Heavy-Duty Mobile Racking
Spacesaver’s ActivRAC® Mobilized Storage System eliminates idle aisles by mounting pallet racking or shelving onto mobile carriages that move along rails. These carriages have a load capacity of 3,000 to 30,000 lbs. and are fitted with a host of safety and security features to support safe and effective workflows.

Optimizing Warehouse Operations
With the ever-increasing cost per cube to both develop and lease commercial warehousing space, Spacesaver’s heavy-duty, high-density mobile racking systems are an ideal solution for warehouses, cold storage facilities, and any location looking to store more heavy items in less footprint. In addition, the ability to anchor our systems to existing concrete makes them a cost-effective solution for increasing capacity in any space, without the need for renovation or expansion.

Benefits of Heavy-Duty Mobile Racking
- Enhanced capacity to support increased height and weight requirements when compared with Standard High-Density Mobile Shelving systems
- Improved workflows and access to materials by allowing users to store and categorize items more effectively
- Reduced need to add square footage to facility footprint as the system helps organizations avoid costly renovations and expansions
