Hand pallet trucks and electric pallet trucks are flat point-handling tools
10-16
Hand pallet trucks and electric pallet trucks are flat point-handling tools. Compact size and flexible so that hand pallet trucks suitable for almost any occasion. However, due to the manual operation,when electric lift trucks carrying heavy items around two tons more difficult, it is usually for a short distance of about 15 meters frequent operations, especially in loading and unloading area. In the future all aspects of logistics, the manual pallet trucks also will assume the role of convergence between the various transport links, a set on each truck is equipped with a card or hand pallet trucks, will make quicker and more convenient loading and unloading operations, and does not subject to site constraints.
debug conditions: basic boom , boom elevation angle 50

1 debug conditions: basic boom , boom elevation angle 50 lu, lifting the working range under nominal weight to one meter height stop 2 debugging method : toggle joystick to boom up ( down ) position , a slight movement when heavy braking immediately . Continuous ups and downs of boom 10, the cumulative distance measuring horizontal movement of heavy objects , and calculate the average landings per-action arm displacement . Its value should be consistent with the specified value, or should adjust brake reliability and sensitivity ( rope luffing mechanism ) or back pressure in the hydraulic circuit balancing valves and secondary safety valve set pressure ( hydraulic cylinder luffing ) 3 Commissioning Requirements: Lifting relevant agencies to ensure smooth operation , the action is accurate , no crawling , vibration, shock, and driving power increases and other abnormal phenomena : hoisting , slewing and luffing mechanism jog good performance
Crane hook up it up Cause Failure Analysis

In short, to grasp the method, familiar with the principle, first determine the cause analysis to determine the exact location of faults before they can prescribe the right medicine for further inspection and repair, until troubleshooting. Typically, you can slip the hook through the following methods to determine the exact location of faults: When the handle bit appears slide the hook, it can be concluded that the brake failure; when the handle is in the down position appears to slide the hook, it can be concluded that balancing valve failure; when the handle is in slide the hook up position occurs, it can be concluded that a motor or valve failure. In short, to grasp the method, familiar with the principle, first determine the cause analysis to determine the exact location of faults before they can prescribe the right medicine for further inspection and repair, until troubleshooting. In addition to the above, there is no action lifting mechanism, put rope slow, put ropes vibration and other common faults.
lifting machinery to enter the scene after inspection and acceptance

to participate in lifting operations personnel , including drivers , cranes, signal conductor , welders etc should be special operations personnel , must be through professional training, examination to obtain certification, and can be confirmed by the experience of persons in high places . before large-scale lifting operations should be carefully survey the scene , according to the preparation of engineering characteristics and operating environment of special programs, and technical director for approval by the enterprise , which include : on-site conditions and measures to project overview and construction technology , lifting machinery selection basis , lifting derrick design calculations , anchor design, the design of wire rope rigging letter selection , ground and road endurance requirements , component diagrams and stacked in place lifting process in a variety of protective measures. lifting machinery to enter the scene after inspection and acceptance , reassemble the crane should be required to make a trial run , including static and dynamic load tests , and various safety devices sensitive to reliability testing. Derrick after assembly shall be approved by program try hanging test, confirmed to meet the requirements before use.
