NOTES FOR LIFTING CAPACITIES, 1 Rated loads as shown on lift chart pertain to this machine as originally manufactured and equipped Modifications. to the machine or use of optional equipment other than that specified can result in a reduction of capacity. 2 Construction equipment can be hazardous if improperly operated or maintained Operation and maintenance of this. machine shall be in compliance with the information in the Operator s and Safety Handbook Service Manual and. Parts Manual supplied with this machine If these manuals are missing order replacements from the manufacturer. through the distributor, 3 The operator and other personnel associated with machine shall fully acquaint themselves with the latest American.
National Safety Standards ASME ANSI for cranes, 1 The machine shall be level and on a firm supporting surface Depending on the nature of the supporting surface. it may be necessary to have structural supports under the outrigger floats or tires to spread the load to a larger bearing. 2 For outrigger operation all outriggers shall be properly extended with tires raised free of crane weight before. operating the boom or lifting loads, 3 When machine is equipped with center front stabilizer the front stabilizer shall be set in accordance with instructions. in Operator s and Safety Handbook, 4 When equipped with removable and or extendible counterweight the proper counterweight shall be installed and fully. extended before and during operation, 5 With certain boom and hoist tackle combinations maximum capacities may not be obtainable with standard cable. 6 Unless approved by the crane manufacturer do not travel with boom extension or jib erected unless otherwise noted. Refer to Operator s and Safety Handbook for job site travel information. 7 Inspect vehicle and crane including crane operation prior to use each day. 8 Always level the crane with the level indicator located at each outrigger control station. 1 Rated loads at rated radius shall not be exceeded Do not attempt to tip the machine to determine allowable loads. For clamshell grapple magnet or concrete bucket operation weight of component and load must not exceed 80. of rated lifting capacities, 2 All rated loads have been tested to and meet the requirements of SAE J1063 Cantilevered Boom Crane Structures.
Method of Test and do not exceed 85 of the tipping load on outriggers fully extended and SAE J1289 Mobile. Crane Stability Ratings 1 25P T 0 1A on outriggers 50 and 0 extended fully retracted as determined by. SAE J765 Crane Stability Test Code, 3 Rated loads include the weight of hookblock slings and auxiliary lifting devices and their weights shall be subtracted. from the listed rating to obtain the net load to be lifted When more than the minimum required parts of line needed. to pick the load are used the additional rope weight as measured from the lower sheaves of the main boom nose. shall be considered part of the load to be lifted When both the hook block and headache ball are reeved the lifting. device that is NOT in use including the line as measured from the lower sheave s of the nose supporting the unused. device shall be considered part of the load, 4 Load ratings are based on freely suspended loads No attempt shall be made to move a load horizontally on the ground. in any direction, 5 The maximum in service wind speed is 20 m p h on the boom capacities and 15 m p h on the jib capacities It is. recommended when wind velocity is above 20 m p h rated loads and boom lengths shall be appropriately reduced. For machines not in service the main boom should be retracted and lowered with the swing brake set in wind velocities. over 30 m p h, 6 Rated loads are for lift crane service only. 7 Do not operate at a radius or boom length where capacities are not listed At these positions the machine may overturn. without any load on the hook, 8 The maximum load which can be telescoped is not definable because of variations in loadings and crane maintenance.
but it is safe to attempt retraction and extension of the boom within the limits of the capacity chart. 9 When the boom length or lift radius or both are between values listed the smallest load shown at either the next larger. radius or next longer or shorter boom length shall be used. 10 For safe operation the user shall make due allowances for his particular job conditions such as soft or uneven. ground out of level conditions high winds side loads pendulum action jerking or sudden stopping of loads. experience of personnel two machine tandem lifts traveling with loads electric wires obstacles hazardous. conditions etc Side pull on boom or jib is extremely dangerous. NBT45 S N 295995 4, NOTES FOR LIFTING CAPACITIES cont d. OPERATION cont d, 11 Never handle personnel with this machine unless the requirements of the applicable national state and local. regulations and safety codes are met, 12 The boom angle before loading should be greater than the loaded boom angle to account for deflection. 13 Capacities appearing above the bold line are based on structural strength and tipping should not be relied upon as. a capacity limitation, 14 When operating the machine in the On Outriggers 50 Extended 17 5 spread mode the outrigger beam pins. must be engaged When operating in the On Outriggers 0 Extended 6 5 spread mode the outrigger beams. must be fully retracted Failure to follow these precautions could result in structural damage or loss of stability of the. 15 Do not lift loads when boom is fully lowered The Load Moment Indicator LMI senses pressure and will not provide. warnings or lockout The crane can become overloaded if lift cylinder s is fully retracted. 16 Use LMI angle indicator as reference only, 17 Do not exceed extension capacities at any reduced boom length.
18 Boom must be fully retracted against boom stops at all times when lifting minimum boom length capacity loads. 19 Always pay out load line before extending boom to avoid damaging loadline or crane structure or tripping anti two. block system, 20 The maximum outrigger pad load is 63 100 lb for a GVW of 19 760 lb minimum chassis requirement. 21 Loads lifted must be within safe winch capacity Multiple part rope reeving must be used on loads exceeding winch. single part rated pull Auxiliary boom head rated for single part use except multi reeve group used for nominal rated. load Extensions are rated for single part use only. 22 Do not operate the boom over personnel or allow them to walk or stand beneath the boom or load. 23 Do not allow personnel on carrier deck or crane frame area when rotating crane. 24 Rated loads must be reduced when lifting at the boom tip with jib stowed or erected Refer to the chart labeled Rated. Load Reductions with Extension for the reduction at each boom length. 25 Do not allow personnel to ride on hook hook block load or any device attached to the loadline Handling of personnel. is only permitted with full extension of all outrigger beams Use only National Crane approved baskets. 26 If using an offsettable extension do not use personnel basket with extension deployed at 30 degree offset. 27 Operate controls slowly and smoothly to avoid damage to crane or personnel. 28 Boom must be in carrying rack and outriggers fully retracted for travel. 29 Maintain a clearance of at least 10 feet between any part of the crane loadline or load and any electrical line carrying. up to 50 000 volts One foot of clearance is required for every additional 30 000 volts or less. DEFINITIONS, 1 Operating Radius Horizontal distance from a projection of the axis of rotation to the supporting surface before loading. to the center of the vertical hoist line or tackle with load applied. 2 Loaded Boom Angle Shown in Parenthesis on Main Boom Capacity Chart is the angle between the boom base. section and the horizontal after lifting the rated load at the rated radius with the rated boom length. 3 Working Area Areas measured in a circular arc about the center line of rotation as shown on the working area. 4 Freely Suspended Load Load hanging free with no direct external force applied except by the lift cable. 5 Side Load Horizontal force applied to the lifted load either on the ground or in the air. 6 No load stability limit The stability limit radius is the radius beyond which it is not permitted to position the boom plus. block configuration because machine can overturn without any load on the hook. 7 Structural length limit An area where the boom or the boom with extension deployed cannot be extended because. of structural limitations, NBT45 S N 295995 5, LINE PULLS AND REEVING INFORMATION.
