Double Cylinder Rectangular Core Jacks Capacity
Rectangular core jacks with double cylinders are among the most widely used tools in the world for lifting and rigging tasks. They consist of two springs and a single-stage telescoping cylinder mechanism which canchange its length in discrete increments up to its rated capacity. Double cylinder rectangular core jacks are used to lift weights and apply variable force to objects. In a given configuration, they can be applied in vertical or horizontal directions, or even both simultaneously. They have a wide usage in the construction industry where they are particularly utilized in rigging operations.
Rectangular core jacks are usually made from rigid yet lightweight metals such as steel, aluminum and bronze. Steel is the most popular due to its higher strength and stiffness, but aluminum is becoming more common for those seeking a lighter solution. These jacks come in a variety of sizes with different capacities, ranging from several tons to up to 100,000 pounds (45,000kg). They are also available in a large number of configurations, including single stage, double stage, 2- and 3-position models.
Double cylinder core jacks are primarily used to lift and support overhead loads, such as bridge and tower crane equipment, as well as a variety of heavy or awkward loads. Having two cylinders instead of just one increases their capability, enabling them to support higher loads and cover larger distances than their single-cylinder counterparts. This allows them to be used in a variety of jobs like 3-point lifts, hoist and supports, gantry jib and crawler crane work, and more.
In order for a jack to be able to safely lift and handle an object, its capacity must be matched to the weight of the object that it is lifting. Different rectangular core jacks have different capacities, and it is important to select the correct jack for the job by calculating the correct lifting capacity.
In order to help select the correct lifting capacity for a given situation, jacks are rated in “tons”, which is a unit of measure that is equal to 2,000lbs (907kg). Each jack will have a minimum, maximum, and recommended weight range listed on the product page or packaging in tons that should be matched to the weight of the object being lifted. It is typically recommended to use a jack with a lifting capacity that is at least 2-3 times greater than the actual weight being lifted. This ensures that the jack can safely and securely handle the weight of the object at any given point.
Overall, double cylinder rectangular core jacks are versatile and dependable tools used in a variety of construction and other applications. They have a variety of sizes and configurations and come with a wide range of capacities, allowing them to be used in a number of different applications. When selecting the correct size and capacity for a given project, it is important to properly calculate and determine the weight of the object being lifted and select a jack accordingly. With the correct size and capacity, double cylinder core jacks can be used for a variety of lifting and rigging jobs and provide increased safety, stability, and performance.
