Explosion-proof certified climbing robot — high-pressure water cleaning (50 MPa pump). The JT-1 is Jingtao’s compact platform for hazardous-area tank and vessel cleaning. Magnetic wheel adhesion with 2,500N holding force. Eliminates human confined-space entry entirely.
Not every tank is a 30-meter crude oil storage tank. Inside refineries, chemical plants, and offshore platforms, hundreds of smaller vessels — day tanks, separators, knock-out drums, process columns — require regular internal inspection and surface preparation. These assets share one dangerous characteristic: confined space classification. Entry requires gas monitoring, ventilation, harnesses, standby rescue teams, and 45-minute work-rest cycles per worker.
The Jingtao Energy JT-1 Mini eliminates human entry for these applications. Its compact magnetic-wheel chassis navigates through 600 mm manways — The standard access port on most pressure vessels — and operates on internal tank walls where larger robots simply cannot fit. With 2,500 N magnetic holding force and GB Ex db ib IIB T4 Gb explosion-proof certification, the JT-1 Mini brings robotic surface preparation to the hazardous-area vessels that have historically been exclusively manual-confined-space jobs.
| Application | JT-1 Mini | JT-2 Full-Size |
|---|---|---|
| Minimum access opening | 600 mm (manway) | 800 mm |
| Internal vessel work | Designed for internal | Limited by size |
| External tank shells | 150 m²/day | 300 m²/day |
| Explosion-proof cert | GB Ex db ib IIB T4 Gb Zone 1 | Ex db ib IIB T4 Gb (GB/T 3836) |
| Weld seam crossing | 5 mm | 8 mm |
| Payload capacity | 25 kg | 45 kg |
Internal Tank Inspection & Light Surface Prep: Enter through the manway, visually inspect weld seams and shell thinning, then perform light spot blasting or coating removal on identified corrosion areas — all without human entry.
Process Column Maintenance: Chemical plant distillation columns with trays and demister pads — The JT-1 Mini’s compact profile navigates between internal structures that block larger robots.
Offshore Platform Vessels: Helideck fuel tanks, firewater tanks, and produced water vessels where deck space is premium and scaffolding is prohibited by platform weight limits.
Emergency Response: Deployable through a single manway within 30 minutes — no scaffolding, no crew briefing, no confined-space permit chain. Critical for unplanned shutdown inspections.
| Water jet pressure | 50 MPa (high-pressure cleaning pump) |

The JT-1 series includes four variants for different applications. Contact our engineering team for a detailed comparison and recommendation based on your specific operating conditions.
Explore the full series: JT-1 Mini | JT-1-F | JT-1-H | JT-2.
All JT-1 variants share a common technology platform: permanent magnetic wheel adhesion, remote control operation, modular end-effector interface, lightweight aluminum frame, and tether-powered operation with no battery limits. This platform approach ensures consistent performance, simplifies spare parts management, and allows operators to cross-train on multiple variants.
