What the specifications mean
Working length is substantially greater than transport length because stockpiling equipment deploys around the machine. Lay out feed access and product stockpiles before deciding that the trailer fits the site.
Drum dimensions do not define the finished product on their own. Confirm aperture, drum condition, material moisture and any live-head or tipping-grid package for the job.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used 621 inspection priorities
- Inspect the drum, screen surfaces, support/drive components and cleaning brushes, then inspect the conveyors and folding hardware.
- Verify axle, tire, braking and coupling configuration against the transport documentation. Confirm which optional feed equipment is included and inspect its protective systems.
Configuration-aware inspection: these checks are triggered by machine category, installed configuration and technology package. Brochure-listed technology must be physically present, active, licensed and calibrated on the used machine.
Hours, condition and ownership cost
Hours are context, not a condition grade. Duty cycle, idle time, maintenance evidence, wear-system measurements, structural repairs and installed technology should be evaluated together.
Cost drivers to model
- Plan loading and stockpile removal so neither starves nor blocks the screen. Compare the work of the whole screening operation rather than an unsourced tonnes-per-hour estimate.
- Include drum changes, cleaning, belts and trailer running gear in the maintenance budget; options can affect both transport preparation and useful screening capability.
