Why are counterweights important for mobile cranes?


A mobile crane is a vehicle-mounted crane that is designed to lift and maneuver heavy loads in a variety of different industries and applications. There are mobile cranes for any weight that is more than what can be safely lifted or moved by a human. Counterweights are the weights either built into the body of a crane or applied additionally, that stop the crane from falling over when it is lifting an item.


Why are counterweights important?
Counterweights are extremely important when it comes to the engineering of a mobile crane or the planning of a lift. They are integral to ensuring that the crane remains stable and does not topple over during a lifting operation.  Without the counterweights on a crane, it wouldn’t be able to lift it’s capacity.


What can happen if a counterweight is not used correctly?
In short if a counterweight is not used correctly, a crane can fall over either during the lift or as it lets go of its cargo. During a lift, if the counterweight is insufficient to balance the load that the crane is lifting, the crane can topple forward in the direction of the boom.

If the counterweight is too heavy for the weight of the boom, the crane is travelling up an incline or outriggers are not extended, the crane can topple backwards. If the ground conditions are uneven and you have not set the crane up with appropriate counterweights, the crane can also topple backwards.

Counterweight design is not just about the weight; the size and shape of the weight are also important. Engineers design mobile crane counterweights for the specific type of crane it is being used with to prevent crane accidents.


What are crane counterweights made of?
Our counterweights are made of cast iron, the safest material for counterweight design. Cast iron counterweights are small, but because of their density, they provide enough weight to balance out even the most massive loads. Our counterweights are inspected regularly to ensure their structural integrity and durability.


Mobile Crane Safety
Preventing Mobile Crane accidents is of utmost importance to us at Lindores Mobile Cranes. Miscalculation of loads and the need for counterweights is the most common reason for crane accidents. Our team is meticulous when it comes to load planning and site inspection - and we do this to avoid accidents. We use our experience, combined with mathematical calculations and crane manufacturer guidelines to ensure that the counterweights applied are appropriate for each load that our cranes lift.

All of our cranes come with crane load charts which we use to plan our lift plans in each and every lift that our cranes do. Crane load charts provide the information needed to ensure that the right counterweights are applied, the boom angle is appropriate, and the vehicle is configured for maximum safety.


What cranes use counterweights?
All cranes have counterweights including mini cranes, they are actually built into the crane.  Mini cranes and city cranes do not tend to need or warrant the use of extra counterweights. A Franna Crane Superlifter carries a counterweight with it at all times on the front of the crane and then uses extra counterweights to classify as a superlifter, lifting up to 28 tonnes. Mobile slew cranes use counterweights as a standard practice, all lifts are different so therefore the calculations of the amount of counterweight needed is all different.


Lift Planning
We also make sure that our clients use the right crane in the right situation. Sometimes a two crane lift will provide better stabilisation and safety than a larger crane with counterweights. Our experience and diversity in our fleet means that we can make these decisions with confidence, giving you the safest lift possible.

