A jack includes a main body (14) with a cavity (18). A lifting cylinder (42) is supported on the main body and is extendable into the cavity. A lock (30, 34) is movably coupled to the main body. A spring (38) is coupled to the lock and biases the lock into the cavity. A cylinder (86) is coupled to the lock and biases the lock out of the cavity against the biasing force of the spring.

A dump trailer support assembly for supporting a belly dump trailer when the belly dump trailer is not coupled to a tractor includes a box for positioning on a support surface beneath a belly dump trailer. A shaft is slidably integrated into the box such that the shaft can be slid upwardly or downwardly in the box. A support is coupled to the shaft for supporting a bottom of the belly dump trailer when the belly dump trailer is not attached to a tractor. Additionally, the support is comprised of a magnetized material to magnetically engage the bottom of the belly dump trailer and inhibit the belly dump trailer from sliding on the support.

A jack stand comprising a base, a stem, and a plurality of interchangeable support tubes. Each support tube of the plurality of interchangeable support tubes is receivable within the base. Once one of the support tubes of the plurality of support tubes is in place within the base, the stem is then receivable within the interchangeable support tube.

A range hood support lift for positioning and supporting the weight of range hoods, exhaust vents, microwave ovens, and the like during the installation process. The range hood support lift includes a support section having a plurality of support arms. A base section includes a plurality of legs and a scissor section separates the plurality of legs. In use, the base section adjusts the height of the support section above the base section and the scissor section adjusts the distance between the plurality of legs.

A trailer system includes a first trailer module, having a plurality of wheels, a loading bed, and a primary loading bed connector for connecting to a loading bed of a further trailer module to form a combined rigid loading bed. The primary loading bed connector is arranged below an upper surface of the loading bed of the first trailer module. A first jack system includes a first jack cradle, which has a jack holder, and a jack accommodated in the jack holder. A primary cradle connector is connected to the primary loading bed connector of the first trailer module and therewith connects the first jack cradle to the first trailer module. The jack holder extends at least partly below the upper surface of the loading bed of the of the first trailer module.
