3.16.1 The structure of the ladder shall not have any parts or protrusions that would
cause injuries. The handrails and pedals of the ladder shall have a reliable strength;
the surface of the pedals shall be non-slippery. The various parts shall be reliably fixed.
3.16.2 The height from the upper plane of the first step of the ladder to the ground shall
be not greater than 550 mm; the interval among the pedals shall be not greater than
300 mm. Under special circumstances (rice harvester, crawler walking wheel or tilt
compensation mechanism), the height of the lowest step of the ladder from the ground
may be greater than 550 mm, but shall not exceed 700 mm.
3.16.3 The gradient of the ladder shall be such that when you descend from the ladder,
you can see the outer edge of the next step of the ladder when you look down.
3.16.4 When the ladder moves upwards or downwards, it shall not cause squeezing,
or impact the operator or the attendees.
3.16.5 The depth of ladder pedal (the interval between the front edge of the step and
the adjacent parts): if there is a closed damper behind the ladder, then, the depth shall
be not less than 150 mm; if there is no closed damper, then, the depth shall be not less
than 200 mm. The depth of the steps of other get-on passages shall be not less than
150 mm.
3.16.6 The interval between the pedal of the ladder to the tyre shall be not less than
25 mm. The radial free clearance between the driving wheel and the upper part shall
be not less than 60 mm.
3.16.7 Handrails shall be provided on both sides of the ladder, so as to maintain the
operator in contact with the ladder at 3 points. The cross-sectional diameter of the
handrails shall be between 25 mm ~ 35 mm; the height of the lowest end of the
handrails from the ground shall be not greater than 1,600 mm. The rear side of the
handrails shall have a minimum clearance of 50 mm. A gripper shall be set at a height
of 1,000 mm from the highest step of the ladder; the length of the gripper shall be at
least 150 mm.
3.17 The ladders and passages to access the maintenance platform shall comply with
the requirements specified in 3.16. Under special circumstances (limited by height),
the height of the handrail may be less than 1,000 mm, but shall not be less than 650
mm.
On the maintenance platform, a guardrail with a height of 1,000 mm shall be set, so as
to prevent the staff from falling from the machine. Under special circumstances (limited
by height), the height of the guardrail / handrail may be less than 1,000 mm, but shall
not be less than 650 mm.
3.18 The parts where dangers would easily occur, shall be equipped with protective
devices in accordance with the stipulations of GB 10395.1. In addition, safety signs
shall be set...
