The Road Vehicles (Authorisation of Special Types) (General) Order 2003

Braking requirements

7.  A mobile crane must be fitted with—

(a) an efficient brake capable of braking the mobile crane at the maximum weight permitted under paragraphs 28 to 32 for a mobile crane of the Category in question when travelling at the maximum speeds for that Category permitted by this Schedule; and

(b) an efficient parking brake capable of holding the mobile crane stationary when necessary.

8.—(1) A mobile crane is to be treated as being fitted with a brake that complies with paragraph 7 if it is fitted with a braking system that meets the construction, fitting and performance requirements for motor vehicles of category N3 set out—

(a) in Annexes I, II and VII to Council Directive 71/320/EEC; and

(b) if appropriate, in Annexes III, IV, V, VI and X to that Directive.

(2) But, in their application to a mobile crane which has a maximum axle weight exceeding 12,500 kilograms, those requirements are subject to the modifications in paragraphs 9 to 12.

9.—(1) The following modifications apply for the purposes of each Type O test conducted in accordance with Annex II to Council Directive 71/320/EEC.

(2) References to a laden vehicle are to be taken to be references to a vehicle laden with the maximum technically permissible mass specified by the manufacturer for the vehicle speed specified for the test.

(3) If the performance of a service braking device is determined by measuring the stopping distance in relation to the initial speed, the stopping distance in paragraph 2.1.1.1.1 of Annex II is to be taken to be—

(4) If the performance of the service braking device is determined by measuring the reaction time and the mean deceleration, the mean braking deceleration at normal engine speed in paragraph 2.1.1.1.1 of Annex II is to be taken to be at least 3 m/s².

(5) If the performance of a secondary braking device is determined by measuring the stopping distance in relation to the initial speed, the stopping distance in paragraph 2.1.2.1 of Annex II is to be taken to be—

(6) If the performance of the secondary braking device is determined by measuring the reaction time and the mean deceleration, the mean braking deceleration in paragraph 2.1.2.1 of Annex II is to be taken to be at least 1.45 m/s².

10.—(1) The requirements of paragraphs 2.2.1.22 and 2.2.2.13 of Annex I to Council Directive 71/320/EEC do not apply.

(2) The requirements of paragraphs 1.1.4.2 and 1.4 of Annex II to Council Directive 71/320/EEC do not apply.

(3) In Annex I to Council Directive 71/320/EEC—

(a) in paragraph 2.2.1.23 the words “not mentioned in item 2.2.1.22 above” do not apply; and

(b) in paragraph 2.2.2.14 the words “not mentioned in item 2.2.2.13 above” do not apply.

11.  For the purposes of Type I tests conducted, in accordance with paragraph 1.3 of Annex II to Council Directive 71/320/EEC, on a mobile crane falling within paragraph 9(3) of this Schedule, the reference to a laden vehicle is to be taken to be a reference to a vehicle laden with the heaviest weight possible without the sum of the weights transmitted to the road surface by all the wheels of any one axle exceeding 12,500 kilograms.

12.  The requirements of paragraph 2.1.3.2 of Annex II to Council Directive 71/320/EEC do not apply if wheel chocks are provided with the mobile crane and the wheel chocks are—

(a) suitable and sufficient;

(b) readily accessible; and

(c) capable, when used in conjunction with any parking brakes fitted to the vehicle, of holding the vehicle stationary when loaded to its maximum mass on a gradient of 12 per cent.
