Product Name: China Building Equipment Hydraulic Tower Crane Hammer Head Tower Crane Hammered Tower Crane Qtz315 (TC7040) Model NO.: QTZ315 (TC7040) Type: Top-Slewing Crane Moving Type: Fixed Installation: Jack-Up Maximum Lifting Weight: >10t Maximum Lifting Height: 200-250m Condition: New Certification: CE, ISO9001 Trademark: CHICO Transport Package: 40hq Specification: 16T Origin: Shandong HS Code: 84262000 Product Description TOPKIT TOWER CRANE 7040-16TFeatures of flat top tower cranesFor even higher performance and greater operational options: With its modular jib and without tie bars, the topless crane saves time and money.The advantages of a modular jib without tie-bars:Lower overall height(mutiple crane sites)Easy jib erection and dismantlingJib configuration can be easily modified as the works proceed, can be erected and or dismantled "in the air", section by sectionNever before has there been a crane that is so easy and quick to erect in total safetyHoisting and trolley ropes installed on the ground, plug-in connections for electrical equipment and safety devices, time-saving factory assembly of cabVariable frequency slewing, continuously variable speed control by means of a stepless controller, that also adapts to the crane operator's drving style.Variable frequency hoisting, speed continuously adjusted and optimised according to the load being handled, very slow speeds, smooth speed changes, high productivity.The masts adopt the standard bases, allowing it to be adjusted to the desired heightThe adjustable bases provide a choice of method of installation-on fixing angles-on cross-shaped base-on travelling gearOr as a climbing craneMain parametersprojectunitParameter valuesMax.lifting load2 Times Multiplyingt84 Times
