Ericco (Shaanxi Ericco Inertial Technology Co., Ltd.) will exhibit at bauma CHINA 2026, the International Trade Fair for Construction Machinery, Building Material Machines, Mining Machines and Construction Vehicles, on stand E5.272 at the Shanghai New International Expo Centre. From 24 to 27 November the company will present fourteen MEMS-based products for north finding, gyro orientation and borehole inclinometry, covering mine borehole alignment, site investigation, trenchless drilling and measurement-while-drilling work.
What bauma CHINA 2026 looks like this year
bauma CHINA has run in China since 2002 on a two-year cycle and is the region's largest platform for construction and mining machinery. The 2026 edition is the first to use a dual-venue format: the Shanghai World Expo Exhibition & Convention Center from 23 to 26 November and the Shanghai New International Expo Centre from 24 to 27 November, together reaching 400,000 square metres of exhibition space, with more than 4,000 exhibitors expected from over 30 countries and regions.
The scale is worth putting in numbers. The 2024 edition drew 3,542 exhibitors from 32 countries and regions and 281,488 trade visitors from 188 countries and regions across 330,000 square metres. For a supplier of inertial sensors and survey instruments, that is one of the few places where OEMs, drilling contractors and mine operators can be met in the same week.
On the stand: four groups, one workflow
The stand follows a working sequence rather than a catalogue. Borehole orientation instruments establish the opening direction; north finders provide a true-north reference; orientation subs carry that reference downhole in a tool-sized housing; and trajectory survey and MWD systems reconstruct the path while drilling. All four groups share the same MEMS gyro and accelerometer device platform, so a visitor can select by hole size, operating temperature and protection class instead of by product family.

Three engineering fit points are worth a closer look on the stand. The YHZ90/360 series is built for intrinsically safe use underground, where working space is tight and an external magnetic reference cannot be trusted. Sub 19 and instrument 21 address holes where casing, drill string and iron-rich formations make fluxgate readings unreliable. Sub 15 and sub 29 push two limits at once: 18.6 mm for slim assemblies, and 150 °C for hot sections. Accuracy, measuring range and interface figures are best confirmed against the datasheets on site.
Three questions we expect to discuss
Three questions come up in almost every conversation, and they are the ones our engineers will be ready to work through at the booth. First, how to obtain an opening azimuth underground without relying on the earth's magnetic field. Second, how to weigh gyro against fluxgate, and how to combine them, in holes where casing and steel are both present. Third, how to match sub diameter, temperature rating and mounting method to slim or hot sections. Visitors are welcome to bring their hole parameters and work through a first-pass selection on the spot.
Visiting details
The stand is open for the full run of the show to OEMs, drilling and geotechnical contractors, mine operators and international buyers. Letting us know your visiting window and the product line you care about in advance helps us make sure the right engineer is there when you arrive.

Registration
|
Visitor pre-registration is open on the show website; ticket terms follow the organiser's current notice
|
Pre-registering on the show website normally removes the on-site ticket fee, though the terms are time-limited and the organiser's current notice governs. If Shanghai is out of reach this month, the same product information is available by phone or WeChat, and stand materials will be sent out after the show.
North finding and MWD look like different product lines, but they answer the same question: turning an invisible direction into a repeatable number. From 24 to 27 November, at E5.272 in the Shanghai New International Expo Centre, we would rather spend the time getting your hole conditions right. Precise Positioning, Intelligent Future.
