Award-winning product: Zoomlion ZR550G rotary drilling rig 
Award-winning company: Shanghai Zoomlion Piling Machinery Co., Ltd.  

Award details: The Zoomlion rotary drilling rig ZR550G is equipped with three slewing reducers, which can effectively enhance braking performance during rock drilling, improve the stability of the entire machine when penetrating rock, and ensure drilling accuracy; the optimized design of the main winch features a bottom-touch protection function that simulates the operation of an experienced operator to automatically prevent rope tangling; it also has a short-stroke function at the hole bottom, which reduces speed step by step before the drilling tool is lowered to the hole bottom, avoiding a large instantaneous impact when the drilling tool touches the bottom, protecting the hydraulic pipeline system while also ensuring the stability of the entire machine. Its most distinctive feature is its large cross-section mast, mast cylinder, and large-diameter slewing support, which make construction more effortless in high-verticality projects.
