Product Description:

HMLK-2800C anti-collision and zone protection system is applicable to almost all brands and types of construction tower crane hoisting,which can be installed and utilized so conveniently.This system adopt the 7 inch computer touch LCD screen,shows the visual and clear picture covering the state of site,dynamic operation picture and the current data etc,promising an effective and safe running for the operator.This system will show real-time trolley range(slewing angle),hoisting weight,hook height,rotation angle,moment rate,wind speed and so on,and pre-alarm or interference before the crane be in violation working.Through remote GPRS module,the system will transmit the real-time working data to the server.The customer will check and manage the real-time tower crane operation remote all over the country by the WEB browser;and also through the GPS module,will locate the accurate position of tower crane.Meanwhile,HMLK-2800C system hardware adopts module design,to assist the integration of high wireless communication equipment,high-precision digital orientation,angle sensor and so on,which promise a stable and reliable sensor system.

The HMLK-2800C series of products applicable to all level-jib,hammer head and luffing tower crane.


HMLK2800C system can be installed and utilized so conveniently.The on-site parameter setup of site and tower crane is simple and humanistic.You can finish the complete input about the tower crane data, prohibited zones,obstacle and boundary,making use of ground level portable computer,uploading all the parameters by a wireless network in a while.It is out of need for the system manager to deal with it by climbing up to the tower crane.While in use,if the height parameter changes,it just need to change the data and upload them wirelessly in the portable computer,however,it has no effect on the normal running of this system.Meanwhile,this system can be used as monitoring equipment,viewing the running state of this system clearly and directly.The friendly procedure screen can show the clear working state of tower crane which were installed with HMLK2800C system.

Temperature of working environment-40 °C~60 °C
Humidity of working environmentbelow 95%(25 °C)
Combined error of the systemwithin ± 5%
Supply voltageAC150V~270V
Data showingrated load,actual load,trolley range(slewing angle),rotation angle,hook height,wind speed and moment rate,group tower crane state
Pre-alarmyellow light stand for pre-alarm,buzzer sounding on and off;red light stand for alarm,buzzer sounding long time,relay output,stop the operating
Functiongraphic display,historical  notes check,sensor self-diagnostic,remote monitor,appling to all kinds of level-jib hammer head tower crane
Remote monitoring and GPS locationthrough the GPRS remote monitoring,real-time monitoring of tower crane operation,GPS global positioning



If the tower cranes are with the same height: this system can control and handle it effectively,once detecting that the running jibs interference with each other automatically.

While not with the same height: this system can also work effectively once anticipating the hook or cable of the higher tower crane may collide the jib or counter jib of tower crane.


Due to the complexity of some sites,the system can automatically and effectively determine up to 10 prohibited zones in which the hook or jib are not allowed to operate.


HMLK2800C system allows the operator to work at maximum efficient way and optimize the use of crane.Once monitoring the pre-set data for possible collision in crane interference area and over-flying of sensitive areas,there will be pre-alarm,visual and audible alarm,and the system will stop the operation automatically to maintain a safety margin.


Advanced communication protocol promises a high speed wireless communication link,and supports an independent network communication.Management capacity up to network control 20 sets of tower cranes.Reliable wireless communication distanced not less than 1.5 KM. Capable to remotely monitor or upload changed the tower crane data by PC in office at anytime,no have any impact on system's operation.

Note: HMLK2800,HMLK2800B,HMLK2800C optional functions

Identification function of IC card,fingerprint and puil of the operator.Wind speed,Tower crane remote locking,GPS global positioning and so on.

Q:What are the mixing arms of the concrete mixer?
Concrete mixer parts often due to operational mistakes and equipment damage, we should know that the correct use of Yantai mixer parts, mixing arm not only can complete the "workload" on time, but also to extend the service life
Q:What are the principles, performances and uses of the commonly used construction machinery equipment?
3. excavator principle: Excavator through the hydraulic pump to the power of the engine to hydraulic motors, hydraulic cylinders and other executive components, to promote the operation of the device, so as to complete all kinds of operations. Performance: new Isuzu engine, euro II emission, international standards, more into power for you, lower fuel consumption; with high torque rotary mechanism, improve the starting torque of rotary and rotary reducing drift; with a new high efficiency, low noise, large displacement of the main pump, provided high efficiency machine to deal with the bad working conditions; and to strengthen the work of device according to the quarry condition, increase its reliability; strengthen the lengthened crawler frame, while reducing the ground pressure, improve the performance of the fault diagnosis system; new, prolong the overhaul cycle, reduce maintenance cost. Use: 1) building and building foundation excavation; (2) mining soil, stripping mining field covering layer; (3) the quarry, tunnel, underground powerhouse and heap loading operation in the field of material; 4) excavation channel, canal and waterway dredging; (5) replacement of the devices can be pouring lifting and installation, piling, rammed earth etc..
Q:Definition of large mechanical equipment?
Depending on the size of the part to be machined, the parts must be set up as large equipment with the aid of a crane, and large machinery is usually assembled after the parts have been delivered to the destination. Material handling machinery is mainly in enterprises (including terminals, materials, mines and commercial warehouses, etc.) within the material handling, transportation, lifting, stacking and storage of machinery and equipment
Q:What type of industry does the machinery and building accessories processing belong to?
There are only three tax categories in our country: 1 consumption tax, 2 VAT, 3 special tax (agriculture). Therefore, as long as the manufacturing or processing of industrial value added tax on enterprises. It has nothing to do with the economic nature, classification and categories of an enterprise.
Q:Construction Engineering, moving equipment and stationary equipment, respectively
1, moving equipment refers to the rotating device driven by the drive (that is, energy consumption of equipment), such as pumps, compressors, fans, etc., the energy can be electric power, pneumatic power, steam power, etc..
Q:What functions should be achieved in mechanical structure design?
Mechanical structure design plays an important role in mechanical design. This chapter mainly discusses the characteristics, steps and mode of thinking of mechanical structure design. The working principle and design requirements of the machine assembly is a major factor in determining the structure and shape of the parts, followed by the selection of materials, manufacturing process requirements, which has the advantages of good manufacturability (processing and assembly). In addition, the perfection of the structure and shape of the parts has a great influence on the strength and stiffness.
Q:What is the difference and connection between equipment manufacturing and machine building?
In accordance with the standards of classification, including metal products, general machinery manufacturing, machinery manufacturing, transportation equipment manufacturing, electronic and communication equipment manufacturing industry, electrical machinery and equipment manufacturing, instrumentation and office machinery manufacturing seven deducted 186 small consumer related manufacturing industry after class. Equivalent to the European countries referred to as "capital goods manufacturing", that is, we often say "the production of means of production industry."".
Q:Where are the hanging baskets for the building?
It is forbidden to take a stool or put a ladder on a hanging basket to work higher; it is not allowed to work alone in a basket, and no electric machinery or equipment can be placed in the basket;
