Abstract: Disclosed herein are hand trucks for installing and removing water heaters. The disclosed water heater hand trucks enable a single person to lift the water heater onto a platform and to keep the water heater above the water heater pan during installation and removal. The disclosed hand trucks generally include a main platform and a wheel frame. A water heater is strapped to the main platform which has curved legs at the bottom with rubber landing feet. This design is used to keep the water heater above a water heater pan while lifting the water heater into position. This avoids crushing the pan with the water heater. The handles at the upper section of the main platform have adjustable positions. These handles can be opened up to an outward position to provide leverage, which can be advantageous when access to the platform is limited from a frontal approach.

Abstract: A convertible cart allows for carriage of many items of different shapes in a position that provides a base with front and back walls, along with structural rods preventing items from sliding out of either side. A two-level tiered configuration may be best suited for carriage of larger, fragile items which cannot be stacked atop each other, or simply for organization of different large items. For the largest loads, a flat base arrangement maximizes both vertical space and available base area while providing the handlebar at an appropriate position for pushing or pulling. When transportation of items is complete, a flat configuration minimizes necessary storage space for the apparatus. These different arrangements are made possible through the employment of several rigid and telescoping members, which enable both custom handlebar arrangement and secure, intuitive adjustment between configurations. Swiveling wheels improve the mobility of the apparatus during use.

The frame, transport propulsion members and handle structure are cooperatively dimensioned and configured for movement of the cart over ground surfaces of topographic terrains and for partially and fully submerged movement over water-covered surfaces of hydrographic terrains.

Abstract: The unloading facilitator of the present invention includes a shaped unloading facilitator and grab-strap. The unloading facilitator is designed to fit into utility, farm and garden dump wagons and is shaped to conform to the body of the utility, farm and garden dump wagons and to overlap the top edge of the dump wagons.

The unloading facilitator is used for removing all the material from the dump wagons when the dump wagons are in the dumping position. When material-loaded dump wagons are placed in the dumping position, most of the material remains in the dump wagons because the material stops sliding out as soon as the material contacts the ground. Presently all material would have be removed manually with a shovel, rake or garden hoe.
