Arch tube spreaders of type RMR V25 and RMR V29 are used to stabilise and connect V25 and V29 roof support arches in mining applications.
The pipe spreaders consist of the following elements:
- connecting tube (connector)
- holder
- U bar or hook bolts
The connector, which is the main spacing element, is manufactured in the size ø42.4 x 3.2 mm, whilst its length depends on the arch spacing. Both connector ends are appropriately bevelled and formed into oval shape to achieve better adherence to the holder. Assembly holes of ø22 mm make it possible to join the connector with V25 section. The holder is made of a flat bar of 8 x 40. The middle part of the holder tightly adheres to the arch section and the arms fit the connector. U bar and hook bolts are made of plain bar with M20 thread.
