All operators and support personnel shall read and fully understand manufacturer furnished operator’s manual, the latest applicable American National Standards Institute (ANSI) Safety Standards for Cranes, and any applicable federal, state, or local safety regulations before operating machine. Crane and load ratings comply with ANSI and Power Crane & Shovel Association (PCSA) Standards.
ALL “ON OUTRIGGER” lifts shall be made with outrigger beams fully extended and jacks extended to fully support and level machine.
Underlined ratings are based on machine’s structural strength. All other ratings do not exceed 85% of tipping load on rail and 80% of tipping on outriggers with machine stable on firm ground.
DO NOT EXCEED crane load ratings. When load radius or boom angle are between listed values, use the smaller load ratings. DO NOT ATTEMPT TO TIP MACHINE TO DETERMINE ALLOWABLE LOADS.
Weight of hook blocks, buckets, slings, and all other load handling devices are not accounted for in the load chart. The load handling device must be considered as part of the load.
Reduce ratings appropriately for wind conditions, speed of operation, soft or uneven supporting surfaces, etc.
Load ratings apply to this machine ONLY as originally manufactured and equipped. Unauthorized modification or optional equipment may reduce load capacity. Please consult LITTLE GIANT before modification or use of optional equipment not covered on this chart.
These load ratings are for lift service only. Consult & adhere to appropriate load ratings chart for other applications (clamshell, dragline, magnet, etc.)
