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.

Below is a video with images for this recent project.  Enjoy!

Integrating Safety With An Overhead Crane System

Integrating Safety With An Overhead Crane System

When a large aviation client asked Crane-Tec to build an overhead crane system, the safety of their employees was paramount to the design.

34 percent of injuries and many work-related deaths are the result of a fall from height.

We understood that taking a preventative stance to protecting employees from injury or death, and to remain compliant with OSHA standards, was an important element to this job, so we sought out an industry leader to help with the design.

SOLUTION

Crane-tec turned to Rigid Lifelines, a company at the forefront of fall prevention safety, to help incorporate a Rigid Track fall prevention system into the overhead crane design.

We engineered the safety equipment right into the monorail system that we designed and then built all of the structural steel and the system to support everything.

RESULT

  • The installed overhead crane system consisted of a 20 metric ton crane with 15 ton monorail spurs. Fall protection rail was installed on each of the 18 monorail spurs and the bridge crane
  • Each 58 foot long monorail spur had its own fall protection rail designed to support two people
  • On each system there were two, self locking trolleys with retractable lanyards

The purpose of having the fall protection secured into the structural support of the crane and monorail systems is to protect the personnel when they’re working on the large engines.

Next month we’ll highlight this entire project and showcase the cranes and hoists provided by our partners at EMH.  Stay tuned!

 

Down with the OLD, Up with the NEW

 

 

 

The Challenge:

Remove two old 10 Ton Top running double girder cranes and replace them with two new 10 ton top running single girder cranes.

 

 

 

 

 

 

Special Considerations:

  • The New single girder cranes needed to have the same amount of lift as the old double girder cranes
  • New cranes could not have any painted surfaces that could chip or flake (Note: clean room environment)
  • Precise hook spotting required for accurate hood positioning

 

Our Team Approach:

  • Our team, armed with existing building dimensions, designed a stooled up single girder crane with a close headroom hoist to meet the lift requirements.
  • The hook and lower block of the hoist were disassembled, sand blasted, and reassembled.  The running surfaces on the bridge beam were kept bare metal.
  • A four light state of the art hook positioning system was installed on the hoist to indicate the exact lifting point

Result:
The old cranes were removed and the new cranes installed with little to no interference to the customer production time.

 

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

                                

 

John Deere Dealer Crane

The Challenge:

To provide our customer, a John Deere Dealer, with an integrated crane system for a new facility in Indiana.
The project incorporated two 5-ton underhung cranes and runway systems.

Special Considerations:

The general contractor needed design loading for the building and runway system. Single girder cranes with low headroom hoists were used to minimize runway and building steel costs.

Crane-Tec engineers using the metal building drawing, designed a cost efficient and space saving runway system using the building frames to suspend the runway system. This maximized the strength of the building.
Both cranes were supplied with radio remote controls for safe and precise operation.

Results:

Crane-Tec supplied a complete engineered crane and runway system. The crane system was installed, weight tested, and turned over to the owner on time with a two year warranty.

 

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.

Results

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

 

Warehouse Expansion Case Study

 

 

 

The Challenge:

To provide our customer, an electric motor manufacturer, with an array of lifting solutions for a large expansion of their facility.

 

Special Consideration

Our customer needed to be able to move large scale electric motors throughout their facility interacting with multiple workstations.

 

Our TEAM Approach:

We worked closely with the customer to learn their specific needs, workflow and expectations, which resulted in the following:           

  • Installing Two 25 Ton top running double girder cranes with a radio control system that allows the cranes to be operated in unison, or individually, with only one hand held remote.
  • Installing eight 1-Ton column mounted jib cranes with electric two-speed chain hoists.
  • Installing a 2-Ton floor mounted jib crane with an electric two-speed chain hoist.

Result:

We provided our customer with a state of the art lifting system solution that maximized their workflow and productivity and was installed on-time and within budget.

 

Vacuum Lifter Case Study

 

The Challenge:

To provide our customer, an industrial metal parts stamping facility, with a safer and more efficient way to load their laser cutting machine.

Special Considerations:

Our customer needed to be able to load the machine with a large piece of sheet metal quickly and safely.  The machine was in a current manufacturing facility which had low ceiling clearance.

 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:

  • Using the existing building trusses to support a Spanco underhung push-pull bridge, trolley and runway system

  • Installing an R&M electric two speed chain hoist

  • Using an Anver vacuum air lifter with built-in air compressor to lift the sheets with ease.

Result: 

Crane-Tec’s highly skilled installers installed a state of the art lifting system in just under 24 hours, keeping our customer’s production staff with minimal down time. They are now able to load the machine more safely and efficiently.

 

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.
