A-Series Aluminum Gantry Crane 13
Promise to Perform Industries, Inc.
MAINTENANCE
1. A system inspection should be performed 30 days after installation. All nuts, bolts, and screws should be checked for
tightness. All end stops, cotter pins, and hoist trolleys should be checked for abnormal wear or breakage.
2. A complete inspection of all fasteners and connections should be performed annually or every two thousand (2,000)
hours. Heavy conditions of use may require more frequent inspections.
3. Operators should visually inspect the system before each use to note any unusual or abnormal system operations.
4. If the system fails ANY inspection point on any of the inspection checklists, immediately remove the system
from service and call Spanco at 800-869-2080 for instructions.
5. Download and print additional blank inspection checklists from the literature tab at Spanco.com.
LOAD TEST
After the A-Series Aluminum Gantry Crane has been installed, OSHA requires a load test before operating and after any
modifications. This equipment is designed and manufactured to the rated capacity marked on the equipment with due
allowances for safety factors. Prior to initial use of the Gantry Crane, a person appointed by the owner, under the direction
of a qualified technical person, must perform a load test at 125 percent of the rated capacity using certified test weights. See
CMAA 78 for periodic load testing requirements. Under no conditions shall the rated capacity be exceeded during regular use
or during annual or semi-annual load tests.
DESIGN FACTORS
Nameplate capacities represent the rated load on the hoist hook. The load rating of a hoist shall not exceed the nameplate
capacity. Spanco’s design includes an allowance of 15 percent of nameplate capacity for trolley and hoist deadweight and
25 percent of the nameplate capacity for impact. This design provides a margin to allow for variations in material properties,
operating conditions, and design assumptions. No crane should ever be loaded beyond its rated capacity.
SERVICE FACTOR
All Spanco gantry cranes are designed for moderate usage (Class C Normal/Industrial service) as defined by CMAA 70:
• System or equipment is used where lifted loads average 50 percent of the rated capacity with five to 10 lifts per hour,
averaging 15 feet, not over 50 percent of the lifts at rated capacity.
Applications involving vacuums, magnets, or other high-impact lifters are considered severe usage and require special design
considerations. Contact Spanco for special design pricing.
Consult Spanco for usage other than moderate and all instances of high cycle rates or high-impact applications, such as high-
speed air or electric hoists, vacuum lifters, or magnets.
