A luffing jib pinned out of sequence puts the load and the crew at risk. The Manitowoc 2250 #133/133A Luffing Jib operator manual PDF is the factory guide that prevents it: 172 pages under OEM ID 015-06, written for the 2250 crawler crane rigged with either luffing jib. Set-up and installation takes up the largest share of the book, from jib butt and backstay pendants through pre-raising checks and outside assist raising and lowering. Wire rope reeving gets its own chapter, and your boom stop, jib stop and block-up limit adjustments come with wiring diagrams. Spool 975 ft (297 m) of 1 in (26 mm) rope onto the boom hoist and 1,200 ft (366 m) of 7/8 in (22 mm) onto the luffing hoist. Order the wrong diameter and you pay for two reels. Bookmarks and a searchable text layer put the right rope spec in front of you before you order, so the crane is rigged, inspected and lifting again.

Manitowoc 2250 #133/133A Luffing Jib Common Problems This Manual Covers
Manitowoc 2250 block-up limit control not stopping hoist when load block is raised too high
Inspect the limit switch and electric cord for damage, then adjust the switch lever following page 167. Set Dimension A on the limit switch lever to 1.04 in (26 mm). Verify the cord is connected correctly, then raise the block slowly and confirm the hoist stops before you go back to lifting.
Manual Section: Block-up Limit Control Adjustment p. 167Automatic boom stop not stopping boom at maximum angle during boom hoist raising
Test the boom stop with the bypass limit test before the shift and watch whether the boom stops at the set angle. If it does not, perform the boom stop maintenance checks, then adjust the MAX and MIN boom stops per the Automatic Boom Stop Adjustment procedure. Retest both limits before raising the boom under load.
Manual Section: Automatic Boom Stop AdjustmentLuffing jib stop limits MAX UP or MAX DOWN not engaging at set boom to jib angle
Verify whether your crane is past or current production before touching anything; the jib stop procedures differ. On current production machines, perform the maintenance checks, then adjust the MAX UP 1, MAX UP 2 and MAX DOWN limits. Past production units use MAX and MIN boom to luffing jib angles instead. Retest every limit before lifting.
Manual Section: Jib Stop Adjustment - Current ProductionBoom or luffing jib angle indicator reading does not match actual boom angle
Check the angle indicator against a known boom angle before trusting it on a lift. Adjust the indicator per the Angle Indicator Adjustment procedure, and if it still reads wrong, replace the sending unit assembly. When removing the luffing jib, follow the steps for disconnecting the luffing jib angle indicator first.
Manual Section: Angle Indicator AdjustmentWire rope clips loose or slipping at wedge socket after reeving load line
Torque rope clip nuts following page 131: 225 ft/lbs (0,30 kN/m) for 7/8, 1 and 1-1/8 inch rope, and 360 ft/lbs (0,49 kN/m) for 1-1/4 inch rope. Check the anchoring to the wedge socket matches the installation steps, then break in the new rope before taking a working load.
Manual Section: Wire Rope Installation p. 131Jib diagonal lacing connecting nuts found loose at lacing supports during jib installation
Clean all dirt from between the lacings and lacing supports before you tighten anything. Torque the connecting nuts dry to 300 ft-lb (407 Nm) following page 67; no lubricant on the threads. Recheck every diagonal lacing connection before you install the jib inserts and top and raise the boom and jib.
Manual Section: Jib Storage and Installation p. 67Frequently Asked Questions
What are the torque specs for the diagonal lacing bolts on the Manitowoc 2250 #133/133A Luffing Jib boom inserts?

What torque should the rope clip nuts be tightened to on the Manitowoc 2250 #133/133A Luffing Jib wire rope?
The torque for rope clip nuts depends on the wire rope size. For 7/8 inch (22.23 mm) rope, the torque is 225 ft-lbs (0.30 kN/m). For 1 inch (25.4 mm) and 1-1/8 inch (28.58 mm) rope, it is also 225 ft-lbs (0.30 kN/m). For 1-1/4 inch (31.75 mm) rope, the torque is 360 ft-lbs (0.49 kN/m). p. 131
What is the maximum single line pull for the No. 1.5 pad eye used for wire rope reeving?
The maximum single line pull for the No. 1.5 pad eye is 1,000 lb (4.45 kN). p. 132
What is the required dimension for the block-up limit control actuating lever adjustment?
