Dismantling, transport, storage and post-operational documentation
Planning the dismantle
Dismantling is a high-risk operation - often more dangerous than erection - and needs a documented procedure, a competent person in charge, and the same engineering controls as erection. Sequence matters: land and remove the load and rigging, slacken guys in a controlled order, lower the boom, then remove the mast. Traps: slackening guys in the wrong order, which can drop the mast; and removing anchors before the guys are slack.
Transport
Match transport to the components: mast sections, boom, guys, anchors and winch. Secure loads, check lifting points, and use correct gear. Traps: lifting components by non-designated points; and overloading the transport vehicle.
Storage
Store rope, slings and shackles clean, dry and off the ground; protect rope from UV, heat and chemicals; store structural sections so they do not distort. Tag and quarantine damaged gear.
Documentation
Complete the dismantle record, update the register, record defects found, and file inspection and maintenance records. Traps: leaving documentation until later and losing the evidence.
Worked example
Before slackening any guy, confirm the boom is lowered and the load line is free. Then slacken in the reverse order of tensioning, in small increments, keeping the mast controlled.
Handover
A clear handover record protects the next crew and proves compliance.
