Introduction:
Tower crane is used to lift, lower and horizontally move materials in construction and other industry. It has large lifting capacity and lifting height, wide moving range, and can rotate. It basically consists of base foundation, mast, slewing unit, working jib, counter jib, counterweight, hook, and operating cabin.
Features:
1. All the components are designed to minimize the total number of trucks required to transport. The jib components can house the jib ties to make transport easier and quicker.
2. With the factory-performed pre-reeving and the auxiliary winch supplied as standard, assembly of the jib and counter-jib ties can be carried out quickly and in total safety.
3. The mechanisms are always used at full power. When hoisting, the speed is optimized according to the load and command used. In distribution, progressive variation of speedand the maximum speed are adapted to the weight of the load. In orientation, there is controlled proportionalspeed with optimal acceleration and deceleration in accordance with the maximum admissible torque for the mast.
4. DVF Distribution
The jib-footDVF mechanism is easily accessible in total safety.
Progressive speed variation by proportional control.
The speed depends directly on the controls manipulated by the crane operator.
To make driving the crane easier, 2 hard spots integrated into the controlsprovide better pinpointing of the speed.
5. RVF + orientation
The RVF Optima + orientation enables gentle rotating movements without jerking.
Fully integrated progressive control.
Driving adapts to the behavior of the crane operator:
The slow-down phase of the jib is managed by the frequency variator.
Or by an inverted command in the slow-down phase, called a "counter-orientation" command.
As a result, the crane operator can control stoppage.