Operating mobile cranes is a critical part of many construction and industrial projects, but it comes with significant risks. Mistakes in crane operation can lead to project delays, equipment damage, or even serious injuries. At Lindores Mobile Cranes , safety and efficiency are at the core of what we do. Below, we’ll explore some of the most common mistakes in mobile crane operation and share how our team actively mitigates risks and prioritises safety on every lift. 1. Improper Site Inspection The Risk: Failure to assess the job site properly can result in uneven ground, insufficient clearance, or interference with nearby structures or power lines, all of which increase the risk of accidents. Our Solution: Lindores Mobile Cranes conducts thorough site inspections before every project. Our experienced team assesses the terrain, identifies potential hazards, and ensures the site meets all safety requirements. This proactive approach minimizes risks and ensures smooth operations from the outset. 2. Exceeding Load Capacities The Risk: Overloading a crane beyond its capacity can compromise stability, leading to equipment failure or tipping accidents. Our Solution: Our team rigorously calculates load weights and matches them with the crane’s capacity. We use advanced load-monitoring systems to double-check weight distributions in real-time. Additionally, our operators are fully trained to understand and adhere to each crane’s load chart. If necessary, we use multiple cranes to lift objects, ensuring sufficient lifting capacity and safe weight distribution. 3. Neglecting Proper Equipment Maintenance The Risk: Poorly maintained cranes are more prone to mechanical failures, which can cause downtime or dangerous malfunctions during operation. Our Solution: At Lindores Mobile Cranes , regular maintenance is non-negotiable. Our cranes undergo routine inspections and servicing by qualified technicians. We maintain detailed maintenance records and replace any worn parts before they become a problem, ensuring our equipment is always in peak condition. 4. Inadequate Operator Training The Risk: Untrained or under-qualified operators may misinterpret signals, improperly maneuver loads, or fail to respond correctly in high-pressure situations. Our Solution: We only employ certified and highly experienced operators. New employees receive consistent and thorough training and mentorship from senior members of our team, to ensure they uphold our high standard of service and operation. Additionally, our team is continuously trained and updated on the latest industry standards and safety protocols. 5. Ignoring Weather Conditions The Risk: Operating a crane in high winds, heavy rain, extreme temperatures or low-visibility heightens the risk of accidents, equipment damage and load instability. Our Solution: Weather conditions are always factored into our planning process. If conditions are deemed unsafe, we communicate transparently with our clients to reschedule operations. Our priority is always safety. 6. Failure to Use Proper Rigging The Risk: Improper rigging or using damaged lifting equipment can result in dropped loads, endangering workers and equipment. Our Solution: Our team is trained to select and inspect the right slings, shackles, and hardware for each lift. We follow strict rigging protocols to ensure every load is secure and balanced before lifting begins. 7. Poor Communication on Site The Risk: Miscommunication among team members can lead to errors in load handling, positioning, or crane operation, increasing the likelihood of accidents. Our Solution: We prioritise clear and consistent communication on all our job sites. Our operators, riggers, and ground crews use standardized hand signals and two-way radios to stay in constant contact, ensuring everyone is on the same page. Why Choose Lindores Mobile Cranes?

Heavy lifting with Mobile Cranes requires efficiency, safety and precision. Often lifts involve oversized or irregularly shaped loads, which require some creativity to lift effectively. Dual lifts are one of our favourite techniques for manoeuvring difficult objects. In this process, two cranes work in tandem to lift a single object. As experts in the field, our team routinely execute dual lifts with unparalleled precision and safety. Here’s why dual lifts are an essential technique in the mobile crane industry and how they deliver exceptional results for complex lifting operations. The Utility of Dual Lifts Using two cranes in tandem significantly increases the total lifting capacity, allowing us to handle much larger and heavier loads than a single crane could manage. Certain loads, such as those with unusual dimensions or weight distributions, can be unstable when lifted by a single crane. With a dual lift, the weight is distributed across two cranes, improving balance and reducing the risk of the load tipping or swinging. Dual lifts can also be essential for situations where the load must be navigated through tight spaces or lifted at an angle. The coordination between two cranes provides greater flexibility in guiding challenging environments. The Effectiveness of Dual Lifts Safety is a top priority in any lifting operation. By distributing the load between two cranes, dual lifts reduce the strain on each crane. At Lindores Mobile Cranes , every dual lift is planned with rigorous attention to detail to ensure the safety of operators, equipment, and the surrounding environment. Dual lifts can also save time on complex projects. Instead of dismantling large loads into smaller pieces for single-crane lifts, a dual lift can handle the load in one go, reducing operational delays and increasing project efficiency. Finally, while dual lifts may seem like a more resource-intensive approach, they can ultimately save money by reducing project timelines, preventing damage to sensitive loads, and avoiding the need for additional equipment or labour. Dual lifts with mobile cranes are a versatile and effective solution for handling complex loads. By leveraging the combined strength of two cranes, this method ensures safety, efficiency, and cost-effectiveness for projects across various industries. If you’re tackling a challenging lift, trust the experts at Lindores Mobile Cranes to deliver results with professionalism and expertise. Ready to lift your project to new heights?
