Wood catch is divided into: mechanical grasping wood, and rotary catch wood; wood without modification mechanical excavator grab piping and hydraulic systems can be used (low cost type); rotary catch wood need modification lines and hydraulic excavators system to meet the needs of 360-degree rotation (convenient, practical and cost-type) (1) mechanical grip wood; (2) 360 ° rotary hydraulic grab wood; (3) non-rotating hydraulic grab wood. 3 arrested Wood installation (1) Mechanical excavator grab Wood: The excavator bucket cylinder, driven by a hydraulic block and do not add another line; (2) 360 ° rotating hydraulic excavator grab wood: need to add two excavators sets of hydraulic valve blocks and piping to control; (3) non-rotating hydraulic excavator grab wood: the need to add a set of hydraulic excavators and piping to control valve block. 25-30 tons of non-rotating hydraulic rotary catch catch wood wood 2200 1200 1300 16MN + Hardox 31-35 tons of non-rotating hydraulic rotary catch catch wood wood 2300 1400 1520 16MN + Hardox 36-40 tons of non-rotating hydraulic rotary catch catch wood wood 24,001,650 1790 16MN + Hardox 41-45 tons of non-rotating hydraulic rotary catch catch wood wood 2500 1940 2100 16MN + Hardox 65 吨 not grab rotary hydraulic rotary catch wood wood 2900 3700 4000 16MN + Hardox Weight Title maximum opening (mm) Weight (KG ) Material Remarks 3-5 tons of wood and non-rotating rotary catch catch wood 1250 1250 380 420 Q345 + MN360 Q345 + MN360 6-10 tons of wood and non-rotating rotary catch catch wood 1450 1450 650 710 Q345 + MN360 Q345 + MN360 11-16 tons of rotation Wood does not swivel catch catch wood 1700 1700 800 870 Q345 + MN360 Q345 + MN360 17-20 tons of wood does not rotate the rotary catch catch wood 1900 1900 970 1050 Q345 + MN360 Q345 + MN360 21-24 tons of wood does not rotate the rotary catch catch wood 20,502,050 1070 1150 Q345 + MN360 Q345 + MN360 excavator long arm function and classification excavator long arm into the two-stage, three-stage, four-phase, longer sleeve arm. Two-stage mainly applied to earth and sand, concrete and other building transport, highways and river dredge dredging slope finishing and building foundation, rivers, deep groove and other earth excavating operation; three-stage, four-section mainly applies to high-rise building floor and other operations, such as the dismantling of the body; extended set arm: for dredging, berm. Such as the installation and removal is simple and convenient. Cheap, high efficiency, the excavator arm extension adapter sleeve lengthened up to 4 meters long arm excavator plus custom models explain the long arm of the operating parameters / parameter PC200-8 PC220-8 PC300LC-7 PC360-7 PC400-7 PC450 -7 arm size total length 15.4mm 18000mm 18000mm 20000mm 22000mm 24000mm Boom total length 8300mm 10000mm 10000mm 11000mm 12000mm 13000mm arm total length 7100mm 8000mm 8000mm 9000mm 10000mm 11000mm arm size of the total weight of 4000kg 4600kg 5200kg 6000kg 6500kg 7000kg configuration bucket capacity 0.4m3 0.4m3 0.5m3 0.6m3 0.6m3 0.7m3 maximum digging height 12510mm 13500mm 13720mm 14920mm 16100mm 17300mm Maximum digging radius 15100mm 17300mm 17600mm 19600mm 21600mm 23600mm maximum digging depth 11340mm 13000mm 13200mm 15000mm 16500mm 18000mm Transport height 2980mm 3160mm 3210mm 3210mm 3400mm 3400mm
