Feasibility envelopes for mast climbing work platforms and cited rental bands for two-point suspended swing stages. Mast climber rental has no published rate, so it is marked quote-locally.
This is the exact table the Aerial Lift Cost Calculator runs on. Cite it as: Antero Trail, "Mast climber and suspended swing stage envelopes and rates", anterotrail.com/tools/reference/specialty-access-methods. Primary sources are listed with each value and at the bottom of the page.
Specialty-access method reference for the C3 lift scenario (PRP-CALC-3). Two priceable methods. (1) mcwp_envelope: mast-climbing work platform HEIGHT/CAPACITY feasibility envelopes from manufacturer spec pages - NO public rental $ rate exists for MCWP (quote-only), so these confirm the method fits and the rental line is quote-locally. (2) suspended_scaffold_rates: cited rental bands for two-point swing stages / suspended scaffold (OSHA 1926.452(p)). (3) selection: stated-default routing thresholds. Standards (OSHA 1926.451/452, ANSI/SAIA A92.9) constrain DESIGN and appear in the narrative; they are not dollar sources.
Height/capacity from manufacturer spec pages. Used only to confirm feasibility and pick mast count - mast climbers rent by project quote, not a published rate.

| Hydro Mobile P-Series | 15-100 | 250 | Up to 250 ft (76 m) without prior authorization from Hydro Mobile; higher needs manufacturer engineering. | 6,000 | 7,500 lb at 7'5" platform / 6,000 lb at 27'5" (max single-mast platform length). | 9,750 | 11,450 lb at 63'4" / 9,750 lb at 83'4" (max twin-mast platform length). | 27.4 | 83.3 | 7 | not published | not published | not published | HYDRO MOBILE |
| Hydro Mobile M-Series | 20-250 | 250 | Up to 250 ft (76.2 m) nominal per unit; two units linked reach up to 148 ft with load distributed across platforms. | 22,000 | not published | not published | not published | 64 | not published | 3 | M-Series 24' unit: 22,000 lb at 24' platform / 16,600 lb at 64' platform. M-Series 14' unit: 22,000 lb at 14' / 19,300 lb at 34'. Heavy-masonry class; climb 3 ft/min.

| Fraco ACT-8 | not published | 550 | Up to 168 m (~550 ft) on a ground base with anchors; 13.7 m (~45 ft) on a freestanding (un-tied) base. | 8,000 | not published | not published | not published | 58.5 | not published | not published | 3,630 kg (~8,000 lb) per mast, single-mast configuration. | 45 | 118.7 | FRACO |
Professional rigging setup (erect). Parapet-wall rigging modifications add $500-$1,500 where the roof has no ready anchorage.
The per-system monthly/weekly bands and the install/delivery figures come from ONE rental-company published rate guide (EZ Access & Equipment). The overall monthly range ($1,600-$2,000+) is corroborated by a second source (Scaffolding Solutions). Per-system bands are single-source - surfaced on output; confirm the local quote.
| system ID | label | monthly low | monthly high | weekly low | weekly high | fits run FT max | note |
|---|---|---|---|---|---|---|---|
| single_line_basket | Single-line basket / work cage | 1,400 | 1,800 | 400 | 600 | 8 | Short single-worker cage; one location / short drop. |
| double_line | Two-point swing stage (standard) | 1,600 | 2,200 | 500 | 750 | 40 | Standard two-point adjustable suspension scaffold - the default swing stage. |
| multi_motor | Multi-motor / long platform | 2,000 | 3,500 | 750 | 1,000 | not published | Longer platforms, multiple hoists - long facade runs. |
| two_tier | 2-tier stage system | 2,500 | 4,000 | 900 | 1,200 | not published | Two stacked platforms; not auto-selected - offered as an alternate. |
masonry_facade -> MCWP; light_facade + roof rigging -> swing stage; light_facade + no roof rigging -> MCWP. Swing-stage system by facade_run vs fits_run_ft_max (default double_line when run unknown). MCWP mast_count = 1 if run <= single_mast_platform_ft else 2; run > twin_mast_platform_ft flags added masts/relocations.
Industry guidance suggests MCWP runs 30-50% cheaper than equivalent scaffolding on mid/high-rise facades (Alborz Ghaleb, qualitative - https://www.alborz-ghaleb.com/mast-climbers/, accessed 2026-07-12). ESTIMATING HEURISTIC / single-source: use only as a soft alternate note, never as a dollar figure.
