Asa multi-function machine, it can realize the quick switching of functions suchas cylinder pressurization, crowd winch pressurization, oscillator, CFA, anddual power head. Meet more different construction needs.
Thecapacity of rotary drive and main winch is increased by 20% and the workefficiency is higher
Therotary drive can be equipped with a torque multiplier (optional).The casingdrive torque is up to 360kN-m and the casing construction ability is stronger.
Themain and auxiliary winches both adopt single-layer rope technology. The servicelife of the wire rope is 2〜4 times longer thanthat of the multi-layer rope and the cost is lower.
Thedouble jib parallelogram luffing mechanism has a large support angle and a 16%increase in the support range. The operation a more stable.
Thehydraulic system adopts negative flow control technology which has a fastresponse and good control performance.
Theindependent high-power rate temperature-controlled hydraulic oil cooler issuitable for high-temperature construction and can adjust fan speed withtemperature changes.
Intelligentcontrol system can automatically adjust and display the verticality of mast,automatically slew and slag discharge, CFA model automatically lifting concretepouring and pile type display. The system uses bus panel design to preventmisoperation.
