Double Telescopic Roof Support Leg

01 | KEY TECHNICAL ATTRIBUTES

1. Product: Double Telescopic Roof Support Leg

2. Sourcing brand: TAIDA GLOBAL (procurement coordination platform; not a claim to be the equipment manufacturer or an authorized brand agent).

3. Category: Hydraulic Cylinders, Legs & Jacks

4. Typical application: height adjustment of medium-seam supports.

5. Proposed first-stage bore: 220 mm.

6. Proposed total telescopic stroke: 2000 mm.

7. Functional configuration: two-stage telescopic sleeve leg.

8. Critical technical interfaces and compatibility: bore and rod diameters, mounting dimensions, stroke, pressure class, sealing and valve compatibility.

9. Factory inspection / FAT / SAT focus: pressure and leakage testing, reciprocating movement, surface finishing and dimensions.

10. Site safety: Never substitute a high-pressure hydraulic cylinder based only on apparent size; verify strength and fail-safe behavior.

11. Utilities and controls: confirm actual operating voltage/frequency, hydraulic fluid, connectors and protocols; do not assume 380 V/50 Hz.

12. Request a current manufacturer datasheet, drawings, material and test records, relevant certificates and agreed FAT/SAT checklist.

13. Specification status: These values are planning targets or illustrative procurement criteria, NOT a confirmed supplier specification or inventory claim.

14. Manufacturer and country of origin: not verified; do not infer them from the third-party reference site.

02 | REGIONAL SHIPMENT & DELIVERY GUIDANCE

1. Production lead time: unconfirmed until a manufacturer supplies a written production schedule; include design, material procurement, fabrication, tests, inspection and packing.

2. Shipment: Double Telescopic Roof Support Leg. Confirm actual packed dimensions, per-piece gross weight, split modules, handling, hydraulic fluid, battery and hazardous-goods rules.

3. Historic ordinary sea-freight ETD-to-ETA reference ONLY (from an older crane template; NOT verified 2026 sailings or equipment-specific quotes):

  • Southeast Asia: Shanghai → Surabaya, Indonesia; indicative 12–20 days.

  • East Asia: Shanghai → Incheon, South Korea; indicative 3–8 days.

  • Middle East: Shanghai → Khalifa Port, UAE; indicative 18–28 days.

  • Africa: Shanghai → Tangier, Morocco; indicative 32–50 days.

  • Europe: Shanghai → Hamburg, Germany; indicative 36–53 days.

  • Americas: Shanghai → Vancouver, Canada; indicative 15–26 days.

4. These ranges must NOT be used for contractual delivery commitments or special/out-of-gauge cargo without fresh carrier quotations.

5. Inland transport in China, customs, export handling, loading, booking queues and origin-port time are excluded.

6. Breakbulk, open-top/flat-rack, oversized machinery, batteries and explosion-protected electronics may require different handling and transit.

7. Port discharge, import clearance, taxes, last-mile delivery, mine entry, installation, commissioning and SAT are excluded. Confirm Incoterms, route and schedule in writing.

03 | CUSTOM OPTIONS & PROCUREMENT HIGHLIGHTS

1. Define the application: height adjustment of medium-seam supports. Confirm site operating loads, interfaces and local requirements before requesting a configuration.

2. Primary selection criterion: Proposed first-stage bore: 220 mm; verify engineering calculations and applicable test conditions.

3. Secondary selection criterion: Proposed total telescopic stroke: 2000 mm; match component capacities, materials and safety margins.

4. Core functional focus: two-stage telescopic sleeve leg; identify which parts are standard versus optional/custom supply.

5. Interface and replacement requirements: bore and rod diameters, mounting dimensions, stroke, pressure class, sealing and valve compatibility. For a replacement part, supply OEM model, part number, drawings, mounting dimensions and site photos.

6. Pre-quote technical comparison should explicitly address pressure and leakage testing, reciprocating movement, surface finishing and dimensions; document deviations to avoid rework and mismatched interfaces.

7. Optional scope (subject to quotation): equipment/components, connection pieces, inspection records, spare parts, commissioning assistance and operator training.

8. Evaluate total cost of procurement: equipment, spares, consumables, inspection/compliance, packing, insurance, freight, installation, energy use and downtime. No unverified cost-saving percentage is claimed.

9. Engineering safeguard: Never substitute a high-pressure hydraulic cylinder based only on apparent size; verify strength and fail-safe behavior.

04 | FREQUENTLY ASKED QUESTIONS

Q1. Is Double Telescopic Roof Support Leg suitable for height adjustment of medium-seam supports?

A1. Check proposed first-stage bore: 220 mm and proposed total telescopic stroke: 2000 mm, then assess bore and rod diameters, mounting dimensions, stroke, pressure class, sealing and valve compatibility against the real mine or plant duty. A product name alone does not establish suitability.

Q2. Are the listed figures for Double Telescopic Roof Support Leg guaranteed specifications or stock availability?

A2. No. These values are planning targets or illustrative procurement criteria, NOT a confirmed supplier specification or inventory claim. Request written supplier confirmation, latest approved drawings, performance guarantees and manufacturing schedule.

Q3. What should be reviewed during supplier audits, FAT and SAT for Double Telescopic Roof Support Leg?

A3. Review pressure and leakage testing, reciprocating movement, surface finishing and dimensions; also verify records, identification, traceability, relevant approvals and site-specific acceptance criteria.

Q4. What information is needed to request a quote for Double Telescopic Roof Support Leg?

A4. Provide the intended duty (height adjustment of medium-seam supports), required proposed first-stage bore and proposed total telescopic stroke, drawings, power/hydraulic interfaces, installation constraints, order quantity and destination country. Replacements need original equipment drawings.

Q5. Can the regional shipping intervals above be used as guaranteed delivery dates?

A5. No. They are historical ordinary-ocean-freight illustrations, not verified schedules. The manufacturer and forwarder must confirm actual packing, carrier, Incoterms, dates and any special-cargo restrictions in writing.
