Many accidents or equipment damage happens when operators dont fully understand the equipment. (beta), the gain or amplification factor of a transistor, normally is given when solving a circuit equation. Therefore, the maximum horizontal outreach provided by the upper boom is typically less than the single boom of a straight lift. Terrainability Refers to a machines ability to negotiate terrain. Type 3 MEWPs can travel elevated and is controlled from the platform. 0 Reach diagrams are published in the manual of each machine to give operators a visual understanding of the limits of the machine. The working envelope of a boom lift includes all combinations of accessible height and outreach of the platform. li li Pli General Employees with powered access or fork lift training will be used where required to operate either MEWPs or FLTS Auxiliary Functions Lift functions that are operated by another power source than the main source (used primarily in situations to return the operator to the ground when the main power source is depleted or does not function). The MEWP must not be positioned against another object to steady the platform. Mobile Elevating Work Platform (MEWP) intended to move persons to working positions where they are carrying out work from the work . object more heavier at the bottom is more stable than one heavier at top. The maximum height of the topmost platform is 3.5 times the minimum dimension of the base. Narrow models are generally heavier, due to increased counterweight. as turate rotates location of fulcrum changes. The relative stability of the folded versus the denatured depends on the environment of the protein. Likewise, the position of maximum backward instability occurs when the tower is lowered to a near horizontal angle while keeping the upper boom raised at the max angle. Function Test Pre-operation test of all aerial work platform functions performed by a qualified operator prior to each use (refer to the previous section on safety). iii.
