Factory Crane Types:Factory Overhead Cranes & Gantry Cranes
How Does Your Factory Affect Crane Design & Installation

There are numerous factors to consider, including

• whether the load is liquid, filled barrels, solid items, or a moveable load?
• Are they special loads that needs special below-hook-devices or special safety features?
• What are the sizes or volume of loads? Long pipe, sheet or unique shape?
• And load wight that you needs to handle at a time?

Crane load, and crane lifting capacity

• Crane load is the most crucial consideration when buying an factory crane. Choosing the correct load level for an overhead crane will help maximize the equipment's performance and durability.
• What is the heaviest working load your factory crane will have to lift? When it comes to lifting large loads, safety is always the primary consideration. However, if you only need to lift 3 tons, there is no sense in spending a lot of money on a crane that can lift 10 tonnes.

The load unit is kilograms or tons. According to the specification "Design load - 5 tons," this crane has a maximum lifting capacity of 5 tons. This number should be determined based on the weight of the lifting object, the frequency of work, the job characteristics, or the intended use.

Load handling properly is essential for crane safety.

• Procedures for safe load handling are covered by the OSHA standard, including adhering to rated load limits, attaching loads, moving loads, and testing load limit switches. These requirements cover both the safety of the equipment and the duties of crane operators in safe crane operation. Please contact us for more information on crane load handling safety and regulations.

Span of factory overhead cranes

Factory crane span

The distance between the centers of two moving rails is measured as a crane span. The unit is meter (m). This parameter will be determined by the factory's actual size rather than a standard. Calculate the crane's aperture to be reasonable based on the width of the workshop to be designed. The lower the cost, the shorter the aperture, and vice versa.

Width of factory

The best factory overhead crane manufacturers will begin the quoting process by measuring the total width of the area where the crane(s) will be installed. The width measurement will include the building columns so that when approval drawings are made, you will have accurate information and will be able to maximize your space.

The overall width of this crane area, or the distance between the innermost portions of the building frames, will be examined by the project manager.

The third-party company will inspect the columns while taking measurements for your new overhead crane to look for problems, such as obstructions, piping, conduit, and any other attachments that could affect the placement of elements like the crane runway, among other things.

The person taking the measurements is essentially looking for anything that could have an impact on where the runway system's support columns are placed or the maximum height that can be used to clear overhead obstructions.

How building columns affect your factory width?What needs to know on your factory building columns?

The flange width of the column will be measured . In order to determine where the tiebacks for the floor-supported columns will be welded, they will also measure the flange thickness.Tiebacks will frequently need to be welded to the building column. A thickness check can help prevent unpleasant surprises during the installation process.

Tapered columns

When determining crane span for tapered columns, it is important to take into account the fact that the crane bay will become narrower as the columns rise.

Measurements for tapered columns differ from those for typical straight building columns. To determine the varying width differences between the top and bottom of tapered columns, it is better to measure to the outside of the columns.

Straight columns

It is much easier to measure the width of the bay if it is confirmed that the columns are the same width at the top and bottom. You'll need to know what the furthest point in on any width column is because it reduces the clear area you'll have to work with.

Obstructions and obstacles in your factory needs to be considered

• Main obstructions - any obstructions along the bay, around the general area of the crane, including from the floor to the roof, and looking through the crane area from one end to see everything as a whole, etc.
• Other obstacles to watch out for: low-hanging lights, overhead duct work, heater units, conduit running up the face of the column flanges, piping conduit, overhead ceiling fans, water supply lines, etc.

If there are any obstructions, they may need to be moved in order to attach and weld tieback braces to the faces of the building columns. The key to noting the presence of any of these impediments is to avoid surprises during or after installation.

For example, if your top unobstructed clearance is 20'2", the top of your factory overhead crane can only go up to 19'10".

The bridge crane must have a minimum of 3" of clearance over any moving objects, according to OSHA (Occupational Safety and Health Administration).

The crane's speed of lifting and lowering is typically designed in accordance with the manufacturer's specifications. There are typically the following categories: 1-speed, 2-speed, or variable speed are available. The cost of the finished factory crane will affectedd by the crane's speed. The most affordable crane is 1 speed factory crane.

Safety devices & Safety tips for your factory cranes

Safety devices

In comparison to traditional cranes, industrial use factory cranes not only needs to pass our factory acceptance test, but also enable our customers to run it in a safer manner with the following crane safety system configurations.

