Sizing Industrial Shock Absorbers for
Controlled Descent of Mass
In many industrial processes, heavy masses must descend in a controlled and safe manner rather than free fall, requiring carefully selected damping systems. At Shockbuffer, we offer expert industrial shock absorber selection and precise sizing of shock absorbers for applications where a controlled descent is needed to protect machinery and ensure operator safety. Our large industrial shock absorbers are engineered to handle the high kinetic energy associated with slow, guided downward movement of heavy loads, delivering smooth deceleration and reducing structural stress. Choosing the right shock absorber for machinery extends equipment life and maintains reliable operation even under heavy-duty cycles.
Formulae
E1 = W · v · 0.5
E2 = W · g · s
E3 = E1 + E2
E4 = E3 · c
vD = v
We = (2 · E3) / vD

Example: Sizing Industrial Shock Absorbers for Controlled Descent of Mass
W = 1000 kg
v = 0.5 m/s
s = 0.500 m
c = 50 /hr
E1 = 1000 · 0.5 · 0.5 = 125 Nm
E2 = 1000 · 9.81 · 0.500 = 4905 Nm
E3 = 125 + 4905 = 5030 Nm
E4 = 5030 · 50 = 251500 Nm/hr
We = (2 · 5030 ) / 0.5 = 40240 kg

Applications of Industrial Shock Absorbers
Typical shock absorber applications in this category include:
Vertical lifting tables or scissor lifts lowering heavy parts or pallets
-
Hoists and cranes that lower large loads onto workstations or storage areas
-
Controlled lowering of molds or dies in large presses
-
Descent of heavy doors, ramps, or access platforms
-
Guided lowering of counterweighted systems in assembly lines
-
Test equipment that simulates slow, controlled drop of large masses
In all these cases, a large industrial shock absorber must be sized to handle the kinetic energy generated by the descending mass, ensuring smooth stopping and preventing excessive vibration or impact.
