SELECTING THE RIGHT HYDRAULIC SET-UP

Step 1 Choose a hydraulic cylinder that suits the application best. What you need to consider: 1. How many cylinders are required for this application? What push or pull tonnage is required per cylinder? Note: always choose a cylinder with a tonnage rating of 20% or more than what is required. 2. Does the cylinder need to be massive or hollow? 3. Which stroke is required? 4. Does the cylinder need to fit within limited-clearance work areas? What are the installation dimensions? 5. Must the cylinder push, pull or both?  - Single-acting cylinders push - Double-acting cylinders push and pull 6. Is the weight of the cylinder important and affecting material choice: steel or aluminium? • Cylinders with swivel caps are available if the cylinder needs to withstand off-center loads. (JLLC series,  NSSS 10, 25 ton) • Locking collars are available if the lifted load needs to be supported for longer periods of time. Step 2 Choose a hydraulic pump, that matches the selected cylinder, consider: 1. Do you prefer a hand, foot, air, or electric powered pump? 2. How much oil capacity is required? (= oil capacity x no. of cylinders) 3. How fast must the pump be? 4. What is the frequency of the application? 5. Single-acting or double-acting? 6. Is the weight of the pump important? 7. Available air or electric supply? Step 3 Choose necessary hydraulic accessories, consider: 1. Required hose length and number 2. Coupling sets for coupling and uncoupling 3. Pressure gauge with T-adapter 4. Manifolds 5. Extra hydraulic oil
