Selecting the Correct Size Hammer

Mounting hydraulic hammers on a variety of different sizes and equipment types has become common. Choosing a model of the correct size for your machine will increase the life span, production, and your profitability with the hammer. As you consider your hammer selection, consider these recommendations to greatly increase the chance of a successful experience.

First, consider the hammers recommended carrier weight range. This information should be readily available in the product specifications provided by the hammer manufacturer. This ensures the hammer was created for use on a specific size of carrier. AlliedPBS models are named by the size of machine that they fit. For example, an AlliedPBS AB2230 fits an excavator weighing between 22 and 30 metric tons. Choosing a hammer that is too small for your machine can lead to failures of the hammer’s tool steel, mounting brackets, and internal parts from stresses generated by the host machine. Sourcing a hammer that is larger than recommended for your carrier can lead to unstable operation or equipment tipping when the boom and stick are at full extension or when operating over the side of your tracks.

Second, consider the hydraulic input requirements of the hammer and compare those needs to the output specification of the hydraulic circuit on your machine that will power the hammer. Reference previous AlliedPBS Tech Tip “Hydraulic Flow and Pressure Adjustments”.

Third, consider your options for machine sharing if applicable. If the hammer will be used on multiple machines in your fleet, make sure your choice of mounting bracket accommodates all machines in question. When utilizing a pin grabbing quick coupler, the hammer mounting bracket should utilize appropriately sized pins with the correct pin spacing to match the range of the coupler being used.

Finally, investigate the after sales support, parts availability, and technical knowledge of the hammer supplier to guarantee that you can get quality assistance when you need help. Your new hammer should be installed and adjusted by a competent person, familiar with hydraulic attachment installation.
