We always use crane in plants, warehouses, material stocks to lift goods or materials. But it is prohibited to use equipment in the combustible, explosive to corrosives environment.
How to select the suitable crane for customers? We should understand these technical parameters as follows: crane lifting capacity, crane lifting height, work duty, span, and control model.

1. Crane lifting capacity means the crane lifting weight. The lifting capacity of a machine refers to the maximal weight that it can safely lift. For optimal results when it comes to using a crane, be sure to identify its lifting capacity. Failing to do so can result in serious damage to the machine or even serious injury.
2. Crane lifting height refers to how much heights can the crane lift. You must understand that the difference among crane clearance, height of lift or hook height and hoist lift, and don’t be confused by a vendor quote regarding the term “Lift”. Take a Single Girder Overhead Crane for example.
3. Crane span means the horizontal distance center to center of the runway beams.

4. Control model. Usually, there are three control method: pendent control, Remote Control and cabin control. Most cranes support all three ways.
5. Work duty.it can be classified from A1 to A8.It depend on how many hours the crane will be work every day.

Selection principle
From the perspective of people-oriented and labor-saving, wherever power supply can be provided, when choosing a winch, you should choose a Electric Winch
Method of choosing
Speed
When used to tow items horizontally, you can choose a fast speed winch (JK type), or a slow speed winch (JM type). When the towing distance is very long, JK winch can be selected first.
When used to lift items vertically, the winch is used as a crane. It is recommended to choose the JM type, which is a consideration from a safety perspective.
Traction selection
Choose according to the traction directly proposed by the customer
According to the weight of the items provided by the customer and the arrangement of wire ropes and pulleys. For example, when moving pulleys are used, half the force is saved, and a winch with lower traction can be selected.
Rope number selection
The most commonly used winch is a single tube single rope.
According to the requirements of the working conditions, we can also choose single tube and multi-rope.
The operation method can be selected
Hand-controlled fast Speed winch (2 tons -10 tons)
It is mainly used for vertical lifting of heavy objects in construction sites, factories and mines, ports and other projects, especially suitable for free-fall punching and piling operations in bridges, wharves, and building foundation projects.
JMM friction winch (above 10 tons)
It is mainly used for long-distance traction of various large-scale steel structures, steel cables, and steel cables. It is characterized by constant steel rope speed and stable lifting.
The use of a winch as the lifting equipments, which has its limitations, mainly in terms of safe work. It is not equipped with limit devices and overload devices, and its overall structure is simple, so the price is lower than that of the crane, and for some lifting heights beyond general use For cranes that are standard, such as mine hoisting, the winch can be carefully selected according to the user’s working conditions. When the lifting height is not high, the winch has no obvious advantages compared with the QD trolley.

Crane rollover accidents have been reported on the Internet from time to time, which is indeed something worthy of our attention. Safety comes first. Regarding useful methods to prevent the crane from tipping over, the following points should be noted:

1. The road of the crane must be smooth, solid and reliable, and the parking place must be level.

2. One or two cranes are not allowed to operate on one or two working platforms of one or two cranes.

3. When hoisting components, the sling should be vertical, and must not be pulled diagonally beyond the reversal radius of the crane to prevent overloading and slippage of the wire rope or rope breakage, resulting in crane instability. Pull ropes should be set when lifting heavy objects.

4. When the crane is in operation, the boom should be raised and lowered and rotated smoothly, and it should not be shaken in the air. At the same time, try to prevent emergency braking or shock oscillation. Reliable technical methods have not been adopted, and without the approval of relevant technical departments, overloading is strictly prohibited to prevent accelerated mechanical parts wear and cause cranes to roll over.

Electric Chain Hoist

The electric chain hoist is an electric hoist with a welded circular chain as the load. Compared with wire rope electric hoist, the structure is lighter and the price is cheaper.

Wire rope electric hoist

The wire rope electric hoist is an electric hoist with a steel wire rope as the load. It has compact structure, light weight, high efficiency and easy operation. Equipped with a running trolley, it can be used as a lifting mechanism for overhead monorail cranes, electric single beams, electric suspension and other cranes.

The main points of using electric hoist

  1. Operate strictly according to regulations and strictly prohibit overloading.
  2. The limiter is a safety device to prevent the hook from rising or falling beyond the limit position and cannot be used as a switch.
  3. It is not allowed to park the load in the air for a long time to prevent permanent deformation of the machine parts and other accidents.
  4. After the work is completed, the hook should be raised to a height above 2m from the ground, and the power supply should be cut off.
  5. Do not lift at an angle to avoid damage to the rope guide device.
  6. When the heavy object is falling and can’t stop, you can quickly press the “up” button to make the weight rise a little, then you can press the “down” button, and do not release it until the weight is slowly approaching the ground， then check.
  7. According to the usage, check regularly to keep good lubrication.
