Six families of Sumner material lifts cover everything from a 99 lb solo drywall lift to a 1,500 lb dual-winch industrial lift. This chapter is built so you can identify any unit from the floor of a jobsite and jump straight to the matching repair material.
The Series 2000 is the lift most technicians cut their teeth on. Four height variants (2010, 2015, 2020, 2025) share the same base, mast extrusion family, and Sumner-built winch. Capacity drops as height goes up: the short 2010 is the heavy hauler, the tall 2025 is the long-reach unit.
Common service items: winch ratchet pawl spring (intermittent slip), upper-mast cable sheave (cable fraying), lower-mast slide pads (mast bind on extension).
The 2100 is essentially a Series 2000 with everything tightened up: cable runs are routed inside the mast (instead of along the side), the pulley guard is integrated, and the carriage tool-free assembles in seconds. Three height variants (2112, 2118, 2124). Outriggers ship standard with the 2118 and 2124.
Common service items: internal cable abrasion (caused by misrouted cable on the second mast section), reversible-fork pivot pin wear, stabilizer-leg latch.
Designed for one installer to set sheets of drywall, ceiling tile carriers, or small HVAC components overhead without a partner. The whole lift weighs 99 lb and breaks down for transport in a sedan trunk. The defining feature is the 65° tilting head, which lets you load a sheet of drywall flat and roll it into place against the ceiling.
Common service items: tilt-head detent pin (drywall sheet won't lock flat), two-speed winch shifter, cradle padding (replaceable foam).
The 2400 trades reach for footprint — a stowed envelope short enough to lay flat in a service van. The defining feature is 360° cable protection at the head: a ring of formed steel that shields the cable from getting snagged on rafters, conduit, or duct corners during overhead work. Capacity differs by model.
Common service items: 360° guard alignment (off-center after a drop), reversible fork rollers, base axle bushing.
Same mechanical platform as the contractor lifts, but the mast is anodized matte black so it visually disappears against a stage or scrim. AV crews use Eventers to fly line-array speakers, lighting trusses, and projection screens. Three height variants — and as with the Series 2000, capacity drops as height increases.
Service note: the anodized finish scratches easily — use nylon-faced clamps when working on the mast and avoid solvents that strip anodizing.
The Roust-A-Bout is a different animal: twin parallel masts, a shared crossbeam carriage, and two independent winches — one for raising the load, one for extending the mast. That separation lets one operator move a 1,500 lb pipe section vertically and horizontally at the same time. 8″ casters give it the only Sumner platform designed to roll loaded.
Common service items: 4-speed selector linkage, mast-winch synchronization (twin masts can drift if one cable stretches), caster axle bearings, crossbeam carriage rollers.

Doorway clearance: only the R-100 (32″ base) fits through a standard residential doorway. The R-150 and R-250 share a 40″ × 40″ base and require a wider passage.
Use this matrix when you need to spec the right lift for a job, or to confirm a substitute lift can handle a customer's load.
