SPYDERCRANE Hooks have standard deductions. The MOST IMPORTANT thing for to you understand when using the Rated Load Chart is that the Rated Load INCLUDES the weight of the hook and the wire rope. On any crane, to know how heavy of a load you can safely lift, you MUST use calculate the NET-RATED LOAD. For ALL SPYDERCRANES, we use a standard weight deduction, based on the EQUIPPED HOOK: If you are using the 1-PART HOOK. Deduct 25 lbs. If you are using the 2-PART HOOK. Deduct 35 lbs. If you are using the 4-PART HOOK. Deduct 70 lbs. 70 lbs. for the 4-Part Hook (URW205, URW295) (primary hook) 35 lbs. for the 2-Part Hook (URW094, URW095) (primary hook) 25 lbs. for the 1-Part Hook (all Micro-Crawlers) (secondary hook)
