Platform lifting platform hydraulic lifting platform automatic hydraulic lifting platform

The main structures and systems product descriptions high lift mobile hydraulic lifting platform generally have four parts, namely mechanical structure, hydraulic systems, electrical systems and mobile devices. 3.1 Structure of the mechanical structure generally lift from the base, arm and table of three parts. The base is made of welded steel plate corresponding strength; jib is cut vertically hinged brace, made of high strength seamless rectangular tube production, high strength, appearance; a few people at the same table can operate, and a security fence and low manipulation screen, safe and reliable operation. 3.2 Description of the hydraulic system from the pump inlet, pushing the piston cylinder, lifting the cross arm vertical rise, fall time, pressure limiting valve and the oil flow regulator valve under surveillance, back into the tank through the solenoid valve. When the cylinder overload, pump output pressure oil directly back into the tank through the relief valve (valve). In order to prevent uncontrolled fall pipe rupture accident, each cylinder into the oil (oil return doubles) the line (42) provided with a check valve speed, even in the case of rupture of the tubing, but also to ensure the normal lowering speed decreases. See detailed works (hydraulic schematics). 4. Preparation before use 4.1 To ensure safe use, and the unit is in good working condition before use, the performance should be visually checked. Check the contents are as follows: a, the power cord is intact; b, the buttons are effective; whether c, pipelines and other oil leakage; d, each crossing point on the boom nuts are tightened. 4.2 steps a, stretched legs, legs bolt to adjust so that lifts to maintain the level, and then lock the leg positioning bolt; b, power and turned on, the work can be carried out after the first test to be lights. 4.3 Precautions a, according to the provisions of the work load, non-overloading use, not overloaded up to 10% in exceptional cases of emergency; b, in the absence of the security fence in the non-stationary lift table manned work; c, in the course of action and the rise position, not moving lifts; d, lifts work, the legs must be softened, prohibited as intense shaking man on the working platform. e, is prohibited in any live work bench; f, find lifts working pressure is too high or abnormal sound, should immediately stop inspection, in order to avoid serious damage to the lift station. Please refer to the general failure (failure and exclusion); g, when the wind is not more than 5 use and may not use the machine when thunderstorms. 5. Maintenance safety instructions a, non-electrical professionals are not free removable appliances to prevent electric shock or incorrect connections. b, need to enter the following maintenance work platforms lift, you must Diaozhu lift work platforms. To prevent a sudden drop in lift, causing casualties; c, non-professionals can not be adjusted relief valve in the hydraulic system requirements for each component are under pressure after work, arbitrary adjustment relief valve may cause the hydraulic non-functioning system. Of human, machine, material, there will be unnecessary damage; d, before unloading any part of the hydraulic system, you must first relief, in order to avoid pressure oil spray, table suddenly decline; between e, corresponding to the moving parts are filling some lubricants prolong bearing life; f, oil and hydraulic oil check the oil level. Lifts full rise. When this position, hydraulic oil level should be higher than the bottom of 40-50 mm. Hydraulic machine is darkened, sticky or gritty and other foreign matter, if found, should be replaced 120 # hydraulic oil.
