Manuals Operator, service and parts manuals depict correct crane operation, maintenance procedures and parts listing. Warranty -month warranty covers parts and labor resulting from defects in material and workmanship.. Lifting off the main boom point while the swingaround jib is erected is not intended or approved. 11. All load ratings above the heavy line are based on machine structural competence and do not exceed 5% of tipping. Load ratings below are stability limited and do not exceed 5% of tipping.. Do not operate a Manitowoc truck-mounted crane or accessories within ' (3,05 m) of live power lines. 13. This capacity chart is for reference only and must not be used for specific serial number cranes. 3 Warning 1. The operator must read and understand the owner s manual before operating this crane. 2. Positioning or operation of crane beyond areas shown on this chart is not intended or approved except where specified in owner s manual. 3. Loaded boom angles at specified boom lengths give only an approximation of the operating radius. The boom angle before loading should be greater to account for deflections. Do not exceed the operating radius for rated loads. 4. The operating radius shown in the jib rating chart is for fully extended boom only. When boom is not fully extended, use only loaded boom angle to determine load rating of jib. 5. For boom angles shown on jib load rating chart, use rating of next lower boom angle.. For boom lengths not shown, use rating of next shorter or longer boom length, whichever is less. For radii not shown, use rating of next longer radius. 7. Crane load ratings on outriggers are based on freely suspended loads with the machine leveled and standing on a firm, uniform supporting surface. No attempt shall be made to move a load horizontally on the ground in any direction.. Practical working loads depend on supporting surface, wind, and other factors affecting stability such as hazardous surroundings, experience of personnel, and proper handling, all of which must be taken into account by the operator. 9. The maximum load which may be telescoped is limited by hydraulic pressure, boom angle, and boom lubrication. It is safe to attempt to telescope any load within the limits of the load rating chart. Information 1. Deductions must be made from rated loads for stowed jib, optional attachments, hooks, and loadblocks (see deduction chart). Weights of slings and all other loadhandling devices shall be considered a part of the load. 2. Load ratings above the heavy line are structurally limited capacities. Load ratings below the heavy line are stability limited capacities and do not exceed 5% of tipping. Definitions 1. Operating radius (r ) is the horizontal distance from the axis of rotation to the center of the vertical hoist line or tackle with load applied (see below). 2. Loaded boom angle ( ), as shown in the column headed by, is the included angle between the horizontal and longitudinal axis of the boom base after lifting rated load at rated radius (see below). r models 300C, 304C NOTE: Due to continuing improvements, Manitowoc Boom Trucks reserves the right to change product specifications without notice.
