Wear-resistant spare parts installed in SANDVIK propulsion beam guides, using Dupont PU as raw material, and made through special formula injection process. The surface is smooth and of stable quality
Installation instructions (from Sandvik Maintenance Manual)
The beam of the TF 500 is made of an aluminum profile with the sliding surfaces faced with stainless steel strips.The carriers of the rock drill, hose reel, and intermediate centraliser move along the feed beam on similar slide pieces. Each slide piece is fastened to the carrier with three screws and nuts through the frame strip. The screws lock the slide piece lengthwise. The form of the slide pieces and their supports function as lateral locking.The slide pieces normally require no adjustments when replaced, as the pieces are located to correct clearances at the beam centre line with the aid of locating shoulders on the carriers and the frame strips.If the slide pieces are so worn that the clearance is more than 3 mm, the clearance can be adjusted to the specified valuewith the slotted holes in the carriages. After adjustment, the screws are tightened to 120 Nm.
A = max. 1,5mm
B = 0 (clearance)