• Lifting limiter - The hosting organization must have a hoist limiter. The hoisting tackle can actively cut off the motor's power supply when it is 300 mm from the lifting organization rack, which causes the motor to stop working. It is the safety equipment used to stop two cranes from attacking on the same trajectory or for the crane to attack before reaching the end of its trajectory.
• Active Interlocking Equipment - The majority of the active interlocking equipment is located above the overhead bridge crane. Active interlocking equipment must be installed at the warehouse doorway leading to the driver's cab to prevent electric shock to maintenance personnel. The shock absorber is a safety device that absorbs energy when the crane collides with an object and acts when the crane brake and end switch fail. When the crane is connected to the track's end column, the crane will park more smoothly.
• Brakes - Brakes are devices that allow the lifting device to suspend operation at any time during lifting, translation, and rotation, as well as to keep heavy objects at any height. It can help to avoid accidents and meet job requirements. Because the effect of the brakes is so important for the crane, a malfunction of the brakes or claps is frequently the cause of the onset of many events.

Safety tips on crane factory

The following points should be noted during the operation of enterprises in factories with cranes:

• Train workers and technicians on how to use cranes safely and efficiently.
• To prevent damage and extend the lifespan of the equipment, perform routine cleaning and maintenance on the crane.
• When installing the factory crane, it should be installed at the top so that it does not obstruct the light, affecting the activities below and the lighting system.

What is the cost of a factory crane that will fully meet your needs after assessing all requirements? We strive to match overhead cranes to all budgets, regardless of size. For your convenience, the following factors which influence factory crane price are presented for your reference.

Total number of cranes

How many overhead cranes will be designed, constructed, and installed? Different types of factory cranes, lifting tools and approaches that can cut down on the number of cranes and equipment you might need to install, lowering your costs.

Crane capacity

The capacity of a crane, hoist, or below-the-hook lifting device refers to the maximum load that can be applied to it. In this way, every crane is special. The crane manufacturer is best suited to determine a crane's capacity because it is a variable that takes numerous factors into account. According to what they comprehend, they can assess capacity.

• The weight of the material that factory crane is going to lift
• The lifting devices or below-the-hook devices which will be attached and selected based on the loads to handle.
• Any other considerations for future need or lifting capabilities.

Numver of lifts per hour

Will your crane be operating at only 50% of its rated capacity, performing 2–5 lifts per hour? Or will it operate at or close to capacity, producing 4 lifts per hour each time? Your crane's duty cycle is an important factor in determining whether your lifting solution will meet your needs. The type of equipment you need will depend on the answer to this question, which is defined in crane classifications. While a lift system that doesn't meet your needs will wear out more quickly or may need to be replaced, over-engineering a lift will tie up capital.

Lifting height

The term "lift height" refers to how high your material needs to be raised into the air. Surprisingly, a number of factors must be taken into consideration when calculating your lift requirements, including:

• The shelves or racks that the material must be placed on,
• The elevation or height of any pits, boxes, or vehicles from which material will be lifted,
• Overhead obstructions,
• How the substance will be handled and WHY it will be moved,
• Elevation of an existing runway,

Power

Will the factory crane be powered by electricity, by hand, or by air (pneumatic)?

Operating speed

The faster the crane must operate, the faster its components wear out, so we must plan your crane use with this in mind. A process factory crane that performs 10-20 lifts per hour will require a faster bridge, trolley, and hoist than a large lift crane that requires precision but operates at slower speeds.

Working environment

The cost of an overhead crane will be affected by a tough, obstructed, or dangerous operating environment.

Environmental factors such as high heat, the presence of chemicals or fumes, steam, dust, or excess moisture can require the use of special metal coatings to protect and extend the crane's operating life. It may also require the use of specialized equipment or personal protective equipment (PPE) for installers during installation.

Obstructions can increase the cost of an factory overhead crane if installers do not have clear access to the area to remove or install an existing structure.

Runway locations

The existing environment has a large influence on the cost of a factory crane because it dictates what can be installed.

Some runway location issues that influence the cost of a factory overhead crane system are as follows:

• Is there already a runway in place? Is it strong enough to support the new crane structure?
• If a new runway system is required, will it be mounted to new support columns or tied back to the building?
• Is the flooring strong enough to support the crane's weight?

Support columns require a specific thickness of concrete to be placed on, cannot be placed over drains, or on cracked or broken concrete. We also need to take into account any wall or overhead obstructions that might require additional engineering and design considerations.

Span

Large-span cranes will require different engineering standards. Typically, the factory crane price will rise as the span widens.

And finally, never choose an overhead crane provider solely based on price! A factory crane system is a sophisticated and crucial piece of machinery used to increase the productivity, security, and efficiency of your company. It's worth the time and money to work with a crane company that understands your requirements and can provide an overhead crane system that will benefit your business in the long run.

The overhead crane installation process begins with the purchase of the overhead crane and ends with installation, guaranteeing project completion on time and within budget. Overhead crane installation will be on the agenda once you've decided which type of factory crane is best for your application, chosen a crane builder as your supplier, and signed the crane purchase agreement.

The general procedure of overhead crane installation are simply presented for your reference:

• Evaluation of the factory crane's work scope.
• Evaluation of crane installation site.
• Evaluation of potential hazards associated with crane installation.
• Evaluate the overhead crane runway system, both the existing and new runway systems.
• Crane installation must adhere to your timetable.
