The model name is only the first level of filtering
Buyers often treat T35 and T40 as a simple choice between the smaller and the larger machine. That is useful directionally, but the actual purchase depends on the rock drill, thread system, rod length, rod magazine capacity, engine version, dust collector and market configuration the machine is equipped with. Two machines bearing the same designation may have different working limits and different parts requirements.
Start with the blasting plan and your current tooling. If your quarry already uses a specific thread, rod length and bit series, changing systems adds inventory and training costs. For a new operation, compare complete drilling packages and local support rather than retaining a tooling system you do not yet have.
Where T35 typically applies
The FlexiROC T35 currently listed by Epiroc is intended for quarrying and civil engineering, uses top-hammer drilling and has a published hole-diameter range of 64–115 mm. The official brochure also lists different options; the actual configuration should be verified. For many buyers, the T35 is attractive when access, mobility and small-to-medium production holes matter more than working at the upper end of the T40 range.
These figures describe the current model. Confirm the installed rock drill, drill-rod thread, feed length and optional configuration from nameplates and close-up video. A seller’s claims about daily advance can be recorded as statements, but should not replace testing in representative rock or a condition-based assessment.
When you need the configuration headroom of T40
The current FlexiROC T40 brochure lists a recommended total range of 64–127 mm, with the specific range depending on the rock drill and thread fitted. Where projects frequently move on to larger blast holes, or where the buyer wants more configuration headroom, this wider range can make the T40 the better choice.
Headroom comes at a cost. Buyers should compare transport weight, fuel and service requirements, rock-drill repair risk, and the price of the correct drill rods and bits. If nearly all production falls comfortably within the range of the verified T35 configuration, a larger nominal figure alone does not create value.
Hours must be listed separately by component
A single hour reading can conceal several parts of a machine’s history. Engine, impact or drilling, and compressor or system hours may be recorded differently, and meters may also have been replaced. Ask the seller for continuous footage taken under safe conditions showing the machine nameplate and readable counters, then cross-check them with service records, controller logs and visible wear. Qualified personnel should inspect and start the machine according to the applicable manual and site safety requirements; carry out a cold start according to the manual only when conditions permit.
Local materials include machines labelled T35 and T40, with sellers reporting rock-drilling hours or engine models, depending on the machine. These descriptions are leads to investigate, not independently verified facts. An inspection should assess whether wear is consistent with the claimed history and whether service evidence exists for components carrying higher repair risk.
First, check the expensive top-hammer components
The rock drill, feed and rod-handling systems deserve more attention than fresh paint. Qualified personnel should follow the applicable manual and site safety requirements to inspect for leaks around the rock drill, shank adapter and hoses, and check feed beam straightness, guide clearance, chain or wire-rope condition and rod supports under safe conditions. Checks involving machine movement, such as rod-magazine indexing and boom movement, should follow the manual only where machine and site conditions permit.
- Identify the rock drill model and photograph its nameplate
- Where applicable, confirm the T38, T45 or T51 tooling; do not infer the thread from the rig nameplate
- Where machine and site conditions permit, have qualified personnel perform applicable repeated rod-handling checks according to the manual; do not rely only on footage of a single operation.
- Check the dust collector's suction, filter condition and pre-separator
- Record the condition of the tracks, undercarriage, cab safety and visible structural repairs
Comparing complete landed solutions
A meaningful comparison lists everything included at the point of departure. Confirm the starting drill rods, extension rods, drill bits, shank adapters, coupling stock, tools, manuals and critical spare parts. Ask which items are used, new or not included. Then add inland transport, dismantling costs if required, port handling, ocean freight, insurance, import costs and recommissioning costs at the destination.
Transport dimensions must be measured on the actual configuration. Published dimensions are useful for planning, but may not reflect the guards, optional equipment, drill rod racks or transport preparation on this used machine. A low ex-factory price may disappear after replacing tools and rush-shipping missing parts.
Choose T35 or T40 by project
Choose the verified T35 configuration when its hole-diameter range covers the actual project with margin, site access conditions are better suited to the smaller class, and the available machine has stronger evidence of its condition. Choose the verified T40 configuration when larger hole diameters or more demanding production requirements occur often enough to justify its capability, and the supporting tools and service plan are acceptable.
For a GLOBMACH comparison, please provide the hole diameter, depth, rock, bench access, current thread and destination port. We can return a short list of current units, clearly noting configuration differences, and then offer a live video or on-site inspection plan.
