CAT CLASS: HQ-10651
70-90 ft Telescopic Boom Lift
The 70-90 ft telescopic boom lift class centers on the industry's 80 ft platform, engineered for tilt-up construction, precast panel installation, and commercial roof work requiring substantial horizontal outreach. Working heights span 21.8 to 86 ft across 31 models from Genie, JLG, XCMG, Snorkel, Skyjack, MEC, Elliott, and Niftylift. This size bridges mid-range work where 50-70 ft machines lack reach and projects that don't justify the 90-130 ft class.

Key specifications
| Specification | Typical range | What it means |
|---|---|---|
| Working height | 70–86 ft (21.3–26.2 m) | Vertical reach covering four to six stories and commercial roof decks. |
| Maximum reach | 40–62 ft (12.2–18.9 m) | Horizontal outreach for tilt-up panels and precast placement beyond the chassis footprint. |
| Platform capacity | 500–660 lb (227–299 kg) | Supports two operators with tools and material for panel and facade work. |
| Operating weight | 24,400–48,500 lb (11,068–21,999 kg) | Requires heavy-duty trailers and careful site access planning. |
| Engine power | 48–65 hp | Diesel power for all-terrain mobility and gradeability to 55%. |
How to choose
This size class is the appropriate choice for tilt-up construction requiring outreach beyond 40 ft, precast panel installation on four- to six-story structures, and commercial roof work where vertical reach alone is insufficient. Where projects involve primarily vertical access within 60 ft working height and limited horizontal obstacles, the 50-70 ft Telescopic Boom Lift offers easier transport and lower operating weight. For high-rise facade work, bridge inspection, or industrial applications exceeding 80 ft working height, the 90-130 ft Telescopic Boom Lift provides the necessary elevation and extended reach.
What this size handles
- Tilt-up panel bracing and welding on commercial warehouses and distribution centers
- Precast concrete installation on mid-rise office and institutional buildings
- Commercial roof HVAC equipment placement and service access
- Facade cladding and curtain wall installation on four- to six-story structures
- Industrial building steel erection and overhead utility work
- Sign installation and maintenance on tall commercial buildings
Safety & operation
- Ground conditions and slope must remain within manufacturer gradeability limits; soft or uneven surfaces require outriggers or stabilization
- Wind loading calculations critical at full extension; manufacturers specify maximum wind speeds for operation
- Load charts define platform capacity at various boom angles and extensions; reductions apply at maximum reach
- Proximity to overhead power lines governed by OSHA minimum clearance distances; spotter and lockout protocols required
Transport & logistics
- Operating weights of 24,400–48,500 lb require tandem-axle or tri-axle lowboy trailers rated 20+ tons
- Over-dimensional permits frequently required; escort and route planning necessary for public road transport
- Site delivery demands stable ground conditions and adequate clearance for tractor-trailer maneuvering
Power & supply
- Diesel engines of 36–65 hp with fuel tanks holding 114–170 gallons for multi-day operation
- Tier 4 Final emissions compliance standard across current model lines
- Daily fuel consumption varies with duty cycle; extended reach operations increase engine load
Frequently asked
What horizontal reach distinguishes this class from smaller telescopic booms?
Maximum reach extends 40–62 ft in this class, compared to typically under 45 ft in the 50-70 ft class. This additional outreach is critical for tilt-up panel work and positioning beyond building footprints without repositioning the base.
How does platform capacity change at full extension?
Platform capacity ranges 500–660 lb at stowed position but is reduced at maximum height and reach per manufacturer load charts. Derated capacities at full extension typically support one or two operators with minimal material.
What site access width is required for this size class?
Stowed widths vary by model and tire configuration; all-terrain models are wider than industrial versions. Transport and jobsite pathways must accommodate both the machine width and adequate clearance for stabilizers where equipped.
