A guy with 30 years' experience watched me lift a 4-ton AC unit and said I was asking for a swing accident. Switched to tighter taglines and now I can actually control the load in windy conditions. Anyone else get called out on something they thought was fine?
This old crane hand named Frank at the Port of Seattle yard called me out for just pointing and nodding instead of using proper hand signals. He was right, I was cutting corners and it could have gotten someone hurt. Now I do the full arm signals every time, even for small moves. Has anyone else had a salty vet call them out on something basic?
I was going through some old service records my dad left from when he ran this business back in the 90s. Found a note saying the brake drums on our 1985 Grove RT were originally 1.5 inches thick when new, but after I measured them last month they were barely 0.9 inches. That explains why the stopping distance felt off on that job in Portland three weeks ago. Has anyone else checked their older rig's brake drums against the factory spec?
I dropped two grand on a brand new remote control setup for my crawler crane last year, thinking it would make everything easier. First week on a job site in Newark, the thing kept losing signal every time I got near a steel beam. My old pendant system never had that issue. Has anyone else had problems with those newer wireless systems or am I just the unlucky one?
I learned this the hard way last month at a job site near the Port of Seattle. My Liebherr LTM 1050 was showing a 3-ton discrepancy on a pick (you know, the kind where you really need it to be right). Turns out the load cell drifted after 11 months and nobody caught it until we lifted a test weight. Has anyone else had calibration drift faster than the manual says?
Been fighting with chains all week on a job site near the coast. Wind was gusting hard and my usual setup kept shifting. Lost an hour resecuring the second pick. Foreman told me to try ratchet straps as a temp fix. Figured it would snap but the load stayed put for three more lifts. Has anyone else used straps for windy conditions or am I just lucky so far?
I bought a used Radiocan remote setup off a guy on Craigslist (around $600) because I was tired of climbing up and down for every little adjustment. Last Tuesday, I was setting a steel beam in tight quarters and didn't have to signal my oiler once, just watched from the ground. Anyone else find that spending money on the control side beats spending it on the machine itself?
I ran a new Grove for about 6 months back in 2021 and that thing was all computer nannies and error codes. Switched to a 2013 Liebherr LTM 1050 last spring and the hydraulic controls just feel right, no software fighting you. Anyone else find the older models just talk to you better through the levers?
Lifted a 12 ton AC unit onto a hospital roof in Cleveland and the wind was dead calm, the ground was stable, and the spotter didn't second guess a single signal. Anyone else ever get a day where the load feels like it's floating on air?
I was setting a big AC unit on a roof last Tuesday in Denver and the wind was only like 15 mph steady. But when I got that load up around 80 feet it started swinging way more than I expected. Went home and looked up some crane wind charts and learned that a 15 mph wind at ground level can be 25+ mph at boom tip height. Crazy how much difference the altitude makes especially out here. Has anyone else gotten caught off guard by wind at height?
I was setting up a Grove RT550 at a job site off I-35 and couldn't get the third boom section pinned. Turns out the pin was sitting in the toolbox, not in the storage slot where I always keep it. Has anyone else wasted half a shift hunting for something that was right under your nose?
Was working a tight spot near I-95 last month and my signal guy took too long with the hand cues. Almost boomed the load into a parked car. Now I make everyone use radios, way faster. Anyone else drop hand signals for radio comms?
I had this job out near Modesto where I needed to set a steel beam on top of a 5-story frame. Problem was my reach was just a few feet short with the standard boom. Old school foreman told me to try the 3-block approach where you extend the boom while it's under load. I mean everyone says never do that, right? But he showed me this specific technique with a slow gradual extension and a tagline setup. The other option was driving 45 minutes to swap rigs. I tried the 3-block thing and it worked perfect no drama. Got the beam set in 20 minutes. But now I'm wondering if I just got lucky or if there's places where this legit makes sense. Any of you guys ever do this or is it just a bad habit waiting to bite me?
