- The upper and lower balls act as valves, creating a double-check ball system that prevents the collected groundwater from being lost. - Water that enters above the valve is drained before it is pumped to the surface. - It can be maintained and reused, contributing to the SDGs!

The "Crawler Drill zekeR" is a small-sized boring machine that operates with full hydraulic drive and rotary impact. It is self-propelled, allowing it to ascend and descend using walking boards even on trucks without lifters. By adjusting the rotation and impact with engine RPM and valves, it can provide optimal conditions for the ground and sampler, enabling efficient work. It can be utilized in areas where the surface is covered with concrete, where rubble is laid out, or in gravel layers that are said to be difficult for boring. 【Features】 ■ Ultra-lightweight and compact design ■ Highly efficient operation even in narrow fields due to its maneuverability ■ Perfect for fieldwork compliant with soil contamination countermeasures law ■ Suitable for sample collection and observation well drilling ■ Impact rotation capability can be adjusted in conjunction with engine RPM *For more details, please feel free to contact us.

We would like to introduce our company’s manufactured and sold hole drilling and soil sampling tool, the "Double Shovel." With a mouth diameter of approximately 150mm, it is designed to allow for excavation up to 1 meter deep. This is made possible by a slim tip plate, a high pivot point, and a mechanism that opens the tip plate when the handle is opened and closes it when the handle is closed. Instead of lifting while applying outward force to avoid dropping the grabbed soil, it allows you to grab the soil while the handle is closed, enabling retrieval from narrow and deep holes. 【Features】 ■ Ultra-slim ■ Can dig a hole approximately 1 meter deep with a mouth diameter of about 15 cm ■ A "long type" that can excavate up to about 1.5 meters is also available ■ An optional "striking plate" for driving is also provided *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our hand tool "Pick" that we manufacture and sell. It solves problems such as "I can't collect soil samples because the ground is too hard" and "The crushed stone is compacted, and the excavation work is not progressing as planned." Please try the loosening effect by striking the rear end of the handle with a hammer to drive in and rotate the pick. Additionally, we accept custom orders, such as changing the width of the blade, to meet customer requests. Please feel free to contact us when placing an order. 【Specifications】 ■ Total length: 1,060mm ■ Total width: 300mm ■ Blade width: 50mm ■ Weight: 4kg * For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our soil sampling tool specifically designed for the Daiki hand auger, the "Core Tube & Casing." Do you have any concerns such as: "It's a soft and easily excavated stratum, yet I can't collect samples" or "It's only a 2-3 meter observation well, but it's highly collapsible and I can't insert the well casing"? By simply replacing the blade of the hand auger with the core tube set, you can solve the issues mentioned above. We also sell the Daiki hand auger, so please feel free to contact us. 【Features】 ■ Specifically for the Daiki hand auger ■ Just connect it to an existing hand auger ■ Attach a basket to the core bit to prevent the collected soil from falling *For more details, please refer to the PDF document or feel free to contact us.
