  • No obstructions means easier, more efficient cleaning

Greenrak optional seismic track

  • Surface-mounted seismic track
  • Low-profile surface-mounted track to comply with seismic codes
  • Embedded seismic track
  • Flush with concrete floor (existing floor can be cut to create a trench for track assembly). Embedded aluminum track is coated to act as a barrier against oxidation caused by aluminum and fresh concrete
  • One-piece aluminum seismic track (easy to clean, rust-free)
  • One-piece aluminum seismic track
  • Seismic compliant
  • Rust-free
  • Easy to clean, because it does not collect debris or dirt. No need to insert a steel or stainless steel track.
  • Seismic track with a built-in anti-tip channel
  • Structurally sound one-piece seismic track with a sleek low profile
  • Low-profile seismic track
  • Prevents stepping hazards, allowing wheelchairs, carts, rolling harvest platforms, and forklifts to move around easily

Finding the right equipment partner the major key to building out your vertical farm facility


Why a trolley mobile system is better than a carriage mobile system for your mobile vertical farm.


  • Montel’s GREENRAK® mobile vertical grow rack systems cut back space-wasting aisles.
  • With one aisle and the same square footage, you double your growing capacity without having to move, acquire new land, expand, or build a new facility.
  • Maximize use of your available space to increase yields, free up room for your grow operation, or get rid of space you don't need to pay for.
  • The key to increasing your yield and profits is optimizing your grow space along both the horizontal and vertical axes, thus maximizing your cubic footage.
  • By using a mobile vertical grow rack system instead of static racking, you avoid lighting empty aisles without crops, thereby optimizing energy consumption. With its engineered gear ratios and high-quality components, GREENRAK® is the most durable and smoothest running mobile grow rack system on the market.

Once you give GREENRAK® a spin, you will never want to use conventional static rolling benches again

  • No wasted space between aisles means more square footage for growing horizontally.
  • Freedom to create aisles of 36” (91.44 cm) to 90” (2.29 m). Rolling benches average only about 24” (60.96 cm).
  • Optimized workflow, with better accessibility and more room to trim plants (ADA compliant).
  • Flexibility to move multiple mobile carriage units all at once versus the restriction of moving one stationary rolling bench fixed to the ground, which can usually roll only 8.5” (21.59 cm) from the center.
  • No need to bend over to move one or multiple mobile units SafeCrank handles are within arm’s reach and at hips level.
  • Each grow rack section is adjustable in height at 2” (51 mm) increments and can be sloped for better drainage with inclined tray supports.
  • SafeCrank aisle safety push-button and larger aisles are safer than, some conventional rolling benches with narrower aisles and no built-in safety measures.
