Advantages of whole machine mobile transportation

The whole machine weighs about 18 tons and can be transported as a whole with a rod. It can be transported by a single bridge trailer with two front and eight rear axles, without the need to disassemble the drill pipe. It has fast transfer and low cross regional transportation costs; The track width is 2.5m, the body is compact, and the narrow field has strong traffic capacity.
The maximum working height is about 11m, and construction can be carried out under high bridges, inside factories, and in narrow courtyards in villages and towns, specifically suitable for narrow working conditions where large rotary excavators cannot enter.

Rock penetration and construction capability

The diameter of the borehole is 0.4-2m, with a maximum drilling depth of 17m. The power head has sufficient torque and can handle strongly weathered and red sandstone, as well as some moderately weathered rock layers. It has outstanding rock penetration ability in small rotary excavations of the same tonnage, taking into account both soil and soft rock layers. It is suitable for building piles, photovoltaic power grid piles, support piles, and small bridge pile foundations.

Fuel consumption and hydraulic system

The whole machine is matched with an efficient power hydraulic system, and the actual hourly fuel consumption on the construction site is low, with controllable operating costs; Load sensing hydraulic matching, smooth operation, minimal impact, suitable for long-term continuous pile driving operations.

Reliability and Maintenance

The Longgong whole machine platform has strengthened the frame, rotation, and track chassis, resulting in a lower failure rate compared to workshop style small rotary excavators; The hood has a large opening space, and the filter element, pipelines, and engine are easy to maintain and repair. The spare parts market has a large inventory and are easy to find, with a good resale value.
