Building Construction Machine Rotary Drilling Rig

HW crawler rotary drilling rig is widely used in the construction of bored piles and holes in urban high-rise buildings, railways, highways, bridges, airports, ports and other pile foundation projects. It has wide application range, high construction efficiency, stable performance and service. Thoughtful, environmentally friendly and energy saving advantages. Various performance display and safety monitoring and alarm devices, convenient transfer and shifting, 360-degree free rotation, compared with large rotary drilling rigs, low cost of purchase, low transportation cost, high efficiency, high profit, high integration of drill pipe and main machine, No need to disassemble, save time, oil and electricity (optional), reduce costs. Rotary drilling rig is a construction machine suitable for hole forming in building foundation engineering. It is mainly suitable for soil layer construction such as sand, cohesive soil and silty soil, in cast-in-place piles, continuous walls, foundation reinforcement, etc. Widely used in a variety of foundation construction, the rated power of rotary drilling rig is generally 125~450kW, the power output torque is 120~400kN·m, the maximum hole diameter can reach 1.5, and the maximum hole depth is 12-15. Meet the requirements of all types of large-scale foundation construction.   Parameter / ModelHW150HW200HW260HW350DimensionsWorking state (length × width ×height)m5.9×2.3×10.57.1×2.6×128×2.8×11.58.8×2.8×12.8Transportation status (length ×width × height)m8.2×2.3×3.2510×2.6×3.3810×2.8×3.5512.8×3.0×3.65Overall weightt17twenty two2628Maximum drilling diameterMm1200140014001400Maximum drilling depthm15202535engineBrandYuchaiCumminsCumminsCumminsmodel4A115Z6BT5.9-C1506BTAA5.9-C2056BTAA5.9-C205rated powerKw/rpm86/2400110/2300153/2000153/2000Hydraulic flowWorking pressureMain pumpMpa30303030Secondary pumpMpa////Maximum flowMain pumpL/min2×632×632×802×80Secondary pumpL/min////Power HeadMaximum torqueKn.m6080100130Rotating speedRpm5-905-855-855-60Maximum throwing speedRpm90858560Pressurized systemMaximum pressureKn50707080Maximum lifting forceKn608080100Maximum travelMm2800280028002800Main hoistMaximum lifting forceKn10151518Maximum lifting speedm/min72717168Deputy hoistMaximum lifting forceKn15203045Maximum lifting speedm/min60707075MastTilt left and right°±5±5±5±5Anterior angle°8888ChassisMaximum walking speedKm/h4333Maximum grade°35353030Track widthMm500600600600Track chain pitchMm154190190190Chassis lengthMm3600380042004500Average grounding ratiokPa66.3778592This is large diameter hole drilling machine, more and more popular in Foundation engineering construction.Pls contact Kelly to Know more details: + 86 13665372568   /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
