energy recovery (snatch recovery)

Answer

Kinetic energy recovery uses a stretchy snatch strap that stores energy as the recovery vehicle accelerates, then releases it to jerk the stuck vehicle free without requiring a winch.

Question 2

When using a recovery strap in a kinetic snatch recovery, the strap should have how much slack before the recovery vehicle begins moving?

Accepted Answer

Approximately 2–3 feet of slack

Answer

About 2–3 feet of slack allows the recovery vehicle to build momentum before the strap becomes taut, which is what creates the kinetic 'snatch' force needed to free the stuck vehicle.

Question 3

A vehicle has overturned on a steep hillside. Which direction should it be uprighted to minimize rollback risk?

Accepted Answer

Uphill, so gravity assists in final placement

Answer

Uprighting a vehicle toward the uphill side positions it against the slope upon landing, reducing the chance of it rolling away or continuing down the hill after being righted.

Question 4

What is the purpose of placing a dampener (blanket or bag) on a winch cable during a recovery pull?

Accepted Answer

To slow the snap-back of a broken cable and prevent injury

Answer

A dampener draped over a tensioned cable absorbs kinetic energy if the cable snaps, reducing the distance and force of the whiplash that could otherwise cause serious injury or death.

Question 5

When recovering a tractor-trailer that has jack-knifed, the operator should prioritize:

Accepted Answer

Separating the units before any recovery begins

Answer

Separating the tractor from the trailer before recovery prevents the articulation joint from transmitting uneven forces and allows each unit to be recovered safely with appropriate equipment.
