Using the Rated Load Chart Lifting With Your SPYDERCRANE KBT 5.6 Welcome to Lesson Topic 5.6, Using the Rated Load Chart.

Topic Overview and Contents This Lesson Topic (Using the Rated Load Chart) is designed to provide you with an understanding of how to use the RATED LOAD CHART of the 094-, 095- and 200-Series SPYDERCRANE You will learn about: The difference between RATED LOAD and NET-RATED LOAD How to combine what you have learned about DEPLOYMENT STATES, BOOM STAGES, and WORKING RADII to effectively use the RATED LOAD CHART It is YOUR RESPONSIBILITY to read and understand the user manuals included with your SPYDERCRANE and the warning decals posted on it This Lesson Topic covers all SPYDERCRANE Micro-Crawlers This lesson topic covers all SPYDERCRANE Micro-Crawlers: the 094-, 095-, and 200-Series

Learning Objective(s) The desired learning objective for this Lesson Topic is for each student to… DLO 5.6.1 List the THREE things you MUST know to use the RATED LOAD CHART. DLO 5.6.2 Explain how the RATED LOAD CHART is divided into RATED LOAD TABLES. DLO 5.6.3 Define the different DEPLOYMENT STATE ROWS of the RATED LOAD TABLE. DLO 5.6.4 List the steps in using the RATED LOAD CHART to figure out the SPYDERCRANE's RATED LOAD CAPACITY. DLO 5.6.5 Define RATED LOAD and NET-RATED LOAD. DLO 5.6.6 Explain the SPYDERCRANE-STANDARD HOOK DEDUCTIONS for the 1-, 2-, and 4-PART HOOKS. There are a large number of learning objectives associated with this lesson segment, make sure that you can accomplish them all before moving on.

Where to Find and When to Use the Rated Load Chart The Rated Load Chart is an Operator Aid located near your SPYDERCRANE’s Crane Control Group (CCG) Use the Chart to figure out your SPYDERCRANE’s Rated Load Capacity     For all SPYDERCRANEs, the RATED LOAD CHART is located near the CRANE CONTROL GROUP, within the operator's line-of-sight.  For SPYDERCRANE Micro-Crawlers (094-Series, 095-Series, 200-Series), the Rated Load Chart is on the curbside front of the SPYDERCRANE's carrier.  If you have a newer (2018) SPYDERCRANE, there may be two Rated Load Charts, one for the PRIMARY HOOK (either the 2-PART HOOK or 4-PART HOOK) and another for the SECONDARY HOOK (the 1-PART HOOK). 

The Three Variables To use the Rated Load Chart, you must know three things:     Once again, you MUST know three things before you can use the Rated Load Chart: Your SPYDERCRANE’s Deployment State It’s Boom Stage And it’s Working Radius

* Rated Load Chart for the URW295CP1URS/P The Rated Load Chart * Rated Load Chart for the URW295CP1URS/P The information in the Rated Load Chart applies ONLY to the SPYDERCRANE it is posted on The Rated Load Chart is used with the SPYDERCRANE’s main boom (not the jib) and the Primary Hook The Rated Load Chart has an information section and rated load tables section     The information contained on the Rated Load Chart is only applicable to the SPYDERCRANE it is posted on.  The Rated Load Chart is divided into two major elements: the LOAD TABLES ELEMENT and the USE AND WARNINGS ELEMENT. The Use and Warnings Elements contains the direction for using the Rated Load Chart and some warnings against improper deployment and lifting.  The Load Tables Element is the part of the chart that you will use to figure out your SPYDERCRANE's Rated Load Capacity.

The Load Tables Element​ The Rated Load Tables are organized by Boom Stage Boom Stages 1 and 2 are combined into a single table Except for the 94-Series Rated Load Charts     The Rated Load Chart is broken down into individual LOAD TABLES.  These tables apply to a specific Boom Stage (for most SPYDERCRANE models, Boom Stage 1 and 2 share a table).  The remaining Boom Stages have their own tables

Breaking Down the Rated Load Table Each table has three rows: Working Radius Row     Each Load Table contains three rows of information: The WORKING RADIUS ROW The top row of the table lists the available working radius values for that specific Load Table. 

Breaking Down the Rated Load Table Each table has three rows: Working Radius Row MAX-EXT Rated Load Row The MAX-EXT RATED LOADS ROW The middle row of the table lists the different Rated Load Capacities, if you deployed your SPYDERCRANE using the Maximum-Extended Deployment State (MAX-EXT).

Breaking Down the Rated Load Table Each table has three rows: Working Radius Row MAX-EXT Rated Load Row NOT-MAX-EXT Rated Load Row THE NOT-MAX-EXT RATED LOADS ROW You would use the bottom row if you deployed your SPYDERCRANE using the Not-Maximum-Extended Deployment State (NOT-MAX-EXT). 

Breaking Down the Rated Load Table Each table has three rows: Working Radius Row MAX-EXT Rated Load Row NOT-MAX-EXT Rated Load Row Each Rated Load Table has three rows. The top row is the Working Radius Row and it corresponds to the Working Radius you get from the Boom Angle Indicator. The second row is the Rated Load Row for a SPYDERCRANE using the MAX-EXT Deployment State The bottom row is the Rated Load Row for a SPYDERCRANE using the NOT-MAX Deployment State

Using the Rated Load Chart     Once you have figured out your SPYDERCRANE's Working Radius; Boom Stage; and Deployment State, you can use the Rated Load Chart to figure out your SPYDERCRANE's Rated Load Capacity:  Select the Load Table. Select the Working Radius.  Select the Deployment State. Find the Rated Load. 

Rated Loads Versus Net-Rated Loads RATED LOAD refers to the safe lifting capacity of the SPYDERCRANE, INCLUDING the weight of the HOOK and WIRE ROPE Rated Load Net-Rated Load Rated Load is often referred to as Gross Load or Gross Weight You MUST figure out the NET-RATED LOAD By DEDUCTING the weight of the SPYDERCRANE’s hook and wire rope 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)
