A mobile mechanic in Ankeny called us last quarter wanting to install one of the residential bendpak 4 post lifts in a home shop bay so he could take on more oil-pan-gasket work without contorting under a jack stand. He had been doing mobile calls out of his van for years, and the plan was to transition a growing share of the work into a fixed shop while keeping the mobile side alive for emergency calls. This article is the case study of that install — how we ran the site survey, what we found in the slab, how we sequenced the day, and what the workflow looks like now that the platform is running. If you are considering the same move in the Des Moines metro, the details here map directly to your quote and your install day.
Every quote includes a free site-survey call before the platform ships, so slab and ceiling issues are caught weeks before install day rather than at the truck.
The site survey call before we quoted anything
Before we quoted the platform, we set up a phone site survey. The mechanic sent photos of the bay from four angles, a ceiling-height measurement to the underside of the joists, a slab thickness measurement pulled from the original build blueprint, and a rough sketch of where he wanted the platform positioned. The survey took twenty minutes, and it flagged one issue we would have found on install day anyway: the slab was thick enough for a residential 4-post but he had planned to place the platform across a control joint. Not a deal-breaker, but a small shift in placement saved us drilling anchors into a joint that could open over time.
Site surveys are the single highest-leverage step in specifying bendpak 4 post lifts for a home shop. The number of times a customer thinks the ceiling is tall enough and it turns out to be one inch short is more than we would like. Twenty minutes on the phone, four photos, and a tape measure is enough to catch every common issue before the truck rolls. We do them free with every quote and we strongly recommend the buyer take us up on the offer.
Slab prep and the anchor conversation
The mechanic’s slab was a standard four-inch residential pour at the specified concrete PSI, which is inside the residential-platform spec. bendpak 4 post lifts in the residential tier anchor with wedge-style concrete anchors at each column base, and the anchors need enough embedment and enough edge distance from any slab crack or joint to hold their published load. That is where placement mattered. Moving the platform eighteen inches south of the original plan put every column base clear of the control joint and inside a continuous slab area, which is exactly what the manufacturer wants.
Higher-capacity platforms need thicker slabs, and if a customer wants a 14K or 18K platform in a residential-style bay, the slab conversation gets more involved. Sometimes the fix is a new slab pour; sometimes it is a lift-sized reinforced pad. In this case we did not need any of that — the residential platform matched the residential slab and the anchor pattern was straightforward. Bit selection and drill depth matter, and we bring our own SDS-plus rotary hammers so the customer is not renting equipment. The whole anchor set took about ninety minutes on install day, and every anchor was torqued to spec and documented.
The install-day sequence for a home shop platform
Install day started at eight in the morning with the pallet dropped in the driveway. We unloaded with a forklift the customer already owned — that is a common home-shop scenario and it saves the freight cost of a lift-gate delivery. The columns came up first, in the pre-marked positions, plumbed inside a quarter degree and anchored. Crossmembers followed, then runways lifted into place with a chain hoist off the joists — again, the customer’s own — and the cables threaded through the columns and connected to the powerpack.
By early afternoon the platform was cycling empty. We ran three full empty cycles to confirm no cable snags and even rise across all four corners, then loaded a shop truck for the first loaded cycle. Cable tension was symmetric and the safety locks engaged cleanly. We walked the mechanic through the daily and monthly maintenance steps, handed over the manual and the maintenance binder, and left the driveway before four in the afternoon. A residential platform install for a well-prepared bay is a single working day almost every time. Rushed installs are the ones we do not do — if we cannot finish cleanly by end of day we come back rather than corner-cut.
The oil-pan-gasket workflow that made the platform pay
The mechanic’s core use case was oil pan gasket work — the kind of two-to-four-hour job that eats a mobile technician’s back and knees when it is done in a customer’s driveway. On the new platform, the workflow changed completely. Drive on, raise to comfortable working height, drop onto the safety locks, and stand up under the vehicle with tools staged on the workbench two steps away. What used to be a full day in a customer’s driveway is now a half-day in the home shop, and the customer drops off and picks up on his own schedule.
The economics on that swap are simple. bendpak 4 post lifts in the residential tier pay for themselves quickly on labor efficiency alone if the technician is charging a shop labor rate rather than a mobile rate. The mechanic also picked up work he had been turning down before — jobs that require the vehicle overnight, or jobs that need a follow-up torque check the next day. Neither is practical in a driveway. Both are easy in a home shop with a platform. The lift did not replace the mobile side of the business; it added a fixed-shop side that the mobile side could not serve.
The accessories he added on install day and the ones he waited on
On install day the mechanic added aluminum ramps sized for the platform, a drip tray with the correct dimensions to fit between the runways, and a set of jack-stand-style adapters for when he wants to work at a specific height without cycling the safety locks up or down. He waited on the rolling jacks because his current job mix is heavy on oil pan work and light on suspension. That is a fine trade-off for a technician who is honest about the work he actually books, and we agreed with the sequencing.
The plan is to add rolling jacks in year two if the suspension side of the work grows. Adding jacks later is straightforward — they ship on their own pallet, drop onto the runways, and start earning within an hour. If the mechanic finds himself picking up brake and shock work as the shop side of the business grows, that will be the trigger. In the meantime, the accessories he chose day one are the ones he is using weekly, which is exactly the pattern we want. Do not buy accessories you will not use in the first three months. Buy them when the work shows up.
Ankeny-specific factors we planned around
Ankeny is close enough to Ames that our install crew can drive up in the morning and be back by supper, which keeps install cost predictable. City permitting for a home shop platform is not something homeowners usually need to worry about — the platform is bolted to the slab inside an existing structure, not a permanent structural addition — but if your bay is part of a larger construction project you may want to check with the city separately. In this case, no permits were involved.
Electrical was straightforward: the powerpack runs on standard single-phase 220-volt power that the customer already had for a welder in the same bay. If your bay does not have 220 already, budget for an electrician visit before install day so the platform can cycle on install day rather than sit idle waiting for power. That is another item we catch during the site survey. bendpak 4 post lifts in the residential tier are otherwise plug-and-play once the anchors are set, and the mechanic’s platform has been running without a service call for the past several months.
What we would say to a mobile mechanic considering the same move
If you are a mobile mechanic in Ankeny or anywhere in the Des Moines metro thinking about adding a home shop bay with bendpak 4 post lifts, the honest recommendation is to run the numbers on labor hours saved before you obsess over platform choice. The platform matters, but the biggest lever on payback is workflow efficiency — moving from a customer driveway to a shop bay is a bigger jump than moving between two comparable platforms. Pick a platform sized to your realistic vehicle list, add the accessories you will use in the first ninety days, and save the rest for year two.
We install across the Des Moines metro every week and are happy to run a phone site survey on your bay before you commit to anything. Photos, ceiling height, slab thickness, drive-in clearance, and a rough placement plan is all we need.
