mlk and hlk series air chain hoist 1/4 ­ 6 metric ton lifting capacity features the mlk family of hoists is suitable for a5/h5 severe duty use in the 1/4 1 metric ton range the mlk is designed to be used as a high speed production hoist the mlks is ideal for slow speed spotting the hlk series uses many of the same components as the mlk family of hoists the hlk family incorporates a larger chain wheel to accomodate 3/8 in diameter chain and a lower gear ratio to handle increased load capacities hlk series hoists range from 1 through 6 metric tons and are severe duty rated refer to trolley specifications section for plain geared and motorized trolleys spark-resistant features mlkr and hlkr spark-resistant hoists have been designed to give maximum protection in explosive or other hazardous environments components for spark-resistance are as follows · bronze hooks · bronze trolley wheels · stainless steel one part reeving or aluminum two part reeving lower hook blocks · aluminum stop ring 1/4 ton models · stainless steel load chain · stainless steel pendent levers and bronze valve caps · spark-resistant pull chains the load capacity and speeds of mlkr and hlkr units are reduced a restricted motor is used to accomplish this as stainless steel chain is not hardened and strength is less than standard alloy chain refer to trolley section for plain geared and motorized trolley specifications all mlk and hlk specifications model no ml250k ks kr ml500k ks ml500kr ml1000k ks hl1000k kr hl1500k capacity metric tons lbs 1 4 1 2 1 2 no of chain falls 1 1 2 2 1 1 2 2 3 4 weight per foot of lift lbs 0.56 0.56 1.12 1.12 1.3 1.3 2.6 2.6 3.9 5.2 -2a 1 top lug lbs 48 48 61 61 86 86 125 125 184 234 -2c 1 top hook lbs 48 48 61 61 84 84 125 125 193 248 -2d 1 rigid trolley lbs 68 68 81 81 106 164 203 203 392 442 -2f 1 geared trolley lbs 71 71 84 84 109 167 206 206 395 445 -3h air trolley lbs 78 78 91 91 116 174 213 213 402 452 550 1100 1100 2200 2200 3300 4400 6600 10000 13200 1 1 1 1 2 2 3 4 1 2 6 air chain hoists hl2000k hl3000k hl4500k hl6000k notes all weights are for model with 10 feet of lift and pendent 1 pull chain control deduct 3 lbs where noted 24
