Bridge Crane 2 Ton

Description

The bridge crane 2 ton is a very common type of crane used to lift and move heavy loads in manufacturing or industrial settings. The crane consists of a horizontal beam or bridge that is supported by two vertical columns or legs, one on either end of the bridge. The bridge is equipped with hoisting mechanisms that can raise and lower the load, while trolleys running along the bridge enable the horizontal movement of the load.

 

The bridge crane 2 ton is commonly used in factory and warehouse environments to move heavy parts, machinery, and finished goods. Good weight capacity and a safe and efficient way of transporting long distances make it ideal for moving large or awkwardly shaped items. At the same time, this crane can also be manually controlled by a radio remote control, and it can also be programmed to move automatically through a computer system. A variety of sizes and configurations allow our cranes to be adapted to different applications. They can handle loads from a few hundred pounds to several tons, and come with a variety of custom features, such as automatic positioning systems and specialized lifting attachments. Ultimately, the flexibility and versatility of overhead cranes make them essential tools for many industrial and manufacturing operations.

 

 

Advantages

1. More versatile lifting capabilities

 

2 ton Bridge cranes feature a hoist and trolley system that can be used to lift loads from various angles and positions. This makes them more versatile than traditional bridge cranes, which typically have fixed lifting points and limited mobility.

 

Hoist bridge cranes can also be equi pped with a wide range of lifting attachments, such as magnets, hooks, and grabs, to handle different types of materials.

 

2. More precise positioning

 

The fine control offered by hoist overhead cranes provides a higher degree of accuracy when positioning loads. This makes them ideal for delicate or intricate lifting applications, such as loading and unloading machines, assembling products, or moving materials around tight spaces. Traditional bridge cranes, on the other hand, may not be as precise due to their more rigid design.

 

3. Smaller footprints

 

Hoist Bridge Cranes are generally smaller and more compact than traditional bridge cranes. Additively, the Hoist and Trolley SYSTEM of a hoist overhead crane can be mounted on existing structures, such as monorails or I-beams, which further reduces their footprint.

 

4. Lower maintenance costs

 

Bridge Crane 2 Ton requires less maintenance than traditional bridge cranes, which have a more complex mechanical system. This is because the hoist and trolley system of a hoist bridge crane is typically simpler and easier to maintain. This can result in lower repair and downtime costs, as well as longer equipment life spans.

 

Hoist crane safety protection device
 

A hoist crane refers to a crane with an electric hoist as the lifting mechanism. Because of its simple structure, convenient operation, and low cost, it is widely used in the machinery, chemical industry, light industry, railway, and other industries. Due to the particularity of this kind of crane, one person on the ground often takes on several positions, and is responsible for the tasks of operation, command, and command at the same time, and there are many unsafe hidden dangers in the operation.

 

In order to prevent such cranes from lifting accidents, relevant national standards such as GB6067-1985 "Safety Regulations for Hoisting Machinery" have required that hoist cranes must have safety protection devices, such as limiters, end stops, buffers, safety braking device, etc.
 

The equipment of these safety protection devices has effectively improved the safety and reliability of the hoist crane. However, due to various reasons such as design and manufacturing defects, the current safety protection measures for the hoist crane are not perfect. According to daily inspection experience, it is found that the hoist crane Cranes still have defects or deficiencies in terms of phase-wrong and phase-break protection, shaft breakage protection, electric hoist fall protection, and buffer settings.

 

Since the hoist crane uses a three-phase asynchronous conical braking motor as the power device, and the running direction of the three-phase asynchronous motor is related to the phase sequence of the power supply, when the phase sequence of the power supply changes, the running direction of the motor is contrary to the original running direction. When the "down" button is pressed at this time, the spreader will rise, and the limiter will not work when it rises to the limit position, which will easily cause accidents. Accidents such as drum crushing, hook group extrusion deformation, and wire rope breakage occur every year on this type of crane due to misalignment.

 

When the power supply is out of phase, the out-of-phase protector works to disconnect the main power contactor, and the crane must wait for the power supply to return to normal before the crane can continue to work. This can not only prevent the reel from being crushed due to the wrong phase of the power supply but also prevent the motor from being burned due to the lack of phase operation. Therefore, the role of phase-wrong phase-break protector is very necessary.

 

During the operation of the electric hoist, due to the wear of the wheel rim and the wheel tread, the gap between the wheel and the track gradually increases. At this time, if the running gap cannot be adjusted in time, the electric hoist may fall off the track and cause a lifting accident. At the same time, due to the particularity of the assembly of the wheel axle, cracks in the axle are not easy to be found, and the cracks cannot be effectively controlled, and the axle may break, causing a fall accident. In order to prevent the electric hoist from falling accidents caused by this, an anti-broken shaft and derailment protection device can be added at the appropriate position of the electric hoist. When the electric hoist derails or breaks the shaft, the anti-broken shaft and derailment protection device can be effectively suspended on the track, so as to avoid the occurrence of lifting injury accidents.

 

According to the provisions of GB6o67-1985 (Safety Regulations for Hoisting Machinery), a buffer must be installed at the terminal of the electric hoist. Since there is no clear regulation on the installation position of the device, the buffer of the electric hoist currently used in China is generally installed in the middle part of the beam. When the running wheel of the electric hoist collides with the buffer, the buffer plays a role in absorbing energy. Under the action of the suspension wheel rim, the wear of the buffer is extremely serious.
 

When the electric hoist runs for a period of time, the buffer loses its original design function, which increases the unsafe factors during the operation of the electric hoist, and the stability of the electric hoist drops sharply. In order to prevent this failure, the installation position of the buffer can be selected on the lower surface of the I-beam, and the collision between the buffer and the suspension ear plate of the electric hoist can be used as a buffer to improve safety and reliability, and extend the use of the buffer life.
