Signs your liftgate was damaged in an accident

Motor City Truck Collision explains how to spot when a liftgate has been harmed in an accident and why early detection matters. Liftgates are critical work tools on box trucks, trailers, and service bodies; impacts that look minor on the surface can hide bent mounts, compromised hydraulics, or electrical faults that reduce capacity and create safety risks. This article outlines clear indicators to watch for after a collision, practical examples from common fleet incidents, and what a professional inspection should include so operators can make safe, informed decisions.

Understanding the Issue

A liftgate involved in a collision may show obvious external damage — bent platform, torn sheet metal, or cracked control housings — while also suffering internal problems. Impact forces transfer through welds, mounting plates, and brackets and can loosen or distort fasteners. Hydraulics and cylinders can be misaligned or develop hairline leaks; wiring harnesses and connectors may be stretched or pinched. For commercial vehicles, a rear-end strike, backing impact, or a heavy object shifting into the gate can create a mix of visible and hidden failures that reduce lifting capacity and compromise safe operation.

Common Causes or Warning Signs

Typical causes include backing collisions, curb strikes when lowering the platform, or cargo shifting into the gate during transit. Warning signs to watch for after any impact are slow or uneven lifting, jerky motion, platform tilt when raised, fresh hydraulic fluid on or under the gate, new unusual noises during operation, loose or missing mounting hardware, visible bends in support arms or hinges, misaligned control boxes, or difficulty locking the platform in transport position. Electrical faults such as non-functioning controls or intermittent operation can also indicate collision-related damage.

How Motor City Truck Collision Approaches This Issue

Motor City Truck Collision begins with a careful, documented inspection that checks both visible structure and functional performance. Technicians examine mounting plates and welds, test hydraulics under load, inspect cylinders, hoses and fittings for leaks, and verify electrical connections and control operation. If structural components are distorted, they evaluate whether repair or replacement is required and perform correct alignment and weld repairs where needed. Work includes proper corrosion treatment, correct fasteners, and OEM-compatible materials for hydraulic and electrical work. Quality workmanship and thorough checks reduce the chance of follow-up failures caused by incomplete repairs.

Prevention Tips or Best Practices

Perform a post-incident checklist immediately after any contact: walk around the liftgate to look for fluid, bent metal, loose bolts, and damaged wiring; operate the lift through a no-load cycle to confirm smooth motion; and note any changes in speed or balance. Train drivers on loading techniques to prevent cargo strikes, keep load weights within rated limits, and secure freight so it cannot shift into the gate. Maintain hydraulic fluid levels and change filters per manufacturer guidance. In Michigan, regular underbody and liftgate washing helps remove road salt that accelerates corrosion and weakens mounts over time.
