Smooth running of used fat disposalRollers of the LPA-PATH series by Blickle optimise kitchen components for restaurant equipment suppliers in the USAFor the disposal of used fat from deep fryers, restaurateurs often use moveable containers to quickly replace the used material. In the USA, it was just this process that caused a restaurant supplier quite a headache. Particularly in this kind of environment, the quick replacement of containers is necessary so as not to interrupt the operation for an unnecessarily long time. Contaminations and aggressive cleaning chemicals impaired or fairly quickly blocked the steering behaviour of castors that were attached to the oil containers. As a result the customer incurred considerable costs. The people responsible got in touch with the experienced Blickle team in the USA – and laid the facts on the table. The customer wanted castors from a local supplier that worked in a reliable manner and were resistant to both oil and cleaning agents. Furthermore, the customer required short delivery times in order to reduce the freight and repair costs. “We looked at the application on site and suggested the LPA-PATH 50K-FK type castors. "Our partner was able to test them extensively and was extremely satisfied with the results”, stated Manual Kraibühler, international sales manager at Blickle.

Advantages of the LPA-PATH 50K-FK castor
Blickle developed the series as a swivel castor with a mounting plate. It also has a bracket made of pressed steel. The special dynamic Blickle riveting of the swivel head makes for minimal play with ease of operation and high durability. The wheel is made of high-quality, thermoplastic polyurethane for low-noise operation with low roll and swivel resistance, even in oily environments. In everyday practice it protects the floor and does not cause wear. Users can easily work with it in temperature ranges from minus 25 to plus 70 degrees Celsius.

No additional costs

LPA-PATH is firmly bonded and exceptionally durably connected to the wheel centre. This ensures low wear and tear. The Blickle development can move loads up to 75 kilograms. The high-grade materials make the wheel resistant to the most common cleaning agents as well as frying oil in gastronomy. Blickle matched the hole pattern of the mounting plate to the customer's previous solution. As a result, there were no design changes or additional tooling costs. Furthermore, the Blickle engineers designed a new castor based on the basic body of the original solution. The modified bracket now has a special fork width and the thread guard was also redesigned. Reward of the efforts: The NSF certified the series. The LPA-PATH series now complies with all the regulations and received approval from the National Sanitation Foundation (NSF) of the USA.

Worthwhile investment
Investing in the Blickle development paid off for the restaurant equipment supplier. Premature blockages or failures of the castors are a thing of the past. The grease trap containers can be easily and smoothly replaced without splashing used fat. The castors are easy to operate in oily environments and can be steered without any problems. They also survive regular cleaning with aggressive media unscathed. The LPA-PATH series ensures that burgers, fries and schnitzels from the deep fryer are quickly served to consumers without delay.

Vibration-free rotation, even under heavy loadsHeavy duty drive roller with Blickle Extrathane® polyurethane tread STHN 620x1000/180-1000-937434The customer... is a Danish company which was established in 2005. The company provides a wide variety of solutions for the wind power industry, e.g. welding systems and handling facilities for the manufacture of turbine towers and other wind power components.
The challengeWind turbine towers are manufactured by cutting steel plates into segments, rolling them and welding them together. Turbine towers weigh around 1,000 tonnes. During the welding process, the tubular segments are placed on rotators which turn the individual segments so that the parts can be welded together.

In the past, steel wheels were used as rotators due to the high load bearing requirements. The rigid steel wheels caused vibrations during the rotation of the tower, which had a negative impact on the weld seams. This was down to the poor surface quality and lack of roundness in the bent tubular sections.

To combat the vibrations, manufacturers began using wheels with steel wheel centres or cast wheel centres and a polyurethane tread. In order to achieve the required load capacity, at least two wheels were required on an axle. As the weight of the tubular segments increased, the required load capacity could only be achieved by placing four wheels next to one another. The disadvantage of this design is that placing four wheels next to one another puts an enormous load on the axle. Because of this, a significant axle diameter is required to prevent the failure of the axle. The customer was looking for a new solution with only one polyurethane wheel in order to cut material costs and achieve even higher load capacities.


Our solutionBlickle’s engineers worked closely with the customer to develop a roller with a load capacity of 100 tonnes - an improvement of 25 per cent compared to using four individual wheels. The stable steel wheel centre is reinforced with two centre bars in the interior of the roller body. The special shape of the wheel centre distributes the load in the vicinity of the bearing locations on the outside of the wheel unit, significantly reducing the amount of stress in the wheel axle. This allows the customer to reduce the axle diameter and reduce its material costs while increasing the load capacity of the unit.

The polyurethane tread is cast onto the stable steel wheel centre using a specialised rotating casting procedure.
The resultThe Blickle solution provides increased load capacity and improved safety. The rollers are also significantly less complicated to install than multiple individual wheels. The way in which the forces are distributed makes it possible to use a thinner wheel axle, cutting costs significantly.

A number of facilities have already been equipped with the heavy duty rollers and successfully tested. The new Blickle solution will be used as the standard option in future.
 Product advantages and technical information STHN 620x1000/180-1000-937434:• Very high load capacity of 100 tonnes per roller• Optimal distribution of forces over the wheel axle makes it possible to reduce the axle diameter
