General Jib Crane Design Criteria

The jib cranes shown in this catalog have been designed for general purpose indoor use in an industrial application using a hand chain or electric hoist where the live load plus the weight of the hoist trolley does not exceed the full load rated capacity plus 15 percent.

Structural components are designed and manufactured to meet or exceed the requirements of AISE and AWS 1.1 specifications.

Bearings are large capacity, pressure lubricated in precision machined housings designed for 10,000 hours average life.

Where applicable electrical components supplied by Mazzella Lifting Technologies are designed and wired in compliance with NEC requirements.

Exterior steel surfaces are power tool cleaned and sealed with one (1) coat rust inhibitive primer and two (2) coats of high impact resistant industrial enamel finish.

Jib Crane Model Descriptions

Manual Rotation
Motorized Rotation
Side Wall Traveling

Model WC: 200° rotation wall mounted compression braced jib crane. This model is the least expensive where maximum underclearance is required. Heavyduty GR50 steel construction with boom and vertical members reinforced with web gusset plates to provide greater strength and maximum resistance to torsional bending. Die formed fittings with pressed pressure lubricated bronze bushings and Timken® thrust bearings for maximum rotation ease. This style crane is suitable for mounting on a wall, column or any flat vertical surface structurally sound for design PULL and THRUST loading.

Model WCMB: This jib incorporates a WC model jib crane mounted on a self-supporting structural pipe base plate mounted mast.

Model WCMC: This jib incorporates a WC model jib crane mounted on a self-supporting structural pipe concrete insert mounted mast.

Model WT: 200° rotation wall mounted tension braced jib
       crane. This model is the least expensive for applications where overall height is not re-
               stricted. Heavy duty GR50 steel construction with boom a lower steel clevis which
                   clamps both sides of the boom providing true double shear and maximum resis-

tance to bending. Single and double tie rod design with National Coarse threads at each end for final leveling of boom at installation.

Die formed fittings with pressed pressure lubricated bronze bushings and Timken® thrust bearings for maximum rotation ease.

Model WC

Model Descriptions (continued)

Model WTMB: This jib incorporates a WT model jib crane mounted on a self-sup-porting structural pipe mast base plate mounted.

Model WTMC: This jib incorporates a WT model jib crane mounted on a self-sup-porting structural pipe structural mast concrete insert mounted.

Model SB: 360° rotation standard series self-supporting structural pipe mast base plate mounted.

Heavy-duty steel construction, incorporating lighter, stiffer sections, while maintaining a conservative stress criteria resulting in less deflection.

Jig fixture assembled to assure proper head, mast and bearing alignment.

Heavy-duty Timken head roller bearing with adjustable lower roller bearing assembly for boom leveling at final installation.

Model SC: 360° rotation standard series self-supporting structural pipe mast concrete insert mounted.

SPAN

Heavy-duty steel construction, incorporating lighter, stiffer sections, while maintaining a conservative stress criteria resulting in less deflection.

Jig fixture assembled to assure proper head, mast and bearing alignment.

Heavy-duty Timken® head roller bearing with adjustable lower roller bearing assem-
bly for boom leveling at final installation.

Model CT: 360° rotation axial floor ceiling mounted tension braced jib crane.

Heavy-duty GR50 structural steel mast supported top and bottom by high capacity self-aligning bearings. Bolted construction for ease of shipping and installation.

The top bearing connection may be secured to ceiling, overhead truss or with proper support bracket, from wall or column.

Model CB: 360° rotation axial floor, ceiling mounted tension braced jib crane.

Heavy-duty GR50 structural steel mast supported top and bottom by high capacity selfaligning bearings.

Model WT—200° Rotation

Model WT: 200° rotation wall-mounted tension braced jib crane. This model is the least expensive for application where overall height is not restricted.

Die-formed fittings with pressure lubri- cated bronze bushings and thrust washer for maximum rotation ease.

Single or double tie rod supported (depending on capacity and span) furnished with National Course threads each for final leveling at installation.
