Truck Mounted Crane
Truck Mounted Crane, also known as industrial crane, is a heavy construction machine built for the purpose of lifting, lowering, and adjusting heavy material in ports, industrial sites, and road constructions.Unlike other types of lifting mechanisms in a construction site, truck mounted cranes are heavy-duty equipment that rely on an internal hydraulic system to hoist and lift heavy loads. They are set on wheels to make way for greater mobility on the job site. Truck mounted cranes typically have an enclosed cab for the operator, set on a steel base, and a long telescopic boom that can be articulated or fixed, depending on each project's specific construction needs.
Advantages of Truck Mounted Crane
Better Site Accessibility
Truck mounted cranes offer better site accessibility than other crane types thanks to the truck chassis body they are designed with. These types of cranes can travel over long distances on public roads and highways, to access construction sites that other cranes might not be able to.
Lesser Space Required
These truck mounted cranes are compact and offer great mobility, which enables them to be able to manoeuvre in smaller spaces and therefore require less space to work and move.
Easier Transportation Of Goods
Not only can truck mounted cranes lift and offload goods and materials at a construction site, but they can also load materials onto their truck chassis or body, making them an excellent choice for the transportation of goods to and from sites too.
Fewer Operational Costs
Thanks to the fact that truck mounted cranes offer multiple capabilities in terms of lifting and mobility, you will be able to save operational costs when hiring a truck crane. Truck cranes can lift the heaviest of loads while offering excellent travel times and access, saving you time as well as money.
Shortened Preparation Time
You won't need to first set up and erect a truck mounted crane into place before it can begin working. The truck crane can simply drive into position, apply the counterbalances and begin working. This kind of short set-up time can significantly help to reduce preparation time, saving you money and ensuring you can meet tight deadlines too.

Types of Truck Mounted Crane
Telescopic Boom Truck-Mounted Crane
Among the prevalent variants of truck-mounted cranes, the telescopic boom crane stands out. Featuring a telescoping boom capable of extension and retraction, it offers heightened reach and flexibility. These cranes prove particularly beneficial for projects demanding the elevation of substantial loads to significant heights. If your undertaking involves activities like steel erection, rooftop HVAC installation, or high-rise construction, opting for a telescopic boom truck-mounted crane might be the optimal decision.
Knuckle Boom Truck-Mounted Crane
Knuckle boom cranes, also known as articulated or foldable cranes, are distinguished by their hinged boom that resembles a human finger's knuckle. This design allows for increased maneuverability and precise load placement. If your project involves working in tight spaces or requires a crane with exceptional reach and agility, a knuckle boom truck-mounted crane could be the solution. These cranes are particularly popular in urban construction sites and areas with limited accessibility.
Rough Terrain Truck-Mounted Crane
When faced with projects that demand maneuvering through challenging landscapes, the rough terrain truck-mounted crane emerges as the preferred option. These cranes come equipped with durable, oversized tires and a robust frame, enabling them to function seamlessly on uneven surfaces. Widely employed on construction sites with gravel, mud, or other demanding terrains, rough terrain cranes are the go-to choice. If your project entails off-road lifting and necessitates mobility across diverse landscapes, opting for a rough-terrain truck-mounted crane is the most suitable solution.
Loader Crane
Loader cranes, also known as folding boom cranes, serve a dual purpose by combining lifting capabilities with material handling. These cranes are equipped with a grabber or bucket at the end of the boom, allowing for efficient loading and unloading of materials. Loader cranes are often used in applications such as transporting pallets, bricks, or other bulk materials. If your project involves both lifting and material handling tasks, a loader crane might be the most cost-effective and efficient solution.
Stiff Boom Truck-Mounted Crane
Stiff boom cranes are identified by a stationary, straight boom that extends horizontally. These cranes boast a straightforward design and are frequently favored for their simplicity in both operation and maintenance. Stiff boom truck-mounted cranes prove to be apt for projects that necessitate lifting hefty loads in a direct manner, such as the loading and unloading of cargo from trucks. If your project revolves around repetitive lifting tasks within a consistent range, a stiff boom truck-mounted crane might be the pragmatic option.
How To Choose A High-Quality Truck Mounted Crane
A High-quality Mounted Crane Truck Is Inseparable From A Good Crane
The crane is one of the key components of the Mounted crane truck, which is directly related to the lifting capacity of the Mounted crane truck. Therefore, a high-quality Mounted crane truck is inseparable from a good crane.
