Software for the yard running curb machines.

A curb machine is the unit a rental yard sends out when a contractor needs to slipform continuous curb, gutter, or sidewalk instead of setting wood forms by hand. It meters concrete through an auger into a shaped mold, vibrates it tight, and lays a clean profile as it tracks down the stringline — work that would otherwise take a forming crew days. That specialization is exactly what makes a curb machine awkward to run as a rental asset: it rarely goes out without the right mold and insert kit, it moves on a lowboy with the crew's grade gear, and it punishes the yard hard if a renter lets concrete cure inside it. EquipFlow runs curb machines the way a working yard does — dispatch, billing, maintenance, and return inspection on one record per unit.

Built inside Rental King, right now.

Rental King is a heavy-equipment rental yard in Odessa and Midland, TX. They run curb machines, manlifts, forklifts, light towers, generators, compressors, and water trucks on MSA contracts through the Permian Basin — 24/7, oilfield pace. EquipFlow was designed and first deployed inside that yard. Every feature was tested against their live operation before it shipped. The product runs there today.

A curb machine is a specialist tool with a narrow renter pool and an expensive failure mode, and that combination is where a yard either makes margin or bleeds it. The money sits in two places. First, standby: a curb job stalls constantly on concrete supply and weather, and if those idle billable days never reach the invoice, the yard eats them. Second, the return: a mold or auger packed with cured concrete is hours of chip-out and sometimes a scrapped mold, and that has to be caught and charged at the gate, not discovered weeks later. The hour meter ties maintenance and billing together, so it has to be captured the same way every return. When dispatch, billing, maintenance, and inspection all read one unit record, the dispatcher quotes right, the mechanic services on real hours, and nobody rebuilds the month from memory.

How EquipFlow handles curb machines on the dispatch board.

A curb machine almost never goes out alone. The mold the customer ordered — barrier, mountable, valley gutter, sidewalk — decides whether the job can run at all, so the dispatch board confirms the mold and the trim-saw or insert kit on the rental record before the truck loads. The machine itself is heavy and tracked, so it rides a lowboy with the curb crew's stringline gear, and the dispatcher schedules the haul, not just the unit. Curb pours are weather-bound and concrete-supply-bound, so start dates slip; the board shows which units are committed to a pour window versus genuinely available, and surfaces a double-book the moment a second job tries to claim the same machine for an overlapping week.

Billing curb machines — MSA, standby, and site-level tax.

Curb work runs on contractor relationships, so the negotiated rate lives as an override on the customer record per machine class rather than in a rate sheet the dispatcher keeps in their head. A rental created for that account carries the right rate automatically, and a separate mold or insert kit rides the same invoice as a line of its own. Standby matters here more than on most gear: a curb machine sits idle and billable through a concrete-supply delay or a rained-out pour day, and the dispatcher marks those standby hours so the invoice shows active and standby separately without a month-end rebuild. Haul charges for the lowboy ride the same invoice. Tax is set on the delivery-site record, so a machine that worked across more than one jurisdiction bills correctly per site, and invoices post to QuickBooks Online on close.

Maintenance on curb machines.

Curb-machine PM runs off the hour meter, not the calendar, because a unit on a steady paving season climbs through a service interval fast while a yard spare sits for months. The hour reading posts when the return inspection records it, and the maintenance module advances the PM clock from that number so the next service lands on real usage. The wear points are specific: the auger and feed system that meters concrete into the mold, the hydraulic vibrators that consolidate the pour, the track drive, and the trim conveyor. PM leans on hydraulic oil and filters, vibrator and auger condition, and track tension alongside the engine service. Work orders, parts, and meter history live on the unit record, which is also where a damage charge from a return inspection turns into a repair ticket.

Curb Machine return inspections.

Two rhythms apply. The operator's pre-shift check is the curb crew's responsibility while the machine is on rent, and on a curb machine it matters because dried concrete left in the mold or auger overnight is its own kind of damage. The yard's control is the return inspection: before the unit comes off rent, the driver runs a mobile-web checklist on a phone — no app install — captures the hour-meter reading, and attaches required photos that cannot be skipped. Curb-specific checks belong here: mold and insert condition and wear, whether the auger and conveyor were washed out or returned packed with cured concrete, vibrator function, track and stringline-sensor condition, and hydraulic weep. The inspection ties to the rental record before the truck leaves, so a dispute over a caked-up mold has photos and a timestamp behind it.

What you give up running curb machines in EquipFlow.

EquipFlow is a web app, so the return inspection needs a signal to load. On a remote highway or rural curb job with no coverage, the driver cannot finish the mobile inspection at the site; most yards run it at the yard on return instead, which means the photos and hour reading land later than ideal. There is no built-in telematics feed today, so engine hours and fault codes from a manufacturer's portal are not pulled automatically — the meter is captured at return. And mold libraries, insert kits, and stringline accessories are tracked as line items against the rental rather than as a separate detailed attachment catalog; a yard with a large, finely-categorized mold inventory should bring that to the demo so it can be scoped honestly.
