Power Assisted Levelers
The PAL is a combination of two proven technologies, the power and durability of a mechanical leveler and Serco’s proven, high-performance, hydraulic operation. Unlike mechanicals with a powerful upward bias, the PAL utilizes a hydraulic power-pack assembly and counterbalance assist to produce a slight downward bias. By eliminating pull-chain hold-down mechanisms, adjustable lip extensions and the necessity to walk down decks, the PAL eliminates the physical demands required to operate mechanical levelers.
The PAL also incorporates Serco’s exclusive Reflex™ anti Stump-out system provides fluid free-float motion while also providing a measure of free-fall protection in the event of premature trailer separation.
