One-touch inspection doors from Tsubaki

New range of inspection doors and hatch covers designed for use with bulk material conveyors

TSUBAKI have launched a range of one-touch inspection doors or hatch covers for use with conveyor systems, particularly those transporting bulk materials such as aggregates.

The door is intended for installation on chutes, hoppers, covered conveyors and other material-handling plant and equipment. It has a simple lever lock mechanism that can be opened one-handed to allow inspection or access for cleaning.

Each door unit is fitted with high-performance gaskets that provide a dust-tight seal and also serve to keep rain at bay in outdoor installations. A choice of gasket materials is available to suit different application needs: polyethylene foam, neoprene rubber, heat resistant etc.

Performance of the doors over time is ensured by the rigidity of the frame, which is designed to maintain its shape throughout its working life. Two styles are offered, regular and high neck.

The former design is designed to be compact; the latter is taller and raises the door up so is suitable for installation on curved surfaces, when extra space is required to accommodate insulating material and other special cases.

Both styles are available with a variety of door options, including solid, windowed, pressure-resistant, flanged and with a screen. They are also available in three corrosion-resistant series, P series (standard), Q series (corrosion resistant), and R series (all stainless steel).

There is also a special version with a key lock option, which could also be used as a safety feature, restricting access to potentially dangerous machinery to authorized personnel only.

The doors are available in a range of sizes from 50mm x 80mm to 100mm x 170mm.
