RIGGING LIGHTWEIGHT WATER PURIFIER (LWP) ON A 12-
FOOT, TYPE V PLATFORM FOR LOW-VELOCITY AIRDROP
DESCRIPTION OF LOAD
2-1. The lightweight water purifier (Figure 2-1) is rigged on a 12-foot, type V
platform. The lightweight water purifier consists of equipment as shown in Figure
2-1. The total weight of the lightweight water purifier is approximately 2,052
pounds. The total rigged weight of the load is 6,140 pounds. The load is 92 inches
high, 108 inches wide, 144 inches long, and the center of balance is 70 inches from
the front edge of the platform. Refer to FM 4-20.102/NAVSEA SS400-AB-MMO-
