Long Span Cranes

Prefabricated metal buildings are increasingly moving towards widespan bays.  This requires overhead crane systems that have longer spans and heavier lifting capacities.  In addition, many considerations come in to play when designing and engineering long span crane systems in prefab buildings.  We have the knowledge and expertise to guide our clients towards the safest, most efficient solutions.

Here’s a glimpse in to one of our most recent jobs in a prefabricated metal building:

 

Special Considerations:

  • Overhead crane with span over 60 feet requires fabricated box girders
  • Long span cranes take up a large amount of the height in the building
  • Trucking and installation require special considerations and know-how

 

Our Team Approach:

  • Our team of engineers developed programs to design box girders for crane spans up to 110 feet
  • Our fabrication facility has the box girder weld tables and automated welding equipment to fabricate box girders to 110 feet
  • The Installation crew developed procedure and safety standards for handling long span box girder
  • Crane-Tec uses low head room trolley design to maximize building height

[Crane-Tec Runway Systems with spans up to 90 feet.]

 

Results

Cranetec has mastered the ability to engineer, fabricate, and install long span cranes at a very cost effective price.  We also do complete startup and testing of the installation for maximum efficiency and safety.

Providing Solutions for Plastic Products Industry

Providing Solutions for Plastic Products Industry

Crane-Tec worked our magic again when a large international manufacturing company asked us to build and install a 15-ton top running double girder crane that will operate on an existing 10-ton capacity runway system.  Here’s what we came up with:

Special Considerations:

  • The existing runway system is designed for 10 ton.
  • The lifting height of the new 15-ton crane can be no less than the existing 10 ton crane.

Solution:

Crane-Tec’s team collected information on the existing 10-ton crane and runway system and our engineer offered two solutions:

  • A 15-ton top running double girdle crane with a low headroom trolley hoist and a 15’-0” end truck wheelbase. The wheelbase was calculated to not overload the existing 10-ton runway system.
  • A 15-ton top running double girder crane with a low headroom trolley hoist. The trolley hoist has load limiters and travel limiters to restrict the 15-ton load to the center one-third of the crane span. The rail-side one-thirds are limited to 10 ton.

[Our engineers design to your specific needs.  That’s what sets us apart!]

Results:

The customer selected solution #1.

Crane-Tec furnished, installed, and tested the new 15-ton top running double girder crane with low headroom trolley hoist and a special 15’-0” wheel base on time.

 

Precision Needed For Railroad Engines

Crane-Tec was called upon to do a project for a Railroad Engine Maintenance Facility.  Our team of experts were asked to engineer, build and install a free-standing, 20-ton crane system in an existing facility.  This new setup would be used to service railroad engines.

 

Special Considerations:

  1. The customer’s application required precise movement and positioning
  2. Adding a freestanding runway system into an older, existing building.

 

Solution:

Working with the customer and general contractor requirements, Crane-Tec engineers designed a freestanding, 20-ton crane system.  We recommended variable speed control for the bridge, trolley and hoist.  We also added a true vertical lift hoist.

[Our engineers design to your specific needs.  That’s what sets us apart!]

Result:

Crane-Tec engineered, built, installed, and tested the complete 20-ton top running double girder, heavy duty, radio remote controlled crane and free standing runway system.

How do you make a frog

The Challenge:

To provide a building supported crane system with two 25 Ton capacity and one 10 Ton capacity long span heavy duty cranes.  The crane system was to be designed into the metal building structure of a regional railroad manufacturer for their “Frog” manufacturing.  Frogs are railroad exchanges that divert trains from one line to another.

Special Considerations:

Owner application required heavy duty high speed cranes.  Independent tie back runway systems were designed to maximize the strength of the pre-engineered metal building.

Our Team Approach:

Working with the owner and the General Contractor we were able to design a building that supported the loads of 3 heavy duty high speed bridge cranes.  We installed two 25 ton cranes, each with a 5 ton auxilliary hoist, and a 10 ton crane.  These allowed the manufacturer to have three work areas which stream-lined their manufacturing.

Results:

Crane Tec supplied a turn-key crane system on time and within budget

                                

 

Wooden Building – Crane Installation

The Challenge

To provide our customer, a custom wooden structure and joinery fabricator, with a system that would improve production times and allow them to move large pieces of material safety and more efficiently.

Special Consideration

The company’s production is located in a very unique and
stunning facility made completely out of wood. They needed the ability to load large pieces into milling machines and move finished products
throughout the building.  Crane-Tec was challenged with designing a structural system that worked within their wooden building framework.

Our Team Approach

Crane-Tec worked closely with the customer to learn
their specific needs and expectations of the new system.
With our combined efforts, and after reviewing several options,
solutions included:

  1. Two 2.5 Ton top running single girder cranes.

  2. Radio control operation for each crane, with the option to operate each crane individually, or in tandem. This feature allows the operator to link both cranes together and operate them simultaneously with one single button push, ideal for handling of long pieces of materials.

  3. Special anchors to attach the crane’s steel runway beam to the wooden building haunches.

Results

Crane-Tec delivered a system that exceeds the customer’s expectation and allows them to easily and safely move products throughout their amazing facility.


 

Dual 25 Ton Cranes Case Study

The Challenge

 To provide a crane system to help our customer in their manufacturing of large concrete building panels.

Special Consideration

Our customer needed to move large concrete panels through their high capacity manufacturing process.

Our Team Approach

We worked closely with the customer to learn their manufacturing process, their material handling frequency and their performance expectations.  This resulted in the following:

  • Engineering, design, and installation of

    – Crane runway beams and crane rail on their existing concrete column haunches

    – Two (2) 25 ton top running double box girder cranes

    – Engineered lifting beams to facilitate movement of the large precast panels

  • Cranes were sized for heavy duty usage with high speed hoists, trolleys and bridges.

  • Cranes were equipped with radio remote controls for safe and efficient material handling. The remotes allowed the customer to operate the cranes individually and in tandem.

Results

Crane-Tec provided our customer with a complete turnkey crane system that was customized to their manufacturing needs.

 

Injection Molding Facility Case Study

The Challenge:

To provide
our customer, an injection molding facility, with a larger capacity crane to fit an existing runway system. The customer was upgrading their facility with larger machines and wanted to add  a 7.5-ton top running crane to their existing 5-ton system.

Special Considerations:

The existing crane, being lower capacity, had a shorter stature on the runway rail. With the customer needing a specific lifting height capability, and the building having a low roof, our engineers and staff were up to the challenge.


Our TEAM Approach:

Crane-Tec worked closely with the customer to learn their specific needs and expectations of the new system. With our combined efforts, many options were presented, including:

  • A double girder crane, which allows the use of smaller beams to achieve the low headroom hook height.

  • Radio control operation which allows the operator to stand at a safe distance from the load and move through the factory freely. 

  • A goose neck connection from beam to end truck to maximize lifting height.

  • Duel hoist to aid in larger lifts and rotating molds for service.

  • A warning light and buzzer to alert others in the building the crane is in motion.

Result:

Crane-Tec delivered a custom built, state of the art crane.  Following up with our customer, our staff was told with this new system, mold change down time has been cut by 2/3.
