Cantilever Racks: Capacity Guide

Rack load capacity is determined by evaluating the required load per arm, load distribution, arm spacing, column configuration, bracing, base anchoring, and the facility conditions. Cantilever racks should be assessed as a complete engineered system rather than by arm rating alone. RackUSA provides engineering services including structural load analysis to help establish an appropriate configuration.

Typical capacity varies by the selected cantilever rack configuration and the material being stored. The available system is specified for 500 kg to several tons per arm, with the final rating determined by engineering and manufacturer recommendations. Long, bulky products should be distributed correctly across the arms, and operators should follow the approved load limits.

Cantilever rack dimensions are not limited to one standard size in the available product information. Height and width are customisable to accommodate the stored load, while adjustable arms support different material sizes. RackUSA can help determine suitable dimensions based on product length, weight, handling equipment, available floor space, and whether single- or double-sided storage is required.

Cantilever racks are designed for long, bulky, and irregularly shaped products, including pipes, beams, profiles, bars, lumber, furniture, and sheets. Their open-access design supports easier loading and unloading, while adjustable arms accommodate different load sizes. Forklifts and cranes are compatible handling options, subject to the system design and applicable operating procedures.

Single-sided cantilever racks provide storage access from one side and can be positioned against a wall or facility boundary. Double-sided systems provide access from both sides and can increase storage flexibility in open warehouse areas. The appropriate configuration depends on available floor space, material flow, handling equipment, and the desired access arrangement.

Do not exceed the manufacturer’s recommended weight capacity per arm. Base anchors are required to secure the rack to the floor and help prevent tipping, while horizontal and diagonal bracing support the structure. Regular inspections should cover bases, arms, screws, and other structural components. RackUSA also offers safety audits, repair, and maintenance support.
