Gen1 - Maintenance - Lubrication and Calibration
Cable Reeler Lubrication
The cable reeler consists of a multi core cable wrapped around a drum. As the boom
extends, the cable unwinds from the drum. When the boom retracts, the cable winds back
onto the drum.
A cable guide prevents overlying of the cable. This ensures that the cable retracts uniformly onto
the drum. Due to friction between the lays of wire and the layer guide, the cable may sag
or catch during retraction. Therefore, regular lubrication of the cable is required.
A regular inspection of the cable must be performed to ensure proper lubrication. The
inspection interval will be dependent on the operating environment.
To lubricate the cable, fully extend the boom. While retracting the boom spray a
lubricant (RP7, WD40 or equivalent) onto the cable, until the boom is fully retracted.
The cable must be lubricated at all times while the machine is in operation.
System Calibration
As the TSS is a safety device, it's load calibration must be tested every 12 months or
whenever changes have occurred to the hydraulic systems.
The TSS uses boom length and angle transducers plus pressure sensors installed into
the main lifting cylinder and converts the information to a load reading. The variables in
the system can change after a period of time due to a number of different factors. This
may result in a higher or lower load reading; e,g. If the counter balance valves have
been adjusted or sections of the hydraulic system have been replaced, incorrect load
readings can occur. A re calibration will readjust the load reading for any minor changes
in the system.
With each attachment, lift a known weight to ensure the load reading is within ±100 Kg
of the actual weight.
The load calibration must be tested every 12 months. An
incorrect load reading may allow loads to be lifted which
could damage the telehandler or cause injury.
