M. Spackman tion force equations for the basic scissor structure are derived separately for each load. DESIGN AND ANALYSIS OF AN AERIAL SCISSOR LIFT - AES JOURNALS
scissor jack is compile to lift low as well as heavy load with different conditions. The main purpose and significance The main purpose and significance of this paper is to design, optimize and standardize the current toggle jack to make the task easier and reliable. 4 1.1 Force and Stress Analysis The force analysis is based on the assumption that the scissor jack is loaded vertically symmetrical. Figure 3: Forces in Scissor Jack members The maximum capacity for the scissor jack is the 600 kg. Maximum Load = 600 kg, F= 600 kg * 9.81 𝑚 𝑠2 = 5886 N L= 145 mm, the length of the arms (From hole center to hole center) e = 180 mm, the length from base to
Design of Mechanical Hydraulic Jack K Abstract: - A jack is a device that uses force to lift heavy loads. The primary mechanism with which force is applied varies, depending on the specific type of jack, but is typically a screw thread or a hydraulic cylinder. Jacks can be categorized based on the type of force they employ: mechanical or hydraulic.
