Planned Lift: Lift and Rigging Plans Prepared In-House

Planned Lift — lift and rigging plans prepared in-house — concept diagram

PROCON E&C prepares the lift and rigging plan itself: where the crane sets up, how the outriggers bear on crane mats, the working and swing radius, and the gross load (the load plus the rigging) checked against the load chart at that radius. The rigging plan and the pick sequence follow, and the safety plan and the sequence are agreed on with the other trades.

On wide, long roofs some rooftop units sit beyond the crane's reach. The lift method is chosen by comparing reach, weight, crane setups and cost. On one PROCON project the units beyond reach were set by helicopter: the flights were flown by an FAA-certificated external-load operator, and PROCON planned the lift, coordinated the operator and installed the units.

Before each pick: an exclusion zone, a pre-lift meeting, rigging inspection, tag lines, a designated signal person and a wind check. The film follows a motorized skylight set and fastened on a space-frame roof, then a rooftop unit set on its roof curb with the supply and return ducts and unit power connected next.

In this film

  1. 01Lift & rigging planCrane position, outriggers and crane mats (ground bearing) → working and swing radius → load chart check (gross load = load + rigging) → rigging plan and pick sequence
  2. 02Choosing the lift methodRooftop units on wide, long roofs: crane only (more setups and standby) or crane + helicopter, compared by reach, weight, setups and cost
  3. 03Before the pickExclusion zone, pre-lift meeting, rigging inspection, tag lines, designated signal person, wind check
  4. 04Motorized skylightHoist → landing crew guides the unit → set → frame fastened to the curb → rigging released
  5. 05Rooftop units (RTU · MAU)Picked with a spreader bar → set on the roof curb → supply and return ducts, unit power and disconnect → next: equipment hook-up
  6. 06Site footageRTU set by helicopter. Flown by an FAA-certificated external-load operator; PROCON planned, coordinated and installed.

Lift method, crane, rigging and sequence are set per project and site conditions.

Helicopter lifts are flown by an FAA-certificated external-load operator. PROCON plans the lift, coordinates the operator and installs the units.
