CAT CLASS: HQ-10157

Up to 35 ton Rough Terrain Crane

Up to 35 ton rough terrain cranes are the most compact machines in the rough terrain category, designed for maneuverability on congested job sites where larger cranes cannot operate. This entry-level band handles HVAC units, precast concrete panels, structural steel, and light equipment placement on small commercial and industrial projects. For heavier picks or longer reach requirements, the 35-60 ton Rough Terrain Crane class offers greater capacity and boom length.

Spécifications clés

Spécification	Plage typique	Signification
Lifting capacity	11,023–66,139 lb (5–30 t)	Maximum rated load at minimum radius; capacity decreases as boom extends or load moves outward.
Boom length	30–90 ft (9.1–27.4 m)	Telescoping boom provides variable reach; compact models favor shorter bases for tight-site access.
Transport width	7–8 ft (2.1–2.4 m)	Narrow profile permits passage through standard gate openings and confined construction areas.
Operating weight	15,000–50,000 lbs (6,804–22,680 kg)	Lighter machines improve ground pressure compatibility on sensitive surfaces and parking structures.

Comment choisir

This size class is appropriate for small commercial construction sites with limited access, low-rise buildings, and pick weights consistently under 20 tons at typical working radii. The compact footprint and maneuverability justify the capacity trade-off on congested urban sites, tight industrial facilities, and projects where larger cranes cannot position. When lift weights approach the upper end of this band or boom reach exceeds 80 feet regularly, the 35-60 ton Rough Terrain Crane delivers greater stability, longer boom options, and higher chart capacities without requiring all-terrain or crawler mobilization.

Ce que cette taille peut gérer

Rooftop HVAC unit placement on 2–4 story commercial buildings
Precast concrete panel erection for tilt-up warehouse construction
Structural steel setting for small industrial facilities and retail buildings
Equipment placement in confined industrial plants and manufacturing facilities
Glass and façade panel installation on low-rise commercial projects
Utility pole and transformer setting in urban environments with restricted access

Sécurité et opération

Load charts must account for ground conditions; rough terrain cranes rely on outriggers fully extended and properly cribbed on solid, level surfaces
Compact size does not eliminate swing radius hazards; tail swing and counterweight clearance require zone control even on tight sites
Operator certification to NCCCO Mobile Crane Operator standards is required; rough terrain cranes fall under the Telescopic Boom Crane—Swing Cab category
Ground bearing pressure calculations are critical on sensitive surfaces; lighter machines in this band still exert significant point loads through outrigger pads

Transport et logistique

Most models within this band transport on flatbed or stepdeck trailers without requiring special permits for width or weight
Lighter units (under 30,000 lbs) may be towed on heavy-duty tag or gooseneck trailers; heavier machines require lowboy transport
Self-propelled mobility allows cranes to travel short distances between picks on the same site, reducing repositioning time

Alimentation

Diesel engines power both propulsion and crane functions; typical fuel consumption ranges from 2–5 gallons per hour under moderate operation
No external electrical supply required; all hydraulic and control systems operate from onboard engine and batteries
Daily refueling from standard diesel fuel storage on site; smaller tanks (20–40 gallons) require more frequent servicing than larger cranes

Questions fréquentes

What distinguishes rough terrain cranes from all-terrain or truck-mounted cranes in this capacity range?

Rough terrain cranes feature four-wheel drive, large tires, and chassis designed for unpaved surfaces, but are not licensed for highway travel. All-terrain cranes in similar capacities can drive on public roads, while truck-mounted cranes mount to a commercial truck chassis. Rough terrain models prioritize job-site mobility over road transport.

How does lifting capacity change with boom extension and radius on these cranes?

Maximum rated capacity (5–30 tons) applies only at minimum radius with boom retracted. As boom length increases or load radius extends, capacity decreases significantly per the load chart. A crane rated at 30 tons may lift only 5–10 tons at 60-foot radius with boom fully extended.

Can rough terrain cranes in this size class operate on finished surfaces or inside buildings?

Most models in this band can operate on compacted gravel, asphalt, or concrete with adequate thickness to support outrigger loads. Indoor operation is possible if floor loading capacity is verified and overhead clearance accommodates boom and rigging height. Ground protection mats distribute outrigger pressure on sensitive surfaces.
