Product Announcement from Gorbel Inc.


Aluminum Tie Rod Work Station Jib Cranes -Image

The tie rod design minimizes deflection and is more precise when positioning loads than other Jibs Cranes.

  • Can be mounted to wall or column
  • Available in capacities from 150 - 2000 lbs. with spans up to 20 ft.
  • Has less deflection for easier load control and positioning

Features:

  • Can be bolted directly to your existing floor without adding special foundations
  • Feature a retaining pin through the pivot pin to help resist accidental upward dislodgement of the boom assembly
  • Capacities from 100 to 1000 lbs.
  • Spans to 16ft.
  • 360° rotation

Use for:

  • Circular areas not sufficiently covered by a main crane
  • Supporting tool balancers, air balancers, hoists, vacuum lifters and welding wire feeders

Local Representation - Gorbel® Jib Cranes are sold and serviced through a network of experienced material handling specialists through North America, China, Korea, and Australia

Versatility - Gorbel makes a complete line of jib cranes to meet your needs!

Safety - All cranes are pre-engineered for powered hoist operation - with a factor of 15% of the jib capacity for the combined weight of the hoist and trolley and an additional factor of 25% of the jib capacity for the impact of powered hoists.

Available Accessories:

  • Festoon Clamps - Festoon clamps anchor the festooning at the start of the jib boom. They also prevent the festoon gliders from exiting the track and they can provide a redundant stop for the trolley. Festoon clamps for vacuum hose are also available.
  • Festoon Gliders - Festoon gliders are used to support flat electrical cable along the jib boom. No tools are required to attach the festooning to the gliders. One festoon clamp is required with the use of festoon gliders.
  • Festoon Trolleys - Gorbel® festoon trolleys are used to support flat cable, air hose, or round cable along the jib boom. The trolleys have four wheels and a pivoting festoon saddle support. Festoon trolleys for vacuum hose are also available. One festoon clamp is required with the use of festoon trolleys.
  • Flat Cable and/or Air Hose - A flat cable festooning system is required when using an electric powered lifting device. Air hose is also available and is supported by festoon trolleys.
  • Four Ring Electrical Collector (Top or Bottom Entry) - A collector is needed to provide a continuous 360° boom rotation when using an air powered lifting device. A bottom entry collector requires 4 additional inches of clearance above the pivot pin. A top entry collector requires 11-1/4 additional inches of clearance above the pivot pin.
  • Air Swivel (Top or Bottom Entry) - An air swivel is needed to provide a continuous 360° boom rotation when using an air powered lifting device. A bottom entry air swivel requires an additional 5 inches of clearance above the pivot pin. A top entry air swivel requires between 8-1/2 and 9-1/2 inches (depending on span and capacity) of additional clearance above the pivot pin.
  • Manual Rotation Stops - Rotation stops are required to limit the WSJ360 rotation to less than 360° to prevent boom damage to machines, equipment, or building structures.
  • WSJ360 Portable Base - a portable base is required to allow a WSJ360 to be lifted with a lift truck and transported to multiple locations.
  • Vacuum Platform Attachment - If a vacuum lifted motor/blower is required to be mounted on the mast or building column, then a specially-designed vacuum blower support platform attachment can be designed for this specific application.

Anchor Bolt Load: The total amount of force that is applied to each supporting anchor bolt; usually measured in kips.

Axial Load: The total vertical force applied to the supporting structure.

Formula: Axial load = (overall weight of the crane) + (design factor x weight of load)

Boom: The horizontal beam (track) upon which the hoist trolley travels. The "jib" of the jib crane.

Bracket Center: The distance, center line to center line, between two supporting brackets of a wall mounted jib crane (i.e. the distance between the two wall mounting points).

Capacity: The maximum live weight that the crane is designed to support. For jib cranes, the design load is based on the capacity, plus a hoist and trolley allowance (15% of capacity) and an impact allowance (25% of capacity). The allowable deflection of the crane is calculated using the design load plus the hoist allowance. Load testing can be performed to 125% of rated load capacity. Standard Gorbel® jib cranes are available in capacities up to 5 tons (4536 kg).

Deflection: The difference in elevation at the tip of the boom between an unloaded crane and a fully loaded crane; usually measured in inches. Gorbel tends to have stricter deflection criteria than others in the industry.

Foundation: Free Standing jib cranes require that a special foundation, usually of concrete and steel, be used to support the crane and prevent the crane from tipping over. Foundation recommendations can be found in the price pages and in the installation manual.

Height Under Boom (HUB): The distance from the floor to the underside of the crane's boom. The minimum height under boom equals the height of the load, plus the maximum distance the load is to be lifted, plus the headroom required for the hoist, trolley, and attachments.

Mast: The vertical steel component of the jib crane which supports the crane. Free Standing jib cranes (including Work Station Jibs) have a circular pipe for a mast.

Overall Height: The distance to the highest point on the jib crane (should include hardware). A minimal clearance (nominally 3 inches) is required from any obstructions above the boom or tie rod assembly throughout the entire rotation of the crane.

Span: For a jib crane, span is the distance from the center of the pivot point to the end of the boom. Note that "span" is greater than actual "working span" or "hook coverage."

Supporting Structure: For a free standing jib crane the supporting structure is the foundation which the crane is bolted to or implanted in. For a wall bracket or wall cantilever jib crane, the supporting structure is the wall or column to which the crane is bolted.

Thrust and Pull: Forces exerted by a crane on its supporting structure. Thrust is the pushing (or compressive) force exerted on the structure, while Pull is the tensile force. Thrust and Pull are thus equal (but opposite in direction) to each other. The maximum thrust and pull occurs when the crane is loaded at full capacity.

Working Span: The working span (or hook coverage) is less than the span of the crane. It is a function of the maximum hook reach and the ability to get the trolley close to the mast.
working span = (distance between trolley stops) - (hoist trolley length)

Features:

  • 200° rotation
  • Capacities to 1000 lbs.
  • Spans to 16 ft.
  • Can be mounted to wall or column
  • Uses tapered roller bearings at the pivot points for unsurpassed ease of rotation
  • Shim stock up to 7/32" is included with each jib to ensure that the jib is aligned through the pivot axis and thus avoid unwanted drifting of the boom

Use for:

  • Servicing circular areas
  • Supporting tool balancers, air balancers, vacuum lifters, and hoists
