CAT CLASS: HQ-10650

50-70 ft Telescopic Boom Lift

The 50-70 ft telescopic boom lift—typically called the 60 ft class—is the workhorse of structural steel erection and industrial construction, delivering 13-14 ft of horizontal outreach at full elevation. This class bridges mid-range access and heavy-duty vertical reach, offering substantially greater outreach than smaller units while remaining more maneuverable than the 70-90 ft class. Operating weights range from 2,750 to 14,730 kg across 49 models from manufacturers including JLG, Genie, Niftylift, and XCMG.

Key specifications

Specification	Typical range	What it means
Working height	56–70 ft (17.1–21.3 m)	Platform height plus standard occupant reach; defines the highest work point accessible
Horizontal reach	13–15 ft (4.0–4.6 m)	Maximum outreach from centerline at full elevation; critical for clearing obstacles and reaching over building edges
Platform capacity	200-500 lb (90-227 kg)	Maximum combined weight of personnel, tools, and materials allowed in the basket
Operating weight	12,000-14,000 lb (5,400-6,350 kg)	Machine weight determines ground pressure, transport requirements, and deck loading
Engine power	49-74 hp	Diesel engine output for rough-terrain models; drives hydraulics and propulsion systems

How to choose

The 50-70 ft class is appropriate when work requires both significant vertical reach and horizontal outreach—structural steel connections, bridge girder work, industrial pipe racks, or building façade access where obstacles must be cleared. Choose the Up to 50 ft Telescopic Boom Lift for warehouse and light industrial work under 50 ft, where the smaller footprint and lower operating weight reduce site impact. Step up to the 70-90 ft Telescopic Boom Lift when working heights exceed 65 ft or when horizontal reach beyond 15 ft is required, accepting the larger transport footprint and heavier ground loading that class demands.

What this size handles

Structural steel column and beam connections at 50-65 ft elevations
Highway bridge girder inspection and maintenance with side reach over traffic
Industrial facility pipe rack installation and valve access at elevation
Multi-story building envelope work requiring outreach over lower roofs
Electrical substation bus work and transformer maintenance at height
Warehouse and distribution center high-bay lighting and HVAC service

Safety & operation

Ground conditions and slope must remain within manufacturer gradeability limits, typically 40-50% maximum for this class
Platform capacity ratings vary between restricted (outriggers extended) and unrestricted (stowed) configurations; verify load chart for operating position
Wind speed restrictions apply at elevation; most manufacturers specify maximum operating wind speeds of 28 mph with lower limits for loaded platforms
Fall protection and tie-off requirements vary by jurisdiction; occupants typically must use full-body harness with lanyard attached to designated anchor points

Transport & logistics

Requires tandem-axle equipment trailer rated 14,000-16,000 lb GVWR; most units exceed single-axle capacity
Tow vehicle must provide adequate capacity for combined trailer and machine weight, typically 3/4-ton pickup minimum
Transit dimensions typically 8-9 ft width; verify overhead clearances and road permits for height restrictions

Power & supply

Diesel fuel tank capacity ranges 49-170 liters; plan for 8-12 hour operating duration per tank on typical duty cycles
Dual-fuel (diesel/LP) and bi-energy (diesel-electric) variants available in select models for indoor or emission-sensitive environments
Hydraulic system capacity 68-182 liters; requires daily fluid level inspection and periodic filtration service

Frequently asked

What horizontal reach can be expected at full height?

The 50-70 ft class typically provides 13.2-14.8 ft of horizontal reach at maximum elevation, measured from machine centerline to platform center. Actual outreach varies by boom angle and model; consult manufacturer range charts for specific operating envelopes.

How does operating weight affect site access?

Operating weights of 12,000-14,730 lb require ground bearing capacity of 60-80 psi on typical rough-terrain tire footprints. Verify deck loading for elevated slabs, temporary platforms, and fill areas; outrigger loads concentrate weight further when equipped.

What differentiates unrestricted versus restricted platform capacity?

Unrestricted capacity (272-300 lb typical) applies when the boom operates within a defined envelope close to the chassis. Restricted capacity (454 lb in some models) requires outriggers deployed or boom positioned within tighter angle limits; consult the load chart decal on each machine.
