Convenient transit‑site movement SR155 Rotary Drill Rig

Flexible and adaptable, with low transition costs

The whole machine weighs about 48 tons, with a compact appearance and can be transported without exceeding the height limit. It can be transported by ordinary flatbed trucks and disassembled quickly. Suitable for narrow urban construction sites, mountainous power tower foundations, and small pile foundations in urban villages. The internal displacement of construction sites is flexible, and frequent transitions have obvious advantages

Energy saving economy, low operating costs

Equipped with an intelligent power distribution hydraulic system, it outputs power as needed and has a low average fuel consumption in actual testing. Compared to medium and large models, the purchase, maintenance, and accessory costs are lower, making it suitable for small and medium-sized pile foundation projects with a shorter payback period.

Stable construction efficiency

Rated torque of 155kN · m, fifth generation power head, smooth composite action, fast lifting speed of the main hoist, good control of hole verticality, and an efficiency about 15% higher than that of the same level; The standard maximum pile diameter is 1.5m and the maximum depth is 56m. The construction performance of soil and sand layers is excellent. Combined with the Sany construction method, shallow hole large-diameter graded drilling can be achieved (such as the 2.4m shallow power pile)
