From 5 Tons To 500 Tons: A Complete Guide To Crane Selection

Incorrect selection of cranes can lead to overloading fines, low efficiency and soaring maintenance costs. We will systematically analyze the logic of crane selection to help you precisely match your needs!

Chapter One: Selection by Tonnage

Small crane (under 10 tons)

This type of crane is suitable for lightweight tasks such as warehouse logistics, municipal engineering and agricultural operations, as well as space-constrained working environments.

Medium-sized crane (10 tons -25 tons)

Medium-sized cranes are widely used in construction sites, wind power maintenance and port handling, meeting the hoisting needs of most industries.

Large cranes (25 tons and above)

Large cranes are mainly used in heavy operations such as bridge construction, petrochemical projects and offshore platforms, and are reliable choices in complex environments.

Chapter Two: Selection by Structure

The truck-mounted crane has strong mobility and is suitable for logistics distribution and emergency repair operations, but its tonnage usually does not exceed 25 tons.

Truck cranes are convenient for relocation and have strong adaptability to different sites, but they have high requirements for the flatness of the foundation and are suitable for municipal engineering and equipment installation.

Marine cranes are specially designed for anti-corrosion and have excellent resistance to wind and waves. However, they need to be adapted to specific vessels and are commonly used in port loading and unloading as well as maritime rescue operations.

Dump trucks are suitable for transporting small-tonnage materials on construction sites, maximizing both efficiency and cost-effectiveness.

Chapter Three: Interpretation of Key Parameters - Avoiding Being Misled

Nominal tonnage and actual lifting capacity

It should be noted that the "maximum tonnage" marked by the manufacturer may only apply to the shortest arm state. BOB-LIFT promises that all parameters are marked with the real data under the most unfavorable working conditions.

The importance of the working radius

When choosing a crane, the working radius should cover the lifting distance and a safety margin of at least 2 meters should be reserved. For example, the operation of crossing a 15-meter obstacle requires a model with an arm length of no less than 18 meters.

Suggestions for power type selection

Diesel power is suitable for outdoor environments without power supply, electric models are specially designed for indoor and environmentally sensitive areas, while hybrid power strikes a balance between range and emission reduction requirements.

Chapter Four: Industry-Customized Solutions

Special machine for wind power hoisting

Equipped with a wind resistance level of over 7 and a wind speed warning system, it once helped a certain wind farm increase its installation efficiency by 40%.

Explosion-proof port crane

It has passed the ATEX certification and used copper alloy explosion-proof tools to achieve zero accident operation for three years at an oil and gas terminal in the Middle East.

Polar low-temperature version

The special hydraulic oil at -45℃ and the electrically heated cab were adopted and successfully applied in the construction of the Russian Arctic research station.

Chapter Five: Three-Step Quick Selection Method

Clarify requirements: Determine basic parameters such as lifting capacity, radius and environment.

Matching model: Use the BOBOB LIFT online selection tool for precise screening.

Verify feasibility: Apply for a 3D working condition simulation demonstration to ensure everything goes smoothly.
