Frequently asked questions
Common questions about JARKE from 3G Electric.
What is the difference between a JARKE cantilever rack starter kit and an add-on kit?
A JARKE starter kit includes the upright column and base needed to begin a rack row, and it can stand alone. An add-on kit is designed to attach to an existing starter unit to extend the row, so it does not duplicate the base structure. In practice, you buy one starter for each row and as many add-on units as needed to reach the required storage length. Starter and add-on units must match in upright height and base depth so the arms align across the row. When ordering, confirm the manufacturer part number prefix: starter kits and add-on kits use different prefixes for the same nominal dimensions.
How does the pin-lock design on JARKE heavy-duty cantilever racks work?
On JARKE heavy-duty pin-lock cantilever racks, arms connect to the upright through a pin-lock arrangement rather than bolts. This allows the arm elevation to be changed without tools, so storage levels can be adjusted when the load profile changes. The pin-lock connection is used on the heavy-duty line; medium-duty JARKE cantilever racks use a bolt-on arm connection instead. Pin-lock arms are typically selected where arm positions are expected to change or where heavier loads are handled. As with any cantilever rack, the arm capacity and upright capacity must be checked against the actual load before the rack is loaded.
What load types are JARKE cantilever racks intended for?
JARKE cantilever racks are intended for long, bulky, or irregularly shaped items that are difficult to store on standard pallet racking. Typical loads include pipe, lumber, steel bar, tubing, and similar stock. The open-front, single-side support design lets loads be placed and retrieved from the aisle with a forklift or other handling equipment. Straight arms suit flat or uniformly stacked loads, while inclined arms help hold cylindrical items in place. Load length, weight, and the number of storage levels determine the required arm length, upright height, and base depth.
What dimensions are available in JARKE heavy-duty pin-lock cantilever rack kits?
JARKE heavy-duty pin-lock cantilever rack kits are supplied in a range of upright heights, base depths, and widths. Examples in the line include 96 in, 10 ft, and 12 ft upright heights, with base depths from 40 in to 81 1/2 in and widths around 74 3/4 in to 81 1/2 in. Both starter and add-on kits are available in these sizes, and both single-sided and double-sided configurations exist. Because dimensions are tied to load length and aisle requirements, the upright height, base depth, and arm length should be selected together rather than independently.
Can JARKE cantilever rack rows be extended or repaired with individual components?
Yes. JARKE cantilever rack is a component system, so an existing row can be extended by adding compatible add-on units, and individual arms, uprights, or bases can be replaced. The key requirement is that added components match the existing upright height, base depth, and arm style so that arms align and the row remains structurally consistent. When extending a row, confirm the manufacturer part number of the existing units and select add-on kits with the same nominal dimensions. Mixing heavy-duty pin-lock and medium-duty bolt-on components in the same row is not appropriate because the arm connection types differ.
How does 3G Electric support buyers of JARKE cantilever rack systems?
3G Electric supplies JARKE cantilever rack kits and components and supports buyers in matching starter and add-on units, arm styles, and upright dimensions to their load type and storage layout. Because cantilever rack is configured rather than bought as a single stock item, this includes confirming that the selected kit dimensions and arm configuration are compatible with the intended load and handling method before order. 3G Electric ships globally, so buyers can source JARKE cantilever rack regardless of region. For procurement and maintenance teams, providing load length, load weight, required aisle width, and the number of storage levels helps narrow the correct kit.
