Q) Which of the following is an important safety rule to remember when using a crank-up tower?
A) This type of tower must never be climbed unless it is in the fully retracted position
NJ2X Notes:
Crank-up masts are typically held in the extended position by a single cable. If this cable were to break then the sections would collapse suddenly. Crank-up towers must never be climbed unless it is in the fully retracted position.
