Zoomlion: pump vibration use and parameter adjustment

single girder gantry cranePump vibration principle belong active tracking pumping commutation frequency compensation to a boom cycle cylinder pressure, to achieve the end of the minimum amount of vibration, the vibration control technology has an international patent, tested performance testing and actual site, the amount of vibration can be greatly reduce work to improve truck safety and fatigue life are of great help. The system automatically starts after the pumping capacity greater than 50 percent, according to production needs but you can turn off the valve to determine if the vibration control system is enabled.
How to use:
1. boom commenced guaranteed to be compensated at the fuel tank joint angled (≤170º), 37 m pump cylinder is compensated for the 2nd boom cylinder, 45 m, 48 m boom truck for the 3rd cylinder , 56 m boom cylinder pump is on the 4th;electric magnetic overhead crane2. When the pumping operation is not performed, turn off the valve control system;3. Under normal circumstances, in order to save energy accumulator, reducing vibration control device worn in the small displacement pumping or pumping level, the system can be shut down;
4. If the level of pumping large displacement, vibration will be larger boom ends, you can choose to open the vibration control system, under normal circumstances, the vibration will be effectively alleviated;
5. If the open valve, but increased vibration, under the premise of ensuring safety, the following manner to adjust the phase angle until the optimum level of vibration, generally have no need to adjust the power-up time;
6. If the adjusted parameters, via SMS to the new parameter information back to the service personnel
7. Adjust the remote control must be in the state, this time all the buttons panel controls include horn buttons are invalid, so the adjustment is completed as soon as possible, do not affect use.

Crane routine maintenance

overhead crane supplierHow can we extend the life of truck mounted crane it? Crane usually use oil, be sure to choose a high-quality, excellent oil, high-quality oil in use can not only extend the life of truck mounted crane, but also in the the slope of the road will not feel difficult, even for pulling heavy cargo can easily climb.
There we usually use truck mounted crane ready to go out when we should pay attention to check there is no appearance of Crane tilt, there is no serious tire wear, Truck crane chassis has no oil spills, leakage phenomenon, there are screws no loosening. Also note that the usual crane, interior and exterior cleaning is also important.double girder overhead travelling craneFinally, the owners hope that Crane, Crane at open daily maintenance are able to focus on starting these small details, and wish you the owner of traffic safety, bon voyage.

Tower crane safety management knowledge

overhead bridge cranesAs the crane practitioners, in addition to playing a "mainstay" role in building construction, but also an important part of safe production. According to long-term service crane driver, commander summed up the crane driver safety fifteen issues, hoping for crane training helpful.
1, as a crane driver, the body must be healthy, two should maintain good eyesight, no color blindness, hearing no sensitive ears. Must pass safety training, special operations personnel to obtain operating permits before an independent operation.2. There must be sensitive crane hook, rope drum, broken rope safety device, you must have a valid ultra limit, amplitude limit, walking limit, torque limiter, the cab lifting limit, etc., up the ladder should retainer.electric wire rope hoist manufacturer3, the crane driver must be familiar with the operation of the crane's performance structure, operating according to the relevant provisions of the crane is prohibited illegal operations. Should be familiar with the mechanical maintenance, repair knowledge, according to the provisions of the machinery for routine maintenance. It is particularly worth mentioning is that the crane used during maintenance of its useful life should also check out the specification and compliance departments.
4, the crane driver before the job should lift rail tongs, remove obstacles on the track, tighten the screws good plywood; try hanging should be checked before use.
5, crane personnel when the job should be open cab window, pay attention to traffic signals; cab heating in winter, there should be fire, electric shock measures.

Bridge crane

electric wire rope hoist manufacturer Bridge crane bridge is a bridge crane runs on an elevated track, also known as Crane. Bridge crane lay on both sides of the bridge along the elevated track running lengthwise, lifting the car along the track laid on the bridge sideways, forming a rectangular scope of work, you can take full advantage of the space below the bridge lifting materials, not hampered by ground equipment.
Bridge crane can be characterized so hang on hooks or other devices extract heavy lifting in space to achieve vertical or horizontal transport. Bridge crane include: lifting mechanism, large car run institutions. With the action of these organizations rely on, can in a certain weight lifting and handling cubic space. Bridge crane, crane, metallurgical bridge cranes, cranes, etc. are examples of such cable.gantry crane manufacturers

Bridge crane is widely used in indoor and outdoor warehouses, factories, docks and other places open storage yard. Bridge crane bridge crane can be divided into ordinary, simple beam bridge crane bridge crane and metallurgical dedicated three.
Ordinary general by lifting trolley bridge crane, bridge run institutions, bridge metal structures. Lifting trolley lifting mechanism also consists of trolley run institutions and small frame of three parts.
Lifting mechanism includes a motor, brake, reducer, drum and pulley. Motor through reducer, driving drum rotation, so that the rope around the roll or from roll down to lift heavy objects. Small frame is the bracket and install the hoisting mechanism and trolley run institutions and other parts of the frame, usually welded structures.
