If you have one of the old Electric Series HercuLocs you will find its service parts here.
I have re-invented the HercuLoc into a much lighter and simpler product. It still has the security and durability of the older models and it is still the best solution for a survey truck.
HercuLoc production is planned to resume in late 2019. These will be manually operated, like the one in the YouTube demo video. The fiberglass covers will be “wrap lids” which follow the contours of the truck bed and cover the plastic bed caps. HercuLocs will only be available for Ford and GM full-sized pickups.
