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® 2.0 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® 2.0 is the most durable and smoothest running mobile grow rack system on the market.

Montel’s GREENRAK® 2.0 mechanical-assist mobile system is designed for high-density vertical multi-level indoor farming of leafy greens, micro greens, cannabis or any other controlled environment agriculture.


  • Rails: Made of aluminum bars up to 144” long and secured to the floor with stainless steel concrete screws. Levelness of floor to be 1/2” maximum variation within 10’.
  • Wheels: Made of a proprietary glass-filled nylon that is resistant to water and most chemical solvents. They have good abrasion and compression resistance and they won’t flat spot. They have an operating temperature of -45° to +350° Fahrenheit.
  • Bearings: All wheel bearings are stainless steel ball bearings.
  • Wheel Shafts: All shafts are made of stainless steel.
  • Wheel Channels: Made of steel and are powder coated. Formed to be easy to clean. Capacity of 2,400lbs per section.
  • No Side Members: Wheel channels are linked at their center to create a free space for the workers shoes on both sides of the mobile.
  • Drive Tube: Tubular drive shafts are made of 1.315'' (33.4mm) outside diameter by 1.045'' (26.5mm) inside diameter powder coated steel tubing. Each end is sealed.
  • Handle Knobs: Are made of durable phenolic with a smooth finish.
  • Sealed Column: Column is made of an outer polymer shell sealing inside components from dirt and water splashes.
  • Hardware: All hardware is made of stainless steel.
  • GROWRAKTM 2.0: Grow rack system is made of powder coated galvanized steel. Refer to TDS M01.165.011 for details.


Once you give GREENRAK® 2.0 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.
