Why boom trucks need special collision inspections

Boom trucks combine the vulnerabilities of a heavy chassis with the complex mechanics of a lifting boom and outriggers. Motor City Truck Collision explains why boom trucks need special collision inspections so fleet managers and operators can spot hidden damage, protect lifting capacity, and maintain safe operation.

This article outlines how impacts affect boom assemblies, mounts, and chassis structure, what signs to watch for during routine checks, and practical steps to reduce long-term repair needs while keeping crews and equipment safe.

Understanding the Issue

A boom truck collision is more than a dented panel—forces transfer through the boom into pivot points, outriggers, and the vehicle frame. When a boom strikes an object, or an outrigger lands on an uneven surface, stress concentrates at welds, mounting plates, and pin connections. Telescoping sections and sheaves can experience misalignment while wire rope and hydraulic lines may be damaged out of sight. Because these components carry lifting loads, even modest impacts can reduce capacity, change boom geometry, or create fatigue points that grow into major structural failures if not discovered and repaired properly.

Common Causes or Warning Signs

Typical causes include improper placement of outriggers, hitting low structures while slewing the boom, unsecured loads swinging into the boom or jib, and backing incidents in tight yards. Warning signs to catch early include unusual play at pivot pins, difficulty extending or retracting telescopic sections smoothly, new or growing hydraulic fluid leaks, visible cracks around mounting plates or welds, bent outrigger beams, and abnormal boom deflection under light loads. Crews should also notice changes in lifting feel, odd noises during operation, or misaligned hook travel paths.

How Motor City Truck Collision Approaches This Issue

Motor City Truck Collision begins with a detailed visual and functional inspection that checks the boom, sheaves, wire rope, hydraulic lines, outriggers, and the chassis attachment points. Technicians look for surface damage and follow up on suspected structural issues with measurement checks and targeted testing when needed. Repairs focus on correct disassembly, proper welding and reinforcement where appropriate, renewing pins and bearings, repairing or replacing damaged hydraulic components, and restoring correct boom geometry. Work includes careful corrosion prep and paint to protect repairs. Every repair emphasizes skilled technicians, documented inspections, and doing the job right to prevent return visits and progressive failures.

Prevention Tips or Best Practices

Perform a pre-use checklist that includes a close look at outriggers, pins, sheaves, wire rope condition, and hydraulic lines. Park and deploy outriggers on solid, level surfaces or use properly rated pads; avoid positioning near curbs or soft ground. Train operators on swing clearances, spotting for low structures, and safe lifting practices to minimize boom contact. Keep a maintenance log of inspections and repairs, lubricate pivot points regularly, and address small cracks or paint damage before corrosion accelerates. In Michigan, rinse undercarriages and exposed metal during winter to remove road salt that can speed corrosion at welds and mounts.
