BendPak 4 Post Lifts: Ames Fleet Garage Build-Out Sequencing

When the Ames municipal fleet asked about adding bendpak 4 post lifts to their existing service building, the question was not just which lift to buy, it was how to sequence the entire garage build-out so the new bays came online without disrupting the eight bays already running. The fleet techs were doing CV axle and half-shaft work daily on the police cruiser fleet, and every day of bay downtime meant a cruiser stayed off the road. Below is the safety-first build-out walkthrough we used, which covers slab, electrical, ventilation, and lift install in a sequence that keeps the rest of the shop operational. The core lesson is that timing matters as much as specification.

Sequence the Slab Work Before the Lift Ships

The single most common Iowa build-out mistake we see is ordering the lift before the slab is ready. Freight lead times on bendpak 4 post lifts run around three to four weeks from order to arrival, and a slab pour with proper cure time takes at least four weeks before it is ready to accept anchor bolts. If those two timelines overlap wrong, the lift arrives and sits crated in the corner of the shop while the concrete cures, taking up floor space and blocking other work that the fleet needs to keep doing.

For the Ames municipal fleet build-out, we backed into the sequence from the target service date. Slab pour first, cure for twenty-eight days with periodic wetting for strength, then permit inspection, then the lift order goes in. That way the concrete is ready and inspected the same week the crate arrives, and install day is genuinely install day rather than a wait. The fleet manager did a two-page schedule with all the trades and shared it with everyone, which is unusual for a municipal project but which shortened the total build-out by three weeks compared to the previous bay expansion. Small coordination beats big scrambling every time, and the slab is where the whole project succeeds or fails at the very beginning.

Electrical Rough-In While the Slab Cures

The twenty-eight-day slab cure is not idle time. That is when the electrical rough-in happens: home-run from the panel to the future lift location, conduit run through wall or across ceiling, dedicated disconnect installed within sight of the future lift position. On bendpak 4 post lifts we install for Ames municipal, we mark the exact powerhead location on the slab before the electrical work starts so the electrician can trim conduit stub-up to within a couple of inches of the final position.

Doing the rough-in during the cure means the electrician is not showing up on install day and stepping around a partially assembled lift. It also means the circuit is inspected and signed off before the lift arrives, so when the crate comes off the truck the only remaining work is mechanical assembly and hydraulic bleed. Municipal permit inspectors appreciate the sequence because it lets them inspect the electrical work in isolation rather than at the same time as everything else. The Ames build-out we did had electrical inspection at day 21 of the cure period, mechanical install at day 30, and combined commissioning at day 32. Every one of those steps had a clean handoff, and no trade had to wait on another.

Ventilation and Lighting Above the New Bay

Ventilation and lighting are the two above-slab items that often get missed in a lift bay build-out. Ventilation matters because CV axle work involves grease and lubricants that offgas, and any bay handling engine work or brake service needs adequate air exchange. Bay lighting matters because a four-post lift blocks overhead lighting when raised, and a bay lit only from above the collapsed-lift position leaves the tech in shadow at working height. Both are cheap to add during construction and expensive to retrofit later.

For the Ames build-out, we specified LED strip fixtures at bay walls rather than overhead, which put the light source at the same elevation as the raised lift and eliminated the shadow problem. Ventilation was tied into the existing shop exhaust system with a new duct run and a dedicated fan, sized to give the bay eight air changes per hour when the lift is in use. On bendpak 4 post lifts installed for municipal fleet service, we recommend the fleet manager include these details in the base bid rather than as change orders, because retrofitting lighting and ventilation after the lift is installed is significantly more expensive. The fleet manager we worked with folded both into the general contractor’s scope.

Delivery and Staging for Bendpak 4 Post Lifts

Delivery day for a lift is a scheduled event with real logistics. The crate ships on a 53-foot dry van and needs a level, cleared area near the future install spot for staging. For an Ames municipal shop the ideal is to have the crate come off the truck at the roll-up door adjacent to the target bay, get moved with a forklift to the bay, and unpacked inside where the assembly work will happen. Bendpak 4 post lifts arrive on a single pallet with the columns strapped upright and the runways banded, not the kind of thing you hand-carry in.

We coordinate the delivery window with the fleet manager and the freight carrier and typically ask for a four-hour window that fits into the shop’s daily flow. Municipal shops usually have their own forklift or can borrow one from public works, so unloading is not a problem, but we confirm equipment availability the day before. On the day itself, one of our techs is on-site to inspect the crate before the driver leaves, sign the bill of lading, and coordinate the move to the install position. The whole delivery-and-stage sequence typically runs ninety minutes. Everything after that is mechanical assembly, which we schedule for the following day.

Install Day: What Actually Happens on Site

Install day for a four-post lift is a two-technician, six-to-eight-hour job under normal conditions. The sequence is: unpack and inventory all parts, set the four columns in their marked positions, run cables through the top sheaves, connect runways to carriages, install the powerhead and hydraulic lines, bleed the hydraulic system, run the lift through its full range of motion with no load, then run it again with a test vehicle to verify lock engagement at every position.

On bendpak 4 post lifts we install for Ames municipal, our two-tech team runs this sequence from arrival at 7 a.m. to sign-off around 3 p.m. on a typical day. The variables are slab flatness, which can add shimming time, and electrical connection, which is quick if the rough-in was done right and slow if wire runs need to be relocated. We photograph every step for the fleet manager’s records and hand over a printed commissioning report at the end. The fleet manager signs it, we upload a copy to our records, and the ALI-certified inspection tag goes on the lift. The bay is operational the same day, though we recommend the fleet techs run five or six no-load cycles the following morning before putting a real vehicle on it.

Commissioning and First-Lift Safety Check for CV Axle Work

Commissioning is more than just verifying the lift raises and lowers. For CV axle work specifically, the fleet techs need to know the exact lift height for a comfortable working posture, the specific lock position that gives that height, and the standard procedure for engaging the pawls before crawling under. Our commissioning walkthrough includes a demonstration with a fleet vehicle: park a cruiser on the lift, raise to the working height, engage the locks, verify all four pawls are seated, and walk the tech through the axle removal sequence step by step.

That first-lift walkthrough is where the safety culture is set. If the first tech to use the lift skips the lock engagement or fails to verify pawl seating, that becomes the shop culture. We take an extra hour on commissioning day to walk each of the fleet’s techs through the sequence one at a time. It is an investment that pays off across the equipment’s lifetime. On bendpak 4 post lifts we install for municipal customers, we also leave a written procedure card at the powerhead with the safety-check sequence in three bullet points. The card is laminated and hung from a hook on the column, so any tech using the lift has the procedure in their sightline. Simple, boring, effective. See our installation guide.

Handing Over the Bay to the Fleet Techs

The final step of the build-out is the formal handover. We schedule a meeting with the fleet manager and any lead techs at the end of install day, walk through the commissioning report, demonstrate the operation and safety sequence, and answer questions. The bay is signed over to the fleet’s operational control, and any future service requests come through our normal channels rather than through the install contact.

For the Ames municipal fleet, the handover meeting was thirty minutes and covered the operational sequence, the safety card, the location of the disconnect, the location of the fluid fill point, and the annual inspection schedule. We left the fleet manager with a folder that included the commissioning report, the ALI certification documentation, the warranty registration, and our service contact card. On bendpak 4 post lifts we install for municipal customers, we schedule the first annual inspection twelve months out at handover so it does not get lost in the fleet’s calendar. The bay went live the next Monday and processed six CV axle jobs the first week. The rest of the shop kept running through the whole build-out without a single day of disruption.
