Benefits & Features
Left-handed threaded steel rock bolt, also known as left-handed rock bolt or left-handed rock bolt for mining, is mainly used in the field of tunnel and surrounding rock reinforcement in coal mines, railways, hydropower and other projects. This product is made of left-handed fine-rolled threaded steel with a continuous full-thread structure, which can be combined with rock bolt support plates and nuts to form a three-way force system.
Product Features:
(1) Reasonable structure, the rock bolt has equal strength in the entire thread and length, which solves the shortcomings of low strength of the reverse twist rock bolt thread and flattening part.
(2) The load-bearing capacity is 40% higher than that of the reverse twist rock bolt of the same specification
(3) Simple operation and low price, widely used in various tunnel support of coal mines, railways, hydropower and other projects. Product advantages:
(1) No machining is required for the anchoring end and the fastening end;
(2) Equal strength along the entire length, high material utilization rate;
(3) Large anchoring force;
(4) Equipped with prestressed gaskets, making it easy to control the installation quality;
(5) Fast installation speed, etc. It is a new type of rock bolt that saves materials, labor, and has equal strength. Right-hand threaded steel rock bolts have broad prospects for promotion and application.
