Quarry Brake Test

What the Law requires!

Under Health and Safety Legislation, a vehicle is a place of work. The law requires that workplace are maintained in a condition that is safe and without risk to safety and health.

Employers have duties under the Safety, Health and Welfare at Work Act 2005 to ensure, so far as is reasonably practicable, the health and safety of their employees and others who may be affected by their work activities (other road users).

This includes providing systems of work that are planned, organised, performed, maintained and revised.

Reason for Brake Test

The Quarry brake test is mainly carried out on rubber-tyre vehicles examples include loading shovels, dumper and graders.

We carry out brake testing in quarries to accurately check and make sure the plant you have is safe to operate by your employees. This test can therefore give you peace of mind to know your plant can be operated safely. By doing the Quarry break test you are complying with Health and Safety Regulations.

The interval between brake testing is dependent upon a number of factors such as vehicle type, vehicle history, road conditions and usage but should not exceed 6 monthly intervals. A suitable inspection scheme should be in place to ensure brakes are in good condition at all times

Our Test Equipment

Our test equipment will give a full record data of result which can be viewed instantly after test via print/email.

The brake test is performed to determine your vehicles performance. It can be used to monitor the condition of the brake components in conjunction with normal, routine inspection.

The brake test will test the performance of both the service brake (foot brake)and the hand brake(parking brake)and will report the magnitude of any sideways pull detected during testing.

When Gracon carry out a brake test we adhere to all safety requirements, in doing so we inform the customer with additional information about the brake test. The minimum brake performance for rubber tyred machines is a brake efficiency of 28% for a loading shovel without payload. A figure of 19% is required for rigid framed and articulated steer dump trucks with a mass over 32 tonne and tested with payload. These figures are referred to in BS EN ISO 3450 1996.

We measure:

Peak Deceleration: this test corresponds to the peak brake efficiency, this is the maximum recorded G force expressed as percentage one G #

Average Deceleration: this refers to the average G force (m/s2) over the duration of the test, in the front to rear direction.

Peak Acceleration: this is the maximum-recorded G force (m/s2) detected during the test in left or right direction.

Vehicle Pull to the Left (or Right): This is an indication of the direction from the centre the vehicle is deviating towards during the test.

Stopping Distance (meters): This is an estimate of the distance the vehicle travels from commencement of braking to complete stop. It is calculated from Average Deceleration and the test time.

Test Speed: This is an estimate of the speed at which the vehicle was travelling when braking was commenced. It is calculated from the average deceleration and stopping distance.

Brake Efficiency: This is the average brake efficiency figure.
