Liftgate For DeliveryLiftgate For Delivery - The liftgate service is offered by the shipper to provide delivery off the truck to your curbside. The carrier will lower the packaged skid off the delivery truck to the ground with a forklift-type device. From there, it is ready for unpacking and moving in individual pieces to the assembly site.

As these kits are quite heavy, if you do not have a loading dock or a forklift available, the liftgate is a recommended option to speed up delivery. The pallet can then be opened at your curbside and each piece is lightweight enough so that they can be individually moved to the assembly site. This usually only takes about 30 minutes or less depending on how much help you have.
