A support assembly comprises a bracket, a blocking member, and a spring. The blocking member is adapted to slidingly move within a through opening of a support member. The blocking member is adapted to be selectively moved from a supporting position to a non-supporting position. The spring is adapted to bias the blocking member towards the non-supporting position. In certain embodiments, the bracket is adapted to retain the blocking member at least partially within the through opening when the bracket is mounted to a hoist. In certain embodiments, the blocking member comprises a handle comprising a pin axially aligned within a compression spring and the bracket comprises a notch adapted to receive the handle.

A jack, comprising: a top plate adapted to contact a load; a base plate positioned below the top plate; at least one actuator coupled perpendicularly between the base plate and the top plate; wherein the at least one actuator is operable to move the top plate between a lowered position and a raised position to thereby lower and raise the load; and, at least one locking assembly adapted to lock the top plate in the raised position.

The hoist comprises a base, first and second lower arms, first and second upper arms, and one or more blocking members. The first and second lower arms are pivotally coupled to the base. The first lower arm is pivotally coupled to the first upper arm. The second lower arm is pivotally coupled to the second upper arm. The lower arms and upper arms are adapted to move between an unraised condition to a raised condition. Each of the blocking members is adapted to move between a supporting position and a non-supporting position. Each blocking member, when in the supporting position, prevents the lower arms and upper arms from moving from the raised condition to the unraised condition.

A floor jack locking assembly is presented. The locking assembly may include a locking pin used to mechanically lock out the jack at a specified lift height. The locking assembly may avoid the hydraulic lift cylinder being the only stabilizing component of the jack when supporting a significant load. The locking pin may be coupled to lifting link arms, avoiding the need to have the locking pin inserted into or through the lifting arm of the jack.

A hydraulic floor jack with an integrated support is disclosed. The floor jack can be used with the floor jack oriented in any orientation relative to the orientation of a vehicle to be raised. The support remains suspended above the ground allowing the floor jack to roll along the ground while the vehicle is being raised. The support is then biased firmly on the ground, under weight of the vehicle, while the vehicle is suspended. A method of use of a hydraulic floor jack is also disclosed.
