Ring Climbing Cylinders

Holmatro Ring Climbing Cylinders provide incremental lifting heights of up to nearly 36”, much more than a traditional hydraulic cylinder. Starting at under 12” retracted, each portable, ergonomic cylinder has a lifting capacity of up to 100 tons but weighs only 50 pounds and features a compact footprint. Its innovative design eliminates the need for stacking wood or filler blocks which expedites the lifting process. With the addition of a Split Flow Pump the operator can safely and accurately lift, lower and hold a load in place with all points synchronized. Engineered Rigging has Ring Climbing Cylinders in our bare rental fleet. As an authorized Holmatro distributor, we also sell new systems.

How a ring climbing cylinder works.

How Does A Ring Climbing Cylinder Work?

Instead of relying on external cribbing built up manually around a traditional jack, the ring climber system incorporates aluminum stacking rings that become part of the cylinder assembly. As the cylinder extends to the end of its stroke, a technician inserts lightweight stacking rings (around 2.2 lbs. each) around the cylinder rod, between the load and the top of the cylinder housing. The rings are engineered to precise specifications and have a documented load rating. They lock into position to create a stable, predictable, load-bearing column. This innovative, ergonomic design eliminates the need to stack cribbing wood, which expedites the lifting process, optimizes accuracy and improves safety. Operators find it much safer and efficient to stack rings, not wood.
