Suspension Duty & Application Your trailer application may be for mostly On-Highway or may be more heavy duty requiring a suspension for Off-Highway durability. The Binkley series is rated up to 25,000 lbs. GAWR with proper springs, axles, and brake selection. o o The Binkley Standard (S) model is designed to be an industry leader for On-Highway applications: durable, light weight, with value added features and options: Container Chassis, Gravel, Dump, Belly Dump, Rear Dump, Livestock, Grain, Platform, Van, Lt Wt Utility, Tag & Pindle. The Binkley Heavy Duty (H) model is designed with thicker gage hangers and parts to be an industry leader for Off-Highway applications: Lowboy, Oil-Field, Logging, Tanker, Chip Van, HD Drop-deck & Flatbed. P/N Suspension Duty (Up to 25K with proper spring selection) S = Binkley Standard, Mostly On-Highway (Features light weight front and rear hangers, replaceable hanger wear pads.) H = Binkley HD, Off-Highway (Features heavy duty hangers, replaceable hanger wear pads.) Axle Quantity Your trailer application may require a single or multiple axle configuration. To reconfigure from a single or tandem kit an expansion Multiple Axle Configurator (MAC) kit can be added. P/N Axle Quantity 1 = Single Axle Configuration 2 = Tandem Axle Configuration 3 = Tri-Axle Axle Configuration 4 = MAC Kit (Axle add-on kit) pg. 3
Axle Spacing Your trailer application will determine the axle spacing needed. The standard axle spacing is 49, axle spacing wider than 49 will require a special length rocker or custom configuration. P/N Axle Spacing A = Single Axle Standard Setting C = 42.5" Axle Centers (12K Lt Wt Special Spring) E = 49" Axle Centers (11.75 long rocker) SHOWN H = 54.5" Axle Centers (17.25 long rocker) J = 60" Axle Centers (22.75 long rocker) Axle Connection Configuration Your trailer application will often determine what height of suspension you need to fit between the bottom of the trailer frame and the center of the axle (Suspension RIDE HEIGHT, RH). The suspension Ride Height required will then determine if your application is tall or short application. A tall application will require an Overslung, or TopMount type typically used on Flatbed or Van trailers. A short application will require an Underslung, or Low-Mount type typically used on Drop-Deck or Lowboy trailers. The axle connection brackets are also dependent on the size of the axle. A standard axle is 5.0 round diameter and a light weight axle can be 5.75 or 6.0 round diameter with a thinner wall to reduce weight at the same strength as a 5.0 round. Overslung Axle Connection Underslung Axle Connection No Catch bottom spring seat protects u-bolts better than others and increases under ground clearance.

Hanger Styles Your trailer frame design will determine what style of frame hanger will fit up best for your trailer type & application. These hangers are offered in both the Binkley S and the Binkley HD style units. (U) UnderMount, No Top Plate Tapered Top Hanger for 4 I-Beam (S) UnderMount, Straddle-Mount For 4 Tube P/N Hanger Style U = Under Mount Narrow, No Top Plate T = Under Mount with Top Plates S = 4" Wide Straddle Mount W = Under Mount Narrow, Winged no Tops F = Flange Mount Weldon B = Flange Mount Bolton X = Other T.B.D. in Spec Notes 0 = None / Completion Kit Reference Trailer Type & Hanger Style I-Beam Frame I-Beam or Tube Frame Tube or G-rail Frame I-Beam or Slider Frame Tank Trailer Frame Aluminum Trailer Frame pg. 5
Spring Seat Height Your trailer frame design will determine what system Ride Height is needed. Per your spring choice the spring seat height (SS) will be shown in the chart for the desired ride height. The spring seat connects the axle to the springs and the suspension torque arms. Spring seats need to be chosen for ride height and axle diameter fit-up. A standard axle is 5.0 round diameter and a light weight axle can be 5.75 or 6.0 round diameter with a thinner wall to reduce weight at the same strength as a 5.0 round. Below is a chart showing the alpha ID letter for each type of seat.

Spring Choice Customers can get their Cush Binkley Series leaf springs from us or source them internally. There are several springs to choose from for desired capacity and ride quality. Please review your ride height and spring requirements. Customers can provide their own leaf springs but we need to know what spring is being used so that we can verify the application use.
