MEC 4046SE Scissor Lift: Specs, Price and Buying Guide

Last updated: October 2026

The MEC 4046SE is a 47 in wide electric slab scissor lift with a 38 ft 8 in platform height (about 45 ft working height) and a 750 lb capacity on current models. Its large deck and 35 in roll-out extension make it a common choice for ceiling, lighting, sprinkler and HVAC work in warehouses, big-box stores and other tall buildings with smooth floors.

This guide covers the 4046SE’s specs and features, how the model changed over the years, how it compares to similar 40 ft slab lifts, what it costs used, and what to check before you buy one.

Specs are from MEC’s current 4046SEac spec sheet and SE-series operator’s manual (ANSI A92.20). MEC’s product page lists a 30 ft outdoor platform height, but the spec sheet and manual say 28 ft. Early units differ (see below), so check the serial plate and decals on the lift you’re buying.

• Early DC 4046SE (about 2017 to 2019): part of MEC’s DC slab line launched in 2017, with direct electric drive and a 550 lb capacity. It weighs about 6,770 lb.
• 4046SEac (current): AC electric drive, 750 lb capacity and 7,140 lb weight. Listings don’t always say which version a unit is.
• 4046+ (2026): MEC’s new PLUS version with AC motors that recapture energy, 900 lb capacity, a 36 in extension rated for 300 lb, 3.2 mph drive speed and 30% gradeability. It is about 46 in wide and weighs about 7,450 lb. Few have reached the used market yet.

Because capacity changed from 550 to 750 lb, always confirm the rating on the serial plate rather than relying on a listing or brochure.

• Large work platform: an 89.5 x 44 in deck that grows to 124.5 in long with the 35 in roll-out extension, which has several locking positions.
• AC electric drive: current models use AC drive motors with fully proportional drive and lift controls for smooth positioning near ceilings.
• Fold-down guardrails: folding the rails drops the stowed height from 102 in to 79 in, so the lift fits through lower doorways.
• Maintenance-free AGM batteries: sealed batteries need no watering, and the automatic charger works on 110 to 230V power.
• Easy service: a slide-out tray for electrical and hydraulic components, numbered wiring, lube-free scissor bearings and onboard diagnostics.
• Safety systems: active pothole protection, a multi-axis tilt sensor, descent and all-motion alarms, a drive speed interlock, emergency stops at both control stations, multiple disc brakes and a scissor maintenance lock.
• Leak Containment System: MEC’s patented system helps keep hydraulic fluid off finished floors.

Options include an inverter for power tools, a tool tray, a pipe rack, a sheet material tray, a cold-weather package and MEC’s Proactive Platform Safety System.

The 4046SE competes with other 40 ft, 47 in wide slab scissor lifts. MEC’s current model carries more weight than the Genie GS-4047 and uses AC electric drive instead of hydraulic drive.

The JLG 4045R, now replaced by JLG’s ES4046, is another common used option in this class. If you need more height, MEC’s 4555SE reaches a 45 ft platform height at 55 in wide. For a lower, lighter option, the 3346SE reaches 33 ft at the same 47 in width. Compare the full lineup in our MEC scissor lift guide or read our Skyjack SJ4740 guide.

• 750 lb capacity on current models, more than most 40 ft slab lifts
• Large deck with a 35 in roll-out extension
• AC electric drive and sealed AGM batteries keep maintenance low
• Fold-down rails lower it to 79 in for doorways
• Still in MEC’s current lineup, so parts are easy to get

• Outdoors it is limited to one person and a 28 ft platform height
• At 7,140 lb with 2,250 lb wheel loads, it needs floors and elevators rated for the weight
• Early DC units carry only 550 lb
• Slow lift time (about 84 seconds to full height)
• Fewer used units for sale than the Genie GS-4047 or Skyjack SJ4740

The 4046SE is built for indoor work on smooth, level floors at heights a 26 or 32 ft lift can’t reach, including:

• Lighting, electrical and low-voltage cabling in warehouses and distribution centers
• HVAC, sprinkler and plumbing installation and repair
• Ceiling, insulation and painting work in tall buildings
• Racking, signage and fixture installs in big-box stores
• Stage, lighting and event setup in arenas and convention centers

Outdoors, it can work on firm, level pavement within its 28 ft outdoor limit and 28 mph wind rating. For rough ground, use a rough terrain scissor lift instead.

In October 2026, FleetNow had 8 used MEC 4046SE listings, all 2020 to 2023 models with about 150 to 330 hours, asking $17,400 to $22,900. Newer 2024 units listed elsewhere at about $32,000.

Similar lifts listed on FleetNow at the same time:

• Genie GS-4047: about $8,000 to $17,200, with most near $12,000
• Skyjack SJ4740: about $10,500 to $36,900, with most near $15,500
• JLG 4045R: about $11,900 to $20,400 (5 listings)

Low-hour, late-model 4046SE lifts cost more than older Genie and Skyjack units, but they carry more weight. Prices change daily, so see current listings for the MEC 4046SE.

• Serial plate and decals: confirm the year, whether it is a DC or AC model, and the capacity (550 or 750 lb) and outdoor ratings.
• Inspection records: ask for the last annual inspection and any repair history.
• Batteries and charger: check the age of all four batteries and the charger, and run the lift through a full charge cycle. Replacing the battery set can cost $1,000 or more.
• Fault codes: check the controller display for stored codes. LL means the lift is out of level, and code 18 means a pothole guard did not deploy.
• Pothole guards: raise the platform and make sure both guards deploy fully.
• Safety systems: test the tilt alarm, emergency stops, emergency lowering knob, descent alarm and brakes.
• Scissor stack: look for bent arms, cracked welds and worn pins, and watch for sway at full height.
• Hydraulics: check the lift cylinder and hoses for leaks, and make sure the platform holds height without drifting down.
• Deck, rails and gate: the extension should slide and lock, the guardrails should fold and pin securely, and the gate should close on its own.
• Tires: look for chunked or flat-spotted non-marking tires.
