SFPL - General - Maintenance

The components of the SFPL require periodic checks and maintenance to be performed to ensure it remains in working order.

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.

Sensor Calibration

As the SFPL is a safety device it's sensor calibration must be tested every 12 months or whenever changes have occurred to the man platform systems. The SFPL uses boom length and angle transducers to determine the current location of the boom. The variables in the system can change after a period of time due to a number of different factors, this may result in an incorrect boom location reading. A re calibration will readjust the location reading for any minor changes in the systems. If re calibration is required follow the instructions for the sensor calibrations 

The sensor calibrations must be tested every 12 months. An incorrect boom location reading may allow the boom to enter an unsafe location which could damage the man platform or cause injury.
