Our jibs are an engineered addition to the end of the crane to enable lifts that cannot be done easily with just the crane. Factory manual pullouts are not rated to the capacities we require or the profiles that serve our needs; thus the necessity of engineering and building our own. These pullouts are extremely strong fingers of steel that give us a huge advantage for interior or low profile work. Capacities are to 30,000 pounds, the hook fastens on the top of the jib rather that the bottom to minimize headroom required. Combine this with our low profile swivel hooks and we have a 2 to 3 foot height advantage over conventional rig-ups.
Our straight booms also carry jibs. With an extension jib our 38 ton straight boom has 155 feet of boom, which puts the reach over 160 feet vertical for man basket work.
Another attachment for folding cranes, are jibs we call reverse knuckles for poking through any door and delivering payloads up to 12,000 lbs. We usually work through man doors on compressors, engines, gearboxes and lathes. They are perfect for tight spots when top clearance is an issue. Most cranes are 10 feet high when mounted on the trucks. If a door is only 6 foot 6 inches, and many of them are, the item to be lifted had better not be very far inside the door because the crane tip is angled down. Our jibs change this angle, allowing the tip of the jib to position higher than the door jam well within the building.
Our reverse knuckle jibs carry special names like Kong Finger and Yellow Dog, and can reach inside up to 20 feet, with varying capacities. These special lifts require some thought and discussion. Please call our dispatch and we’ll think it through together.
The Fish Stick jib really does look like the neck and head of the Lochness Monster. It allows us to enter doors, not quite as far as our reverse systems, but perfect for heavy engines or compressors closer to access doors. The Fish Stick has a lifting capacity up to 12,000 pounds and is mounted on our 40 ton articulating crane.
We strive for continuous improvement for our customers through innovation and dynamic problem solving. So, if you find yourself confronted with a tight, sticky lift, call us, we can help.