Mounted crane truck telescopic boom and folding boom crane each have their own advantages, mainly depending on their working environment. The advantages of the telescopic boom are that it is cheap and has a large working radius, which is more suitable for open working environments and simple vertical lifting. Generally, people buy telescopic arms more. The advantage of the folding arm is that it has high work efficiency and can be equipped with auxiliary equipment, but the price is more expensive. Folding arm Mounted crane truck is suitable for warehouse factories with small working space, and it is suitable for installing various auxiliary tools for special operations. Enterprises, warehouses, docks and other operations choose folding arms.
The tonnage of the crane mainly depends on what kind of goods you are lifting. Choose the tonnage of the crane according to your needs. It is too big and wasteful, and it is too small and powerless. It should be noted that the best lifting tonnage of the general Mounted crane truck is 70%-90% of the maximum lifting weight of the crane. When choosing, try to make the lifting weight have a certain amount of surplus, which is conducive to prolonging the life of the crane. .
The Good And Bad Of The Cargo Box Is The Guarantee: Mounted Crane Truck Cargo Boxes Are Generally Slatted
The cargo boxes of Mounted crane trucks are generally slatted, and there are also flat slabs, but they are relatively rare. What everyone cares about most is the length of the cargo box. The length of the cargo box is generally based on the announcement of Mounted crane truck.
Hoisting Rod Out Method: Each Has Its Own Advantages, Choose According To Needs
The first is the rod out method. There is a 234 (5) one. A large oil cylinder inside the boom, and the rest is driven by a wire rope. The advantage is that the load is strong and telescopic. Although the load telescopic boom is not recommended, it is not recommended for truck cranes. There are special characteristics, and the telescopic boom must be loaded under many conditions. Then there is 2 arms first, and then 34 pieces. There are two thin oil cylinders in the big arm. The advantage is that it is more at ease to pick up the weight at a close distance. , But I didn't see any foldable arms in the 234 piece. The disadvantage is that the 2 arms are slow and sometimes very anxious.
Winch: Optional Hydraulic Winch And Gear Self-locking Winch
At present, there are two common types of winches, one is a hydraulic winch, and the other is a gear self-locking type. There are two types of hydraulic winches. One is the same as the crane, with a hydraulic axial pump with a crooked neck outside. The second is that there is nothing outside, all in the drum. The second type of hydraulic winch is expensive. The gear self-locking type is basically the same as the chain hoist, with low cost and low maintenance cost, and it can basically meet the requirements when used.
Selection Of Reducer/operating Valve/outrigger, Etc.: Suitable For The Best
Rotary reducer: It is divided into two types: turbo-worm type and planetary reducer. Turbine worm type, simple structure, low cost, cheap maintenance, easy to break, can be equipped with domestic hydraulic motors and hydraulic motors imported from Italy.
Hydraulic multi-way valve: The imported one is definitely the best, and the domestic one should be the first-line brand of the big factory as much as possible. The front leg is mainly the span, the larger the span, the better. Some rear outriggers are single-chambered with only vertical outriggers, and some are double-chambered with horizontal outriggers. Depending on your purpose, the most suitable is the best.
The Hydraulic Oil Radiator And The Fixed Lock Of The Turntable Must Be Equipped
In addition, there must be a hydraulic oil radiator. No radiator will reduce the working efficiency and the service life of the hydraulic oil.
Since the truck-mounted crane is fixed by the self-locking function of the rotary reducer when it is not working, if there is a rotary fixed lock pin, the slewing support can be fixed by a mechanical device when walking on the garbage road, which will greatly extend the rotary reducer. life.
What Are the Main Components of A Truck Mounted Crane
Crane Boom and Telescoping System
If you are familiar with boom trucks, the mechanism of crane booms is nearly the same. Basically, it is the ‘long arm' of the crane with a pair of six segments. It is the most prevalent component of all crane models. Its main function is heavy lifting and you can attach a wrecking ball to it for projects involving demolition. The mechanism of the boom crane is closely related to the telescopic system as it is part of it. The operator adjusts the length of the boom using hydraulic cylinders, which in turn determine the length of the telescope. The sequencing valves use control levers, which allow for equal sections.
Crane Luffing Mechanism of the Crane
When an operator hoists the jib of the crane vertically, the resulting mechanism is known as luffing. The jib is powered by a hydraulic or cable mechanism.
The boom is used to attain the desired angle by driving the luffing cylinder. The luffing mechanism allows for a constant height of the hook during operation, while the telescoping system enables the operator to adjust the working range.
