A Hydraulic lifter can allow you to raise up your wood fired oven so you can easily slide it onto the stand or your bench top. You will need to slide it from the box to the platform, raise it to a suitable height, and then slide it across. You will still need four people to manoeuvre the oven but they will not need to lift the full weight, significantly reducing the strain.
Hydraulic lifters have varying weight limits, please make sure you choose the correct lifter for your oven.
