04-6152-5011 - Tronair 04-6152-0120 Hydraulic Utility Crane, 2,750-lb Capacity

The Tronair 04-6152-0120 Utility Crane is used in aviation maintenance for tasks such as engine changes, stabilizer removal, and other component lifts that require precise control and reliability. Its hydraulic design provides steady lifting power suitable for both light and heavy maintenance operations. The crane’s rugged base and counter-weighted structure ensure stable, controlled handling during aircraft service procedures.

Operators must always read and understand the manual before use, ensuring they observe all warning and caution notices provided by Tronair. Personnel should stay clear of suspended loads, never modify the crane, and verify that safety pins and locking mechanisms are fully engaged before lifting. Using only Tronair-approved replacement parts also helps maintain compliance with operational safety standards.

Installing the K-2012 Gooseneck Boom Kit increases the crane’s maximum height to approximately 275” (698 cm), allowing for higher lifts and improved access to elevated aircraft components. It extends the main boom while maintaining safe load handling, but operators must follow the rated-capacity chart on the crane column to prevent overloads. Proper pin placement and secure installation are essential for safe operation.

Routine maintenance includes inspecting pivot bolts, hydraulic lines, and cylinders for leaks, corrosion, or deformation. Lubricating pivot points, maintaining fluid levels with MIL-PRF-5606 hydraulic fluid, and checking the velocity fuse for functionality are all recommended. Maintaining an inspection log in accordance with ASME B30.20 standards helps ensure compliance and long-term reliability.

Inspections should be conducted before each use, with periodic and annual checks performed in accordance with Tronair’s maintenance guidelines. Normal service requires yearly inspection, heavy use calls for semi-annual checks, and severe conditions demand quarterly reviews. Annual load testing up to 125% of rated capacity is also required to verify performance and compliance with OSHA 1910.179 standards.

Yes. With the optional K-2013 Pneumatic Air Pump Kit installed, the crane can be operated using 125 PSI (8.6 bar) shop air, reducing manual effort and improving operational speed. The air-driven pump connects directly to the hydraulic circuit and provides precise control over boom movement using its integrated flow and shut-off valves.

The optional K-2953 Heavy-Duty Hand Winch Kit is manually operated and includes a load-holding brake that engages whenever the handle is released. Operators should maintain at least four cable wraps on the drum at all times, avoid using kinked or frayed cable, and never stand under a suspended load. The winch is designed for intermittent use only and should never be used to hoist personnel.

Before using the crane, check all fasteners, verify the relief valve and hydraulic cylinder are leak-free, and confirm that casters, locks, and cables are intact. Examine the structure for cracks, corrosion, or deformation, and confirm that load charts are legible and visible. Correct any deficiencies before operating to ensure full load capacity and personnel safety.

The inline velocity fuse prevents rapid load descent in the event of a hydraulic line failure. It automatically locks the hydraulic flow if the fluid speed exceeds safe limits, keeping the load suspended until the system is manually reset. This safety mechanism provides critical protection for operators and aircraft components during heavy lifts.
