Bucket Elevator
3. Rig a heavy haulage line (rope or cable) through the removable panel in the UP-LEG through which
the belt with buckets attached will be pulled into the elevator. The line is then hauled up the
UP-LEG
,
over the head pulley, and down the
DOWN
elevator leg. Usually, the line can be passed around the
boot take-up pulley and out of a cleanout panel to a winch so the belt can be pulled into the elevator.
A spreader bar should be fabricated to connect the haulage line to the belt. See
. The bar is preferred to simply punching a hole in the belt and tying or clamping the line
to the belt.
4. “ACME” Nuts should both be tightened against support plate to prevent vibration from moving the
take-up out of alignment. Should the take-up screw ever require replacement make certain to loosen
both “ACME” Nuts to relieve any upward or downward tension before removing the retainer bolts.
5. The connection bolts must be loosened while aligning pulley with adjusting screws and retightened
when alignment is complete. Do not add weight to the weight box unless otherwise instructed by the
factory. The weight of the take-up, boot bearings, etc., provides proper belt tension in most
applications. Additional weight may cause damage to the belt.
Method 1: Simultaneous Belt and Bucket Installation (Less than 100')
IMPORTANT: Omit at least three (3) rows or sets of buckets at each end of the belt until after the belt has
been spliced.
1. Place a flat table in-line with an opening in the Up-leg trunk of the elevator, usually the end panel in
the boot section. Remove the boot end panel.
2. Arrange the roll of belt so it can easily be unrolled onto the worktable and then into the elevator’s
UP-leg. Follow the belt manufacturer’s recommendations, if any, as to which side of the belt should
contact the pulleys and which side should face outward and contact the buckets.

3. The belt should already have the bucket mounting holes prepunched in the appropriate pattern.
Begin bolting buckets to the belt in the pattern and at the spacing shown on the drawing. The heads
of the elevator bolts bear against the inside surface of the belt. Buckets are to bear against the
opposite or outer surface of the belt. Elevator bolts should be tightened so as to draw the heads flush
with the belt surface. This prevents the bolt heads from scarring the pulleys or working loose. Refer
to hardware manufacturer for recommended installation and torque criteria.
