Frequently Asked Questions

The short answer to your question is “yes.” However, ASME B30.16 stipulates that when a system is comprised of components with different rated capacities, the rated load of the “system” shall be based on the lowest-rated individual component.

System is defined as the combination of Monorail, Hoist and Trolley in the case of a Monorail and Crane; Hoist and Trolley in the case of an Underhung Crane.

ASME B30.16-1.3.2 states that the supporting structure, including trolleys, monorail, or crane, shall be designed to withstand the loads and forces imposed by the hoist for the rated load.

1) Keep Load Close to the Ground

If the crane will be left with a load attached to it, the load should always be lowered as close to the ground as possible. Keeping tension on the cable will ensure it doesn’t swing or risk coming removed when it shouldn’t. Keeping the load high up in the air, however, invites problems with an accidental drop or other related issue.

2) Never Leave the Crane Powered On

The crane should never be left without an operator with the power left on. This would allow someone to come begin using the crane without proper training or authorization. In addition, when the crane is on it will typically be using the electric motor to maintain the cranes position. When the crane is turned off, it can use the hoist brakes, which is safer and also won’t put as much stress on the machine. This will also help to minimize the amount of electricity used, which will save the facility money.

Our Crane and Hoist division has certified technicians to provide monthly, quarterly or annual inspections. We will tag all of the equipment inspected and give a written report on each piece, with a quotation for repairing or replacing any unsafe equipment.

Yes, we have specific motor test equipment that will test the impedance, inductance, resistance, and phase angle, of the motor windings, performing a comparison of each to deduce if there are irregularities. This test will give us enough information in the field to know the internal health of your motor or if more extensive evaluation is necessary.

Without question. Zeller has the personal to determine if the issue is electrical, electronic, or mechanical. We not only find the problems but we can provide the solutions.

Most often yes. Depending on the horse power and the location it is usually more economical to have a Zeller technician come on site and perform this work. With specific information, Zeller can set a date to bring the necessary equipment and replacement bearings, and in most cases be in and out in one day. We will finish the job by providing the needed alignments and send documentation of the final readings.
