The invention relates to a vehicle (1), in particular a truck-mounted concrete pump, having a pivotable turntable (3), arranged on a frame (2), with a boom (4) constructed thereon, and a frame outrigger (5) which has carriers (6, 6a) that are retractable into the vehicle profile and/or extendable out of the vehicle profile, wherein the carriers (6, 6a) are each guided on an extension portion (7, 7a) fixed to the vehicle and form a telescope (8, 8a) therewith, wherein the extension portions (7, 7a) fixed to the vehicle are arranged behind a cab (9) in the direction of travel, wherein a folding part (11, 11a) connected via a joint (10, 10a) is arranged in each case at a free end of the carriers (6, 6a), wherein a support leg (12, 12a) is arranged on each folding part (11, 11 a), wherein the joint (10, 10a) is arranged outside the respective extension portion (7, 7a) in the retracted transport position of the carriers (6, 6a), such that the folding part (11, 11a) is foldable laterally into the vehicle profile in a transport folded position, wherein the folding part (11, 11a) is foldable forward in the direction of the cab (9) in the transport folded position.

Vessel transfer systems are provide herein. The systems include bogies, including a pivoting bogie and a rack and pinion bogie, as well as associated cradles, carriages, and power and control units. The pivoting bogie includes a first side frame, a second side frame, at least one wheel coupled with each of the first and second side frames, and a lift member coupled with each of the first and second side frames. The lift member is pivotably coupled to the first side frame. The rack and pinion bogie includes a frame and pinion gears coupled with the frame. The pinion gears can be selectively coupled with a gear rack, such as at a shipyard. Also provided herein are methods of use of one or both of the bogies and associated equipment, such as for moving vessels within a shipyard.

A trailer restraining device comprising a portable frame having mounted thereto a tail hook and a king pin receiver that includes at least one of a receiver hydraulic cylinder, a receiver pneumatic cylinder, a receiver electric actuator, and a receiver winch.

A trailer jacking system includes a trailer that has a pair of axles, a first lateral side and a second lateral side. A pair of bars is provided and each of the bars is coupled between each of the axles. A jack is selectively positioned beneath the bars for jacking the trailer. Each of the bars is oriented collinear with an associated one of the first and second lateral sides. In this way each of the bars facilitates the trailer to be leveled between the first and second lateral sides when the trailer is jacked. A plurality of u-bolts is provided and each of the u-bolts bolts is coupled between the bars and an associated one of the axles to retain the bars on the axles.

A jack assembly is shown and describe. The jack assembly may include a first tube having first and second end portions and a central portion between the first and second end portions, and a second tube positioned within the first tube and movable with respect to the first tube. The jack assembly may also include an expanded portion on the first tube, the expanded portion having a larger inner diameter than an inner diameter of the central portion, and a bushing attached to the expanded portion, where the bushing generally prevents contact between the first and second tubes.

An ATV jack may include an engagement member and a leg which pivots which respect to the engagement member a limited amount to enable the jack to lift and hold an ATV. The leg may telescope to allow the jack to be used at a wide variety of heights. The jack may also be used as part of a system with at least one mounting bracket to allow a tire of an ATV to be lifted and retained or replaced.

An integrated anti-tip mechanism is provided for aiding prevention of an electronics rack from tipping. The anti-tip mechanism comprises a long portion with a first end and a second end, the first end coupled to a base of the electronics rack and the second end coupled to a first end of a short portion. The first end of the short portion is coupled to the second end of the long portion and a second end of the short portion further coupled to a caster. When deployed, the caster rolls in a same direction as a set of casters beneath the electronics rack. The caster is a predetermined distance off the floor such that the weight of the electronics rack is carried by the set of casters beneath the electronics rack but contact the floor if the electronics rack tips thereby preventing the electronics rack from tipping past a predetermined angle.

A top link for a tractor front counterweight support linkage. The link is a fixed length elongate body having at a first end a pivoting connection with a chassis of the tractor and at a second end a slot to slidably receive an attachment bolt connectable to a tractor front counterweight. The link further includes a mechanism to selectively permit or prevent sliding movement of an attachment bolt received in the slot.

A system and method to level a vehicle. The method utilizes a reference current draw unique for each individual actuator that is measured and saved at measured temperature and actuator actuating duration times. The reference current draws are adjusted by a fixed predetermined compensation increment and by a variable predetermined time and temperature increment. During operating function steps, actual extend and retract current draws are measured, which may be at another temperature and duration time. The adjusted reference current draws are compared to the actual extend and retract current draws to determine when desired conditions such as ground contact or fully retracted condition are achieved.