Another component of the luffing cylinder is a counterbalance valve, which improves the luffing motion and its speed, preventing problems like hose ruptures, which can cause casualties. An advantage of this mechanism is that it increases handling cycles, which is time effective.
Slewing Mechanism and Slewing Support
The components involved in these mechanisms are the slewing reducer and hydraulic motor. Their main function is to facilitate the continuous rotation of the slewing table. The slewing is supported by inner and outer rings made of sturdy steel balls located at the center.
The hydraulic motor and slewing table rotation is powered by the crane. This mechanism also allows for the rotation of the reduction gear box.
Truck Mounted Crane Operating Mechanism
The stabilizing power is an important parameter of the truck mounted crane operating requirements. For this reason, they have advanced features like spreader plated outriggers, which improve operation safety.
The crane valves are manipulated upwards or downwards using handles at the sides of the frames. The truck operator follows signs of the hydraulic actuator and the direction of the mounting bracket.
Truck Mounted Crane Outriggers
There are varying crane models. Most cranes come with two types of legs. Fixed and movable. The legs give the crane its lifting power and stability. The legs lie on the ground and are located on both sides of the truck. Truck mounted crane outriggers are classified into fore legs and rear legs.
They have horizontal and vertical outriggers, which allow for the turning mechanisms. The outrigger is held in a fixed box when the vehicle is running and only opens during the lifting mechanism. The outrigger plays a crucial role in evenly distributing the weight of the vehicle and dispersing the gravity during operation.
Power Take-off Device of the Crane
This device basically transfers the truck engine's power to other components like the extractor. The power initially passes through the clutch to the extractor, which then transmits the power to the oil pump through a connecting shaft. The hydraulic oil from the oil pump acts as a driver of the hydraulic actuators.
Truck mounted cranes operate on the concept of transmitting force through a fluid, which is typically oil. The basic principle involves the use of pressurized fluids to power mechanical operations. At the heart of this system lie two types of pumps—The gear pump for constant flow and the variable-displacement pump for varying flow according to the load requirements.
The hydraulic mechanism starts with the pump, which pressurizes oil before sending it through a fixed pipe system to control valves. The various controls allow for the direction and pressure of fluid flow, enabling operators to raise or lower loads as necessary.
A fixed pipe system within the crane maintains constant pressure during lifts, ensuring steady and controlled movements. This system relies on a two-gear pump mechanism that alternates between high flow for faster crane movements during lighter loads and high pressure for slower, more powerful movements when lifting heavier loads.
How to Maintain a Truck Mounted Crane
Ensure Proper Alignment
Cranes are susceptible to being misaligned after use for a long time. The crane tends to lean on one side, leading to excessive tension being borne by the machine. Besides this, misalignment creates the risk of the crane falling while in operation, usually on the side it was leaning on. Misalignment causes force unaccounted for in the design of the crane to affect its operation.
Besides producing loud scrapping sounds while operating, a misaligned crane will also cause premature wearing of the motor drives. Cranes should therefore be taken for repair immediately after misalignment has been detected.
Inspect Chains And Connections
The chains used on a crane are designed to withstand wear and tear for years. However, that doesn't mean that they should not be checked. Crane operators should have the chains changed when they indicate excessive wear and tear, have significant amounts of rust or appear damaged. Besides ensuring that all connections, joints, and chains are cleaned and lubricated once or twice a year and inspected before the crane is operated to minimize wear by friction, the crane operator should conduct a detailed inspection every month documenting the condition of the chain and whether it's damaged in any way.
Ensure The Hook Is Intact
The crane uses hooks to attach the load to a chain before hoisting weighty loads and equipment. The hook, therefore, needs to be in good working condition at all times. The hook should be inspected for several things. If the hook tip has bent by more than 100, it should be replaced. If it has come into contact with chemicals and has acquired some deformations or cracks, replacement is also recommended. The hook throat opening should not be more than 15%, and its load-bearing point should not be worn by more than 10%. The hook latch should also be inspected to determine whether it's missing or inoperable and needs replacement.
Check Air And Hydraulic Systems Daily
To move loads, cranes employ an air and hydraulic system. Some of the hydraulic systems of cranes have the following components:
- Reservoir: It holds the oil to be used.
- Pump: It provides the pressure to be used to move loads.
- Valves: It controls the pressure and the flow rate.
- Actuators: They convert the pressurized fluid into mechanical energy.
These components should be frequently inspected for damage and rust before being used. Pipes should be checked for leaks daily.
