STEP#1 BASE ASSEMBLY L-25 MINI TOWER 4 A) Assemble 4 legs to hinged base assembly with (4) 3/8-16 x 3 1/2 grade 5 bolts using (2) flat washers and (1) nut for each. B) Assemble a leg brace to each of the legs using a 3/8-16 x 3 1/2 grade 5 bolt and (2) flat washers and (1) nut for each. Attach 3 of the braces as shown using the t-pins and leave the brace out on the slide plate side.
L-25 MINI TOWER STEP#2 5 WINCH & TOWER ASSEMBLY A) Attach winch using (5) 3/8-16 x 1 1/4 grade 5 bolts using (1) flat washer and (1) nut for each. B) Wind the cable onto the winch paying close attention that the cable does not cross itself. C) Remove bolts and pivot hinge to attach tower sections.
L-25 MINI TOWER STEP#3 6 TOWER ASSEMBLY A) Attach the tower sections and the head block using the required grade 5 3/8-16 x 1 1/4 bolts and (1) flat washer and (1) nut for each. B) Attach the slide block to the assembled tower. Note: Check the hole locations on the slide block for the model truss you are using. Some bolts may have to be inserted before the slide block is installed on the tower.
STEP#4 ATTACH CABLE & RAISE TOWER L-25 MINI TOWER 7 A) Unwrap the cable and feed it around the head block (remove and replace retaining pins above the pulleys) and connect to the slide block aligning the thimble between the angles and inserting the clevis pin. B) If towers are outside, now is a good time to attach the guy wires. Refer to the engineering document for number and locations of guy wires. Rope over head block. C) We suggest attaching a rope over the top of the tower, down the other side and secured at a location you can reach from the ground. Have 1 person pull the rope while 2 people walk up the tower to vertical. Disconnect the rope once the tower is secure.
L-25 MINI TOWER STEP#5 8 Secure Tower Check List 1) Tower should be standing erect and level 2) All outriggers attached to base and 3 outrigger braces secured to tower. 3) The winch attached to tower. 4) The cable routed thru head block (pins reinstalled in head block) 5) Cable attached to slide block and slide block located at bottom of tower. A) With tower fully raised, insert the (8) 3/8-16 x 1 1/4 bolts, washers and nuts to secure hinge section.
L-25 MINI TOWER STEP#6 9 Raising The Structure Note: Each winch must have a MINIMUM of 300 lbs of load to work properly. Each winch on each tower must be cranked in unison to prevent binding. A) With structure attached, (minimum of 300 lbs each winch) raise to a height that will allow the final leg brace to be installed with a (1) 3/8-16 x 3 1/2 grade 5 bolt, (2) washers and (1) nut. All of the slack should be removed from all of the braces with the leveling screws.
