  1. Introduction: For this contest, I wanted to model a piece of hydraulic equipment that uses a manual pumping action to manipulate the hydraulics. This would give the Technic model a natural look and feel when using the manual hand pump to activate the pneumatic cylinder(s). After much thought and searching, I landed on a hydraulic scissor lift cart. This piece of equipment will require the three main components of the Technic pneumatics system, should be compact requiring interesting mechanisms utilizing the pneumatics, and has a added bonus of being something that is rarely modeled (are there any others?) hopefully making this contest entry slightly unique! Here are some pictures I will use for my inspiration: Plan: I plan to break this model into four distinct builds: General Frame, including caster wheels and handle bar for pushing cart. Scissor lift mechanism to raise and lower the cart table using a pneumatic cylinder. Foot pump mechanism that uses the manual pneumatic hand pump to cause the pneumatic cylinder to extract. Hand brake lever mechanism that moves the pneumatic switch to cause the pneumatic cylinder to retract (based on gravity, not air pressure). Anticipated Challenges: Keeping the mechanics of all the pneumatics into a low profile so that the cart table is a low as possible when all the way down. The sliding mechanism of the scissor lift. I am not sure how to best model this and keep everything stable and strong. Translating the vertical foot pump action to a horizontal stroke that is strong and long enough to depress the pneumatic hand pump while keeping it low profile. Operating the pneumatic switch located in the cart base via a lever on the handle bar. I am currently thinking that this might be good use of the flex system! Issue here will be having enough travel to successfully move the switch far enough. Also need the mechanism to include a spring to return the lever back to initial position. Build: Part 1: General Frame Here is my initial prototype to set a standard for size and to use as a base for the different mechanisms. Part 2: Scissor Mechanism Part 3: Foot Pump Mechanism Part 3: Hand Lever Mechanism Final Model: Video:
