Wacker trowels change blade speed without mechanical adjustment

Wacker recently expanded its ride-on trowel line by adding two new models. The 36-inch CRT 36-24A-H weighs 765 pounds and is powered by a 24-horsepower Honda engine. The CRT 48-31V-H is a 1,035-pound unit with a 48-inch blade. It features two five-blade rotors and two spray retardant nozzles. Both of hese models feature a torque converter clutch design that allows the operator to change the trowel’s blade speed to match concrete conditions without mechanical adjustments. During slower, floating operations where pans are needed, the blades can be set into a non-overlapping position. During the finishing process, the blades can be reset to the overlapping position for a complete, smooth finish. The blade pitch is adjustable up to 25 degrees.

Wacker’s 36- and 48-inch walk-behind trowels offer the speed and performance of a ride-on unit thanks to a constant variable transmission system. This transmission delivers rotor speeds from 20 to 170 rpms without the use of special speed adjustment kits or installation downtime. All Wacker walk-behind trowels are powered by Honda gas engines. The company’s AVT models feature a standard twist-pitch control, while the AVP units feature Wacker’s patented Pro-Shift pitch control system to allow the operator to easily and instantly change blade pitch.

In March, Wacker announced it was introducing a new worldwide truss screed that would comply with worldwide CE standards. These two new lines of vibratory truss screeds are equipped with enhanced protective guards that fully enclose the exciter and belt to eliminate exposure to fast-moving parts and reduce the chance of injury. Both the W- and V-Series truss screeds can be joined to form spans in various lengths ranging from 2 1/2 to 10 feet.
