## FULLY FOLDED mode of COMPACT HYDRAULIC JACK ENGINE CRANE HOIST LIFTING
The fully folded mode refers to a specific, non-operational configuration of a compact hydraulic jack engine crane hoist/lifting device. This configuration is engineered to minimize the equipment's physical footprint, primarily for purposes of storage, transport, and space optimization. Such devices are typically used for lifting and maneuvering heavy objects, particularly vehicle engines, transmissions, or similar components, within workshops, garages, or industrial settings where space may be limited.
In the fully folded mode, the primary structural components of the crane are collapsed, retracted, or disassembled into a significantly smaller and more manageable form compared to their operational state. The exact mechanism varies between models and manufacturers, but common elements involved in achieving the fully folded state include:
1. Boom Retraction and Positioning: The extendable lifting boom (jib arm) is typically retracted to its shortest possible length. It is then pivoted downwards and/or horizontally until it lies parallel or close to the main vertical support column or frame of the crane. In some designs, it may be secured with pins or latches to prevent movement.
2. Leg Folding: The splayed support legs, which form the base and provide stability during lifting operations, are folded inward. This usually involves pivoting them upwards or sideways so they lie parallel to the main vertical column. Folding the legs drastically reduces the width and length of the crane's base. Locking pins or mechanisms secure the legs in the folded position.
3. Hydraulic Ram and Pump: The hydraulic cylinder (ram) that provides the lifting power is usually fully retracted. While not typically folded itself, its position relative to the boom may be adjusted or secured. The pump handle, if detachable, might be removed or secured alongside the frame; if integrated, it is typically positioned flat or secured.
4. Hoist Mechanism and Hook: Any chain, cable, or hook associated with the hoist is secured to prevent tangling or snagging during storage or transport.
The primary benefit of the fully folded mode is the substantial reduction in the space required for storage. A compact engine crane that might occupy several square meters when splayed for operation can be reduced to a relatively narrow, upright structure, allowing it to be stored against a wall, in a corner, or within a smaller storage area. This mode also greatly simplifies transportation, making the crane easier to load into vehicles or move between different locations within a facility.
It is crucial to understand that the fully folded mode is solely for storage and transport; the crane is non-functional, lacks stability, and must never be used for lifting or supporting loads in this configuration. Transitioning from the folded mode to the operational mode requires extending the legs, positioning and potentially extending the boom, and ensuring all locking mechanisms are correctly engaged according to the manufacturer's instructions before any lifting attempt is made.
