MAST TYPE JIB CRANES
mast type jib cranes THE ECONOMICAL 360° SOLUTION
The MT Series Crane is floor supported, top stabilized,
and is capable of 360° rotation via a top and bottom
bearing assembly.
Three key requirements must be met before deciding
on a Mast Type Jib Crane:
1. An adequate structural support to stabilize the crane
    at the top of the mast must exist. If the jib is installed
    underneath an overhead crane runway or building
    truss, then the deflection of the supporting member
    may not exceed 1/2 inch.
2. Clearance overhead for the pivot assembly must exist.
3. Clearance overhead for the boom to rotate must exist.
AVAILABLE IN TWO STYLES
1) MT400 FULL CANTILEVER—provides for maximum
     amount of lift where full use of available headroom is
     desired.
2) MT450 DROP CANTILEVER—jib boom can be
     placed at a specific height to clear overhead
     obstructions.
MAST TYPE JIB CRANES ADVANTAGE
ECONOMICAL
mast type jib cranes advantage
• Simple, efficient design that usually requires no special foundation makes
   the Mast Type Cranes the most cost effective of the 360° rotation jib styles.
EXERTS LESS FORCE ON BUILDING STRUCTURE
• Exerts the least amount of force of any jib on its supporting structure.
SAFETY
• Utilizes a self-aligning radial bushing at the top which cannot be displaced,
   and an identical self-aligning radial bushing at the bottom which, used in
   combination with an oil-impregnated bronze thrust washer, provides ease
   of movement.
• Pre-Engineered for use with powered hoists. A factor of 15% of the jib crane
   capacity is allowed for the hoist and trolley weight with an additional 25%
   of the capacity allowed for impact, thus giving maximum capacity use of the
   jib.
PRODUCTIVE
• Allows full utilization of the working area with 360° rotation.
MAXIMUM TROLLEY TRAVEL
• Mast/beam connections eliminate the need for tie rods or knee braces found
  on competitive designs, thus permitting maximum trolley travel.
OPTIONAL POWER ROTATION
• (Features are shown below)
mast type jib cranes drawing mast type jib cranes cantilever The diagram left details the
thrust and pull forces that the
jib crane applies to the
supporting structure when
a load is lifted. It is essential
that a structurally adequate
wall or column exists to
support the jib crane.

FEATURES OF MOTORIZED CONTROL PACKAGE
mast type jib cranes motorized control package • Variable Frequency Drive (VFD) is standard.
The Variable Frequency Drive can be used in single or multiple speed
applications.
• Variable Frequency Drive provides the ultimate in load control.
The VFD provides the ultimate in load control and positioning from the
slowest possible creep speed up to maximum speed. The VFD is up to
25 times smoother than ballast resistor controls, does not produce
extensive heat, and enables precise starting and stopping.
• Easily adjustable speed control.
Through a simple keypad on the VFD, the acceleration rate,
deceleration rate and rotation speed can be adjusted to fit your application.
This allows you to customize the performance of the jib to your exact
requirements.
• Designed for indoor and outdoor use.
When being used outdoors, the cranes are designed to operate in
winds of 15 mph or less, based on a maximum load surface of 16 square
feet. Consult us for applications exceeding these standards.
The direct drive powers the rotation
of the Free Standing Crane. A speed
of 1/2 RPM is standard.
• Standard NEMA 4X Controls Enclosure.
mast type jib cranes control Standard controls enclosure meets the requirements for NEMA 3R,
12, 4 and 4X environments. Optional enclosures are available for other
environments.
• Low maintenance costs.
The VFD eliminates the need for magnetic reversing contractors,
reduces the number of wearable components in the panel, and reduces
long-term maintenance costs.
