由于电动环链葫芦最大承载500kg，设计满足要求。电动葫芦天花板挂点安

Since the electric chain hoist maximum load 500kg, designed to meet the requirements. <br>Electric hoist ceiling hanging point safety factor of 3.0, the design values anchor point chain need not be less than 1500kg. <br>Meanwhile rigging electric chain using the safety factor is taken 9.0, the chain breaking load of not less than 4500kg required will suffice.

Because the electric ring chain hoist carries a maximum of 500kg, the design meets the requirements.<br>The safety factor of the ceiling hanging point of the electric hoist is taken 3.0, the upper anchor ingress design value of the ring chain should be no less than 1500kg.<br>At the same time, the electric ring chain used to take the rope safety factor of 9.0, then the chain's broken pull force needs not less than 4500kg to meet the requirements.

As the maximum load of the electric chain hoist is 500kg, the design meets the requirements.<br>If the safety factor of the ceiling hanging point of the electric hoist is 3.0, the design value of the upper anchor point of the chain link shall not be less than 1500kg.<br>At the same time, if the safety factor of rigging used in the electric chain is 9.0, the breaking force of the chain shall not be less than 4500kg, that is to say, the requirements shall be met.
