Testing earth-moving machinery – Machine-mounted retrieval device. Performance requirements
Published By | Publication Date | Number of Pages |
BSI | 2006 | 10 |
This International Standard defines the performance requirements of a retrieval device mounted on an earth-moving machine listed in ISO 6165. Requirements for verification testing, if needed, are included.
Studies have shown that the tow rope, used for retrieving a large disabled or mired earth-moving machine is seldom larger than 40 mm diameter wire rope. This is typically the largest size that can be handled by the person connecting the tow rope to the machine.
Therefore, this International Standard is applicable to machine-mounted retrieval devices of capacities not exceeding 106 N. This value corresponds to the minimum breaking force of a 40 mm diameter Group 3 wire rope with steel core as listed in ISO 2408.
NOTE 1 In accordance with ISO 6750, information on the location and instructions for proper use of retrieval devices is provided in the operator manual.
Applicable to devices with a capacity not exceeding 106 N, mounted on an earth-moving machine listed in BS 6914-1.

5 | 1 Scope This International Standard defines the performance requirements of a retrieval device mounted on an earth-moving machine listed in ISO 6165. Requirements for verification testing, if needed, are included. Studies have shown that the tow rope, used for retrieving a large disabled or mired earth-moving machine is seldom larger than 4… Therefore, this International Standard is applicable to machine-mounted retrieval devices of capacities not exceeding 106 N. This value corresponds to the minimum breaking force of a 40 mm diameter Group 3 wire rope with steel core as listed in ISO 2408. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International St… ISO 6016:1982, Earth-moving machinery – Methods of measuring the masses of whole machines, their equipment and components.

6 | 4.6 The machine-mounted retrieval device may be mounted at the front and/or rear of the machine. It shall be in a location that is easily accessible for attaching a tow rope, a chain, or a tow bar. For machines with a machine operating mass larger than 105 kg, a second retrieval device should be provided on the same end of the machine. Each device shall conform with the requirements of this International Standard. 4.7 The machine operating manual shall provide instructions regarding the method of retrieving or towing the machine if the manu… 5 Verification 5.1 The performance requirements of the retrieval device and its supporting structure on the machine shall be verified by testing or by calculation. 5.2 If verified by testing, one pull at the maximum pull angle in the horizontal plane and one pull at the maximum pull angle in… |
