The handling of cooled or frozen food puts high demands on the temperature chain. The Crawford inflatable dock shelters provide the optimal sealing of temperature controlled premises during the loading and unloading process. Contrary to other types of dock shelters, the vehicle does not push towards the shelter. Instead, the shelter is inflated around the docked vehicle, providing complete sealing. The Crawford inflatable shelters are suitable for all vehicle sizes and their sealing capacity exceeds by far the standard normally required by operators.Unbroken cold chain!The food industry puts high demands on loading bay sealing in order to keep the cold chain as intact as possible. The dock shelter must provide continuous weather protection throughout the entire loading and unloading operation. Like a glove, the Crawford inflatable dock shelters tighten around the vehicle, preventing air inlet. Customer demands are fulfilled!Rolling top seal for large variations in vehicle heightA special inflatable shelter model has been developed in order to cope with large variations in vehicle height. The top seal is a roller design automatically activated for low or high vehicles. In addition, it follows all vertical movements of the docked vehicle, continuously providing high tightness.Simplified dock-in navigationIn rest position, the inflatable dock shelter is completely retracted behind the side structures, giving the vehicle driver the possibility to use the complete width of the loading bay when reversing into it. In addition, yellow front line indicators further facilitate dock-in navigation. Stable collision protectors at ramp height prevent shelter damages.Insulated top and side panelsThe inflatable dock shelter is installed into a frame construction covered by insulated panels, giving additional insulation effects. The design facilitates easy and fast component exchange, should this be needed.Special ground model for no-ramp applicationsNormally, dock shelters are installed at dock level, but sometimes a loading ramp is not available. For such applications, a special model of the Crawford inflatable dock shelter is supplied, giving the same high tightness around the entire door opening all the way down to ground level.High quality material compositionThe side and top inflatable airbags are made of impact resistant material with a strong, woven core. It is non-flammable, color stable and highly resistant to weather impacts in other words a material well suited for optimal function in rough docking environments.Useful option Crawford 670 SIB & Crawford 671 SIR- Wear Shield Extra layer of PVC curtain mounted to side bags by VELCRO tape to cover the lowest part left and right in the vehicle contact area. When the vehicle moves up and down during loading/unloading the side bags are protected against damages. Improved sealing and less draught into the building.Technical data 670 SIB & 671 SIR Nominal width 3600 mm Nominal Height 3555, 3755, 4055, 4355 mm Top bag stroke SIB 1000, 1300 mm Top rollo stroke SIR 2200 mm Side bag stroke 650 mm Nominal depth 770, 1000 mm Wall & roof material 40 mm insulated panel Front guide lines Yellow polyethylene plastic Fan 230 V, 1-phase, 50 Hz, 250 W Noise Nieveau 65 dBA in working position Fabric Quality Top bag SIB 0,6 mm PVC, 650 g/m² Top curtain SIR 0,6 mm PVC, 650 g/m² Side bag 0,6 mm PVC, 680 g/m² Option wear shield 3 mm pvc, 3400 g/m²
