The Guide To Choosing A Truck-mounted Crane Lies in Five Key Parameters

A customer once chose the wrong crane model, resulting in:

The actual lifting capacity was insufficient, forcing a secondary purchase

The axle load exceeds the standard and cannot be registered for annual inspection

The hydraulic system frequently malfunctions, and the maintenance cost exceeds 100,000 yuan

If you also don't know how to choose the right crane, we will help you make a wise choice.

Chapter One Lifting Capacity: It's not the case that the greater, the Better

1.1 How to calculate the real demand?

Formula: Maximum single lifting capacity = Object weight ×1.2 (Safety factor)

Case: A certain logistics company often transports 18-ton equipment. It should choose a model of ≥22 tons (18×1.2=21.6).

1.2 Be vigilant against "False Labeling"

Industry chaos: Some manufacturers label the "maximum lifting capacity" as the data under the lowest arm span

BOB-LIFT promises: All marked parameters are under the most unfavorable working conditions (full arm extension + maximum radius)

Chapter Two Working Radius: Determine Your Scope of Work

2.1 Comparison of arm length vs. coverage range

Arm length 12 meters: Horizontal coverage radius 9.5 meters, suitable for community greening/warehouse loading and unloading

Arm length 18 meters: Horizontal coverage radius 14 meters, suitable for steel structure factories/logistics parks

Arm length 24 meters: Horizontal coverage radius 19 meters, suitable for port container/wind power maintenance

2.2 Special Working Condition Solutions

Narrow space: Select folding arms (such as the BOBOB LIFT K series with a joint Angle of 270°)

Obstacle crossing: Install a flying arm (extending 3-5 meters)

Chapter Three Power Types: Diesel vs Electric vs Hybrid

3.1 Comparison of Three Types of Power

Diesel: It has strong power, no range anxiety but is noisy and its emissions are restricted

Electric: Zero emissions, usable indoors but with a battery life of 4 to 6 hours

Hybrid: It strikes a balance between environmental protection and range, but the price is 30% higher

3.2 Selection Suggestions

Urban operations: Electric (such as the BOBOB LIFT E-25 silent version)

Field construction: Diesel (DPF exhaust gas treatment is recommended)

Chapter Four Axle Load Distribution: The Core of Blue Card Compliance

4.1 Hard Indicators for the registration of truck-mounted cranes

The total mass is ≤18 tons

Single-axle load ≤10 tons (the rear axle is usually double-axle)

4.2 Over-limit Risk

A fine of 5,000 to 30,000 yuan is imposed

The insurance refused to cover the accident losses
