Overhead Crane and Hoist FAQs
At Hoosier Crane we build and install a lot of overhead crane systems. We also sell a lot of overhead crane kits to customers who may never have built or installed a crane system before. One of our crane kit customers called us today looking for guidance in regards to installing the new overhead crane which he had just assembled from one of our crane kits. He wanted to specifically know how to set an overhead crane with a forklift. We thought that it would be a good idea to share with our other crane kit customers a few brief points on how to install a top running overhead crane with a forklift, so we put together this video of us installing a single girder overhead crane with a forklift.

Steps to Install an Overhead Crane with a Forklift
This job requires a trained forklift operator and at least one spotter, a scissor lift is also recommended for the spotter to safely be able to direct and position the crane onto the runway.
- Secure any dangling festoon wires that could become tangled or caught during installation with zip ties.
- Position your forklift on the beam side (opposite the festoon) of the overhead crane. Also be sure that you have the crane positioned with the collector staff towards the runway where your power bar will be.
- When positioning the forks they should be set as wide as possible.
- Begin near the center of the beam finding the center of gravity moving left or right as necessary. Slowly lift the forks once you have found the center of gravity so that the overhead crane balances evenly on the forks a few feet off the ground. Be careful that your hoist, hook or any other components of the crane are not in the way of the forks.
- With the overhead crane lifted a few feet off the ground with your forklift, have your spotter secure the beam to the forks with large C-clamps.
- With the crane secured to the forks, position the bridge crane diagonally between the runways such that the end trucks will clear the inside edges of the runway.
- Slowly lift the overhead crane with the forklift until the bottom of the endtrucks are above the rail of the runway system, with the spotter watching and directing to ensure clearance of runway and avoiding any other obstructions. Be aware of any overhead obstructions above the crane such as lights or sprinkler heads.
- Have the spotter direct the forklift driver to position the overhead crane moving it from diagonal to perpendicular to the runway system.
- From an elevated position the spotter should ensure the wheels of the endtrucks are parallel and are aligned with the rail of the runway.
- Once aligned, slowly lower the overhead crane with your forklift so that it just touches the rails of the runway.
- Have your spotter remove the C-clamps securing the forklift to the bridge beam and finish lowering the forks to the ground.
You are now ready to continue the installation of your overhead crane system.

Always wear appropriate personal protective equipment (PPE) when working with industrial equipment per OSHA guidelines.
Nearly all fall protection equipment is made of 4 key parts.
- The anchorage and anchorage connector - The anchorage is usually referred to as the tie-off point. An example of an anchorage would be an I-beam or an engineered fall protection system like a Gorbel Tether Track System.
- The anchorage connector - The anchorage connector is used to pair the connecting device to the anchorage.
- The connecting device - The connecting device is the link that joins the body wear to the anchorage connector. Examples are a retractable lifeline or a shock-absorbing lanyard (shown above).
- The body wear - The body wear is the protective equipment worn by the worker also known as a fall protection harness.

