Length: The bucket length is measured at the back mounting surface. Lay the bucket on it’s back for actual measurement dimensions from end to end. 

 

Projection: Projection is measured vertically to the lip as it would project from the belt or chain. With the bucket still lying flat on its back, measure up to the highest point of the bucket lip.

 

Depth: Depth is measured for the overall side profile dimension. Again, with the bucket lying flat, measure the from top to bottom of the back of the bucket.

#1 Vent: Same number of holes in the body as the mounting holes
#2 Vent: One row of holes on 1-1/8” centers.
#3 Vent: Two rows of holes on 1-1/8” centers.
#4 Vent: Same as #3, plus three holes in each end cap.
Custom Vent: Special vent patterns as requested.


If you aren’t sure which to choose, reach out to the Maxi-Lift team for guidance.

 

Bucket application – what is the material being elevated and what is the temperature?
Bucket size – what are the measurements of the current buckets?
Bucket material – is the bucket polyethylene, nylon, urethane, ductile iron, carbon steel or stainless steel?

 

Does the bucket need to be low-profile?
Does the bucket need venting holes?
What is the mounting bolt hole pattern?
What style of bucket is needed? – please consult the Maxi-Lift website to see all the styles available.

If plastic buckets are attached to a static conductive belt with steel (conductive) bolts and the belt travels over conductive pulleys that are part of a properly grounded bucket elevator, the system will safely conduct any static electricity that’s generated.


There’s no historical evidence that plastic buckets have ever caused a spark that led to a dust explosion.


Plastic buckets have been in use since the 1950s.


Plastic buckets won’t cause a spark even when they meet an obstruction.


None of the Maxi-Lift poly materials (polyethylene, urethane and nylon) can generate a sufficient volume of electric charge to produce a blue static spark.

 

  1. Maxi-Lift recommends the use of a cordless drill or impact driver that has an adjustable clutch system to manage torque. For a demonstration see our YouTube Video below.
  2. Set the clutch mechanism to a lighter torque setting to begin.
  3. Attempt to tighten the fasteners on the first bucket using this light torque setting. If this setting results in seating the bolt just flush into the back cover, then proceed. If it does not seat the head into the cover, or pulls it in too deeply, then adjust the clutch so the desired result is achieved. You are looking to just get the head flush into the cover.
  4. Working left to right, repeat the process until you get a consistent result. Once you consistently get the bolt heads to seat, complete the remaining bucket installation, alternating the direction on each consecutive bucket to avoid causing the belt to bow out.
  5. Do not overtighten the bolts, as this will cause high spots or humps between the bolts. These high spots will become wear points on the belt and will wear out before the rest of the belt.
