750mm cfa auger for soilmec sr65 drill rig

CFA auger od750mm with soilmec cfa coupling xhd5 used on soilmec sr65 rig for Continuous Flight Auger pile Continuous Flight Auger (CFA) mode with a 750 mm diameter auger represents a standard, high-efficiency setup for medium-to-large deep foundation piling.Technical Details for a 750 mm CFA Auger Tooling When selecting or operating a 750 mm auger stem on the SR-65, the following tooling configurations are standard: 1. Joint & Hex Connection Hex Joint Sizes: Typically standard SW 150 or SW 200 heavy-duty drive hexes with dual retaining safety pins. Hollow Stem ID: Inner concrete delivery tube is usually 100mm to 125 mm 4" - 5" inside diameter to allow high-volume concrete pumping without excessive line pressure. 2. Cutting Head & Teeth Selection Soft to Medium Soils (Clays, Silts, Sands): Flat teeth / bullet teeth combination with a standard pilot bit. Hard Clay / Dense Gravel / Weathered Rock: Heavy-duty round shank carbide bullet teeth (e.g., 25 mm or 38/30 mm shanks) for aggressive penetration. Bottom Plug: Flap-type or lost-cap/knock-out plug fitted at the tip to prevent soil ingress into the hollow stem during drilling. 3. Star Cleaners & Guides Auger Cleaner: Hydraulic star/rotary cleaner mounted near the bottom of the mast, sized specifically for 750flighting to clear spoil during extraction. Auger Guide: Lower mast guide inserts matched to 750 outer diameter to maintain verticality during collar drilling A 750 mm Continuous Flight Auger (CFA) string equipped with Soilmec XHD5 hex couplings is a high-torque continuous auger setup commonly deployed on medium-to-large Soilmec rigs (such as the SF-55, SF-65, SF-70, SR-65, or SR-70)Technical Specifications Overview Drilling Diameter : 750 mm Coupling Connection: Soilmec XHD5 (Extra Heavy Duty 5-inch) Drive Type: 190 mm Hexagonal tapered male/female joint with 2 quick-lock safety pins Internal Concrete Shaft (Hollow Stem ID): 125 mm 5 inch) nominal bore for pumping high-slump concrete or grout Stem Construction: Heavy-wall / double-wall central steel tube designed to absorb high torsional stress () without collar deformation Structural & Design Features 1. Central Stem & Flights Main Tube: Typically heavy-duty structural tube (e.g., ST52 / S355 steel, approx. 203mm to 219 mm OD with 20-40 mm wall thickness depending on depth rating). Flighting: Pitch: Optimized for spoil evacuation while maintaining flight strength. Thickness: 16-20mm main flights, with thicker lead flights (25-30mm) at the starter section. Wear Protection: Hard-faced welding on flight outer edges or tungsten-carbide strip inserts. 2. XHD5 Hex Coupling Pin Lock System: Dual transverse safety pins prevent accidental decoupling during rotation or reverse extraction. Sealing: Internal O-ring seals at the tapered joint prevent grout/concrete leakage under pumping pressures 3. Lead Auger / Starter Head Options Clay / Medium Soil: Fitted with flat teeth Hard Ground / Weathered Rock: Fitted with round shank chisel picks (e.g., B47K / B43H holders). Bottom Valve: Spring-loaded or disposable knock-out plug at the concrete outlet bit. 1,SPECIFICATION OF CFA AUGER NO D/mm L/m /mm P/ mm d1/mm d2/mm T/ mm HEX /kg 600 CFA AUGER 3 125 500 245*25 140*7.5 20 XHD5 860 6 125 500 245*25 140*7.5 20 XHD5 1590 600 CFA AUGER 2 125 500/600 245*25 140*7.5 20/30 XHD5 620 750 CFA AUGER 3 125 500 245*25 140*7.5 20 XHD5 1020 6 125 500 245*25 140*7.5 20 XHD5 1910 750 CFA AUGER HEAD 2 125 500/600 245*25 140*7.5 20/30 XHD5 750 Chí Minh cfa auger match soilmec cfa rig, Vancouver cfa auger match soilmec cfa rig,Calgary,toronto ,Ottawa Montreal ,Quebec ,canada Mexico cfa auger match soilmec cfa rig Belize cfa auger ,Puerto Rico cfa auger match soilmec cfa rig Guatemala cfa auger match soilmec cfa rigSan salvador cfa auger match soilmec cfa rig Honduras CFA AUGER ,Nicaragua CFA AUGER Costa Rica cfa auger match soilmec cfa rig,Dominicana cfa auger match soilmec cfa rig Santo Domingo/Panamá cfa auger Bogotá cfa auger match soilmec cfa rig Colombia Medellín cfa auger match soilmec cfa rig,Barranquilla/Cartagena/Cali Ecuador cfa auger match soilmec cfa rig Peru lima ,callao cfa auger match soilmec cfa rig Bolivia cfa auger match soilmec cfa rig Chile Santiago de Chile Argentina/Uruguay/Paraguay cfa auger match soilmec cfa rig Brasil/Guyana cfa auger match soilmec cfa rig /Usa Los Angeles/new york/California cfa auger New Zealand/Auckland cfa auger match soilmec cfa rig Australia Adelaide/Melbourne/Sydney/Brisbane cfa auger match soilmec cfa rig thailand Malaysia ,Singapore cfa auger match soilmec cfa rig, Indonesia/Jakarta/Pilipinas cfa auger match soilmec cfa rig, Россия/ruusia cfa auger match soilmec cfa rig, O`zbekiston//Монгол Улс cfa auger match soilmec cfa rig, South Africa/Tanzania/Portugal/spain/România cfa auger match soilmec cfa rigTianjin huachang xingye technology co ltd
