Anchorage height: 126.9m/174.9m/222.9m8. Type: Stationary, travelling, other types you needMain mechanism details1. Electrical mechanismOur company use France Schneider contactor, and tests each hoisting mechanism under no-load, static load, dynamic load, etc. To ensure the brake reliable, safe and durable.2. Hoist mechanismBrake wheel adopts cast steel materials, surface quenching and external circular, control the beating degree strictly. At the same time, also carrying on balance tests. Each hoisting mechanism is carrying on no-load, static load, dynamic load and so on, guarantee the reliability, safety and durableness.3. Derricking mechanismDerricking mechanism with free maintenance planetary reducer and cone brake motor, is well-knit in structure, stable and powerful in trolley, high endurance and low failure rate.4. Slewing mechanismSlewing motor adopts winding motor and hydraulic transmission. Slewing is stable and powering.5. Operation deviceCabin with humanized design, is convenient and comfortable, facilitate for safe driving.6. Mast sectionWelding process use high-strength wire. Main joints use special steel and special process.Rated hoisting moment (kN. m)4000Max hoisting moment (kN. m)4575Max height of hoisting (m)Stationary73Anchorages200Working Radius (m)Min Radius3.5Max Radius70Max hoisting capacity (t)Max height of hoisting≤ 100m25> 100m12.5QP2580HoistingFall24Lifting Weight /Speed (t/m/min)1/806.25/5312.5/402/4012.5/2725/13.5Power (kW)63BP110TrolleyingSpeed (m/min)0~100Power (kW)11HPW55B. 100SlewingSpeed (r/min)0~0.72Power (kW)3× 5.5ClimbingWorking Pressure (MPa)31.5Speed (m/min)0.46Counter-weightMax Working Radius (m)70605040Counter-weight (t)28.5241914.5Total Power (kW)90.5 (Excluding Climbing Mechanism)Design wind speed at the top of the crane (m/s)Climbing14In Service20Out Of Service0~20m3620~100m42100m~46Working Temperature (º C)-20~+40Main supply~380V/50HzRadius and Capacity70m jib(m)3.5~17.6182022252830(t)12.5(t)2524.3221.4818.1916.4614.3413.17(m)3335384043454850(t)12.512.0210.9310.309.468.978.307.90(t)11.6910.859.769.128.297.797.136.73(m)5355586063656870(t)7.377.046.596.325.955.725.405.20(t)6.195.875.425.154.774.544.224.0360m jib(m)3.5~17.9182022252830(t)12.5(t)2524.9322.0318.6716.8914.7313.53(m)3335384043454850(t)12.5012.3311.2110.579.719.208.528.12(t)12.0211.1610.049.398.538.037.356.94(m)53555860(t)7.577.236.786.50(t)6.396.065.605.3350m jib(m)3.5~18.1202225283033(t)12.5(t)2522.2418.8517.0614.8713.6712.14(m)35384043454850(t)12.4511.3210.679.809.298.618.20(t)11.2710.159.508.638.127.447.0340m jib(m)3.5~18.3202225283033(t)12.5(t)2522.5119.0817.2715.0613.8412.30(m)353840(t)12.511.4610.80(t)11.4210.299.63
