Dynamic Trolleys Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-5742
Jlab Export is a leading Dynamic Trolleys Manufacturer,and suppliers in India
Dynamic Trolleys (code EL-SLE-5742) are hardwood dynamics trolleys, listed at 300 mm with reinforced ends, used for force, motion and momentum experiments in school and college mechanics practicals. They run on ball bearing wheels, have a quick release mechanism and can be stacked on one another. They are made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Dynamics Trolleys?
| Model | Body | Wheels | Other listed details |
|---|---|---|---|
| These trolleys (EL-SLE-5742) | Hardwood, reinforced ends | Ball bearing | 300 mm; quick release mechanism; stackable |
| Dynamic Trolley | Wood | Three wheels | Spring-loaded rod that pushes the trolley when released |
| Wooden Dynamic Trolley | Wood, sold as an identical pair | Three wheels | 300 mm long; spring-loaded rod; stacking with removable pins; supplied with elastic rings, springs, pins, corks, needles and a releasing pin |
| Dynamic Carts Trolleys | High-impact plastic | Ball bearing, three wheels | Firing pin with two settings and a locking feature |
Choose these trolleys when you want hardwood bodies with ball bearing wheels that stack for changing the moving mass. The wooden pair comes with a full set of collision accessories, and the plastic carts suit buyers who prefer a moulded body with a two-setting firing pin.
What Are Dynamic Trolleys Used For?
A dynamics trolley is the moving body in classic mechanics experiments. Pulled along a bench or runway by a string running over a table pulley to a hanging mass, it shows how acceleration depends on the force applied and on the mass moved, which is Newton’s second law as taught in the force and laws of motion chapter of class 9 science and in class 11 physics. Stacking one trolley on another doubles the moving mass without changing the force, and running two trolleys into each other lets students compare momentum before and after a collision.
For reliable results, tilt the runway slightly until a gently pushed trolley rolls at a steady speed, so friction is compensated, and record the motion with a ticker tape timer: the spacing of the dots gives velocity and acceleration. Keep the wheels free of dust and stop the trolley at the end of the runway rather than letting it fall to the floor.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; order enough for stacking and for two trolleys per collision set.
- Quick release mechanism — the listing names it without describing it, so state how you intend to use it and ask JLab to confirm.
- Runway, timer, pulley and masses — add them to the same enquiry so each bench has a complete dynamics set.
Frequently Asked Questions
What are these trolleys made of?
Hardwood, with reinforced ends, running on ball bearing wheels. The listed size is 300 mm.
Can the trolleys be stacked?
Yes, the listing describes them as stackable, which lets you double or triple the moving mass in Newton’s second law and collision experiments.
What does the quick release mechanism do?
The listing names a quick release mechanism but does not describe it. Ask JLab to confirm how it works if your experiments depend on it, for example for explosion-type momentum demonstrations.
How do they differ from the Wooden Dynamic Trolley pair?
Both are wooden. The Wooden Dynamic Trolley is sold as an identical pair, mounted on three wheels with a spring-loaded rod and supplied with stacking pins and collision accessories; these hardwood trolleys are listed with reinforced ends, ball bearing wheels and a quick release mechanism.
Is a runway or ticker timer included?
No, the listing covers the trolley. The trolley runway, ticker tape timer, table pulley and slotted masses are separate items, linked below.
Who manufactures these trolleys?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes them at its works in Ambala, Haryana, India, and quotes for them as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics and school lab equipment in India, incorporated in 2017 with its base on Hargolal Road, Ambala, Haryana. The trolleys are made in JLab’s own works rather than sourced through a trader, so schools, colleges, dealers and importers buy them factory-direct, every trolley is visually checked before dispatch, and follow-up orders for more trolleys are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Bolivia in South America, Serbia in Southern Europe, Uzbekistan in Central Asia, Tonga in Oceania and Nepal in South Asia. Tender buyers can refer to the JLab lab tenders page.
Complete the Dynamics Set
- Trolley Runway — a warp-resistant hardwood runway with reinforced sides for the trolley to run on.
- Ticker Tape Timer — marks dots on a paper tape pulled by the trolley; runs on a 6–12 V AC supply.
- Pulleys Aluminium — includes a single pulley on a table clamp for the string and hanging mass.
- Masses — a hanger with nine slotted 10 g masses to provide the accelerating force.
