6.0 CONNECTIONS TO POWER TONG
The Backup is designed to connect via hydraulic hoses to a four way, three position valve located on a
Power Tong so that the it may be opened or closed as required and pressured up to hold the tubular in
place.
WARNING: It is very important to ensure hoses are inspected on a regular basis for wear and
damage. If replacing hoses, ensure hose pressure rating matches the maximum
system pressure intended to be used with the Backup.
Figure 6.01 shows a typical connection to a Power Tong. It should be noted the connection orientation
to the Backup’s pressure relief valve is typical and is recommended as shown. Depending on the exact
operation of the four way, three position valve for opening and closing the Backup, if required, the
hoses can be reversed on the connection to the valve bank.
As the Backup may be installed on a variety of Tongs (both Universe and other competitors), it is
important that the maximum torque rating of the Backup Unit (see section 2.1) is never exceeded.
WARNING: Exceeding the maximum torque rating of the Backup Unit may result in damage to
the Unit or possible injury to the operator.
