DESIGN & MATERIAL
The container consists of a steel frame, floor crossmembers, side walls of corrugated steel, front wall, rear wall, wooden floor and 8 corner fittings. The floor consists of beech plywood panels treated according to Australian Health Requirements. All outer welds including the base frame welds are continuous. The welds ensure strength and watertightness. The inner side of the lap welds is provided with sealant.
FRONT END FRAME
The front end corner posts are produced of one pressed piece of carbon steel gauge 6 mm. The front end header is made of steel, thickness 4 mm. The front end sill is of steel, thickness 4 mm. The front end panel is vertically trapeze corrugated and is made of steel, thickness 2 mm.
The door frame corner posts are produced of two pieces of special open box profile of carbon steel, thickness 6 mm, pressed to make an open profile for the outer part and of carbon steel thickness 6 mm U-profile for the inner part. The rear top header consists of two pieces, the upper part is of steel, thickness 4 mm and the U profile is steel thickness 4 mm. The rear top header and the rear sill are reinforced with steel strips in the area where the locking gear parts are welded on.
Corner fittings are produced in accordance with ISO R 1161 and are approved by a classification Society.
The base frame consists of:
- two bottom siderails gauge 4 mm of steel formed to an open profile
- C-profile crossmembers of steel thickness 4 mm
- two fork lift tunnels. The upper plate of the fork lift tunnel is of steel thickness 4 mm, the side walls of the fork lift tunnel are of. steel, thickness 4 mm, the bottom strap is of steel thickness 6 mm.
The dimensions of the fork lift tunnels are in accordance with ISO standards.
Side walls consist of
- top rail dimension 50 x 12 mm
- bottom side rail made of . steel, thickness 4.5 mm.
- side panels made of steel gauge 2.0 mm, vertically trapeze corrugated. The panels are welded to each other and overlap welded to the corner post.
The roof consists of 2.0 mm steel, horizontally die pressed.
The roof has a 6 mm upward camber. The roof panels are butt welded and are continuously welded to the side top rails and to the front header and to the door frame header top plate.
4 corner gussets of steel thickness 4 mm are provided around each corner fitting.
The floor consists of 28 mm plywood chemically treated to prevent infestation in accordance with the requirements of Commonwealth of Australia Department of Health or 3 mm antiskid steel floor fully welded.
The floor is fastened to the cross-members by galvanized screws, shank diameter 6.3 mm, countersunk about 1.5-2 mm below the surface of the floor.10 screws per cross-member.
The perimeter of the floor is sealed with a caulking sealant.
The horizontally corrugated door panel is made of 2.0 mm . steel. Further it consists of a frame made of closed profiles 110 x 40 x 3 mm and horizontal U profiles of steel thickness 3 mm. Each door wing is suspended on 4 hinges and can be swung not less than 270 degrees. To hold the door open, each wing is provided with a nylon rope door holder and with a hook on the bottom side rail. The right hand wing is designed to prevent the left hand wing from opening when the container is sealed according to TIR requirements.
J- shape door gaskets are made of EPDM. The gaskets are fastened to the door by stainless steel strips and rustproof rivets. 5 rivets on top and bottom gasket. Lower gaskets and vertical gaskets 50 cm from bottom sealed with sealant.
The hinges are fitted with stainless steel pins and nylon bushings. The locking gear is WISTRA model M3481 - 2 pieces. One rod on the right wing is fastened to the door by three AVDEL type bolts. The rest of the connection are by means of heavy duty galvanized bolts, nuts and washers.
Three lashing bars are welded inside each front corner post. Along the top and bottom side rail there are 2 + 2 lashing fittings on each side of the container, each located in a recess. The lashing fittings are designed to withhold a 1500 kg pull load without deformation to the lashing fitting and the surrounding area.
One plastic ventilator cover is provided on each side wall of the container between the corrugations close to the front /one ventilator at front, the other at rear/.
All welding shall be carried out using the MAG-M process in Argon shield gas mixture / 82 % Argon, 18 % CO2 /. All welders are skilled and qualified and have passed the required examinations for the specific welding technique. All welds shall be free of porosity, cracks, slag, spatter and wire ends. For critical welds strength calculations will be provided upon Buyers request.
