Loading Dock Shelters

Cronax Loading Dock Shelters are designed to provide a protective seal between the warehouse and truck, ensuring safe, efficient, and weatherproof loading and unloading operations. Built with durable, high-quality fabrics and reinforced frames, they deliver long-lasting performance in the most demanding logistics environments.

By sealing the gap between the dock and trailer, Cronax Dock Shelters prevent the entry of dust, rain, wind, and pests, while also reducing energy loss in temperature-controlled facilities. This ensures better product safety and improved working conditions.

Available in rigid-frame, retractable, and inflatable models, the shelters adapt to different vehicle sizes and docking conditions. The heavy-duty, wear-resistant fabric and flexible design withstand repeated trailer contact without damage.

CUSTOMIZATION OPTIONS

Shelter Type	Retractable or fixed-frame loading dock shelter designed to create a sealed interface between building and vehicle, reducing air leakage, weather exposure, and energy loss.
Primary Application	Distribution centers, cold storage warehouses, food & pharma facilities, retail supply docks, and high-volume logistic hubs requiring energy efficiency and environmental protection.
Maximum Clear Opening	Accommodates trailer widths from 2,300 mm to 3,000 mm and heights up to 4,500 mm; custom sizes available to match site-specific dock designs.
Operating Range	Vertical sealing range typically ±500 mm to ±700 mm above/below dock height to handle a wide variety of vehicle sizes.
Sealing Efficiency	Engineered to provide up to 90–95% seal efficiency, minimizing dust ingress, outside air infiltration, and conditioned air loss.
Construction	Heavy-duty galvanized steel frame with collapsible/retractable arms, covered in high-tensile PVC-coated polyester fabric or reinforced vinyl flaps.
Curtain / Head Pad Design	Side curtains reinforced with abrasion-resistant wear pleats; top head curtain or head pad adaptable to varying truck heights.
Wind & Impact Resistance	Retractable frame flexes upon trailer impact to reduce damage; structural wind resistance up to 120 km/h depending on model.
Compliance & Standards	Conforms to international building codes, fire-retardant fabric standards, and energy efficiency guidelines (EN, IS, ANSI).

Operation	Passive system — no motor or drive system required. Shelter activates when vehicle reverses into dock and compresses/seals against curtains or pads.
Control Integration	Can be interlocked with dock leveler and door controls, ensuring dock shelter is engaged prior to door opening for maximum energy savings.
User Interaction	No manual operation required; optional adjustable head curtain or inflatable models may include pneumatic controls.
Safety Systems	Impact-resistant steel frame with spring-return retractable arms prevents damage during vehicle misalignment; flame-retardant curtain materials enhance fire safety.
Emergency Function	Shelter frame automatically retracts if excessive force is applied, preventing permanent structural damage.
Integration	Compatible with dock levelers, vehicle restraints, high-speed doors, and building management systems for complete dock automation.

Fabric Options	Standard 900 g/m² PVC-coated fabric; optional heavy-duty reinforced vinyl or woven polyester for high-cycle applications.
Frame Finish	Hot-dip galvanized or epoxy-coated steel frame for long-term corrosion resistance; stainless steel available for hygiene-sensitive environments.
Color Options	Standard black side curtains with contrasting guide stripes; custom RAL color finishes available on request.
Seal Options	Available in fixed pad, retractable curtain, or inflatable cushion models depending on site requirements.
Weather Protection	Integrated rainwater channel, top canopies, and wind-resistant side seals to prevent rain and dust ingress.
Branding	Custom printing available on curtain faces for corporate logos and facility branding.
Accessories	Optional guide lights, bumpers, dock shelters with translucent roof panels, and LED loading area illumination.
