The baton stand is a training device that is configured for use with a baton that is used in the relay race events of a track and field competition. The baton stand is a container within which a baton can be placed or removed as a runner passes by the baton stand. The baton stand is adjustable such that the baton stand will simulate the angle and height the baton should be in during the acceptance or hand off of the baton. To use the baton stand, a runner runs past the baton stand and, depending on the objective of the training exercise, will place the baton into or remove the baton from the baton stand. The baton stand comprises a telescopic stanchion, a stand, a basket, and a locking hinge. The stand attaches to the telescopic stanchion. The locking hinge attaches the basket to the telescopic stanchion.

A system for moving a receptacle. The system includes: a coupling wall; an internal carriage provided substantially adjacent the coupling wall, the internal carriage being movable along the coupling wall along a predetermined path; an external carriage provided substantially adjacent the coupling wall and substantially in register with the internal carriage with the coupling wall extending between the internal and external carriages, the external carriage being movable along the coupling wall, the external carriage including a receptacle attachment for securing the receptacle thereto; and a carriage actuator operatively coupled to the internal carriage for moving the internal carriage along the predetermined path. The internal and external carriages are magnetically coupled to each other across the coupling wall so that when the internal carriage is moved along the predetermined path, the external carriage follows the internal carriage and remains substantially in register therewith.

A rig skidding method involving raising a rig on jacks, positioning skid tracks comprising low friction plastic underneath the rig, lowering the rig, and skidding the rig along the skid tracks to a new site for rig operations. At the new site, the process is reversed to leave the rig on the ground at the new location.

An apparatus including a lifting jack having a beam, and a base having a first section with a first opening configured to receive the beam. The base may further include one or more foundation plates connected to the first section in a manner so that each of the one or more foundation plates can be rotated with respect to the first section. The one or more foundation plates may include a first, second, third, and fourth foundation plates. The first foundation plate and the second foundation plate may be about the same size and shape. The third foundation plate and the fourth foundation plate may be about the same size and shape. The first foundation plate and the third foundation plate may be substantially different in size. Each of the one or more foundation plates may have a bottom surface, from which protrude a plurality of protrusions.

Embodiments described herein may include at least one pole including a plurality of projections disposed at incremental heights along the pole, an object, a first pulley positioned on a first side of the object, and a second pulley positioned on the second side of the object.

A lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot, a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot, and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.
