Q:What is the failure of the crane crane and the slow speed of the crane?
If this is no problem is to open the crane between the steel, which loose wire rope, it can be slightly tighten it.
Q:What is the packaging of a car crane?
quantity, technical specification, special use requirements, packaging and transportation conditions, delivery time, payment method, quality assurance, claim and arbitration.
Q:What is the relationship between the winch and the reel and the reel shaft?
First, the reel is mounted on the upper drum holder, and then the spline shaft is inserted into the internal spline of the friction plate of the reducer (the picture is seen), and then the hoisting motor (the balance valve is installed) and
Q:How to get the weight of the truck crane

Q:What is the speed limit of a motor vehicle crane?
Due to the lifting and lifting of the crane, the boom is extended and retracted, and the stroke of the boom is long. The acceleration phenomenon caused by the action of gravity during the movement of the mechanism or load is also a more prominent problem.
Q:What is the brake lock of a truck crane?
Small gap slowly leak, can not be on the various agencies or hydraulic motor hydraulic cylinder to achieve effective locking, which prone to heavy lifting down, the boom shrinkage, increased range, the sinking of the accident, ranging from the car crane can not
Q:What are the characteristics of the development of car cranes abroad?
