Crane Truck Hire Limits: Factors That Affect your Maximum Lifting Capacity 

July 2023

Crane trucks have become indispensable in various industries, offering unmatched lifting capabilities and efficient material handling solutions. From construction sites to logistics operations, these powerful machines play a crucial role in accomplishing heavy-duty tasks. However, as with any heavy equipment, understanding and adhering to the crane truck's maximum lifting capacity is paramount to ensuring safe and successful operations. 

What Does Maximum Lifting Capacity Mean? 

Maximum Lifting Capacity refers to the maximum weight that a crane truck can lift safely and efficiently under optimal conditions. It is typically measured in metric tons (MT) or imperial tons (tons) and is a crucial specification that determines a crane truck's capabilities. This capacity includes the weight of the load and any additional equipment, such as rigging, slings, and hooks. 

The lifting capacity is determined by various factors, including the crane truck's design, hydraulic systems, and structural integrity. Manufacturers carefully engineer crane trucks to handle specific weight ranges, and it is essential to understand and adhere to these limits to ensure safe operations and prevent potential accidents.

Factors Affecting Crane Truck Maximum Lifting Capacity  

Understanding the crucial elements that influence crane truck maximum lifting capacity is essential for safe and successful material handling operations. 


  • Boom Length and Configuration 

The boom of a crane truck is a critical determinant of its lifting capacity and reach. Different crane trucks come with varying boom lengths and configurations, which directly impact the crane's ability to lift loads at different distances from the truck. 

In the Australian construction industry, where access to confined spaces and complex worksites is common, crane trucks with telescopic booms are favoured for their ability to extend and retract, providing flexible reach capabilities. 


  • Load Distribution and Center of Gravity  

In crane truck operations, ensuring proper load distribution is vital for maintaining stability and safety. Improper load distribution can lead to uneven weight distribution on the crane, affecting its lifting capacity and potentially causing instability during lifting operations. It is essential for operators and businesses to carefully plan and execute load distribution to ensure the load is evenly balanced and secured. 


  • Terrain and Ground Conditions  

The terrain on which a crane truck operates significantly influences its lifting capacity. Uneven, sloping, or rough terrains can impact the stability of the crane, affecting its ability to lift heavy loads safely. Operators must consider the terrain and plan their lifting operations accordingly, ensuring the crane is set up on stable ground. 

Soft or unstable ground conditions present unique challenges for crane truck operations. In such conditions, the crane's outriggers or stabilisers may sink into the ground, compromising stability and lifting capacity. Adequate ground preparation and the use of stabilising mats or cribbing materials are essential to mitigate these challenges and maintain safe operations. 


  • Crane Positioning and Boom Angle  

Proper crane positioning is crucial for safe and efficient lifting operations. The crane must be positioned in such a way that it has optimal access to the load and can maintain a stable foundation throughout the lifting process. Skilful crane positioning ensures that the load is lifted smoothly and minimises the risk of accidents or damage to the crane. 

The boom angle refers to the angle of the crane's boom in relation to the horizontal plane. The lifting capacity of the crane truck can vary depending on the boom angle. Operators must consider the boom angle during lifting tasks to ensure that the crane's capacity remains within safe limits. 


  • Weather and Environmental Factors  

Weather conditions, especially wind speed and gusts, can significantly affect the lifting capacity of a crane truck. Wind exerts lateral force on the crane's boom, reducing its overall capacity and stability. Operators must monitor wind conditions and adhere to specific wind speed limits for safe lifting operations. 


Importance of Safety Protocols in Crane Truck Operations 

Safety is the cornerstone of every crane truck operation. Adhering to rigorous safety protocols ensures the well-being of personnel, safeguards valuable assets, and prevents potential accidents.
