Benefits of technology

[0004]It is an object of the present invention to provide for worker safety for drivers and unloaders of flatbed trucks.
[0005]It is also an object of the present to prevent loads from shifting while being transported by and unloaded from flatbed trucks.
[0016]Preferably, each dunnage timber of each pair of dunnage timbers is shorter than the width of the load and is attached to one respective chuck and lock unit at a distal outer end. The timbers are adjacent to each other and staggered so that the chuck and lock units are not constrained to a fixed spacing, thereby allowing a spread between the vertically extendable braces at each end of the pair of timbers to be adjusted, by changing the overlap of the dunnage timbers in each pair, according to the size of the load to be contained and supported.

Problems solved by technology

However, the vertical braces are still in place preventing load from shifting sideways and causing an accident.

Embodiment Construction

[0035]In the description that follows, dunnage is assumed to be timber with a 4 by 4 crossection or using two 2 by 4 pieces adjacent to each other as is common in the USA. Dimensions to accommodate these common timber sizes are presented. In other jurisdictions, similarly sized timber of common metric dimensions would be used as dunnage and as stakes. Therefore the extendable brace and the chuck and lock units for those regions may deviate slightly from the dimensions discussed here.

[0036]The problems of conventional load removal from flat bed platform trucks is shown in prior art drawing FIGS. 1 and 2. For example, prior art FIG. 1 shows a flatbed truck 1 with a load 2 clamped down by two straps 3 as is common recommended practice. Prior art FIG. 2 shows an accident in process as the straps 3 are detached from one side and load 2 is shifting and tumbling off the side of truck 1.

[0037]In contrast to the dangers and problems associated with the prior art depicted in FIGS. 1 and 2, th...

Abstract

A chuck and lock system prevents the load on a flatbed truck from shifting at the destination during offloading. The system includes one or more extendable brace units or vertical stakes and a movable chuck and lock, which operates as a socket locking each extendable brace in place. The chuck and lock unit is attached to dunnage underneath the load. The units can be spaced on either side of the load where needed. The load is held on each side between the vertical braces adjacent to the load and which are adjusted for the height of the load. Straps are supported by the extendable braces and go over the load. At the destination, prior to unloading, all straps or lashings are removed or loosened. The vertical braces prevent the load from shifting sideways and causing an accident. The load is offloaded by a load lift.

Description

FIELD OF THE INVENTION[0001]The present invention relates to worker safety and for preventing loads from shifting while being transported by flatbed trucks.BACKGROUND OF THE INVENTION[0002]There are many guidelines and techniques for preventing loads from shifting while being transported by flatbed trucks. If they are followed, these instructions do prevent accidents by showing the proper use of tie-down lashings, ideal location of load on a truck bed, and the use of dunnage to clamp the load more effectively. However, there is little guidance and apparatus available to prevent the load from shifting and possibly falling from the vehicle during offloading at a destination. Such accidents can cause serious injury and even death.[0003]In this invention several terms, such as “dunnage”, “dunnage timbers”“braces” and “stakes”, which may be common in the trucking industry, will be used. Dunnage refers to any material which is not part of an actual load to be transported placed under or a...