Saw a guy at a job site in Austin last month get too casual with his boom swing and clipped a brand new F-150 mirror. Cost the company $1,200 just for the repair. Ever since then I tie off a flag line to mark the danger zone, and it's saved me twice already. Anyone else add extra steps after a close call?
I was reading through the manual for my old Grove RT540E last night and stumbled on the safety factor specs. Turns out most mobile cranes are built to handle 300% of their max rated load before anything actually breaks. That blew my mind cause I always figured it was like 150% tops. Has anyone else ever looked up the real test data for their rig?
I was setting up a 50-ton Grove for a steel beam lift at a warehouse job in Tulsa, and the outrigger pad sank right into a soft spot in the asphalt nobody flagged. Spent 4 hours re-leveling and waiting for the ground crew to bring steel plates, and the foreman kept yelling at me like I picked the spot myself. Has anyone else had a site manager just refuse to take blame for bad ground prep?
The jib was pointed straight into the wind with the hook hanging loose and no tagline tied off, which seems like asking for trouble if a gust picks up - has anyone else seen setups that looked sloppy near turbine sites?
Last Wednesday I was doing a tandem lift with another crane on a steel beam that weighed about 12 tons. We had it all rigged up and both of us were on the same radio channel, but when we started lifting, the other operator pulled ahead by maybe 6 inches and the whole load started swinging nasty. I had to yell at him to stop and reset. Learned the hard way that even with radios, you need to pick a lead operator and have everyone else just follow their commands, no matter what. Any of you guys have a system for tandem lifts that works better?
He said something about how he runs his outriggers on soft ground that got me thinking. I always just throw down the pads and hope for the best, but he said he spends 15 minutes checking every spot with a probe first. Said he learned that after a tip in the 90s that almost killed his partner. I don't know, maybe it's just me but I never really thought that deep about it. You guys do any extra ground checking before setting up?
I spent 3 hours yesterday fighting a brake caliper bolt that was seized on a 1998 Liebherr LTM 1050. The manual said 20 minutes max, but that bolt laughed at my impact wrench. Has anyone else run into rusted bolts on older cranes that just refuse to budge?
I was dead set on getting this aftermarket jib for my 50-ton Grove last month. Figured it would help me with those tight reach jobs where I'm always just a few feet short. The salesman swore it would pay for itself in six months. But then this retired operator at the supply yard pulled me aside and asked how many times a year I actually need that extra 20 feet. I did the math right there... maybe four or five jobs max. At $400 plus install time and the extra weight on the crane, it would take like three years to break even. Now I just rent a bigger rig for those rare jobs and pocket the difference. Has anyone else almost dropped serious cash on something you use maybe twice a year?
Used to always second-guess myself with hand signals on big tandem lifts, especially with my old Grove. Last week on a job near Columbus, my partner and I lifted a 40-ton HVAC unit without a single wobble. I finally trusted the hand signals and our rhythm, and the foreman even said it was the cleanest pick he's seen. Any of you guys have a moment where the communication just clicked?
The site was this tight patch between two old buildings on 16th Street. I had maybe 6 inches of clearance on each side of the tracks. The ground was soft from recent rain and I could feel the crawler sinking just a little with each step. My spotter was yelling directions but the wind was whipping so bad I could barely hear him over the engine. I had to stop and reset three times before I even got past the first corner. It took almost 2 hours just to get it positioned where we needed it for the steel beams. Has anyone else dealt with super tight urban sites where the ground gives out under you?
Picked the 50-ton thinking it'd squeeze in the alley better, but the reach was off by about 6 feet and I had to re-rig the whole load on a concrete slab. Anyone else get burned by picking the smaller crane just to fit the site?
Was on a high rise job in Denver last Tuesday. Old iron guy told me he stopped trusting hand signals after a miscommunication nearly dropped a load on his buddy. He said he just uses radios now for everything critical. Any of you guys still fully trust hand signals over radios?
