Fifth wheel locking mechanism

In-Cab Air Release improves safety productivity and helps reduce driver injury. The wedge stop rod has been turned in too far not allowing the wedge to travel across far enough to tighten the lock.

1 an operating handle 21 has a first.

Fifth wheel locking mechanism. The locking mechanism of the fifth wheel 4 is in this manner pre-set and ready for re-locking engagement with the king pin of another trailer when the tractor is backed into the latter. The locking mechanism of the fifth wheel is shown in a closed or locked configuration in FIG. 1A that is a configuration where the kingpin of a trailer not shown in FIG.

The locking mechanism which constitutes the improvement to the fifth wheel art is cooperatively mounted to the fifth wheel assembly 11. As may be seen in FIG. 1 an operating handle 21 has a first.

The fifth wheel is equipped with a locking mechanism including a jaw slidably connected to the top plate and slidable between a closed position where the jaw blocks passage of a kingpin out of the throat of the fifth wheel and an open position where a kingpin may pass into and out of the throat of the fifth wheel. The locking mechanism which constitutes the improvement to the fifth wheel art is cooperatively mounted to the fifth wheel assembly 11. As may be seen in FIG.

1 an operating handle 21 has a first end 22 pivotally mounted to fifth wheel assembly 11 proximal throat 14 at pivot axis 23 by means of a conventional bolt spacers and fasteners. The locking mechanism which constitutes the improvement to the fifth wheel art is cooperatively mounted to the fifth wheel assembly 11. As may be seen in FIG.

1 an operating handle 21 has a first end 22 pivotally mounted to fifth wheel assembly 11 proximal throat 14 at pivot axis 23 by means of a conventional bolt spacers and fasteners. A fifth wheel for an over the road tractor having an operating rod for the locking mechanism which requires only longitudinal and rotary motion thus facilitating operation thereof in the space between tractor frame and trailer and permitting that space to be reduced in that no vertical lifting motion is imparted to the operating rod. No contact no couple.

Specifically designed to reduce miscoupling our patented TechLock systems jaw height sensor will not allow the fifth wheel to close if the kingpin enters at the incorrect height or position. Fifth - Wheel Coupling. Fifth Wheel Couplings provide the critical link and connection between a trailer semi-trailer and the towing vehicle.

Fifth wheel couplings are a safety critical component. We understand that fifth wheel flexibility is vital for your vehicles performance so whether you require a fixed sliding or double oscillating. Hardened lubricants that bind the locking mechanism.

You should never attempt to couple a fifth wheel that has snow ice or debris in the throat area. Improper coupling can occur possibly resulting in serious injury or death. 2 3 Lubricate top plate and locking mechanism.

After application of fresh lubricant open and close the. The fifth wheel is equipped with a locking mechanism including a jaw slidably connected to the top plate and slidable between a closed position where the jaw blocks passage of a kingpin out of the. A schematic diagram of the locking mechanism in a typical fifth wheel.

A Locked with spring closed and b set for coupling. A schematic diagram of the spring loaded hook arrangement which prevents the operating handle from opening. In one feature of the present invention the bottom half of the fifth wheel includes a universal locking means having a horizontally movable locking structure for engaging the neck portion of the king pin such locking structure being capable of providing at least two vertically offset locking collar portions for locking at least two different fifth wheel combinations in which the neck portion of the king pin can.

Fifth wheel coupling is a key component of heavy duty semi-trailer tractor providing the link between the semi-trailer and the towing tractor. Proper functioning of the locking mechanism. Following these simple steps will ensure long life to your fifth wheel.

The wedge stop rod has been turned in too far not allowing the wedge to travel across far enough to tighten the lock. Or the jaw and wedge serrations have worn beyond tolerances. The safety locking mechanism allows you to hook to your fifth wheel with confidence.

We designed this to aide in the safety of the unit and driver. With the fifth wheel locked in place the slide lock pin will securely latch and the clevis pin locks into place for added security. Environmentally friendly and economical.

The LubeTronic 5Point was developed for fifth-wheel couplings without top plate liners. This is a lubrication system integrated into a fifth-wheel coupling. Wheel from the lock handle.

Striking the wedge stop rod will release the wedge in the lock mechanism. If the wedge stop rod is turned in too far it will cause binding on the secondary lock and the inability to open the fifth wheel. If the fifth wheel still will not open more severe procedures may need to be taken.

Air Release option allows in-cab air release of the fifth wheel locking mechanism. With just a simple pull of a dash-mounted air switch a pneumatic cylinder on the fifth wheel will effortlessly open the locking mechanism. In-Cab Air Release improves safety productivity and helps reduce driver injury.

Set the tractor parking brake and pull the fifth wheel release valve until locking mechanism opens and locks in place. Release the pull valve. Release the tractor parking brake.

A proper couple open the fifth wheel inspect for damaged components and repeat the coupling sequence. Locking jaw and wedge must be fully across the throat of the fifth wheel Kingpin Wedge Fifth wheel throat No gap between trailer bottom and fifth wheel 1 Skirt Pull handle Gap between pull handle and skirt of wheel less than 1.
