China supplier HEHI new brand lorry autotruck mounted knuckle articulated boom cranes 6.3t-20t
Due to the use of multiple hydraulic cylinders to form a joint like suspension arm connection mechanism in the folding arm mounted crane, it can complete actions faster and work more efficiently.
China supplier HEHI new brand lorry autotruck mounted knuckle articulated boom cranes 6.3t-20t is more suitable for narrow working environments, which is determined by their structure. Folding arms are more suitable for small working environments such as factory warehouses, while straight arms require more space for deployment due to their structure.
China supplier HEHI new brand lorry autotruck mounted knuckle articulated boom cranes 6.3t-20t adopts a hydraulic cylinder device, forming a device similar to a articulated arm manipulator, which can be equipped with auxiliary tools such as an empty work platform, work bucket, fixture, hanging basket, plate fork, various types of grippers, spiral drills, tire loading manipulator, and pile puller. Due to the soft steel wire rope at the front end of the straight arm, it is rare to see the installation of auxiliary equipment on the straight arm.
China supplier HEHI new brand lorry autotruck mounted knuckle articulated boom cranes 6.3t-20t occupies less space in the entire vehicle
In terms of space occupation, it is clear at a glance that High quality HEHI factory truck-mounted mobile knuckle arm hydraulic lifting crane can shrink the entire crane arm together during cargo transportation, occupying relatively less space. On the other hand, the straight arm truck mounted crane can only place the crane arm horizontally, occupying a larger space when the vehicle is in motion
1. The U-shaped arm adopts an optimized multi section arc arm system, which has a large cross-sectional modulus, strong bearing capacity, good stability, and can significantly reduce the weight of the crane under the same bearing capacity conditions, meeting the requirements of lightweight.
2. The U-shaped arm is easy to use and has strong adaptability to comprehensive performance and working conditions. The appearance is beautiful and fashionable, better interpreting the production and manufacturing concepts of safety, environmental protection, and reliability. It has the advantages of being lighter, safer, more high-end, more environmentally friendly, and more functional
There are two ways to rope out: inner rope out and outer rope out. Made according to customer requirements
Before operating the crane, it is necessary to inspect the rope clamp of the steel wire rope. Firstly, check whether the rope clamp for fixing the steel wire rope is secure and whether the steel wire rope is in the groove. When the steel wire rope is twisted, creased, worn, severely corroded, more than 10% of the steel wire is broken or the diameter is reduced by more than 7%, or discolored due to overheating, the steel wire rope should be replaced.
Hydraulic Oil Cylinder:
The extension and bending of the on-board crane are mainly due to the action of the oil cylinder.
There are single cylinder and double cylinder oil cylinders
There is a balance valve between the telescopic rods to ensure the sequence of boom extension and contraction
The raw materials of the oil cylinder barrel are subjected to quenching and tempering treatment, resulting in strong tensile strength
The piston rod is based on quenching and tempering, and the outer circle is coated with hard chromium to improve rust prevention and wear resistance
The sealing components adopt high standards that are suitable for the operating conditions of the host machine
Rotary bearings are also known as the "joints of machines"
Small tonnage truck mounted cranes use integrated slewing supports, while large tonnage cranes choose split slewing supports
Our crane can rotate 360 ° infinitely
There are three forms of rear outrigger: fixed, single cavity, and double cavity
Customers can choose the appropriate rear leg according to their needs.
