National Foreword
This Philippine Agricultural Engineering Standards P AES 139:2004, Agricultural
Machinery - Roll-Over Protective Structures (ROPS) - Specifications was approved for
adoption as a Philippine National Standard by the Bureau of Product Standards upon the
recoI11mendation of the Agricultural Machinery Testing and Evaluation Center.

Foreword
The fonnulation of this National Standard was initiated by the Agricultural MachinelY
Testing and Evaluation Center (AMTEC) with support frOin the Depmilnent of Agriculture
(DA).
This standard has been technically prepared in accordance with BPS Directives Part 3 :2003 -
Rules for the Structure and Drafting of International Standards.
The word "shall" is used to indicate mandatory requirements to confonn to the standard.
The word "should" is used to indicate that among several possibilities one is recon1lnended as
particularly suitable without Inentioning or excluding others.
In the preparation of this standard, the following documents/publications were considered:
Alnerican Society of Agricultural Engineers (ASAE) S383.1: 1983 - Roll-over Protective
Structures (ROPS) for Wheeled Agricultural Tractors.
Guidelines for the Design, Construction, and Installation of Rollover Protective Structures
(ROPS) for all Terrain Vehicles. 1998. Occupational Health Safety and Health Service,
Departtnent of Labour, Wellington, New Zealand.
Inteillational Organization for Standardization (ISO) 3463: 1989 Wheeled Tractors for
Agriculture - Protective Stnlctures - Dynamic Test Method and Acceptance Conditions.
International Organization for Standardization (ISO) 5700: 1989 Wheeled Tractors for
Agriculture - Protective Structures - Static Test Method and Acceptance Conditions.

1 Scope
This standard specifies the requirements for roll-over protective structure (ROPS) attached to
a four-wheel tractor with a minimum of 15 kW engine power.

For the purpose of this standard, the following definitions shall apply:
3>1
structure
cab or fran1e installed on agricultural tractors to protect or minimize injury of the operator
from accidental overturning during operation (sec Figures 1 and 2)
3.2
seat
point on the central vertical plane of the seat (see Figure 3 and 4a)
NOTE For n10rc detailed specification of the SIP refer to ISO 5353.

5 Construction Requirements
5.1 Steel with an as-rolled thickness of not less than 2.5 1111n and with a carbon content
of not less than 0.2 shall be llsed in the Inanufacture of ROPS.
%
5.2 Bolts and nuts used to attach the protective structure to the nlachine fraIne and to
connect structural parts of the protective stnlcture shall exhibit suitable toughness
properties. For Inore detailed specifications of bolts and nuts, refer to P AES 311.
5.3 All welding electrodes used in the fabrication of structural n1embers and nlounts
shall be compatible with the protective structure 111aterials.
5.4 In case of a cab ROPS, safety glass shall be used.
5.5 The construction shall be rigid and durable.
5.6 ROPS equipped tractors shall be fitted with seat belt assenlblies conforming to
ISO 3776 and PAES 118.
6 Clearance
.1.1 The clearance zone is illustrated in Figures 3, 4a and 4b and dinlensions are shown
in Table 2. Referring to the figures, the zone is defined in relation to the vertical reference
plane. This reference plane shall be assmned to n10ve horizontally with the seat and
steering-vvheel during ilnpactlloading tests but to remain perpendicular to the tractor or the
protecti ve structure floor.
.2 The clearance zone assumes a seat adjustn1ent of ±75 1111n horizontally and ±30 111111
vertically frolll the seat nlid-position. Where the seat adjustnlent exceeds these values, the
clearance zones shall be nl0dified in accordance with the following:
6.1. 1 lfthe horizontal seat adjustlnent provided exceeds ±75 mnl fronl the nlid
position, then any dinlensions forward from the SIP shall be reduced, and dilnensions to the
rear fron1 the SIP increased, on the basis:
[Total adjustlnent to the rear of the seat 1nid-position 111inus 75 mm J
1.1 If the vertical seat adjustn1ent provided exceeds ±30 n1n1, then any dimensions
above the SIP shall be increased and dinlensions below the SIP reduced on the basis:
[Total adjustl11ent above the seat mid-position nlinus 30 111111J
6. L 1.3 The clearance zone is defined as in a) to j) when the tractor is standing on its wheels
on a horizontal surface, with, where applicable, the steering-wheel adjusted to the mid
position for seated driving.
a) a horizontal plane A,BJB2A2 - 840 Innl above the SIP vvith line BJB2 located 65
mm behind SIP;
1\-104
PAES 139: 2004
b) an inclined plane - G1G212I1 - perpendicular to the vertical reference plane and
including the reannost point of the seat backrest extended rearwards by 75 mm and
upwards by 30 lTIlTI, the extension of which passes through a point 840 lTIlTI above the
SIP, 215 nlm behind the SIP;
c) a cylindrical surface - AJA2bIJ - perpendicular to the vertical reference plane, with
a radius of 120 mIll tangential to the planes defined in a) and b);
d) a cylindrical surface - B1CJC2B2 - perpendicular to the vertical reference plane,
having a radius of 900 mm and center 65 lTIlTI behind and 60 lTIm below the SIP, with
the line CJC2 located 400 mm forward ofBjB2;
e) an inclined plane - CJD1D2C2 - perpendicular to the vertical reference plane, joining
the surface defined in d) at its forward edge and passing 40 mnl from the steering
wheel rim;
f) a vertical plane - DJEJE2D2 - perpendicular to the vertical reference plane 40 lnln
forward of the steering-wheel forward edge;
g) a horizontal plane --ElF lF2E2 - 60 mm below the SIP;
h) a surface, curved if necessary - GJF]F2G2 - from the bottom limit of the plane
defined in b) to the horizontal plane defined in g), following the general direction of
and parallel to a surface in contact with the seat backrest rear surface, extended
rearwards 75 mlTI and upwards 30 mm;
i) vertical planes - JJE1F1G1Hl and hE2F2G2H2 - at not less than 250 111m on either
side of the vertical reference plane where the distance EIE2 shall be equal to the
steering- wheel diatneter plus 40 lTIlTI on each side of the steering-wheel rim or 500
lTIlTI, whichever is greater;
j) parallel planes - AIBI CIDJHII, and A2B2C2D2H212 - inclined so that the plane upper
edge on the side to which the side blow is struck is at least 100 lTIlll from the
reference plane.
