Wide Range
Now over 250 models and sizes, from 2 to 30 tonnes. Sheave sizes from 80 to 600 mm in diameter.
Multiple rope sizes and end fittings available.
Rugged
Johnson’s famous durability is well established in the industry. These blocks stand up to the toughest applications, whether in blistering sun or under icy blizzard conditions.
Reliable
From built-in strength comes the reliability long associated with the Johnson name. These blocks are performers, day after day and year after year. American quality you can count on.
Many Choices
Singles, doubles, top dead end, towing, oilfield, pipe laying and general construction. Sizes and specific models for all.
Convenient
Large, easy to grip hand nuts on all models, especially on the smallest models. Makes it easier to open and close under all conditions without removing gloves, and easy to tap with a hammer to loosen or lock down.
Secondary Securement
All hand nuts and shackles are fitted with ”R” pins as a secondary securement device, for example where inspection is limited or infrequent due to location or other factors.
