4-6 LIFT CHAINS AND SLIDE BLOCKS
WARNING
Do not operate a unit on which any chain assembly is damaged or in need of re-
placement. Operating a unit with a damaged chain can cause severe injury or
death to personnel and damage to equipment.
Inspect all lift chains every 6 months. Inspect for signs of wear, split leaves, loose pins,
clevis damage, and elongation. Replace any chain that is damaged in any way. Chain as-
semblies may be ordered from your dealer or direct from the factory. Do not operate a
unit on which any chain assembly is damaged and in need of replacement.
Chain Elongation Inspection
Refer to Figure 4-11. Measure 20 pitches of chain. Twenty pitches of new chain should
measure 12.5 in. (31.75 cm). Replace the chain if a 20-pitch length measures over 12.75
in. (32.385 cm).
