Simex say that it is launching a number of new hydraulic attachment units that will further boost its product range, with its 74 models across 19 product lines. The company is looking to introduce new versions of its wheel saw line-up, units which are designed to cope with tough conditions in mini-trenching applications. The current models in the RW and T wheel saw ranges feature working widths from 25-250mm and cutting depths from 200-800mm. However new models being launched will offer performance gains across a range of duty cycles. As with the existing wheel saws, the new variants can deliver clean and precise trenches that require minimum maintenance.
