IS 10595: Stability and Suspension Key Points

Stability (Clause 4.14)

• The machine must be fully stable when rigged for operation at the manhole site.
• Stability depends on proper rigging, weight distribution, and support during operation.

Suspension and Tyres (Clause 4.14.1)

• Machine shall have pneumatic tyres of suitable size.
• Tyres mounted on axle with leaf spring type suspension to absorb shocks during towing on roads.

Accessories Related to Stability & Suspension (Clause 1.1, Table A-1)

• Pneumatic tyres and suspension ensure smooth movement.
• Accessories like slant manhole jack, rollers with jacks, and pipe clamps assist in stable positioning.
• Winch buckets and wire ropes aid in operational stability.

Additional Notes:

• Leaf spring suspension formula for load distribution:
  [ F = \frac{W}{n} ] where ( F ) = load per spring, ( W ) = total weight on axle, ( n ) = number of springs.

• Tyre size and pressure must match machine weight and towing speed for stability.
