Lightweight and portable, flexible operation
A significant feature of small hydraulic drilling rigs is their lightweight and portable design. The overall structure is compact, relatively lightweight, and easy to transfer between different work sites. Some models of drilling rigs adopt modular design, which can be easily disassembled into multiple components. The weight of each component is within the range that can be manually transported, greatly improving the transportation convenience of the equipment in areas with inconvenient transportation such as mountainous areas and forests. For example, when conducting geological exploration in mountainous areas, workers can dismantle the drilling rig, transport the components to the work site by manpower or small transportation tools, and then quickly assemble them for drilling operations. Some small hydraulic drilling rigs are also equipped with wheeled or tracked walking devices, which have a certain degree of self mobility and can flexibly shuttle around the construction site without the need for additional handling equipment, further improving operational efficiency.
