| 414444000 | TILTING VEHICLE-TYPE HANDLER (I.E., PORTABLE GRAPPLE) | 9 |
| 20090285659 | COMPACT SYSTEM FOR LIFTING AND MOVING A PRESSURIZED TANK - A hoist with a cradle for coupling with a pressurized tank. A primary means of restraining the tank on the cradle is provided along with a backup means should the primary means fail for any reason. A linear actuator assembly raises the cradle up to 27 inches from the floor surface. An onboard battery with an integrated battery charger provides power to the linear actuator. A compact base with swivel casters allows a raised tank to be safely lifted and transported by a single operator. The compact size of the hoist allows it to operate in confined spaces. | 11-19-2009 |
| 20110052356 | Multidimensional Lifting Handtruck - According to one embodiment, a handtruck is provided. The handtruck may have wheels. Legs, approximately parallel to the ground, are coupled to the wheels. The legs may also be moved within a plane that is approximately parallel to the ground. A back is coupled approximately perpendicular to the legs. A payload coupler is coupled to the back and allows the coupling of a payload to the handtruck. | 03-03-2011 |
| 20120045304 | HAND TRUCK - A hand truck has a frame, at least one wheel which is mounted to the frame at a lower part of the frame, at least one holding magnet for holding an object which, at least in part, has a magnetic or magnetisable outer surface, and a release mechanism mounted to the frame. The release mechanism has a release member movably mounted to the frame of the hand truck. The at least one holding magnet is attached to the release member. The release member is mounted to the frame of the hand truck such that the at least one holding magnet can be pulled backwards while the object rests against the frame, thereby providing a damage free release of the object. | 02-23-2012 |
| 20120141238 | BARREL TRUCK - A barrel truck comprising a handle, a wheeled support coupled to the handle, wheels of the support being spaced apart on the support to receive a barrel to be lifted therebetween, the handle being fixedly coupled to the wheeled support, a member coupled to the wheeled support for engaging with a rib of the barrel, and the member adapted to have a force applied thereto to exert an upward force on the rib of the barrel to lift the barrel off the ground in order to move the barrel on the wheeled support, the force being applied to the member by pivoting the handle with a vertical motion. | 06-07-2012 |
| 414448000 | With band-type engager | 1 |
| 20150063961 | HAND TRUCK MOUNTING STRUCTURE - A mounting structure for a hand truck is described. Embodiments of the present invention include a mounting structure adapted to be secured to a hand truck. Generally, the mounting structure can be implemented to secure a strapping device to the hand truck. The mounting structure can generally include a body, a first member, a second member, and a spring. Typically, the first member can be slidably coupled to the body and the second member can be fixedly coupled to the body. The first member and the second member can include concave faces to interface with a frame of the hand truck. The mounting structure can couple to the hand truck in a variety of locations to ensure that the strapping device is optimally positioned to secure a particular load. | 03-05-2015 |
| 414453000 | Single movable jaw gripper | 1 |
| 414454000 | With operating means | 1 |
| 20100021275 | DUAL CYLINDER CART - A hand cart useful in transporting one or two cylinders for example of the type used to contain compressed gasses. A preferred embodiment has at least one pair of cylinder-grasping arms rotatable apart to a spread open position for loading and unloading cylinders, and rotatable together to a closed position for holding cylinders. A fold-out prop helps support the cart and tanks so that vertical force is not needed to move the cart forward or backward, and stabilizes the cart while stationary. | 01-28-2010 |
| 414457000 | Rigid-type grapple engaging means (e.g., hooks, etc.) | 3 |
| 20100124476 | CYLINDER CART HAVING A RETENTION HOOK - A cart for carrying a cylinder containing a liquid or gas is disclosed, the cylinder having an anchor location, the cart including a frame including a body and a handle, wheels coupled to the frame for carrying the frame and the cylinder, a hook capable of engaging the anchor location of the cylinder to capture and retain the cylinder on the frame, an automatic actuator configured to move the hook into and out of engagement with the anchor location, and first and second safety switches that are configured to be engaged respectively by left and right hands of a user, the safety switches disabling the actuator if not engaged by both hands of the user. | 05-20-2010 |
| 20110274526 | DOCK DOLLY - A dolly for supporting an end of a dock and translationally shifting the dock, the dock having side frame members and being supported proximate a first end by a plurality of wheels, includes first and second engaging members disposable adjacent a respective dock side, the first and second engaging members being adapted to selectively engage a respective dock side frame member. | 11-10-2011 |
| 20130094928 | BARREL TRUCK - A barrel truck has a handle structure; a wheeled support, the wheels spaced apart such that the wheels can slide under a barrel when the barrel is pivoted; a cradling member pivotally coupled to the support for engaging the perimeter of the barrel but not extending past the center line of the barrel; and an upright structure having a gripping mechanism for gripping the top of the barrel adapted to have a force applied thereto to exert an upward force on the barrel to pivot the barrel off the ground causing the wheeled support to move forward and pivot with respect to the cradling member, allowing the wheels on the wheeled support to move underneath the barrel, with further force on the handle structure lifting the barrel off the ground balanced over the wheels. | 04-18-2013 |
