My grocery uses an LPG forklift on the loading dock to unload pallets from 18 wheelers and we use another in the store basement to lower the pallets from the loading dock into the basement and also to rotate pallet-based stock between the store and the facility. It is preferable and safer not to be driving an LPG forklift into the facility, except into the isolated stock area where the pallet flow racks are. In hydroponics, which is at the far end of the facility, the stewards have always depended on a LPG forklift to "bring them" their IBC containers full of liquid fertilizer rather than try to use a manual pallet jack to drag it all the way over from the grocery basement. Now we have a battery-powered (LiFePO4) pallet jack that anyone can use. It turns on a dime and easily lasts all day. And best, the electric brake is smooth and effective. So, if you move a lot of heavy stuff, consider something like the EKKO EP20JLI. I would avoid a regular Lithium battery jack just because a fire is never worth the risk. There are also plenty of other brands out there that have less capacity and cost a lot less. The only complaint has been that the manual jacks are WAY quicker...the electric crawls, but I think that's good because it gives them more thinking and stopping time. It's definitely safer than barreling through on a manual jack with almost 3000 pounds of liquid fertilizer.
