ASME A17.1 code requirements for minimum rated capacity are as follows:
Class A	(General Freight Loading) – 50 lbs. per sq. ft.
Class B	(Motor Vehicle Loading) – 30 lbs. per sq. ft.
Class C-1	(Industrial Truck Loading – truck carried by elevator) – 50 lbs. per sq. ft., but not less than load, including weight of truck.
Class C-2	(Industrial Truck Loading – truck is normally used for loading and unloading only, and is not usually carried by elevator) – for elevators of 20,000 lbs. capacity or less capacity shall equal the weight of the loaded truck – maximum load on platform during loading and unloading not exceed 150% of rated load.
Class C-3	(Other loading with heavy concentrations where truck is not usually used) – 50 lbs. per sq. ft., but not less than load.
NOTE: Square feet area of platform is determined by net inside area.

Application Summary

This application is used when a side opening is required in addition to a front opening. The rails and brackets are located on one wall of the hoistway. Please note that the dimensions shown are only two examples of applications possible. Please call MEI for job-specific dimensions.

Advantages

Accommodates front and side openings.
No extensive pit or overhead is required.
Available for both low and high capacity cars.

Disadvantages

Since the rail brackets are all mounted on one wall, additional rail force accommodations may be necessary.
Oil contamination in the ground is possible. As a precaution, the jack can be enclosed in PVC pipe. Areas with frequent seismic activity will have the greatest risk of oil contamination.
The jack must go down into the ground roughly the same distance as the desired travel. Drilling a jack hole is expensive and may be nearly impossible in certain structural or geologic conditions.
