The 3 Ton Mast Type Jib Crane is engineered for powerful material handling with a compact footprint and high structural efficiency. It installs directly into the floor and braces against an existing overhead support—offering full 360-degree manual rotation and excellent hook coverage without the need for a full freestanding base.
With spans and boom heights from 8 to 20 feet, this crane offers the strength and adaptability needed for welding bays, production lines, or equipment maintenance stations. The mast-style support ensures minimal deflection under heavy loads and maximizes vertical clearance for high-cycle use.

The Fine Print:
USA Jib Cranes warrants manual push/pull Jib and Gantry Crane products it manufactures against defects in material or workmanship for a period of eleven years from date of receipt by purchaser or customer. This warranty does not cover failure or defect in paint or material finish. This warranty does not cover failure or defect caused by operation in excess of recommended rated capacities, misuses, negligence or accident, and alteration or repair of any kind not authorized by USA Jib Cranes. USA Jib Cranes systems shall not be modified after manufacture without written authorization of USA Jib Cranes. Any field modifications made without written authorization of USA Jib Cranes shall void all USA Jib Cranes’ warranty obligation.
USA Jib Cranes agrees to furnish the same or substantially similar replacement part (new or repaired) free of charge, providing the buyer gives immediate written notice of alleged defects, and if requested by USA Jib Cranes, returns the defective parts to the factory, for USA Jib Cranes’ inspection and examination. Purchaser or end user shall be solely responsible for all freight and transportation costs incurred in connection with any warranty work provided by USA Jib Cranes hereunder. USA Jib Cranes will not be liable for any loss, injury or damage to persons or property, nor for damages of any kind resulting from failure or defective operation of any materials or equipment furnished hereunder.
USA Jib Cranes shall not be liable under any circumstances for any incidental, special and/or consequential damages whatsoever, whether or not foreseeable, including but not limited to damages for lost profits and all such incidental, special and/or consequential damages are hereby also specifically disclaimed. This warranty applies only to USA Jib Cranes equipment or materials which, after our inspection, are determined to be defective either in material supplied or workmanship performed by USA Jib Cranes.
Where equipment is furnished by USA Jib Cranes but not of its manufacture, USA Jib Cranes’ liability is limited to such adjustment as the actual manufacturer makes to USA Jib Cranes. USA Jib Cranes will not be liable for the cost of repairs, alterations, or replacements or any expense connected therewith made or incurred by the purchaser or his agents or employees, except upon written authority from USA Jib Cranes. This warranty is personal to purchaser only and applies only to equipment which purchaser has properly operated and maintained in accordance with USA Jib Cranes’ written instructions. USA Jib Cranes assumes no liability for any consequential damages suffered through the use of or loss of use of its equipment.
This constitutes USA Jib Cranes’ sole warranty with respect to the equipment and material manufactured by itself. USA Jib Cranes makes no other warranty of any kind whatsoever, expressed or implied, and all implied warranties of merchantability and fitness for a particular purpose which exceed the aforementioned obligation are hereby disclaimed by USA Jib Cranes.
Design Standards
All USA JIB CRANES Jib Cranes are structurally designed in accordance with the AISC Steel Construction Manual.
All USA JIB CRANES Cranes have a design factor of 15% of the allowable capacity for hoist weight and 25% of the allowable capacity for impact.
All designs meet AISC standards as they pertain to jibs and overhead cranes. All of our cranes are in accordance with OSHA specification 1910.179. All design and manufacturing is done in accordance to ANSI specification B30.11 as they apply to jib cranes and overhead cranes. All jib and gantry cranes are built to CMAA specification No. 74. All workstation bridge cranes are built to MMA MH27.2.
Fabrication Standards
All welding of USA JIB CRANES cranes adheres to the American Welding Society’s (AWS) standards: D1.1 for steel and D1.2 for aluminum. All welders are AWS certified.
Material Standards
All steel beams and shapes used by USA JIB CRANES are a minimum of ASTM A-36 designation. All steel pipes are ASTM A-53 Grade B. All steel tubing are ASTM A-500 Grade B. All aluminum used meets ASTM B308 for 6061-T6 aluminum.
Painting Procedure
All finished cranes are wire wheel cleaned and wiped down with a solvent solution paint prep to remove any standing rust, oil, or dirt that may impede in paint adhesion. Indoor and outdoor paint finishes are applied with an air-assisted wet paint sprayer. Standard indoor paint consists of a one to two coat, 2 mil +/- application with a DTM water reducible yellow enamel. Standard outdoor paint finish consists of a one coat DTM primer with two coats of water reducible safety yellow acrylic enamel.
Deflection
USA JIB CRANES manufactures cranes to a specific deflection value, however, the value of this formula is theoretical and will be increased during field load tests due to variables such as: installation, foundation rigidity, or the standard variation in thickness tolerances for the piping, tubing, steel plate and sheet metal. Some variation above (or below) deflections defined by the manufacturer is considered normal.
When measuring deflection for safety standards, the deflection is measured at 100 percent capacity (L (span in inches)/100 for freestanding (350), L (span in inches)/150 for wall cantilever (313), free standing (351), and mast type (314), and L/450 for wall bracket (311) cranes), rather than the 125 percent load test. According to ANSI Standards (ANSI/ASME B30.2), “Standard deflection must be measured with a load of 100 percent of the rated capacity.” During load testing at 125%, deflection values will thus be greater than published deflection. Using this formula, ‘L’ (meaning Length or span) measured in inches / 100, 150, or 450 will result in a theoretically calculated deflection. Load tests at 125% of rated capacity plus variables listed above can result in up to twice the theoretical deflection value.
