400 m Crawler Rig Maintenance: Confirm the Schedule

Which machine this page covers

This page concerns the 400 m crawler configuration linked below, not every machine sold with a 400 m depth claim or an ST400 label. The source identifies a Yuchai-powered crawler rig with hydraulic and rotary systems. Those descriptions help organise the documentation request; they do not identify the engine variant or the service instructions for an installed machine. Record the actual rig and component nameplates before matching documents.

What the manufacturer page actually establishes

In its maintenance-related FAQ, the supplier refers regular maintenance to the service manual and asks buyers to contact it for specific intervals. The public page provides no complete interval table, lubricant schedule or revision-controlled repair procedure. A continuous-operation statement elsewhere in the listing is not permission to defer an inspection or scheduled service. It must not be converted into an operating or maintenance approval for your machine.

Build separate component records

Use separate entries for the rig, engine, hydraulic/rotary assembly and crawler equipment. If an air compressor, mud pump or hammer is fitted, identify it separately. Ask the responsible supplier which manual governs each system and which work requires its technician or another competent person. A rig brochure cannot replace the component manufacturer instructions, and a general engine brand cannot select an oil or filter.

Resolve the service schedule before entering due values

Request the manual title, document number, revision, issue date and applicable model/serial range. For each task ask for its page reference, stated operating-hour or calendar trigger, relevant working-condition changes and required personnel. Also request the approved fluid/part references, any applicable quantities, disposal instructions and the approved preparation and return-to-service procedure. Keep each answer tied to the actual configuration rather than a similar crawler rig.

Use the record without inventing a starting point

Enter the equipment identity and manual reference first. Leave interval and next-due fields blank or explicitly marked unconfirmed until the corresponding instruction has been verified. A missing service history should be referred to the responsible supplier or competent maintainer; do not reset the history simply by recording a new date. The worksheet stores information and does not certify equipment condition or approve continued operation.

Keep circulation equipment separate from rig fitment

The BW250 and BW400/10 pages below are related circulation procurement routes. Their presence does not show that either pump is installed, included or compatible with this rig. Identify the actual pump, drive and connection details, then obtain its own parts book and maintenance instructions. The same boundary applies to a compressor or DTH tool. A complete package quotation should identify which party supplies each document and service item.

Prepare a useful supplier question

A useful request identifies the exact rig and engine serials, the installed auxiliary equipment, the current meter units/reading, the available manuals and the specific missing maintenance information. If a fault already exists, use the service-request record to describe observations already available. Do not run faulty equipment, expose a pressure line or remove guarding just to collect material for an enquiry. RigSpan coordinates the request; the actual technical response and any service scope require confirmation.

What is established and what still needs confirmation.

Use the editable record.

Download the CSV and open it in spreadsheet software. It contains column headings with no invented equipment details or service intervals. Add a row for each equipment identity, maintenance task or fault report as appropriate. Keep uncertain items marked for confirmation.

Editing the file stays on your device. This website has no file-upload form. The enquiry form prepares a text summary; if you want to share a completed file, review it and attach it yourself in WhatsApp after deciding what to send.

Keep the three records together.

• Equipment Identification Guide · Equipment Identity CSV
• Maintenance Records Guide · Maintenance Record CSV
• Service Request Guide · Service Request CSV

These are editable records, not manufacturer service manuals. Enter manual references and approved values only after verification.

Sources and limits.

Shitan — 400 m crawler rig product page — Publication date not stated; accessed 18 October 2026. Catalogue evidence for the described crawler configuration, engine and hydraulic/rotary systems. The FAQ refers maintenance intervals back to the service manual and supplier; it does not publish a usable service schedule.

The identification fields, worksheets and enquiry sequence are RigSpan editorial aids. They are not manufacturer-issued instructions, service approval or proof of an authorised repair network. Specific intervals, oil grades, quantities, torques and settings require the applicable manual and competent review.
