KONECRANES ULTRA ROBUST 16 TONNE FORKLIFT SPEEDS UP OPERATIONS FOR LEADING BRICK MANUFACTURER

Concrete looks uniformly grey – but is very diverse. At the construction site, it is either used in liquid form or delivered as a finished element. Wöhrl Ziegel & Fertigteile produces precast concrete and brick elements up to 9 meters long with a stacking weight of up to 16 tons. After manufacturing, the elements are transported to the external warehouse and to transport trucks on double-T beams. To ensure that they survive their journey without damage, they need a particularly sensitive and robust heavy-duty lift truck that can transport large and small loads safely, even in dusty environments. Konecranes designed a heavy-duty lift truck that is a precise match for these challenging conditions.

 

Heavy Duty Lift Truck with Flexible Fork

Wöhrl Ziegelwerk-Deckensysteme GmbH manufactures ceiling elements, balconies and special components for a wide range of applications. The stacking packages weigh from 3 to 16 tons and can be up to 9 meters long. “To ensure their products arrive at the construction site undamaged, they must be transported carefully,” explains Thomas Wöhrl, Managing Director and owner of Wöhrl Ziegelwerk-Deckensysteme GmbH. “That’s why we are putting them on a double T-beam.” The beams are then lifted by the heavy-duty lift truck and transported to their storage location. On the one hand, the lift truck has to be very robust because concrete dust from the works and the external warehouse is deposited on and in the hydraulic system. At the same time, sensitivity and flexibility are required: In order to fit optimally into the beams, the tines of the heavy-duty lift truck require a special shape. Thomas Wöhrl: “The fork must also be expandable so that the truck can safely pick up large parts.”

That’s why Konecranes has equipped the SMV 16-1200 C heavy-duty lift truck with a fork extension and tines with a special groove. “This means that the tines are a perfect match with the double-T beams,” says Uwe Höss, Sales Manager at Konecranes Lifttrucks Germany. “The fork can be extended to a width of up to 4 meters, and the tines can be moved individually to the left or right with hydraulics.” This allows the operator to pick up the double T-beams even when the approach is not at the perfect angle – with conventional forks, the lift truck has to reset and reposition. The new machine with a wheelbase of 3.75 meters lifts the precast element packages weighing up to 16 tons to a maximum height of 4 meters.

 

A Precise and Durable Forklift

“When large concrete elements are stacked high, the operator must have good visibility and be able to work precisely,” stresses Uwe Höss. “Thanks to a camera directly at the top of the mast, the operator can always see where the fork is directed, even at a height of four meters.” The truck is also equipped with an inching pedal. Uwe Höss: “When the operator steps on the brake, the traction drive is disconnected from the on-board hydraulics and full power is available to the hoisting system.” This allows the lift truck to maneuver safely with heavy loads.

 

In the concrete and brick plant of Wöhrl Ziegel & Fertigteile, the hydraulics of the heavy-duty lift truck must be particularly robust and withstand aggressive concrete dust. The solution from the Konecranes experts: A HLL (Hydraulic Longlife) microfilter system collects particles as small as 3 µm – more than four times as fine as normal filters. This significantly extends the oil change interval from 4,000 to up to 12,000 hours. This reduces the maintenance requirements and increases the operating time of the lift truck.

 

Robust, Safe and Comfortable Lifting of Concrete Elements

Our operators work long hours. With the Optima cab from Konecranes, they have a clear view and a pleasant working environment. The vibration- and noise-reduced cab is equipped with an air-suspended seat – the latest in ergonomics. A color screen also gives the operator a constant view of the mast and rear-view camera images. “Here in Berghaselbach, all machines have to withstand harsh conditions and work safely,” says Thomas Wöhrl. “The heavy-duty lift truck with high-performance filter system specially designed for our requirements by Konecranes will certainly be operating in our concrete plant for a long time to come.”
