Three Wire Suspension Apparatus Manufacturer,Supplier and Exporter in India

Product Code : EL-ELA-5520
Jlab Export is a leading Three Wire Suspension Apparatus Manufacturer,and suppliers in India

Three Wire Suspension Apparatus (code EL-ELA-5520) is a bench-mounted statics apparatus used to study the vertical equilibrium of two- and three-wire suspension systems and the action of the central vertical redundant force, in engineering mechanics teaching labs. A spring balance reads the tension in each of the three suspenders. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

What Is the Three Wire Suspension Apparatus Used For?

When a load hangs from two inclined wires, both tensions follow from the equilibrium of forces at the joint, so the system is statically determinate. Adding a third, central vertical wire gives three unknown tensions but still only two equilibrium equations at the joint, so one force is redundant: how the load is shared then depends on how much each wire stretches, not on statics alone. The apparatus is designed around exactly this comparison — the vertical equilibrium of a two-wire and a three-wire system, and the action of the central vertical redundant force.

Spring balances in the suspenders give the tensions directly, and threaded rods allow each suspender length to be adjusted. It is a compact piece of mechanics lab equipment for the applied mechanics, strength of materials and structural analysis practicals of engineering colleges, polytechnics and technical institutes, where it introduces the idea of redundancy before students meet statically indeterminate frames.

What to Specify When Ordering

• Quantity — the minimum order is 10 units; many departments plan one apparatus per bench group.
• Related statics apparatus — the Redundant Joint Apparatus and the Funicular Polygon and Forces Apparatus are separate products that can be quoted on the same enquiry.
• Delivery details — destination country and port or city, and delivery terms such as FOB or CIF.
• Tender reference — include it when the purchase is for a tender.

Frequently Asked Questions

What experiments does the three wire suspension apparatus cover?
Two are listed: the vertical equilibrium of a two- and three-wire suspension system, and the action of the central vertical redundant force.

Why is the central vertical wire called redundant?
Two inclined wires are enough to hold the load in equilibrium, and their tensions can be found from statics. The central wire adds a third unknown without adding an equilibrium equation, so its force depends on how the wires deform and is called the redundant force.

How are the wire tensions measured?
Each suspender has a spring balance, so the tensions are read directly. A threaded rod attached to each spring balance adjusts the length of that suspender.

At what angles are the wires set?
The two outer suspenders are at about 30 and 45 degrees to the central vertical one, and all three meet at a ring that carries the load hanger.

How does it differ from the Redundant Joint Apparatus?
Both study a three-member suspension system. This apparatus reads the tensions on spring balances in suspenders that meet at a ring; the Redundant Joint Apparatus uses spring-balance members of different stiffness and dial gauges with a magnetic base to measure the joint displacement and member elongations.

Is an instruction manual provided?
Yes. A complete instruction manual covers the apparatus, its application, the experimental procedure and typical test results.

What information is needed for an export quotation?
Send the quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling needs, and a tender reference where relevant.

Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, manufactures it in Ambala, Haryana, India, and quotes for it as the maker.

OEM Manufacturer

JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of engineering and science laboratory apparatus in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. This suspension apparatus is produced in JLab’s own works rather than bought from a trader, which means colleges, polytechnics, dealers and importers buy direct from the manufacturer, each unit is visually inspected before it ships, and repeat orders and spare parts come from the same source. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to buyers in every region — for example Botswana in Southern Africa, Guyana in South America, Senegal in West Africa, Uzbekistan in Central Asia and Bahrain in the Middle East. Details for tender buyers are on the JLab lab tenders page.

Other Statics and Structures Apparatus

• Redundant Joint Apparatus — three spring-balance members of different stiffness joined at one point, with dial gauges for displacement and elongation.
• Funicular Polygon and Forces Apparatus — for the triangle of forces, the polygon of forces and concurrent or non-concurrent coplanar forces.
• Tension Coefficients Apparatus — a wall-mounted jib and two chain ties for measuring forces in three dimensions.
• Suspension Bridge Apparatus — studies cables, which carry only direct tension, under different loads.
• Shear Legs — bench-mounted apparatus for strut and backstay forces measured with a spring balance.
