Boom & Sticks
F&L works with a technician team that has participated in OEM boom & stick projects of Kobelco®. We know which part of the product takes more force during operation, and we design the structure scientifically, have strict standards of steel material & thickness for each part. When the boom & stick set is in standard size (i.e., not long reach etc.), all hoses and oil pipes used are purchased from OEM supplier. Also, we have rich project experience in manufacturing large boom & stick, including CAT385, PC800 and ZX870.
Material: Q345B & Q690D etc. They are with good mechanical properties, perform well in wear resistance, welding performance, atmospheric corrosion resistance and low temperature impact toughness.
Production: At F&L, we use advanced Gantry CNC plasma cutting machine, large boring machines, specific machines of lathe, press & bending, all together ensuring high process accuracy. Also, instead of carbon dioxide, liquid argon is used as welding gas, which is with higher stability of electric arc, ensuring higher quality of welding shape and strength.
Treatment: Hydraulic tubes all go through pickling phosphating treatment, keeping the tubes clean, reducing any chances of rusts inside pipes which may danger the hydraulic pump and cylinder. Also, boom & stick are sandblasted, so welding concentration is effectively eliminated.
