Cat PM622 Review: Match Your Milling Plan to the Road Ahead

The next surface starts with the cut beneath it. For contractors planning road resurfacing, the Caterpillar PM622 brings a useful combination to assess: half-lane cutting width, a tracked platform and a forward-loading conveyor. The buying decision becomes clearer when you connect that machine to your cut specification, trucks and finished-surface requirements.

Affiliate disclosure: Worksite Safety Hub may earn a commission if you purchase through the affiliate links in this review. This does not change the price you pay.

This research-based review explains PM622 applications, drum selection and the questions to bring to a supplier. A separate dated section records a used machine advertised in California, USA. We have not operated or inspected that individual unit.

A Cold Planer Built Around Pavement Removal

Caterpillar describes the PM622 as a half-lane milling machine for controlled removal of asphalt and concrete pavement. Its published cutting width is 2,235 mm (88 in), with a model maximum cutting depth of 330 mm (13 in). A project’s specified cut, material and required finish determine how those figures apply to the work.

For a resurfacing contractor, the value is in planning the removal stage as part of the whole job: establish the profile, recover the milled material and leave the surface ready for the next operation. Bring the PM622 into that conversation when its cutting width and working layout fit the proposed road section.

Start with the Surface You Need to Leave Behind

A clear milling brief gives the supplier something concrete to assess. Include the drawings, pavement layers, target depth, crossfall and any smoothness or texture requirements. Add the site layout and the available truck route.

These are planning examples, not a claim that one drum setup covers every specification. Ask the supplier to assess the actual rotor and machine against your work.

Standard Drum, Fine Milling or Another Setup?

The linked offer says the machine is equipped with a standard drum. That is the starting point for the enquiry: request the rotor identification, tool spacing, cutting width, bit and toolholder type, and current photographs of the complete cutting assembly.

Caterpillar’s PM622 literature documents System K rotor options for different cutting patterns, alongside other rotor configurations. For a specific finish, send the specification to a Cat dealer or the supplier and ask which compatible drum and tools are appropriate. Confirm any proposed change by machine serial number.

Price the package you intend to use. If your contracts call for another rotor, include the drum, associated parts, changeover arrangements and any required assistance in the quotation. An agreed inventory makes it easier to compare two offers advertised under the same model name.

Grade Control: Confirm the Complete Working Setup

Cat’s model literature describes Grade and Slope control and notes that full 3D milling requires additional hardware. For the advertised machine, ask which controls, displays, sensors, mounting hardware and reference equipment are supplied.

Have the supplier demonstrate the installed system and identify the operating manuals that apply. If you already use surveying or machine-control equipment, send the exact hardware and software details for a compatibility check. Confirm commissioning, calibration and operator familiarisation arrangements with the appropriate provider.

The question is practical: can the supplied package work with your project’s reference method and acceptance checks? A photograph of a display or a model-family feature list does not establish the complete installation.

Truck Loading Is Part of the Milling Plan

The PM622’s loading conveyor is central to the working layout. The published literature describes adjustable discharge speed and a folding conveyor arrangement. Request the actual conveyor configuration, working clearance and transport position for the offered unit.

Map the truck approach, exchange point and exit route before estimating daily output. Include the distance to the receiving facility, truck payloads, water replenishment and the time available within the traffic-management window. Discuss the result with the supplier and site team rather than treating maximum machine speed as a production forecast.

A simple quantity check helps frame that conversation: milling area × average removal depth = approximate in-place volume. For example, 1,000 m² at an average 50 mm cut is 50 m³ before allowing for changes in volume after milling. Use the project’s material data and approved haulage basis to convert this into loads; in-place volume is not a truck count.

Keep Build-Specific Features with the Correct Machine

The seller advertises a Cat C18 ACERT Tier 4f engine rated at 630 HP. Current Cat PM622 pages and later brochures cover other build and regional specifications. Use the identification plate and dealer records to establish the machine being supplied, including its engine, emissions equipment, rotor and controls.

Do the same for canopy, seating, cameras, lighting, spray equipment and any dust-abatement system. Ask for the fitted equipment list and a demonstration. Later model videos and current option lists are useful discussion references; they are not an inventory for this offer.

Inspection and Mobilisation

For a viewing, agree an inspection scope covering the engine and service records, rotor and toolholders, cutting chamber, conveyor belts and rollers, crawler assemblies and fitted control functions. Request the current hour reading and supporting maintenance documentation.

Include the water-spray and any fitted dust-control equipment in the demonstration. Have the responsible site team establish the operating method and controls using the correct manuals and project requirements.

For haulage, obtain confirmed transport dimensions and weight with the conveyor and canopy in their agreed positions. Identify fluid levels, loose tools, spare parts and any removed components. Caterpillar’s brochure distinguishes operating and transport weights; the carrier needs the basis that matches the actual shipment.

Seller Offer Snapshot — Checked 18 October 2026

This section records the individual offer reached through the supplied affiliate URL. Reconfirm availability, price, current hours and equipment inclusions when contacting the supplier.

Product-location note: This review follows the product-specific California field confirmed by the supplier. It does not use the seller’s contact address as the machine’s collection site.

Delivery Areas and Shipping Terms

Omnia advertises worldwide shipping and says it has shipped machinery to more than 100 countries. This is general service coverage; confirm this machine’s route and your proposed delivery point with the supplier.

Its shipping page describes road transport, RoRo, LoLo and container services, with assistance for documentation and marine insurance. For RoRo, it specifies that the machine must be driveable and thoroughly cleaned. Ask which method suits the complete shipment, including spare drums or tools if purchased.

The checked offer does not state a fixed freight price, delivery time, destination list or named Incoterm. Request an itemised quotation covering collection, inland haulage, port handling, freight, insurance, customs responsibilities and unloading. Confirm whether the agreed delivery ends at a port or your site and identify charges payable separately.

Inspection, Payment and Purchase Conditions

Omnia’s FAQ encourages inspections and offers OEM or independent inspection arrangements. It states that used machinery is sold without warranty. Request the individual inspection report, working video, maintenance records and final contract terms.

The FAQ describes payment mainly by wire transfer before shipment, with Letters of Credit or Cash against Documents available in some circumstances. It also mentions a negotiable 10% deposit for a 30-day reservation. Confirm the payment schedule and deposit conditions for this transaction in writing.

Watch the PM622 on an Airport Resurfacing Project

Watch Cat Paving’s PM622 airport project video. This manufacturer video shows PM622 machines using 3D control on an airport runway resurfacing project. It illustrates a model application, not stock US2113. The demonstrated 3D equipment is not confirmed as included in this offer; ask for the fitted control inventory.

Questions Buyers Ask Before Contacting the Seller

What is the PM622’s milling width?

The manufacturer publishes 2,235 mm, or 88 in. The offer’s 7 ft 4 in description is the same nominal width. Confirm the actual installed drum for your purchase.

Is the advertised machine ready for fine milling or 3D control?

The seller lists a standard drum. Ask for the rotor identification and fitted control inventory, then request a project-specific proposal for any additional equipment.

Can the supplier deliver to my country?

Omnia advertises worldwide shipping. Provide your destination and ask for written route confirmation, the delivery basis and a complete cost breakdown.

What should I include in my first enquiry?

Try: “I am interested in PM622 US2113 for [surface, cut depth and finish requirement]. Please confirm the serial number, current hours, drum specification, grade-control equipment, inspection availability and delivered quotation to [destination]. I can provide the project layout and milling specification.”
