Thin type hydraulic jack
Hydraulic jack using note matters:
a: hydraulic jack in top rose job Shi, to select right tonnage of hydraulic jack: hosted capacity not overload, select hydraulic jack of hosted capacity needed is greater than weights gravity of 1.2 times times; hydraulic jack minimum height right, to easy out, selection hydraulic jack of minimum height should and weights bottom Shi force at of clearance phase adapted, landing process in the pad sleepers support weights Shi, hydraulic jack of up rose height to is greater than sleepers thickness and sleepers deformation of and.
II: If using more than one the same device of hydraulic jack and lift, hydraulic jacks of the same type should be used, and each of the rated capacity of the hydraulic jack and assume equipment shall be not less than 1.5 times of gravity.
III: hydraulic jacks should be wiped clean before use and check all parts are flexible, with or without injuries, quick connector should not be unloaded when the load to avoid accidents and damage to parts.
four: hydraulic jack in using Qian should placed flat, cannot tilt, bottom to pad flat, prevent Foundation partial sank or load offset and makes hydraulic jack tilt or overturned, can in hydraulic jack bottom pad tough of Pillow operation or plate to expanded bearing pressure area, so as not to fall or sliding and occurred accident; do not with has oil of wood or plate as liner, prevent by force Shi skid, occurred security accident; weights was top rose location must is security, and solid of parts, case damaged equipment.
five: when using hydraulic jacks, you should lift the try part, carefully examined after hydraulic jacks is no exception, and then continue to lift weights. If the pad compression uneven, unstable or hydraulic jacks when hydraulic pressure relief must be return, good deal before once again operation.
VI: in the process of lifting, along with rising weight in foreshadowing insurance sleeper beneath the hydraulic jack to prevent hydraulic jack tilted or accidents causing the piston down, lower weights to gradually draw out sleepers, sleepers shall not exceed a distance between the weight and thickness of the sleepers, in case of accidents!
: the heavy lifting height required exceeds the rated altitude of hydraulic jacks, first in the hydraulic jacks weights underlying good sleepers, lowering hydraulic jack, padded bottom, repeat the lift until required lifting height.
BA: hydraulic jacks should not be used as a permanent support device. If you need support for a long time, should load sustaining parts increases under, to ensure that the hydraulic jack from being damaged.
IX: If lifting weights at one end only when using a hydraulic jack, hydraulic jack should be placed on the axis of symmetry of the weight, and hydraulic jacks long base and heavy dumping in the same direction. If two hydraulic jacks are used on the heavy end, it should be slightly in the direction of the base eight-shaped symmetrically arranged in heavy axis of symmetry on each side.
10: use two or more hydraulic jacks and lifting operations shall be unity of command, coherence, and lift.
11: hydraulic jacks should be stored in a dry, dust-free place, not suitable for acid and alkali, corrosive gases used in the workplace, should not be placed outside in the rain!
actions should be in strict compliance with technical specifications, user needs periodic inspection and maintenance based on usage.
