Jolting Apparatus
Product Code : EL-CTLE-10332
Jolting Apparatus (code EL-CTLE-10332) is a motor-driven table that compacts specimens in a mould clamped to it by repeatedly lifting the table and letting it fall freely onto a stop. A cam turning at 60 Rev/Min raises the table, a stroke counter with micro-switch halts the machine after 60 jolts, and the unit runs on a 230 V single phase A.C. supply and is supplied complete with mould and hopper.

What Is the Jolting Apparatus Used For?
Cement strength is commonly found by testing prisms of a standard mortar, and each prism has to be compacted in the same way for results to be comparable. The three-compartment steel mould, with the hopper on top, is clamped to the table and filled with mortar; the cam then lifts the table and drops it onto the stop, and the stroke counter ends the run after 60 jolts, so every batch receives the same compaction. The prisms are later removed with the de-moulding apparatus, cured and tested. The standards listed are IS 1727 1967, IS 4031 1968, ASTM C 394 and C 64.
What to Specify When Ordering
- Quantity — the number of jolting apparatus required.
- Counter — whether the digital preset counter, supplied at extra cost, is wanted.
- Spares — any extra three-compartment steel moulds with base plate (40 × 40 × 160 mm) and the apparatus for de-moulding the specimen.
Frequently Asked Questions
How does the jolting action work?
A motor and gearbox drive a cam through a V-belt and pulleys. The cam raises the table, which then falls freely so that its lug strikes a stop with a rounded upper surface.
How many jolts does it give, and how is the run stopped?
The cam rotates at 60 Rev/Min, and a stroke counter fitted with a micro-switch stops the machine automatically once 60 jolts have been applied.
What mould is used with it?
The spares list includes a steel mould with base plate having three compartments, each 40 × 40 × 160 mm internally; locating pins hold the compartments, and the mould and hopper clamp to the table.
What power supply does it need?
It is suitable for operation on a 230 Volts, single phase, A.C. supply, with the motor driving the cam through a gearbox, V-belt and pulleys.
Is a digital counter available?
Yes. A Digital Preset Counter can be supplied at an extra cost, in addition to the standard stroke counter with micro-switch.
Which standards are listed for the apparatus?
The standards listed are IS 1727 1967, IS 4031 1968, ASTM C 394 and C 64, and an apparatus for de-moulding the specimens is offered among the accessories.
