Diamond C PSA135 12 Foot Single Axle Utility Trailer, Cement Gray

Description

Hauling lawn mowers and building materials becomes straightforward with the Diamond C PSA135 Utility Trailer. A single 3,500 lbs Dexter idler axle supports equipment inside a 12ft bed while maintaining easy towing behind half-ton trucks. The spring-assist bi-fold gate reduces wind resistance. The open utility sides require tarping when hauling loose mulch or gravel.

Formed from 3in by 2in rectangular steel tube framing, the chassis resists torsional flex under off-center loads. Pressure-treated southern yellow pine flooring covers a floor stance measuring 77in wide by 144in long. Running gear features a 3,500 lbs Dexter cambered axle, 4-leaf double eye springs, and ST205/75R15 radial tires on 5-bolt steel wheels. Empty trailer weight measures 1,420 lbs, leaving a practical payload capacity of 1,570 lbs.

Key Features of Diamond C PSA135

Property care contractors buy Diamond C PSA135 trailers for regular transport of commercial zero-turn mowers. Request municipal quotes for commercial fleet pricing when upgrading outdated single-axle haulers.

Axle Flex Static Load Benchmarks

Static load testing shows less than 0.080in frame rail deflection under 1,500 lbs concentrated machine weight. Leaf spring travel measures 1.60in across deep road depressions, preventing chassis bottoming under maximum rated payload. Dexter axle camber geometry keeps tire tread flat against the road under load, extending tire life. High-speed highway tests record zero trailer sway at 65 MPH behind a half-ton pickup. Interior truck cab noise monitors confirm quiet towing at 66 dB over grooved concrete.

Ramp Gate Usability Maintenance Protocols

Lifting the bi-fold rear gate requires 14 lbs hand effort due to integrated coil spring assists. Do not purchase this trailer for transporting skid steers, mini-excavators, or heavy bulk aggregate.

• Torque 15in wheel lug nuts to 90 ft-lbs every 500 miles.
• Inspect treated wood deck screws for tightness every 60 days.
• Lubricate rear gate hinge pivot pins with grease every 30 days.
