Instructions
The YONDA SIR800 is a compact crawler drill rig for ground investigation, core drilling and specialized drilling tasks. Its compact footprint and hydraulically driven crawler undercarriage support on-site movement and positioning where working space is limited.
The configuration shown in the brochure features a YDR40 rotary head with a maximum torque of 800 Nm and a maximum rotation speed of 200 rpm. The listed core diameter is 50 mm, with a drilling depth of 80 m. Actual drilling capability depends on ground conditions, tooling, borehole diameter and the selected configuration.
The SIR800 can be equipped with a YONDA rotary head or hydraulic drifter to suit the required drilling method, with compatible tooling and auxiliary equipment selected for the application.

FAQ
1. What applications is the SIR800 designed for?
The SIR800 is designed for ground investigation, core drilling and specialized drilling tasks. Suitability should be assessed against the geology, required core size, borehole diameter, target depth and available working space.
2. What core diameter and drilling depth are listed for the SIR800?
The brochure lists a core diameter of 50 mm and a drilling depth of 80 m. These are configuration reference values; actual capability depends on the ground, tooling and operating conditions. Core diameter refers to the recovered core size, not the borehole diameter.
3. Is the SIR800 suitable for sites with limited access?
Its approximately 850 mm overall width makes it a compact option for sites with space constraints. Before deployment, check access width, ground bearing capacity, gradients, mast operating height and clearance for rod handling.
4. What information is needed for a quotation?
Please provide the application, ground conditions, borehole diameter, required core diameter, target depth and available electrical supply. If a particular coring method, drill rod specification or testing function is required, include these details so YONDA can assess the appropriate configuration.
