Dual Brake System
Disc type motor brake working with a Weston style mechanical load brake provides load lowering control. Electric brake is designed for easy access and simple adjustment.
Upper and Lower Limit Switch Prevents overwinding by stopping operation in the case of overlifting or overlowering.
Installed as a load detecting safety device to help prevent overload for greater hoist longevity.
Push Button Control
Compact design to enable one-handed operation. Rated NEMA 4 protection. Mushroom on/off button included. Push button cable has strain relief to prevent cable damage.
Electric Control Panel
Single speed hoists are re-connectable for 208-230-460 power supply. Controls are housed in a NEMA12 enclosure. Control transformer output is 115/1/60. Available in Variable Frequency Drive (VFD) for all motions. VFD is programmed for 2-speed operation. Standard power supply cord is 15 feet.
Heavy-Duty Hoist Motor
The hoist motor is a high torque design and is rated 30-minute duty. Class B motor insulation and standard thermal motor protection is included.
Load Sheave / Chain Guide
Full floating chain guide assures proper engagement of chain on load sheave. Features 4 or 5 pockets for better distribution of the load.
Grade 80 load chain is case hardened and has a high resistance to wear and corrosion. All hoists are stocked with 20 feet of lift. Longer lifts are available per requirement. Zinc galvanized load chain is available as an option.
Load hook is a forged carbon steel hook with a heavy-duty hook latch. Thrust bearing in hook allows 360˚ rotation to prevent twisting of load chain. Top hook, for hook suspended hoists, is rigid.
Chain container is standard equipment and is either molded with thick polypropylene material or fabricated from steel to securely contain the chain and chain lubricant. Optional containers are available for long lift applications.
Gear Box / Oil Lubrication
The gearbox utilizes an alloy steel helical and spur gear reduction. Gear
inspection and lubrication is easily accessible from the top of the hoist.
Trolley is adjustable for a range of flange widths. Motor includes disc type brake. Side guide rollers are included to promote smooth trolley motion and to minimize wheel and beam wear. Wheels are dual tread design for operation on tapered or flat flange beams. Trolley motor includes class B insulation. Motor is rated 15-minute duty and includes standard thermal motor protection.

Jib cranes are the most cost effective and versatile type of lifting equipment. They are great for use in production lines to keep machining cells, workstations and warehouse production moving. Jib cranes also work well to aid larger overhead crane systems. Jib cranes are easy to install and cost effective, with less structural limitations than other material handling options.
Follow these basic guidelines to help you choose the correct jib crane for your application:
Capacity: Choose a capacity that is right for current and future lifting needs. Most of the available options at JibCranes.com, up to 5 tons, include a 15% allowance for the hoisting equipment. This allows for full use of the rated jib crane capacity.
Span: Choose a span that is adequate to cover the full work area. Keep in mind that hoist and trolley selection may reduce the end approach, limiting hook coverage and requiring a move to a larger span.
Hook Height: The hook height is the height needed to lift your material. This measurement is equal to height under boom minus the headroom of the hoist and trolley.
Rotation: Jib cranes, depending on their design, have between 180° and 360° of rotation. Be sure that the area of installation is free of obstructions throughout the full range of rotation. Rotation stops are available upon request to limit the range of rotation.
Supporting Structure: When selecting a jib crane be sure to take into consideration the supporting structure. Building structures must be able to support the forces of the jib crane and load. Please, consult with your building designer or an engineer if uncertain of the adequacy of supporting structures. Also, keep in mind that the foundation requirements of freestanding jib cranes will add additional costs.
