Freestanding

Freestanding Jib Cranes require a foundation anywhere from 3 ft deep to 4 ft square and up to 5 ft deep to 11 ft square.  If columns or walls are not available, a Freestanding Jib Crane will provide an optimal range of capacity and span compared to a wall mounted or column mounted crane. 

Freestanding jib cranes have three installation capabilities:

  • A Standard concrete mount is a permanent installation
  • A sleeve mount installation allows for future relocation of the jib crane
  • A base plate mount requires extra space

IMPORTANT NOTE:

A SPANCO Free Standing Jib Crane is designed to be mounted to a permanent concrete foundation. The recommended foundations for a free standing jib crane are based on a soil pressure of 2,500 lbs. per sq. ft. It is solely the customer's responsibility to provide the proper foundation for the jib crane; there should be no deviation from the recommended foundation size without first consulting a qualified professional. The jib crane's boom or I-beam is designed to meet all specifications utilizing a 25% factor of rated load for impact and 15% of rated load for hoist and trolley weight. The pipe mast or column of the jib crane is designed to give maximum strength and minimum deflection to resist bending, buckling, and crushing, as well as wear by the trunnion roller assembly. The bearings in this jib crane are designed for a 5000 hour B-10 design life.

  • Air swivels
  • Collector rings

Case Studies

SPANCO - Jib Crane Helps Keep Food Redistribution Forklift Fleet Running Efficiently

One of the nation’s largest food redistributors manages a 275,000 square foot facility that is used as a redistribution hub for dry, frozen, and refrigerated food products. Due to the large volume of food products that are constantly moving in and out of the facility, the redistribution facility utilizes a large fleet of forklifts. These forklifts are subject to heavy usage and therefore require daily maintenance. The forklift fleet is serviced by the company’s maintenance department. Maintenance tasks include battery change outs, and pulling motors.

Because forklifts are a core component of the redistribution center, downtime due to maintenance can translate into a loss of profit. The maintenance manager had originally invested in a gantry crane to service the lifts. The gantry crane provided a solution for battery change outs, but became problematic when a motor needed pulled. Eventually employees resorted to using another forklift in combination with a come-a-long to aide in pulling the motor. This was not only requiring more manpower and another forklift, but it raised safety concerns as well.

Hoping to find a better solution for his department, the maintenance manager contacted a local SPANCO distributor. After evaluating the unique challenges and needs of the department, the SPANCO distributor recommended an investment in a large SPANCO jib crane. Eventually the maintenance manager decided to purchase a 3 Ton Motorized Freestanding SPANCO Jib Crane with a base plate mounted design. The jib crane has a span of 25ft with an under the boom height of 25ft.

Installation of the SPANCO jib brought immediate value to the maintenance department. Daily battery change outs could be done more efficiently and no longer required the presence of two employees. Now one person could handle the job. Complicated tasks like motor change outs that previously took as long as an hour and half with two employees and two forklifts could now be accomplished in 10 to 15 minutes. Improved turnaround times in the maintenance department started putting forklifts back on the facility floor quicker than ever before.
