Telescoping jacks are adjustable steel poles that feature mechanical telescopes to extend twice their shortest length for easier fitting into different spaces. Furthermore, there are air relief ports designed to drain off excess air pressure and decrease any bouncy rides.
An elevator system with a car movable between floors requires dynamic sensors to detect when its telescoping jacks become misaligning and become out-of-sync.
Early Life and Education
Jack was raised in an auto-industry town of Indiana as part of a deeply religious extended family who met regularly for worship services, prayer meetings and Sunday school sessions. These experiences instilled him with strong values such as hard work, faithfulness and service to others.
Vanderbilt Divinity School was his choice, where he studied church history and religious education. His experiences in civil rights movements as well as those fighting for peace and justice helped develop his interest in interfaith religious education.
Some telescoping jacks are non-synchronized (pistons rise at their own rate), while others feature internal synchronization enabled by control valve and oil that transfers from lower piston(s) to upper piston(s) chamber. This latter design offers better ride quality.
Telescoping jacks have proven themselves essential tools in solving many problems associated with elevators, including its unique functionality and design. Their synchronized design ensures all pistons lift or lower at once to eliminate a bouncy ride; furthermore, their compact length takes up minimal space when in retracted mode.
No matter your elevator modernization needs, hole-less telescoping jacks provide the most cost-effective solution. Before selecting one for installation on an elevator platform or hoistway wall, it is essential that its size allows for vertical alignment with both.
Use these formulas to calculate actual overhead available:
Telescoping jacks provide solutions for elevator applications with complicated space requirements, modernization or new construction designs that necessitate complex space requirements, holes being drilled or ropes, governors or safeties being necessary. They have the added advantage of eliminating holes being drilled while eliminating ropes, governors or safeties being needed as additional safety features.
This jack design utilizes internal synchronization (all pistons rise at once), achieved via oil transferred from an intermediate cylinder to the inner plunger of each telescoping unit. Furthermore, there are air relief ports installed to help alleviate air pockets that might otherwise lead to an uncomfortable ride.
Dynamic sensors on two seal housings (20) pass through both an intermediate cylinder and inner plunger during elevator operation, and detect any differences in height of telescoping jacks; when detected they trigger a resynchronization demand to the controller to halt an out-of-sync condition that would require stopping of cars for inspection.
Telescoping jacks are hydraulic jacks designed to deliver long output travel from an extremely compact retracted length. As with all hydraulic tools, special care must be taken in selecting ground conditions and the jacking point on a vehicle for best results when extended – as well as to ensure stability when extended.
Non-synchronized telescoping jacks have the drawback of offering an unstable ride, which can be remedied by draining all air from its cylinder via air relief ports, then repacking its pistons.
Synchronized designs of all telescoping jacks ensure that all stages raise and lower at once, creating a smoother, more stable ride than non-synchronized designs that allow each stage to act independently from others. Furthermore, this provides safer operation in case of failure – including leakage or seepage issues that cause bouncy rides.
