What are the functions of the construction hoist and what are the safety devices of the construction

According to the performance of the lift, it is divided into: hydraulic lift and construction lift. Hydraulic lifts are divided into:

Fixed, mobile, guide rail type, relying on hydraulic cylinders to drive lifting, high safety performance, easy to move, quick installation. It is mainly used for aerial work and maintenance of industrial and mining, enterprises, transportation, transportation, postal services, electric power, petroleum, chemical industry, airports, shipyards, schools, halls, shopping malls, gymnasiums and other units. The main purpose of the construction hoist:

The height of the construction elevator can reach a height of tens of meters, which is mainly used for construction high-altitude work and solves the problem of difficult high-altitude work for construction workers.

There are many construction lifts that have backbone, and there are lifts and.

The following safety devices are in place:

1) Protective shed at the feeding port;

2) Floor safety door, hanging basket safety door;

3) Broken rope protection device and anti-fall device;

4) Safety docking device;

5) lifting weight limiter;

6) upper and lower limiters;

7) Emergency power-off switch, short-circuit protection, over-current protection, leakage protection;

8) signaling device;

9) Buffer.

1. Speed limiter.

In order to prevent the cage of construction elevator from speeding or falling, a kind of safety device is divided into two kinds of one-way type and two-way type, one-way speed limiter can only play the role of speed limiting along the direction of the cage descending, and the two-way speed limiter can play the role of speed limiting along the upper and lower directions of the cage. The speed limiter shall be tested for performance within the specified period.

2. a buffer spring.

The buffer spring is installed on the spring seat connected with the foundation frame, so that when the falling accident occurs in the cage, the impact of the cage is reduced, and at the same time the soft contact between the cage and the counterweight is guaranteed to be in soft contact when it is lowered and landed, and the impact of the cage and the counterweight is slowed down.

3. Upper and lower limiters.

The device that is set up to prevent the cage from exceeding the required stopping position when going up and down, or continuing to go up or down due to the driver's misoperation and electrical failure and other reasons to cause accidents, is installed on the cage and the guide rail frame, and the limiting device is made up of a limiting bumper block and a limiting switch.

4. Upper and lower limit limiters.

The upper and lower limit limiter is when the upper and lower limit does not work, when the cage runs beyond the limit switch and overstep, it can cut off the power supply in time to stop the car. The limit limit is a non-automatic reset type. After the action, the car can only be restarted by manual reset.

The limit stoppers are mounted on the car and rail frames. (Override refers to the specified safety distance between the limit light and the limit switch).

The construction elevator, also known as the construction elevator for the building, can also become an outdoor elevator and a lifting cage for the construction site. Construction hoists are mainly used in various types of urban high-rise and super high-rise buildings, because such building height is very difficult to use well-shaped frames and gantries to complete the work. It is a manned and cargo construction machinery often used in construction, mainly used for the interior and exterior decoration of high-rise buildings, bridges, chimneys and other buildings.

Fiber worker lifts are mainly divided into the following categories:

Overhead lift: It is lifted by hanging or supporting on the overhead structure, and is often used in high-rise buildings, large-scale projects and factories.

Ground lift: It is lifted by moving on the ground by itself, and is often used in engineering construction, loading and unloading goods, handling materials, etc.

Vertical lift: It adopts vertical up and down movement for lifting, and is often used in engineering construction, loading and unloading goods, handling materials and other occasions.

Slope lift: equipment that can move and lift on the slope ground, often used in slope ground, cliff ground and other occasions.

Wanzi Kongsong Wheel Lift: It is lifted by means of universal wheel movement, and is often used in narrow spaces, special-shaped floors and other occasions.

Construction hoist are mainly divided into the following categories:

Overhead lift: This type of lift is mainly composed of an overhead bracket and a lifting boom, which can work at height.

Fixed lift: This type of lift is fixed on the building, mainly used for interior and exterior decoration and maintenance of the building.

Mobile lifts: This type of lift can be moved, and is suitable for external decoration and maintenance of buildings.

Vertical lift: This type of lift has a three-dimensional structure, which is mainly used for the internal maintenance and decoration of high-rise buildings.

Suspended lifts: This type of lift is suspended from a building and is suitable for exterior decoration and maintenance operations.

Desk lifts: This type of lift is fixed on the ground and is suitable for the transportation and loading and unloading of light items.

If your problem is not resolved, please describe your problem in detail.

1. Safe and reliable: the hydraulic transmission system can adjust the speed to ensure the safety performance of the construction hoist.

2. Portable: small and lightweight, easy to transport.

3. Low energy consumption: hydraulic transmission system and low energy consumption. The cooperation between each part greatly reduces the operating cost of the whole machine.

4. Convenient and fast: no foundation treatment is required during installation, and there is no obstacle avoidance after being put into use.

The construction hoist has an advanced drive system, which can not only reduce noise, but also increase the headroom and make the transmission more stable. Have a great day.
