Litian shank adapters select high-quality alloy structural steel as raw materials, adopt advanced thread manufacturing technology and surface treatment technology, and are manufactured according to precise tolerances, which can minimize the loss of impact energy during the transmission process. Our shank adapters are applicable to various brands of rock drills, such as Sand vik (Tomrock) rock drills: HL300, HD400, HL500, HL600, HL700, HL850, HL1000, HL1500, HLX5, RD520 series, etc.

Top hammer shank adaptors, the role of which in rock drilling is to directly bear the impact energy and torque of the rock drill, and is used to transfer the energy from drill rig to drill rod. One end of the shank adaptor is connected to drill rig, and another end is connected to drill rod, so that the energy of drill rig can be transmitted to drill bit, and finally achieve the purpose of drilling.

Litian shank adapters use high-quality alloy structural steel, and adopt a complete set of mature technology such as advanced surface treatment technology, smelting technology, and mechanical processing technology, which can greatly reduce the loss of energy in transmission and make the rock drilling speed fast.

MF rod, also known as speed drill rod, has a male thread at one end and a female thread at the other end. It can directly connect to the shank adapter without the aid of a coupling sleeve, which eliminates the defect that the equal diameter thread connection is prone to vibration. The quick-change properties of male/female rods improve the overall drilling efficiency.

In quarry and aggregate industries, the application of top-hammer rock drilling rigs can improve operational efficiency, safety and stability, as well as adapt to the increasingly stringent emission reduction and environmental protection standards.
