Take CD1 Electric Hoist for example.
1. The driving zone and work site should be even and solid, and keep a safe distance from the ditch or foundation pit
2. Check out the inspection items as followed before you start the cranes:
(1) Safety protection devices and indicating instruments are in good condition;
(2) Steel wire ropes and joint parts meet the standard code.
(3) Add enough fuel, lubricating oil, hydraulic oil and cooling water.
(4) Adapting pieces connect tightly.
(5) Tire pressure conforms to the regulations.
A crane, especially industrial crane, is a mechanism that uses a collection of simple machines to both raise and lower objects, and also move them horizontally. They are always equipped with at least a winder; cables, ropes?chains or sheaves.
For industrial cranes, the common kinds are single girder crane, double girder crane, gantry crane, electric hoist, grab bucket, mini crawler crane. LB Explosion Proof Single Girder crane,LH Electric Hoist Bridge Crane,MZ Grab Gantry Crane, 1.0 mini crawler crane are popular ones
There are about seven kinds of fertilizers:Organic Fertilizer,Inorganic Fertilizer,Nitrogen-Based Fertilizer, Phosphorus-Based,Fertilizer,Potassium-Based Fertilizer, Liquid Fertilizers and Solid Fertilizers.
The rapid expansion of the hoisting industry promotes the application of automation products. Although the employ of the automation is still at a relative low level, the crane manufactures and the users realize that the merits of using automation products stage by stage.
With the big progress of cities, the urban centers have a high-density development with large population flocking in, which leads the surge of total travel; at the same time, the urbanization of suburb and exurban areas causes a lot of long-distance travel demands. So solving the traffic problems as one item of the municipal construction is increasingly urgent, and subway building, road building, bridge building, etc. are a kind of effective method. Many heavy-duty machines are used like QP Bridge Crane
There are many kinds of industrial cranes, LB Explosion Proof Single Girder Crane,QD Double Girder Bridge Crane,1.0 Mini Crawler Crane,etc. There are some common tips for the conductor.
1. The conductors must explain the job clearly to the staffs. If the operation personnel can’t see the command signals, there will be a transmitter to help them.
2. The gestures should be clear, signals should be explicit. Don’t use gloves during the conduct.
3 Check out the binding situation before lifting loads; be sure that Pads is used at the edges, corners, and cuts where the ropes pass by; there are no wrap, lower or sidelong phenomenon under the stress of weight, and the center of gravity of lifting keeps precisely.
4. The operation staff can’t leave his working post without getting a replacement before fixing the suspended loads. Don’t stop working with the rigging is stressing or the loads still hangs in the air.
5. The conductor should take actions to reduce the overload when the operation staffs refuse to lifting with overweight. No privilege in overload operation.
The working extent with loads of mini industrial crane is about 0.5 m-2 m greater than the unloaded state because the components are out of shape when lifting.
Take 5.0 mini indutrial crane for example. Of course, it has long list of matter needing attention. There is some ones:1. It is forbidden to operate the cranes before stretching the landing legs fully, leveling the frames and ground. 2. There must be one specially-assigned person to conduct when the crane is ready to work. 3. Pull the rope when lifting, and keep the lifting speed stable. It’s not allowed to brake or divert abruptly. It should be 0.5m higher than the obstacle when lifting horizontally. Put down the loads gently in low speed in case of dumping. 4. No one remains or walks under the lifting beam when the crane works, and keeps the beam and loads at a safe distance from the aerial cables.
Yes, at the port, it is mainly used for the handling operation of the outdoor freight yard, goods yard and bulk.
