BVA Hydraulics HLN-5502 Lock Nut, High Tonnage, Hydraulic Jacking Cylinders
BVA Hydraulics HLN Series lock nut style of high tonnage, hydraulic jacking cylinders are offered in varying capacities and stroke amounts through 30 models and up to 300 tons capacity.
An engineered plunger thread and mating lock nut serve to create mechanical load-holding quality for added safety in any lifting project. With scheduled time-outs, the lock nut can be screwed down against the cylinder body offering engineered load support.
HLN-5502 models are shown and are equipped with optional CVMS3, manually operated, load-holding check valves. In the closed position, flow/pressure is allowed into the cylinder, checking any reverse flow. In the open (retract) position, this CVMS3 valve allows free flow in both directions.
Incorporating load-holding check valves and lock-nut style cylinders into a high-tonnage jacking system provides a much greater level of safety quality.
All BVA Hydraulics Cylinders are designed, manufactured, and tested in compliance with ASME B30.1.
Confidence Built on Quality ASME B30.1 ANSI B40.1 SAE 100 BVA Hydraulics products are manufactured through an International Quality Assurance System, ISO 9001 which involves consistent observation of administration, management, manufacturing, and production control. Under this system, the related operations are monitored in all aspects from the purchase order to the assembly line and through to shipping the order. The cylinders comply with load testing requirements and/or the safety factor for material yield strength while still functioning properly without oil leakage. BVA pressure gauges meet the criteria for grade A. BVA hydraulic hoses comply with the Material Handling Institute’s specification of minimum life cycles and minimum burst pressure rating. Products comply with the industry standards defined by ISO 9001
