The three most common causes we see are power loss, travel faults, and speed problems. Before calling, check the simple things: remote or pendant batteries, tripped breakers, and an engaged limit switch. Beyond that, leave the panel closed and call. Our techs diagnose the fault on-site, usually the same day.

Follow your crane manufacturer's recommended intervals, which OSHA 1910.179 requires as the baseline for a maintenance program. In practice that means planned maintenance monthly to annually depending on duty cycle and environment. HOJ planned maintenance contracts schedule these dates for you around your inspection deadlines.

Decades, with planned maintenance. Structural components routinely outlive 25 years, while hoists, wire rope, brakes, and controls wear on cycles and need periodic replacement. When a crane's controls age out before its steel does, modernization with VFDs, radios, and new electrification extends its life at a fraction of replacement cost.

Every brand, no matter who built or installed it. HOJ performs factory-authorized warranty repairs for R&M, CM, ACCO, and Kone, stocks wear parts for CM, R&M, and Kone, and fabricates custom steel parts in-house when a component no longer exists.

It depends on the failed component, parts required, and crane access, so there is no flat rate. A technician assesses on-site, many repairs finish that same visit, and larger jobs get a written quote within 24 to 48 hours. Warranty-covered repairs are structured so the manufacturer pays as much as possible.

Often, yes. If the structure is sound, replacing worn hoists, controls, or electrification costs far less than a new crane. When repair costs approach replacement value, we tell you directly and quote both paths, and our crane engineers plan retrofits for obsolete equipment at no charge.

Common wear parts for CM, R&M, and Kone are stocked in our warehouse and on our trucks, so many repairs need no ordering at all. Approved parts orders ship same day, and our in-house certified welders fabricate custom or obsolete steel parts when no OEM part exists.

OSHA requires crane adjustments and repairs to be performed by designated, qualified personnel, so in-house fixes beyond basic checks put compliance and safety on the line. In our experience, customers who call first instead of attempting a fix usually save both time and money, since a misdiagnosed repair often compounds the original fault.

After repairs or alterations to load-bearing components, a load test verifies the crane's rated capacity before it returns to service. HOJ performs crane load testing with our own certified weights, and can often complete the test in the same trip as the repair.

The crane's make and capacity if you know them, what the crane is doing or not doing, and your facility location. That is enough for our dispatcher to open a ticket, pick the right parts for the truck, and give you an ETA.
