Detailed Description for 5 Ton Freestanding Jib Cranes- 12' HUB (Height Under Boom)- Series (100-102)- Spanco Make

FREE STANDING JIB CRANES

 

Spanco Freestanding Jib Cranes install almost anywhere, including outside. These foundation-mounted, freestanding jibs offer higher capacities, longer spans, and greater rotation.

• 360° rotation.

• Allows for electrified, motor driven, powered rotation through various collector ring assemblies.

• The boom or I-beam is designed to meet all specifications

utilizing a 25% factor of rated load for impact and 15% of rated load for hoist and trolley weight.

• The pipe mast or column is designed to give maximum strength and minimum deflection to resist bending, buckling, and crushing as well as wear by the trunnion roller assembly.

• The top bearing assembly utilizes a Timken tapered roller bearing provided with a grease fitting for proper lubrication.

 

• The bearings are designed for a 5000 hour, B-10 design life.

Installation 100 Series - Base Plate Mounted Freestanding Jib Cranes: 

 

1. a. Install one set of nuts on anchor bolts with top surface of nut approximately one inch above foundation. Place mast/base unit over anchor bolts resting on leveling nuts.

 b. Bolt pads are tac welded to base plate for easy removal in case of slight misalignment of anchor bolt. Grind a tac area to remove bolt pad(s). Reset mast unit over anchor bolts and leveling nuts. Be sure to replace bolt pad(s) back into place before the second set of nuts. Bolt pads do not require welding once that are removed and replaced.

 c. Install second set of nuts loosely, and insert plumb line arm in pivot shaft located on top of mast. Select position on arm to hang plumb line that is two inches from edge of mast. Measure 60 inches down from top of mast, and use that point to check plumb. Locate arm directly over one anchor bolt (or pairs when 12 bolts are used). Measure from plumb line to edge of mast. Measurement should be two inches. If not, adjust leveling nut. Rotate arm 180 degrees, and check distance. If distance is more or less than two inches, adjust leveling nuts to the same distance on both sides of mast.

d. Repeat operation at each anchor bolt (60-degree increments). When mast is plumb, float grouting compound under base plate, and tighten locking nuts.

 

2. Box/Head assembly

a. Box/head assembly is mounted on main bearing of pivot shaft.

b. To level box assembly, adjust hex nuts to adjust the position of roller assembly to mast. When box is fairly level, place flat washer over pivot shaft protruding through head assembly of box, and secure with remaining snap ring.

 

3. Boom assembly

a. Mount boom assembly to box securing at back plate and beam support angle.

 

b. Modify boom by adjusting the roller adjustment nut; lock into position with lock nuts.

Method of calculation: Dim. A ÷ 300 = adjustment above level (span in inches)

 

101 Series - Base Plate Mounted Freestanding Jib Cranes

Main Features:

• No knee braces, freeing up area at foot of crane’s mast.

• Square steel plate comes welded to bottom of mast.

• The plate positions and plumbs the mast by anchoring it to the first-pour concrete footing.

 

• The second-pour supports the mast

Installation 101 Series - Base Plate Mounted Freestanding Jib Cranes: 

 

1. Mast/Base Assembly

After installation of recommended first pour concrete (3000# P.S.I.) footing with anchor bolts, refer to specific model dimension sheet of your jib crane. Install one set of nuts on the anchor bolts with the top surface approximately one inch above the foundation. Then place mast/base unit over anchor bolts resting on leveling nuts. Install second set of nuts loosely, insert plumb line arm in main pivot located on top of mast. Select position on arm to hang plumb line that is 2” from edge of mast. Measure down from top of mast 60 inches, use this point for checking plumb. Locate arm directly over one anchor bolt, measure from plumb line to edge of mast, should be 2”, if not, adjust leveling nut directly below, up if greater than 2”, down if less than 2”. Rotate arm 180 degrees, check for 2” distance, if not, adjust leveling nuts until you have the same distance on each side of mast. Repeat this operation at each anchor bolt (90 degree increments). When mast is plumb float grouting compound under base plate and tighten locking nuts. Install 3 braces from top of mast to ground at 120 degrees apart to prevent mast from shifting when concrete foundation is poured. After concrete has hardened proceed with jib assembly.

2. Box/Head Assembly

The box/head assembly is mounted on main bearing on pivot shaft, then box assembly is leveled by adjusting hex nuts (9), which adjust position of roller assembly to the mast, thereby leveling box assembly. When box is fairly level, place flat washer over pivot shaft protruding through head assembly of box, and secure with remaining snap ring.

3. Boom Assembly

Mount boom assembly directly to box securing at back plate and beam support angle . Then adjust boom, such that the end of the beam is ___ inches above level, by evenly adjusting the roller adjustment nut and lock into position with lock nuts. (use calcuation to determine inches required)

Method of calculation: Dim. A ÷ 300 = adjustment above level (span in inches)

 

102 Series - Base Plate Mounted Freestanding Jib Cranes:

Main Features:

• Allows for crane relocation without damaging the mast.

• No knee braces, freeing up area at foot of crane’s mast.

• Sleeve is welded to square steel plate; the plate positions and plumbs the sleeve by anchoring it to the first-pour concrete footing.

• The second-pour supports the sleeve.

• The mast is placed into the sleeve, leveled by wedges, and welded in place.

 

 

Installation 102 Series - Base Plate Mounted Freestanding Jib Cranes:

1. Mast/Base Assembly

After installation of recommended first pour concrete (3000# P.S.I.) footing with anchor bolts, refer to specific model dimension sheet of your jib crane. Install one set of nuts on the anchor bolts with the top surface approximately one inch above the foundation. Then place insert sleeve base over anchor bolt resting on leveling nuts. Install second set of nuts loosely, plumb sleeve and tighten locking nuts and secure top of sleeve to ground with three braces at 120 degrees to prevent sleeve from shifting, when second foundation is poured. After concrete has hardened, insert crane mast into sleeve and over the sleeve aligning pin, making sure that the aligning pin is fully engaged with the hole in the bottom mast plate. Insert plumb line arm in main pivot located on top of mast. Select position on arm to hang plumb line that is 2” from edge to mast. Measure down from top of mast 60 inches, use this point for checking the plumb. Insert 4 steel wedges between sleeve and mast at 90 degree increments. Locate arm directly over one wedge, measure from plumb line to edge of mast, should be 2” if not, adjust wedges, rotate arm 180 degrees check for 2” distance, if not, adjust wedges for the same measurement each side of mast. Repeat this operation at each wedge (90 degree increments). When mast is plumb, weld wedges in place and proced with jib assembly.

2. Box/Head Assembly

The box/head assembly is mounted on main bearing on pivot shaft, then box assembly is leveled by adjusting hex nuts , which adjust position of roller assembly to the mast, thereby leveling box assembly. When box is fairly level, place flat washer over pivot shaft protruding through head assembly of box, and secure with remaining snap ring.

3. Boom Assembly

Mount boom assembly directly to box securing at back plate and boom support angle . Then adjust boom, such that the end of the beam is ___ inches above level, by evenly adjusting the roller adjustment nut and lock into position with lock nuts . (use calcuation to determine inches required)

Method of calculation: Dim. A ÷ 300 = adjustment above level (span in inches)
