How Do You Fix a Crushed Corner Cap or Front Radius on a Box Truck?

  “How Do You Fix a Crushed Corner Cap or Front Radius on a Box Truck?” A glancing blow from a pole, a misjudged turn near a dock canopy, or a low-hanging tree limb can cave in the front radius/corner cap of your box truck. The curved aluminum or FRP radius that ties the roof to the side wall is there for aerodynamics, weather sealing, and structural continuity—so when it’s crushed, owners panic: “Can you straighten that? Do I need a new panel? Will it leak forever now?” This deep-dive explains what’s actually damaged, how professionals decide between repair and replacement, what the step-by-step fix looks like, and how to avoid chronic leaks or cosmetic eyesores afterward. Quick Takeaways Most crushed front radii and corner caps are repairable without replacing the whole box body. The decision is driven by location, depth of crush, material (aluminum vs FRP), and cost vs. value —not just appearance. Proper repair involves teardown, measurement, sectioning or replacement of extru...

Liftgate Won’t Raise or Is Slow—Battery, Pump, or Cylinder Issue?

  “Liftgate Won’t Raise or Is Slow—Battery, Pump, or Cylinder Issue?” You hit the switch and… nothing. Or worse, the liftgate crawls up like it’s towing a house, then stalls a few inches off the ground. Now you’re wondering: “Is my battery dead? Pump shot? Cylinder leaking? What’s really wrong with this liftgate?” This longform guide breaks down how commercial liftgates work, why they go weak or dead, how to diagnose electrical vs. hydraulic vs. mechanical faults, what repairs typically cost and how long they take—and how to prevent the next downtime surprise. Quick Takeaways Electrical issues (low voltage, bad grounds, corroded connectors) are the #1 cause of slow or non‑responsive liftgates—check the battery and cables first. Hydraulic problems (low/contaminated fluid, weak pump, stuck relief valve, leaking cylinder seals) make gates slow, spongy, or unable to hold a load. Mechanical binding (bent arms, seized pins, warped platforms) can mimic hydraulic/electrical...

Do I Need DOT Inspections on My Liftgate?

  “Do I Need DOT Inspections on My Liftgate?” Your liftgate moves freight—and it can hurt people if it fails. So you’re wondering: “Does DOT (or anyone else) require inspections on my liftgate, and how often?” The short version: Yes, your liftgate must be safe and roadworthy under federal and state rules, and it’s covered by the same annual DOT/FMCSA inspection requirements as the rest of the truck. Beyond that, manufacturers and OSHA-style safety practices strongly recommend more frequent functional and maintenance checks. This guide explains what the law actually says, how inspectors treat liftgates, what records you need, and how to stay compliant without wasting downtime. Quick Takeaways FMCSA 49 CFR §396.17 requires a yearly “periodic inspection” of every commercial motor vehicle —that includes components like liftgates. There isn’t a separate federal “liftgate-only” DOT certificate, but the gate’s structure, hydraulics, wiring, and lighting are part of the vehicle’s i...
