Patent number: 7762617Abstract: A trailer includes a chassis and a body connected to the chassis. The body includes an open-top cargo-retaining space adapted to carry a bulk commodity payload. An axle subassembly is connected to the chassis and includes at least one set of left and right wheel and tire assemblies to rollably support the chassis. A landing gear assembly is connected to one or both of the chassis and body and includes legs that are selectively deployed to support a forward end of the trailer. A kingpin is located at the forward end of the trailer and is adapted for connection to a fifth-wheel of an associated vehicle used to pull the trailer. The body includes left and right bottom rails and left and right top rails spaced vertically above the left and right bottom rails, respectively. A horizontal floor extends between the left and right bottom rails. The floor includes a plurality of abutted one-piece extruded panels that each extend horizontally between and contact the left bottom rail and the right bottom rail.Type: GrantFiled: June 18, 2008Date of Patent: July 27, 2010Assignee: East Manufacturing CorporationInventor: Howard D.

Patent number: 7461865Abstract: A hanger assembly comprises a pair of hangers; a pair of trailer attachment plates, each attachment plate attached to one of the pair of hangers; and a transverse support member having a first end attached to one of the pair of hangers and a second end attached to the remaining hanger of the pair of hangers. The hanger assembly is made of aluminum and provides a lightweight, high strength hanger assembly for a trailer that cuts down on the weight of the trailer without diminishing the strength as compared to conventional trailers, and that is compatible with a conventional air ride suspension system and retrofittable on existing aluminum trailers in a bolt-on configuration.Type: GrantFiled: November 30, 2006Date of Patent: December 9, 2008Assignee: East Manufacturing CorporationInventor: James H.

Patent number: 7458758Abstract: A hook hanger for a cargo trailer includes a body. The body includes: (i) a mounting bracket conforming in shape to and slidably engageable with an associated sliding track of an associated cargo trailer; (ii) a hook anchor connected to the mounting bracket; and, (iii) a wall that cooperates with the hook anchor to define a channel including an opening in a side of the body. The wall limits vertical movement of a hook connected to the hook anchor to prevent inadvertent disengagement by vertical movement. The hook is disengageable from the hook anchor only by sliding movement transverse to vertical and through the channel opening. The channel opening is selectively blocked by a movable leg member connected to the body.Type: GrantFiled: January 8, 2007Date of Patent: December 2, 2008Assignee: East Manufacturing CorporationInventor: James H.

Patent number: 7390053Abstract: A load-carrying floor for a truck or trailer includes a plurality of extruded aluminum hollow floor panels wherein each panel includes spaced apart inside and outside walls connected to each other by spaced apart first and second end walls. A primary cross-member is located between and extends parallel to the first and second end walls and interconnects the inside and outside walls. The panels are abutted with each other to define a floor section including: (i) an inner load-carrying surface; (ii) an outer surface; (iii) a plurality of seams; and, (iv) opposite left and right edge regions. One-piece extruded aluminum left and right rails are connected by welding to the left and right edge regions of the floor section, respectively.Type: GrantFiled: September 10, 2007Date of Patent: June 24, 2008Assignee: East Manufacturing CorporationInventor: Howard D.

Patent number: 7374379Abstract: A winch for a cargo restraining strap includes a frame having a base and first and second parallel spaced sidewalls. The first and second sidewalls define respective first and second apertures. A protective wall extends from the base and is spaced from the first sidewall. The first sidewall and the protective wall cooperate to define a clevis structure including a channel. A pawl is movably secured to the frame, with an inner end thereof located in the clevis channel. A spool extends between the first and second sidewalls and is rotatably supported in the first and second apertures of the first and second sidewalls. A ratchet wheel is connected to the spool and is located adjacent the first sidewall. The ratchet wheel is selectively engaged by the pawl. The frame, spool and ratchet wheel can be defined from aluminum alloy. The frame can be extruded as a one-piece construction. The spool and ratchet wheel can be extruded as a one-piece construction.Type: GrantFiled: October 11, 2005Date of Patent: May 20, 2008Assignee: East Manufacturing CorporationInventor: Howard D.

Patent number: 7267393Abstract: A trailer body includes left and right bottom rails and left and right top rails all parallel to each other. A floor extends between the left and right bottom rails. A left vertical sidewall is defined between the left bottom rail and the left top rail. A right vertical sidewall is defined between the right bottom rail and the right top rail. The sidewalls are defined by a plurality of abutted extruded wall panels that extend vertically between the respective bottom and top rails. The floor is optionally defined by a plurality of abutted and interconnected one-piece extruded floor panels that extend between the left and right bottom rails. The wall and/or floor panels can include an I-beam post/cross-member defined in the extrusion profile. The panels can also define half I-beam post/cross-members so that adjacent abutted panels cooperate to define additional full I-beam post/cross-members.Type: GrantFiled: December 22, 2006Date of Patent: September 11, 2007Assignee: East Manufacturing CorporationInventor: Howard D. Booher

Patent number: 7160069Abstract: A hook hanger for a cargo trailer includes a body defining (i) a mounting bracket conforming in shape to and slidably engageable with an associated sliding winch track of an associated cargo trailer; (ii) a hook anchor connected to the mounting bracket; and, (iii) a wall that cooperates with the hook anchor to define a channel between the wall and the hook anchor. The channel opens in a side of the body, and the wall limits vertical movement of an associated hook connected to the hook anchor to prevent inadvertent disengagement by vertical movement of the associated hook from the hook anchor. The associated hook is disengageable from the hook anchor only by sliding movement in the channel in a direction transverse to vertical. A retaining member is optionally connected to the body and movable to a locked position where it captures the associated hook in the channel.Type: GrantFiled: March 23, 2001Date of Patent: January 9, 2007Assignee: East Manufacturing CorporationInventor: James H. Adams