Hot Metal Hoists: Everything you Need to Know...
Hot Metal Handling hoists are held to different specifications than any standard duty hoist. If your crane is carrying hot or molten metal, it may be subject to additional safety standards per OSHA and ASTM.
Hot Metal Hoist Required Features:
- Power Circuit Upper Limit Switch that cuts the power to the entire hoist, opening up a disconnect switch. Most standard limit switches only cut power to the control circuit on the hoist.
- 8:1 Safety Factor on the hoist wire ropes. Standard safety factor is 5:1. Hot Metal Handlers require a greater safety factor due to the “loss of strength” from the heat.
- Secondary Holding Brake on the hoist load is required. Hoists typically come standard with one holding brake and oftentimes a control braking means. The secondary holding brake is a fail safe measure that maintains the load if the first holding brake fails.
- Trolley Safety Lugs are required to minimize the drop and hold the trolley in event of axle or wheel failure. Standard cranes only require safety lugs on the end trucks.
- External Locking Device on load-supporting bolts are required, such as cotter pins. Standard applications use lock washers and/or lock nuts.
- (3) Wraps of Rope are to remain on the rope drum when the hook has reached its lower limit. Standard hoists require only two wraps of rope.
- Warning Device such as bells, horns, sirens, or flashing lights are required to be activated when the crane is in motion. Any one or combination of these devices satisfy the requirements.
Note that Chain Hoists designed for Hot Metal Handling applications are left to the interpretation of these standards by the manufacturer. In our experience, it is typically not recommended to use Chain Hoists in a Hot Metal Handling application due to the exposure of the chain to high temperatures. The high temperatures can “re-temper” the steel load chain causing failure. In Wire Rope applications deformation in the rope occurs before failure, allowing preventative safety measures to be taken.
Please don't hesitate to give us a call or email us. We are happy to answer any of your questions or concerns regarding your hot metal carrying operations.
Hoosier Crane has all of the answers for your questions on Hot or Molten Metal Handling hoists. Give us a call!
Yes. According to the American Society of Mechanical Engineers (ASME) standard,B30.11 you need to have your maintenance and repair personnel certified to work on overhead cranes and monorails.
Revised in 2010, the most apparent change to the B30.11 standard is the addition of Chapter 11 – 4, “Maintenance Training and Maintenance.” B30.11-4.1 states, “Maintenance training shall be provided to promote proficient adjustments, repairs, and replacements on crane and monorail systems….”
This added chapter includes requirements for not only underhung crane and monorail maintenance training, but for certification as an underhung crane and monorail maintenance person. Certification is required for all persons who maintain and / or service monorails and underhung cranes.
Are you and your underhung crane and monorail maintenance personnel trained and certified?
If your answer is “no” and you are interested in becoming certified, please look at our crane school for more information on training.

Material load arrestors are redundant braking systems to the lifting apparatus. They are designed to prevent the lifted item from falling in the event of a failure in any part of a primary-lifting device. Load arrestors prevent damage to tools, equipment and products. Most importantly, load arrestors prevent employee injuries and fatalities.
Hoosier Crane is an advocate of load arrestors. We have designed, tested and installed systems in many manufacturing facilities and have seen them work time and time again.
We install two types of load arrestors. The simpler unit is a self-contained wire rope or synthetic web material reel with a spring driven realer and a speed-sensing device. It works like the seat belt in your vehicle. These units are typically used in capacities up to 500 pounds.
The second type is used for higher capacity loads up to 6,600 pounds. These load arrestors utilize an over speed device: a wire rope is attached at the top and a special type of speed-sensing/load-arresting device is attached to the item being lifted. A Blocstop Overspeed measures the speed of the wire rope as it passes through the load arrestor. Any speed over a pre-determined value will engage the load arrestor.
If a load arrestor engages once and prevents damage to equipment and products, the savings will pay for load arrestors for all your equipment. We can’t begin to calculate the value of protecting an employee from a falling load, but we are certain that it is more than the cost of a few load arrestors. If you are building a material lift, work platform or any of the other uses we have outlined in this article and have questions about load arrestors please contact us. One of our experience experts can help optimize your project for safety.

We have 3 reasons why our free standing jib cranes are better than the competition's.
1. Full gusset base plates
Other manufacturers typically utilize open gussets which can cause a warped effect.
Benefits of using full gussets:
- Stronger base to support the crane
- Less deflection at the tip of the boom
2. Large head size
Other manufacturers utilize a smaller head that can disfigure and damage the crane components leading to difficulty with the operation of the crane.
Benefits of larger head:
- Eliminates crushing of trunnion rollers
- Decreases deflection
3. Unique design of trunnion rollers
Prevents cutting into the mast, eliminating the need for a wear band. Other manufacturers use smaller trunnion rollers or cams that may actually carve into the pipe during rotation.
Benefits of these trunnion rollers:
- Ease of rotation
- No need for a wear band
Two types of trunnion roller assemblies are used:
- Type 1 - single formed channel and two rollers for mast diameters of 16" or less
- Type 2 - four rollers used for mast diameters of 18" or more
There are many factors to consider before selecting a jib crane.
- Know what type and the extent of structural supports you have available.
- Any current or future need for powered operation of the hoist or crane.
- The characteristic and design of each crane type.
- The overall height and height under boom offered.
- The relative cost of each jib crane type.
- The overall cost of installation.
Any new, used, or repaired hoist that has gone 12 months without use should be tested.
Make sure you test the hoist with no load, a regular load, and maximum load.
