Step #2 Liners assembly
High-speed pre-tightening and precise tightening on the final torque
Optimize tightening speed and preserve impact wrench performance
To expedite the tightening process during mill lining operations, we propose a two-step approach. Firstly, we suggest pre-tightening with a high-speed impact wrench, provided it is approved by the equipment manufacturer.
Then, for achieving the final torque, the use of an electric tool is recommended. It is crucial to select the appropriate power rating for the impact wrench to prevent over-torque tightening of the bolted joints. Additionally, to prolong the lifespan of the impact wrench, it is advisable to limit trigger usage to no more than 5-7 seconds after completing the bolt run-down.
By implementing this pre-assembly step, you can attain the utmost speed in pre-installation (tightening) of the nuts on the lining bolts. This optimized approach not only streamlines the tightening process but also preserves the performance and longevity of the impact wrench.

Enhance operator comfort and efficiency with tool balancers
The substantial weight of an impact wrench often requires operators to bear its load for extended periods. However, employing balancers designed for heavy tools can significantly alleviate this strain and boost productivity. Lightweight balancers equipped with conical drums provide optimal tension support and effectively counterbalance the weight of the tool. Our WP 20 balancer features an aluminum body, while the WP 30 model is crafted from durable, wear-resistant aluminum.
By utilizing these innovative tool balancers, operators can experience improved comfort during prolonged tool usage, leading to increased speed and efficiency in their work.
Note: The revised version maintains the core message of the original text while enhancing its clarity and flow. It highlights the benefits of using balancers for impact wrenches, emphasizes their lightweight nature and conical drum support, and provides specific details about the WP 20 and WP 30 models.
