Prepare The System; Extend The Mast - Will Burt 7-30 HDL Operating Instructions Manual

6.3.1

Prepare the System

To prepare the system for operation:
• Ensure the mast system is stationary on level, stable ground.
• Perform the Pre-Operation Check (Section 6.1)
• Prepare the pneumatic system for operation. As part of this:
• Close the drain cock
• Ensure the air supply is connected to the control box and operational
• Ensure the control box has power (POWER LED will illuminate when power is present)
• If necessary, secure any cables to the mast
• If necessary, secure the payload to the mast (Section 5.13)
• Ensure the proper personnel are available to operate the mast. For applications using guy
lines, a minimum of:
• (2) People are necessary to operate the guy lines (guy lines must be operated opposite
of each other)
• (1) Person must observe the mast to ensure it is standing straight and not leaning in any
direction. For taller masts, binoculars may be required.
• (1) Person must operate the pneumatic system. It may be possible for the person
observing the mast to also operate the pneumatic system.
• Ensure the mast is only being operated in safe wind speeds. Deployment and retraction wind
speeds are payload dependent, however the mast can typically be deployed and retracted in
winds speeds up to 25 mph (40 km/h) assuming:
• 12 inch maximum offset payload from mast centerline
• Masts extended up to 60 feet (18.2 m) can be operated on terrain having a slope up to:
• 5° of vertical for Ultra Heavy Duty masts with payloads of 200 lb. (90.7 kg) or less
• 4° of vertical for Ultra Heavy Duty masts with payloads of 200 lb. to 800 lb. (90.7 kg
to 362.9 kg)
• 2° of vertical for Ultra Heavy Duty masts with payloads of 800 lb. to 1,200 lb. (362.9
kg to 544.3 kg)
• 5° of vertical for Heavy Duty masts
• Ultra Heavy Duty Masts: Masts extended 60 ft. to 80 ft. (18.2 m to 24.4 m) can be
operated on terrain having a slope up to:
• 4° of vertical for payloads 600 lb. (272.2 kg) or less
• 1° of verticals for payloads 600 lb. to 1,200 lb. (272.2 kg to 544.3 kg)
Sail area could impact the mast deployment angle if the wind is blowing in the
direction of the tilt. Consult factory.
• Operating Temperature -20°C to 60°C (-4°F to 140°F)
Check with The Will-Burt Company's engineering team for additional wind information for
customer-specific loading scenarios.
6.3.2

Extend the Mast

This section describes extending the mast. As mast tubes extend, they force water out of the
weep holes. Keep personnel or sensitive equipment away from the weep hole direction while
extending the mast.
