What Are the Harrington RY Electric Wire Rope Hoists?
The RY Electric Wire Rope Trolley Hoists are designed to improve the following factors:
- Safety
- Reliability
- Performance
The Harrington RY Electric Wire Rope Hoists are ultra-low headroom trolley hoists with an H4 duty rating for high-demand applications. Each RY Electric Wire Rope Hoist comes standard with VFD controls for ultimate lifting and lowering accuracy.
The H4 duty rating means the Harrington RY Electric Wire Rope Hoists are designed for high-volume handling of heavy loads near rated capacity, specifically in the following fields:
- Steel warehousing
- Machining
- Foundries
The Harrington RY Electric Wire Rope Hoists comply with the following standards:
- NFPA 70 National Electric Code
- ASME B30.16 Overhead Underhung and Stationary Hoists
- ASME HST-4 Performance Standard for Overhead Electric Wire Rope Hoists
Harrington RY Electric Wire Rope Hoists in standard configurations (including certain options) are certified to UL 1340 “Standard for Hoist,” CSA 22.2 No. 33.
The Harrington RY Electric Wire Rope Hoists are able to handle your lifts up to 10 tons, depending on the type of hoist you purchase. There are four hoist models that come in capacities of 3, 5, 7.5 and 10 tons.
The 3 and 5-ton options can make lifts of 25’ and 33’, respectively. The 7.5-ton hoist can lift to heights of 30’, and the 10-ton model can go up to 40’.
What Is the Benefit of Having the Variable Frequency Drive (VFD)?
End-users can make adjustments to the speed of the VFD themselves.
As long as the workers making the adjustment have a man lift to get to the height of the hoist, they will be able to remove the control cover of the lifting device and make the change. The VFD is visible and easy to change.
What Is the Maintenance and Service Class for Harrington RY Electric Wire Rope Hoists?
Every box shipped containing a Harrington product will include an owner’s manual. The owner’s manual will tell end-users how to determine the maintenance schedule for each of their products along with other important information.
As the owner of the hoist, you have to figure out which of the following classifications apply to your applications:
- Normal Service
- Heavy Service
- Severe Service
Normal service is defined as operations with randomly distributed loads within the rated load limit or uniform loads less than 65% of the rated load limit for more than 25% of the time.
Heavy service is defined as operations within a working load limit which exceeds normal service. That is classified as hoists whose lifts exceed 65% of the rated load for more than 25% of the time or randomly distributed loads for over 25% of the time.
Severe service involves normal service and heavy service under abnormal operating conditions like weather or constant running.
Inspection Requirements
Once you determine what service classifications your hoists fall into, there are two kinds of inspections:
- Frequent inspection
- Periodic inspection
Frequent inspections are performed by an operator or other designated person at the facility:
- For normal service, frequent inspections would be needed monthly
- Under heavy service, weekly to monthly
- For severe service, daily to weekly
Periodic inspections are performed by designated persons. Harrington partners with Mazzella to provide these services. These inspections occur:
- At least yearly for normal service
- Semiannually, at least, for heavy service
- Quarterly for severe service
If you need your hoists repaired, you can contact Mazzella, which is a Harrington repair center, or speak with Harrington directly if you’re not sure who does repairs in your area.
By tracking the serial number of the product, Harrington can determine who the customer purchased the hoist from and guide you to that distributor first. If that company doesn’t do repairs, Harrington would put you in contact with a service repair center in your area.
What Are the Unique Features of the Harrington RY Electric Wire Rope Hoists?
