Frequently Asked Questions
The BTL Series ensures precise and uniform tensioning, reducing the risk of uneven load distribution that can lead to bolt failures or joint leakage in critical industrial operations.
Yes, the compact and lightweight design of the BTL Series allows for easy use in confined spaces, making it ideal for offshore platforms and other tight environments.
The BTL Series includes an overstroke alarm that alerts operators when the tool is being over-extended, protecting both the equipment and operators from potential damage.
The automatic piston-return resets the tool after each cycle, allowing for faster tensioning and reducing downtime, especially useful in large-scale projects.
Yes, the BTL Series is versatile and supports a wide range of bolt sizes, making it suitable for industries such as wind energy, oil and gas, and power generation.
