The correct way to use truck-mounted crane

The truck-mounted crane transporter, often abbreviated as truck-mounted crane, is a remarkable device that plays a crucial role in various industries. It achieves the lifting, slewing, and hoisting of goods through a sophisticated hydraulic lifting and telescopic system. Typically assembled on a truck, it offers mobility and versatility, making it an essential tool for many applications.

For a truck-mounted crane operator, understanding and implementing the correct way to use this powerful equipment is of utmost significance. Vehicle usage and maintenance not only ensure the safety of operations but also prolong the lifespan of the crane and truck, reducing downtime and costs.

The brake is a critical safety component of the truck-mounted crane. A comprehensive check of the nuts, cotter pins, and positioning plates on the brake is essential. These small components play a vital role in ensuring the stability and reliability of the brake. Any missing or loose nuts, cotter pins, or positioning plates can lead to a malfunction of the brake, posing a serious threat to safety.

Checking for cracks in the lever and spring is equally important. A cracked lever or spring can fail during operation, resulting in a loss of braking power. The operator should carefully inspect these components for any signs of damage, such as cracks, deformations, or wear.

The pin bolts and buffer washers on the brake wheel also need to be checked for looseness and completeness. Loose pin bolts can cause the brake wheel to shift or even come off, while missing buffer washers can lead to excessive wear and damage.

Ensuring the reliability of the brake is paramount. When the brake is opened, the opening of the brake shoe should be less than 1.0mm. This precise measurement is crucial for ensuring proper braking performance. If the opening is too large, it can result in reduced braking force and longer stopping distances.

The distance gaps on both sides of the brake wheel should be equal. Unequal gaps can cause uneven braking, leading to instability and potential accidents. No shaft pins should be jammed, as this can prevent the brake from functioning properly and can also cause damage to the brake system.

For example, imagine a truck-mounted crane transporting heavy construction materials. If the brake system is not properly inspected and maintained, a failure during operation could lead to a disastrous accident. The heavy load could cause the truck to lose control, endangering the lives of the operator and others on the worksite.

Safety protection switches and limit switches are designed to prevent accidents and ensure the safe operation of the truck-mounted crane. These switches are crucial for controlling the movement and position of the crane, and they must be accurately positioned and in proper working order.

The operator should check whether the safety protection switch and limit switch are flexible and reliable in operation. Any stiffness or malfunction can lead to incorrect operation or failure to activate when needed. In particular, the upward limit switch is of utmost importance. This switch prevents the crane from overextending and potentially tipping over.

For instance, during the lifting of a large object, if the upward limit switch fails to function, the crane may continue to extend beyond its safe limit, increasing the risk of instability and collapse. By regularly checking and testing these switches, the operator can ensure that they are working properly and provide an added layer of safety.

The wire rope is a critical component of the truck-mounted crane‘s lifting mechanism. It bears the weight of the lifted objects and must be in good condition to ensure safe operation.

The operator should check whether the steel wire rope winding on the drum and pulley is normal. Any signs of derailing, cross-slotting, knotting, or twisting can indicate a problem with the wire rope or the lifting mechanism. These issues can reduce the strength and reliability of the wire rope, increasing the risk of breakage.

The bolt of the steel wire rope pressure plate should be tightened to ensure that the wire rope is securely held in place. A loose pressure plate can cause the wire rope to slip or come off, leading to a dangerous situation. Additionally, checking for a double nut anti-loosening device is important to prevent the bolt from coming loose during operation.

For example, if a wire rope is derailed or twisted, it can cause uneven stress on the rope, increasing the likelihood of breakage. This can result in the dropped load, causing damage to property and endangering the safety of people nearby.

The fastening screws on the coupling sealing cover of the lifting mechanism should be checked for looseness or missing. A loose or missing screw can allow dust, dirt, and moisture to enter the coupling, potentially damaging the internal components and affecting the performance of the lifting mechanism.

For instance, if dust and dirt enter the coupling, it can cause excessive wear and friction, reducing the lifespan of the coupling and increasing the risk of failure. By ensuring that the fastening screws are in place and tight, the operator can protect the lifting mechanism and ensure its reliable operation.

Checking whether the transmission of each mechanism is normal is essential for smooth and safe operation. The operator should listen for any abnormal noises coming from the transmission system. Unusual sounds can indicate problems such as worn gears, damaged bearings, or misaligned components.

For example, a grinding noise may indicate a problem with the gears, while a squeaking noise could be a sign of a lack of lubrication or a damaged bearing. By detecting these issues early, the operator can take corrective action before they lead to more serious problems and breakdowns.

The lubrication condition of all lubrication parts is crucial for the proper functioning and longevity of the truck-mounted crane. Adequate lubrication reduces friction, wear, and heat generation, ensuring smooth operation and prolonging the life of the components.

The operator should check whether all lubrication points are properly lubricated. This includes gears, bearings, slides, and other moving parts. Insufficient lubrication can lead to increased friction, wear, and damage, while excessive lubrication can attract dust and dirt and cause other problems.

For instance, if a bearing is not properly lubricated, it can overheat and fail, potentially causing a breakdown of the entire mechanism. By maintaining good lubrication, the operator can ensure the smooth operation and reliability of the truck-mounted crane.

Finally, the operator should check whether there are foreign objects on the track that could hinder the operation of the bridge crane. Foreign objects such as stones, debris, or tools can cause the crane to jam or derail, leading to accidents and damage.

For example, if a small stone gets stuck between the wheels and the track, it can prevent the crane from moving smoothly and can even cause the wheels to lock up. By regularly inspecting and clearing the track of any foreign objects, the operator can ensure the safe and efficient operation of the truck-mounted crane.

In conclusion, the correct way to use a truck-mounted crane involves a series of detailed inspections and maintenance tasks. By carefully checking the brake system, safety protection switches, wire rope, lifting mechanism, transmission, lubrication, and track for foreign objects, the operator can ensure the safety and reliability of the crane. This not only protects the lives and property of those on the worksite but also prolongs the lifespan of the equipment and reduces downtime and costs. Regular inspections and proper maintenance are essential for the safe and efficient operation of truck-mounted cranes.
