A tensioning system is attached to the cable restraint line. The tensioning system allows the flaps to distort as the loading truck body engages the hopper entrance. Once the truck exits the hopper entrance the hopper flap suspension system causes the flaps to spring back to their original shape. The suspension system may include a torsion spring biasing the flaps into a vertical position. The tensioning system may include a tension adjuster. Using this system the flaps are not torn and hold the asphalt in place as the loading trucks dump asphalt into the hopper. | 10-22-2009 |
| 20090263194 | Feeder hopper, a method for locking the walls of a feeder hopper and a locking means - Feeder hopper for a movable mineral material processing device, whose walls are arranged to be turned upward to a working position, and which are locked into said working position. To lock the walls, there is at least one locking means in connection with them, said locking means containing at least a locking member and transfer means. According to the method the locking member is transferred to the locking position with the transfer means. | 10-22-2009 |
| 20120257927 | SEALANT DISPENSER AND SPREADER - The present invention is directed to a combination sealant dispensing and spreading apparatus for selectively dispending and spreading sealant upon a paved surface, the apparatus comprising a moveable frame having a lower support, a sealant tank the lower support operably connected to a V-shaped spreading means for spreading sealant from the tank upon the paved surface. | 10-11-2012 |
| 20160040368 | HOPPER ASSEMBLY FOR PAVING MACHINES - A paving machine includes a hopper assembly movable between a lowered position and a raised position and a conveyor frame. A first hopper is pivotally connected to the conveyor frame at a first hopper axis and a second hopper is pivotally connected to the conveyor frame at a second hopper axis. A first apron is connected to the first hopper about a first apron axis. A second apron is connected to the second hopper about a second apron axis. The first apron axis and the second apron axis are respectively perpendicular to the first and second hopper axis. A central apron is pivotally connected relative to the conveyor frame about a central axis that is inline to the first and second apron axis in the lowered position. The first and the second apron axis are planarly translated to the central axis from the lowered to the raised position. | 02-11-2016 |
| 20160060823 | CONSTRUCTION MACHINE WITH OFFSET HOPPER REAR WALLS - A construction machine according to the disclosure comprises a material hopper for receiving bulk material. The material hopper comprises a first sub-hopper that is pivotable about a first axis and a second sub-hopper that is pivotable about a second axis, wherein the first and second axes extend parallel to each other. The first and second sub-hoppers each comprise a rear wall, and the rear walls are shifted with respect to each other in a direction parallel to the axes, whereby a collision of the rear walls is prevented when pivoting the first and/or the second sub-hopper. | 03-03-2016 |
| 20160108585 | HOPPER BAFFLE ASSEMBLY FOR ASPHALT PAVING MACHINE - An asphalt receiving hopper for an asphalt paving machine includes a left sidewall, a right sidewall, a front wall and a pair of baffle panels.
