350 m crawler water-well drilling rig
A crawler water-well catalogue entry with reported 350 m depth. Its usable project envelope depends on bore diameter, formations, drilling method and the matched compressor/tool string.
Read the reported figures with their unresolved conditions
The detailed source is more useful than the category headline.
The official 350 m page identifies a crawler water-well rig and labels an illustration “SR350”. Its description reports the figures below. [1] This is the recorded catalogue entry; other depths and power configurations in the category are separate products. [2]
| Source item | Reported value | Before purchase |
|---|---|---|
| Hole diameter / depth | 140–325 mm / 350 m | Obtain diameter–depth–formation and method conditions; the ranges are not a universal guarantee. |
| One-time advance | 6.6 m | Confirm mast/pipe handling configuration and usable stroke. |
| Walking speed | 2.5 km/h | Confirm ground/operating conditions; not a road-transport specification. |
| Air pressure / consumption | 1.7–3.3 MPa / 17–35 m³/min | Require matched duty points and compressor selection. |
| Swing speed / torque | 55–115 rpm / 6,200–8,500 N·m | Confirm operating modes; do not assume maximum speed and torque occur together. |
| Pipe lengths | 1.5 / 2.0 / 3.0 / 6.0 m | Specify ordered lengths, connections and mast compatibility. |
| Dimensions / weight | 5,900 × 2,000 × 2,850 mm / 9,000 kg | Obtain the transport-state drawing and included-equipment list. |
Three source labels need clarification
The page prints “Equipped capacitor: 84KW”, “Climbing angles: 30Max” and pipe diameter “89mm /102 m”. [1] The first is not clearly identified as engine input/output; the second lacks a stated unit; the third contains an apparent unit error. We do not silently turn these into an 84 kW engine, a 30° slope rating or an approved 102 mm pipe. Request a corrected, revision-controlled sheet.
Match delivered air to the proposed drilling method
The source supplies air-demand ranges and links separate compressor products. Neither a compressor model nor its inclusion in the rig price is established. [1] Make the combination visible in the quotation.
Send the application
Provide depth, hole diameter, formations, drilling/flushing method, elevation and ambient conditions. Identify the proposed hammer, bit and drill string so the supplier can state the duty basis.
Request a matched schedule
Require compressor identity, delivered flow at the selected working pressure and site conditions, hose/connection scope and operating limitations. A maximum-pressure headline beside a maximum-flow headline is not proof of the requested combined duty.
Keep rig and compressor engine configurations separate, including fuel, service and destination requirements. If a different drilling method is proposed, ask which pump/flushing equipment is required rather than assuming a water-and-air configuration from another entry applies here.
Turn pipe options into one compatible tool string
- Controlled interface scheduleConfirm pipe diameter, length, connection, hammer and bit for the offered model. Resolve the source’s “102 m” wording on the corrected sheet.
- Handling and advancing arrangementReconcile chosen pipe lengths with the mast, stroke, positioning and handling equipment. The listed 6.6 m advance does not itself define a safe handling procedure.
- Purchased quantitiesSpecify included pipes, bits, hammers, couplings and starting spares. Keep consumables, rig equipment and optional service tools as separate offer lines.
The page describes a positioning disc and hoisting mechanism. These statements do not replace an operating manual, lifting plan or site-specific procedure. Obtain documents for the ordered configuration and trained operating responsibilities.
Agree transport and acceptance before dispatch
The stated dimensions and 9,000 kg weight do not clearly define folded/working state or included equipment. A carrier’s legal transport, loading and site access must use the final dispatch configuration and drawing.
| Checkpoint | Evidence to agree |
|---|---|
| Configuration freeze | Rig serial/model/revision, engine, mast, carrier, compressor and tool schedule. |
| Pre-delivery acceptance | Defined functional/hydraulic checks and recorded results; any drilling trial needs its own conditions. |
| Shipment | Transport drawing, final weights, securing/unloading responsibilities and package inventory. |
| Site handover | Commissioning, training, manuals, trial conditions if contracted and site-preparation responsibility. |
| Support | Model-specific spares, service response, warranty coverage/exclusions and maintenance requirements. |
Sanrock’s company page describes assembly/testing and claims ISO 9001/CE certification. [3] This review has not authenticated the certificates or a model-specific conformity file. Request holder/site/scope/validity and exact machine/destination documents separately.
Does 350 m mean any 325 mm bore can reach that depth?
The source does not give that paired condition. Obtain the depth-versus-diameter and formation/method basis for your project.
Is this a truck-mounted drilling package?
The recorded entry is crawler equipment. Its prose discusses possible truck mounting but does not define an included truck or approved installation. Quote a transport-mounted proposal separately with its configuration documents.
Can a 500 m or 700 m entry fill missing specifications?
No. Those are separate entries. Missing engine, lift, interface or performance details must be returned for this offered rig.
