Product Description:

Guangdong Yuhuaxing Construction Machinery Manufacture Co., Ltd., established in March 1997, is a private enterprise specializing in R&D, designing, manufacturing, selling and leasing of construction machinery. Headquartered in Baiyun District of Guangzhou, it is the council unit of Decoration and Aerial Work Machinery Branch of China Engineering Machinery Industry Association and a member of Guangdong Standardization Association, mainly producing builder hoist, mast climbing work platform, superdeck loading platform, temporary suspended platform, building maintenance unit etc.

Description of Safety Lock

1. It is a kind of basic component of Suspended Access Platform. Based upon the working principle, it can be divided into LSB30 anti-tilt ones and LSL30 fall arrest ones.

2. When the steel wire is broken or the platform tilts up to 3 - 8 degrees, the safety lock can automatically and securely lock the steel wire and prevent any person from falling. Even the platform falls down, the safety lock is able to lock the wire within 100mm before it is late. Additionally, it can be powered manually when the hoister or motor goes wrong

Key Features and applications of Safety Lock

well-designed structure, made by superb materials

easy to manipulate

ideal for protection against any falls during work in places of high altitude

- manufactured to the latest GB19155-2003 National Safety Standard

Technical Parameters of Safety Lock

Q:Is the construction elevator a special equipment
The construction elevator is a special equipment. Special equipment is related to life safety, greater danger of boilers, pressure vessels (including gas cylinders), pressure pipes, elevators, lifting machinery, passenger ropeway, large-scale amusement facilities and field special motor vehicles (factory) in these eight types of equipment. In order to guarantee the safe operation of the special equipment, the state of all kinds of special equipment, in three stages: from the production, use, the examination has strict rules, is a whole process supervision. According to a 2013-2017 China special equipment inspection testing industry market foresight strategic planning and investment analysis report statistics, by the end of 2011, the national special equipment comprehensive inspection agency has reached 545, including quality inspection department inspection institutions, industry inspection institutions and enterprises self-checking, in addition to type testing institutions, nondestructive testing institutions, cylinder inspection institutions, etc.
Q:Construction site construction elevator and tower crane, which unit security check and acceptance?
Different but most likely is the construction elevator
Q:The construction elevator relies on what to carry heavy, static hour force point where
Driven by two or three worm gear reducers, the ladder cage is a load bearing unit, and gravity is carried by a rack. At rest, the force point is in the meshing of the gear and rack.
Q:What is the main function of elevator motherboard?
A control system includes light, machine, electric, calculate, calculate the mainboard is mainly responsible for, the equivalent of the human brain, it gathers the elevator running status, corresponding analog signal output, control of elevator running properly and safely.
Q:What about the energy efficiency of the escalator
Construction elevator adopts frequency conversion stepless speed, smooth braking, small impact on the grid, and energy saving effect is obvious, ordinary construction elevator running speed is 36 m/min, motor, 3 * 11 kw; Frequency conversion construction elevator running speed can reach at low speed: 0-46 m/min, motor: 2 * 11 kw, whether in theory or in practical construction, energy saving effect is remarkable, some developed coastal areas in frequency conversion construction elevator as mainstream products has become a trend.
Q:How does the driver of the construction elevator do the search for a sudden power failure
When the elevator is running in an abnormal condition, it should stop immediately and take effective measures to bring the ladders down to the ground floor. When the electric is out of control in operation, the stop button should be pressed immediately. The stop button is not allowed until the failure is ruled out.
Q:There are differences between the construction elevator and the construction elevator
The principle is different, the construction elevator operates in the litter box. The elevators are short for construction elevators, which are very high in the safety and performance of large facilities that can be used on the site. The construction elevator should be a dual-use lifting device.
Q:What is the height of protecting door protection of construction elevator
Referring to the unified code of construction safety technology of GB 50870-2013, and the construction safety inspection standard JGJ59-2011
Q:What are the requirements for the construction elevator
So for safety device factory test is very strict, before delivery by the statutory inspection unit for torque measurement, critical speed measurement, measuring the amount of spring compression, each with the test report, after assembly to the construction lifter for drop test under rated load, and the site to use the elevator must be every three months to conduct a drop test. For safety device to the factory for two years for safety device (delivery date), must also be sent to the statutory inspection unit to carry on the test, after testing once a year.
Q:How long does the construction elevator do a crash test
Construction lifter before put into use, must pass a drop test, using every three months should do a drop test, to adjust for safety device, braking distance will be falling not more than 1.2 m, after test and normal operation of every happening for action, must be to reset the attached safety device. The adjustment, repair, or identification of the anti-falling safety device shall be carried out by the manufacturer or designated authorized unit, which shall be operated by the professional at the time of the crash test. General can at the local special equipment inspection institutions detection, can also be tested in other qualified enterprises, such as: wuhan science, Shanghai special survey, qufu golden horse machinery testing!
