Product Description:The lubrication unit starts to warm up when the jacking system is powered on and a control signal is sent to each leg lubrication unit. The lower limit of the oil tank of the lubricating power unit can be automatically checked through the lifting console, or the indicator light can be used to confirm whether there is enough lubricating oil at the side of the lubricating unit, so as to ensure uninterrupted lubrication during lifting and lowering operation. Each GPP has a total of 30L lubricating oil tank, so a GPP will automatically lubricate a rack with a length of 100-265m.
