Frequently asked questions

The Prorunner 12 is designed in accordance with Directive 2006/42/EC and Directive 2014/30/EU. With a focus on person safety. The belt is oversized with a safety factor greater than 4, minimizing the risk of belt failure.

In the unlikely event of a belt failure, no person should be present within the safety zone.

If the belt fails, the motor will continue to rotate and initiate braking. At that point, the automatic locking device will engage.

For the PR12, the use of the automatic locking device is not mandatory, as each carrier is equipped with two belts. The likelihood of both belts failing simultaneously is extremely low.

Belt is steel enforced and 50mm wide, which would give that the max. toothed belt load (safety factor >4) is 7,680N and breaking load 26,870N per belt. The PR12 is equipped with two belts so we can double this number.

Maximum weight of HD carrier + conveyor + product is 360kg. With an acceleration of 2m/s^2 and gravity 10m/s^2 that gives a maximum force of 4,320N.

Max. toothed belt load of the PR12 is therefore a total of 15,360N (whereby the safety factor is already >4) of which we will go up to 4,320N. (approx. 30% of the indicated max. toothed belt load and approx. 8% of the breaking load).

Hereby: If one of the PR12 belts breaks, the other can catch it. The carrier will then not fall down immediately.

The thickness of the powder coating must be at least between 60µm and 90µm per layer. With a primer and a topcoat, the thickness is at least 120-180µm.

When having an EPD coating, an extra 18-25µm is added.

Actuators that Qimarox use without UL/CSA classification, are underneath the 100VA and are thereby usable when using a Class 2 Power Supply and/or is secured with for example product number 9000-41042-0100400 of Murr Electronics.

Yes, this is a standard option which can be used when the infeed side of the products is the same side as the outfeed side of the products.

The machines are not suitable for temperatures above 40 degrees Celsius. Its components have not been rated or classified for use in such high-temperature environments. Operating the machine beyond this limit may lead to performance issues, accelerated wear, or component failure. For applications requiring higher temperature resistance, get in touch with Qimarox.

The machines are not available in a hygienic version. It has not been designed or constructed to meet the specific requirements necessary for hygienic applications. As alternative we can supply a stainless steel version and for the Prorunner mk5 a Wash Down version is available.

The machines can be configured in multiple variants for use in moisture environments or when the machines are cleaned with water. To ensure durability and performance, materials and protective coatings resistant to corrosion are essential. Proper selection of components, such as EPD coating, stainless steel or the Wash Down variant, can prevent material degradation.

The machines can be configured in multiple variants for use in environments involving saltwater exposure. To ensure durability and performance, materials and protective coatings resistant to corrosion are essential. Proper selection of components, such as stainless steel or EPD coating, can prevent material degradation. For applications requiring salt water resistance, get in touch with Qimarox.

The machines can be supplied without the inclusion of zinc material. If desired, alternative materials or coatings can be used based on specific requirements. For applications requiring no zinc parts, get in touch with Qimarox.

The machines are not designed for cleanroom use.

The machines can be used in dusty environments. It is crucial to adhere to the prescribed maintenance schedule to ensure optimal performance and longevity. Dust accumulation can impair functionality, leading to increased wear and potential failure. Regular maintenance helps prevent these issues, safeguarding operational efficiency and reducing downtime. Compliance with the maintenance plan is essential for sustained reliability and safety. Please note that the machine can not be used in ATEX environments.

The machines has not been tested or calculated for seismic regions. Structural integrity under seismic loads is unverified. Design modifications or anchoring may be necessary for compliance and safety. Until then, operate with caution in high-seismic-risk areas.

EPD coating is a pretreatment before powder coating, which makes the coating more resistant to e.g. moisture environments.

Yes, the machine can be supplied with EPD (KTL) coating.

The machine needs to be anchored to the floor, see documentation. Above 4 meters height the machine also needs to be anchored every 4 meters to a solid structure for sideways stabilization.

This depends on the motor and the customer’s preference. We use brake voltage 400V AC as standard.

This is to increase the friction between the rollers and the product. This allows, for example, plastic crates (which slide easily) to be transported more effectively. It can also reduce the noise level when ‘harder’ products are transported.

No, this machine does not use pneumatics.

Yes, this is possible. However, the lift needs to be recalculated to see if the gear motor still meets the requirements. It might be needed to equip the machine with a new gear motor. Always consult Qimarox for changes.

Yes, it is possible. The conveyor must fall within the specifications of the vertical conveyor (see specifications).

It is possible. When the products are placed side by side, it is important that they are properly centered and guided during insertion. When the products are placed one behind the other, it must be taken into account that a gap may occur between the products if there is a difference in speed between the feeding and infeed conveyor. Possible solution is to use a 2-zone conveyor.

In all cases, it is important that the center of mass of the total combination of products rests approximately in the middle of the conveyor.

Hereby: If one of the PR12 belts breaks, the other can catch it. The carrier will then not fall down immediately.

To know if this is possible we need to have more information on the I/O module to use so we can check if it can be mounted on the same location as our standard unit or if we need to make changes to the design. In every situation additional cost can apply and it may also effect delivery time. Preferred is to stick with the standaard options supplied by Qimarox.

Leaving the unit out will also generate additional cost as it would require a change request. Ask your sales representatives for the possibilities.

This depends on the motor and the customer’s preference. We use brake voltage 400V AC as standard.

This is to increase the friction between the rollers and the product. This allows, for example, plastic crates (which slide easily) to be transported more effectively.

All our vertical conveyors are fully electrical. However, some add-ons such as tilting conveyors or stoppers (e.g. in a bypass conveyor) require pneumatics.

No, this lift does not contain pneumatics.

The machines are not suitable for ATEX environments. It has not been designed or certified for use in explosive atmospheres as defined by ATEX standards.

The Prorunner vertical conveyors always carry the CE certificate from Qimarox. When the system integrator incorporates the lift into a larger system, they must issue a CE certificate for the entire system to ensure overall compliance.

By not using a counter weight it’s possible to have more flexibility for your lay-out as pallets can go in and out in each direction. Anther factor is cost, on engineering, material and maintenance. For each different application the weight would be different and by adding moving parts maintenance becomes more expensive. Also the counter weight would need safety pins for person safety when entering the safety zone.

All these additional costs will not compensate the slightly higher cost of a stronger gear motor.

Yes, We can deliver this machine in the RAL colour of your choice.

Please check with your sales representative the implications on cost and delivery time.

No, our vertical conveyors are designed to work within an automated conveyor system.

Yes this is possible but we strongly advise you to make use of our experienced technicians on site (ask our sales department for the options in your region). If this is not possible Qimarox supplies the assembly instructions.

Yes, the Prorunner mk1, PR2 and PR12 are available with an electric or pneumatic actuated safety pin.

This is not possible. Limit switches are included in the standard design of the machines, because of safety regulations these can’t be removed.
