Standard Chemset Gun? Or an Easier Option?
Chemical anchoring, particularly into concrete, can be a repetitive and laborious task.
Pre-drilling is one energy-drainer, but the work doesn’t stop there. Then there’s clearing of dust from several—sometimes hundreds of—holes and the injection of chemical anchoring.
For post-rebar installation, chemical anchoring epoxies and the like are commonly inserted with a standard mechanical applicator, like the mechanical Allfasteners, Powers or Ramset Chemset gun.
On jobs with fewer drilled holes, this is fine, but once the amount of bar that needs embedding increases, it becomes a danger to productivity—time and money—and a danger to the worker, through a heightened chance of repetitive strain injury (RSI). Add to this, a mechanical epoxy gun doesn’t always guarantee accuracy of the amount dispensed.
At this point, it is more beneficial to use a battery-powered epoxy applicator, like Ramset’s automatic Chemset gun or the ChemPower gun from Allfasteners, for example.
Ramset’s gun, and similar models by several competitors, allows for easy and fast injection of chemical anchoring with a light finger-touch on the trigger, as opposed to a sustained firm squeeze by an entire hand.
To get even more accuracy and efficiency, Allfasteners ChemPower gun also features a more advanced 9-position dosing dial, this ensures a consistent amount injected with each trigger pull. This can greatly reduce the chance of wastage presented by the other guns’ tendency to allow the user to over or under-fill the hole.
The ChemPower gun also features a more integrated battery shape within the handle, for a less-obstructed view of the task at hand as well as a more balanced feel in the hand. [WATCH VIDEO]
On sites where multiple rebar installations are required, there are instances of workers swapping jobs to keep the fatigue at bay: half an hour of rebar installation—drilling and injecting epoxy—and half on hour of another job, on a rotating basis. When the mechanical gun is replaced by a battery-powered gun, the changeover downtime is eliminated, and one person completes the job, in less time and with more consistency.
And, if the gun chosen is more economically-viable, the contractor is likely to see more return in their bottom line.
So, if a project is being scoped with rebar installation as part of the quote, you may want to consider the motorised battery-powered option as part of getting the job done right. And faster.
