Safety Instructions

The system is rated to the load stated. The end user is responsible for ensuring the loads are securely fastened. Rolatube Technology does not accept liability or provide warranty for usage deviating from the enclosed instructions.

  1. Before deploying the mast please read all warnings below.
  2. Avoid contact with heavy and sharp objects, in storage do not stack anything on top of Rolatubes.
  3. Do not use the mast if there is visible damage.
  4. The end user must assess the suitability of the pegs provided for the intended deployment environment, and replace with more suitable products if necessary.
  5. Rolatube mast systems are rated for wind speeds of up to 100kph (62mph). The maximum wind rating is based on the bare mast correctly deployed and guyed. The end user or system integrator is responsible for ensuring the system is safe with the top load mounted.
Warnings
  1. Ensure the deployment site is clear of any cables or equipment that represents an electric shock hazard.
  2. Do not deploy near power lines, in thunderstorms or winds exceeding 100kph (62mph).
  3. Do not exceed the rated top load of the mast.
  4. Ensure any top load is securely fastened.
  5. Do not allow the mast to bend.
  6. Ensure the deployment site is clear of any underground hazards before using pegs.
  7. Ensure guy ropes and pegs are secure for duration of deployment.
  8. Consideration must be given to the location of any cable from the top load to avoid trip hazards.
  9. Consideration must be given when deploying in proximity to an aircraft landing site for aircraft movement.
  10. Rolatube masts are only designed to function in the vertical axis.
  11. Deploy the mast with the slot facing away from any prevailing wind.
Unguyed Deployment
1

Remove & Unclip

Remove rolled IAM from bag and unclip flying lead from cable clip.

2

Unwind Cable & Unroll

Unwind cable then unroll the IAM.

3

Connect & Lift

Connect the strain relief cable, first to the coaxial connector coming from the IAM, and then to the radio. Lift the IAM to gain height for transmission.

Optional: additional height can be gained by using a line through the rigging hole to haul over a tree branch or other structure.

4

Recovery

For recovery, after detaching radio and strain relief cable, ensure the IAM is rolled from the appropriate end, following guidelines on label.

5

Stow

Wrap flying lead around rolled IAM and clip into place using cable clip.

Guyed Deployment
2 persons required for deployment
1

Position Base Cap

Person 1: Place the flat side of the base cap away from the wind and secure with red base cap pegs.

2

Pace Out Guy Ropes

Person 2: Using the pegs in the base cap for guidance, lay guy ropes’ snaphooks next to IAM. Pace out the 3 guy ropes to 2.5m (8.2′). Insert pegs in ground, attach guy ropes and return to IAM.

3

Unroll & Fit Top Cap

Person 1: Unroll the IAM and place the top cap on the IAM with flat edge aligned to slot, and clip on guy ropes. The trailing lead comes out of the bottom of the IAM.

4

Lift into Base Cap & Secure

Person 1: Lift the IAM into the base cap and support. Person 2: Secure the 3 guy ropes to the pegs and tighten guy ropes sufficiently to maintain stability. Do not overtighten.

5

Connect RF

Connect the strain relief cable, first to the coaxial connector coming from the IAM, and then to the radio.

RECOVERY: Person 2 loosens guy ropes whilst Person 1 lifts IAM from base cap and slowly lowers it to the ground and removes top cap. DO NOT allow the IAM to fall to the ground or damage to top load and IAM may occur. Roll the IAM from the correct end following instructions on the label.
