Software for the yard running rammers.

A Rammer hydraulic breaker is the attachment a rental yard hangs on an excavator when a bucket has met something it cannot dig — reinforced concrete, caliche, boulders, frozen ground. It is not a machine that runs on its own; it borrows the carrier's hydraulics, and that dependence is the whole story of renting one. Get the flow, pressure, and weight class matched to the customer's excavator and it breaks all day. Get it wrong and the hammer either hits soft or blows its seals on the first shift. Add an operator who fires it in open air or lets the grease run out, and a breaker comes back needing a rebuild. EquipFlow handles Rammers the way the yard that built it handles them — carrier matching on dispatch, billing, hour-meter 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 rammers, 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 breaker is a low-headline, high-rebuild unit, and that is exactly where a yard bleeds money on attachments. The damage that matters is invisible from across the yard: a stretched tie rod from blank-firing, a bushing scored from running dry, a valve fouled by dirty oil. None of it shows unless someone inspects for it before the hammer goes back out. Run hours are the spine of both maintenance and billing, and since most breakers carry no meter of their own, the run time has to be captured the same way every time — at return, against the rental record. When dispatch, billing, maintenance, and inspection all read one unit record, the dispatcher confirms the carrier match, the standby hours reach the invoice, the mechanic services on real usage, and the bookkeeper closes without reconstructing the month. That single-record discipline is what keeps a hard-used breaker fleet honest.

How EquipFlow handles rammers on the dispatch board.

A Rammer is an attachment, not a self-powered unit, so the dispatch board has to pair it with a carrier that can actually run it. The single rule a dispatcher cannot skip is the match: the breaker's required oil flow and operating pressure have to fall inside the customer excavator's auxiliary circuit, and the breaker's working weight has to suit that carrier class. Send a breaker that wants more flow than the machine puts out and it hits soft; send one that takes too much and the customer cooks the seals. The board surfaces the carrier-weight range on the unit record so the dispatcher confirms fit before the truck leaves. Tool steel rides with it — the right point, moil, or blunt for the job, plus spares, since a worn-out tool on a remote pad is a lost day. The same breaker class books out fast during demolition windows, so conflicts show at assignment, not at the gate.

Billing rammers — MSA, standby, and site-level tax.

Breaker demand in the oilfield is mostly MSA-contracted, so the negotiated rate lives as an override on the customer record per equipment class rather than in a sheet the dispatcher keeps in their head. A rental created for that account picks up the right rate on its own. Breakers are also a textbook standby case: a hammer trucked to a pad sits idle billable through a rig delay or a weather hold, and the dispatcher marks standby so the invoice carries active and standby as separate lines without a month-end rebuild. Delivery, pickup, and any tool-steel or chisel charges ride the same invoice. Because a single demolition job can cross more than one county, tax jurisdiction is set on the delivery-site record so each site bills at its own rate. Invoices post to the accounting system on close.

Maintenance on rammers.

Breaker PM is hour-meter driven, not calendar driven, because a hammer pounding concrete daily burns an interval in weeks while a yard spare sits for a season. The catch with a breaker is that it often has no meter of its own, so the run hours are captured against the rental at the return inspection and posted to the unit record, where the maintenance module advances the service clock from real usage. Breakers live and die on grease and on the nitrogen charge: the lower bushing and tool are greased every couple of hours of work, and a low gas charge shows up as soft, slow hitting. Service leans on tie-rod torque, seal condition, bushing and tool wear, and the nitrogen check. Tools, bushings, and retaining pins are consumables and get tracked on the unit record alongside the work orders, parts, and meter history — which is also where a return-inspection damage charge becomes a repair ticket.

Rammer return inspections.

Two inspection rhythms apply. The operator-facing pre-use check is the customer's responsibility while the breaker is on rent — grease, tool condition, and no firing in open air. The yard's own control is the return inspection: before a Rammer comes off rent, the driver runs a mobile-web checklist on a phone — no app install — records the run hours against the rental, and attaches required photos that cannot be skipped. Breaker-specific checks carry the weight here. The lower bushing gets measured for play, the tool is checked for mushrooming and length wear, the tie rods are eyeballed for cracks that signal blank-firing abuse, the gas valve is checked for oil weep, and the hoses and quick-couplers are inspected for the leaks that let dirt into the circuit. The inspection ties to the rental record before the truck leaves the customer site, so a damage dispute has photos and a timestamp behind it.

What you give up running rammers in EquipFlow.

EquipFlow is a web app, so the return inspection needs a signal to load. On a remote pad with no coverage, a driver cannot finish the mobile inspection at the customer site; most yards run it at the yard on return instead, which means the photos and run hours land later than ideal. There is no built-in telematics today, and breakers rarely have their own meter anyway, so run time is captured at return rather than pulled from a carrier portal. The carrier-match check surfaces the spec ranges for the dispatcher to confirm; it does not auto-read a customer's specific excavator. A yard with an unusual billing structure should bring it to the demo to be scoped honestly.
