Product details

• Manufactured in the USA to API-8C PSL-1 specifications with a minimum design temperature of -4°F (-20°C).
• The 70 Series has a spring loaded hook that is desirable for higher utilization and larger depths. The spring mitigates shock loadings and reduces wear on components.
• The 80 Series is not spring loaded and is desirable for shallow depths and rework.
• Utilizing the McKissick® revolutionary split nut retention system, these critical components: Are precision machined and individually fitted for maximum performance. Eliminate conventional threaded nut and potential problems associated with thread corrosion during regular maintenance.

• McKissick® API-8C sheaves are roll-forged and come equipped with flame hardened grooves for exceptional groove life. Each sheave is individually lubricated from easily accessible lubrication fittings located on the center pin. Equipped with double row tapered roller bearings and seals.
• The E-Z opening roll guards facilitate the fastest possible exposure of sheave cluster for quick reeving and contain no bolts to pull out and lose.
• Engineered for short overall length, extra weight, excellent balance for fast non-wobbling falls.
• Completely streamlined exterior surfaces with no unnecessary projections minimize opportunities for interference during operations.
