A “bolting machine” is a tool used to install, tighten, or remove bolts, typically in industrial, mining, construction, and manufacturing settings. There are different types of bolting machines, each designed for specific applications.
Types of Bolting Machines
1. Rock Bolting Machines – Used in mining and tunneling to install rock bolts for ground support.
2. Hydraulic Bolting Machines – Use hydraulic pressure to apply precise torque to bolts in heavy-duty applications.
3. Pneumatic (Air) Bolting Machines – Powered by compressed air, often used in assembly lines.
4. Electric Bolting Machines – Use electric motors to tighten bolts, commonly found in automotive and industrial settings.
5. Torque Wrenches (Bolting Tools) – Manual or powered tools that apply controlled torque to fasteners.
Main Functions of a Bolting Machine
A bolting machine is designed to perform several key functions in industrial and construction settings:
1. Bolt Installation – Securely fastens bolts to ensure structural integrity.
2. Bolt Tightening – Applies precise torque to prevent loosening or over-tightening.
3. Bolt Removal – Helps disassemble structures by loosening or extracting bolts.
4. Threading and Cutting – Some machines can create or repair bolt threads.
5. Torque Control – Ensures consistent torque application for safety and durability.
6. Automated Fastening – In manufacturing, bolting machines automate the process for efficiency.
Applications of a Bolting Machine
Bolting machines are used in various industries, including:
1. Mining & Tunneling – Rock bolting machines reinforce underground structures.
2. Construction & Infrastructure – Fasten steel beams, bridges, and structural components.
3. Manufacturing & Assembly Lines – Automate bolting in vehicle and equipment production.
4. Oil & Gas Industry – Secure pipes, flanges, and heavy machinery.
5. Power Plants & Wind Energy – Maintain turbines, generators, and transmission structures.
6. Shipbuilding & Aerospace – Ensure precise fastening in high-stress environments.
