Recently, Zoomlion delivered the first ZR255H rotary drilling rig in Panama. After being put into use, its outstanding performance and high efficiency won praise from the customer.

     The ZR255H rotary drilling rig was first deployed for pile foundation construction of a building project in Panama City and immediately demonstrated strong construction capability, efficiently completing pile holes with a diameter of 1.2 meters and a depth of 25 meters. The project geology is mainly clay, with a mudstone layer of about 50 MPa at the bottom. With its adaptability to both soft and hard strata, the ZR255H balances construction speed and fuel consumption through an efficient hydraulic system. Combined with a multi-gear power head design, it easily tackled the highly weathered rock layer and completed drilling of a single hole in just 3 hours, impressing the local team with its efficiency.

     The person in charge of the project not only recognized Zoomlion's products but also highly affirmed the company's full-process service support system.
