A workhorse boom-truck crane built for extended-duration lifts. 38 tons of capacity, a 127-foot main boom, and Altec’s LMAP safety system — operated by an NCCCO-certified pro on every job.
The Altec AC38-127S is a telescopic boom-truck crane purpose-built for jobs that demand extended operating time and precision. The operator sits in a rotating, climate-controlled cab — not exposed on a deck — which means steady control on long-duration lifts and zero comfort fatigue affecting the work.
At the heart of the crane is Altec’s LMAP (Load Moment & Area Protection) system. Before a lift starts, our operator programs the working envelope — angle, length, rotational limits — and the crane sounds an audible alarm before any boundary is crossed. Combined with a rated-capacity limiter and an anti-two-block device, this crane brings serious safety hardware to every job.
Five-section main boom. 137 feet of sheave height standard. A 15,000-lb two-speed piston winch with rotation-resistant wire rope. This is a crane built for the variety of work the DC metro throws at us — and built to handle it safely.
With a maximum lifting capacity of 76,000 lb (38 tons / 34,473 kg), the AC38-127S handles HVAC drops, structural steel, transformers, and other heavy commercial loads with comfortable margin.
A 127-foot 5-section telescopic main boom delivers 137 feet of maximum sheave height. With the optional two-stage jib deployed, that reach extends to 192 feet — enough to clear tall buildings, mature tree canopies, and complex multi-story installations.
Rotating crane controls and a comfortable operator seat keep the operator focused on the load — not on fatigue. Add the LMAP system’s real-time boom-length, angle, load-on-hook, and capacity-percentage display, and you get a crane built for precision in tight spots.
Every feature below ships standard on the AC38-127S. Combined with our NCCCO-certified operator, they make this crane one of the safest boom trucks on the road.
Altec’s integrated safety system. Before the lift begins, the operator defines the working envelope — boom angle limits, boom length limits, and rotational position limits. The system sounds an audible alarm before any limit is crossed, preventing overload and unintended boom paths.
Continuous monitoring of load weight relative to crane capacity. The system displays boom length, boom angle, load on hook, and percent of rated capacity in real time.
Prevents the hook block from contacting the boom tip — a critical safeguard against cable failure and load drops.
The crane cannot be operated until outriggers are properly deployed. Eliminates the most common cause of boom-truck tipping incidents.
We use this crane on a wide range of lifts across the DC metro. A few jobs where its capacity, reach, and precision really pay off:
Rooftop unit drops on 3-, 4-, and 5-story buildings. The 137-foot sheave height clears most commercial structures with room to spare, and the LMAP-managed envelope makes tight setbacks safe and predictable.
Channel letters, monument signs, billboards, and municipal signage at height. The rotating cab and precise controls make multi-piece sign assembly straightforward.
Tight residential lots, mature trees, and structures-too-close removals. With the jib deployed, the AC38-127S can reach over and through canopies that knuckle-boom and smaller cranes can’t safely handle.
Structural steel placement, precast concrete sets, curtain-wall installs, and material staging for general contractors.
Grand pianos, safes, hot tubs, large furniture, and oversized items moved through windows, over rooflines, and into otherwise inaccessible spots.
Pole setting, transformer placement, antenna installation, and other utility lifts.
