Equipment assembly process chain hoists

1  manual hoist  preparatory work prior to assembly
(A) research and technical conditions are familiar with assembly drawings to understand the chain hoist role of product structure and components, as well as connected to the relationship.
(2) determine the assembly methods, procedures and tools needed.
(3) collect and cleaning parts.

2  chain block  assembly
Another component assembly assembly, parts assembly and final assembly of the points, the entire assembly process should be carried out in sequence.
(1) The module assembly of certain parts are mounted on a base part on which the constituent components. If a speed reducer shaft, on the shafts, gears, keys and other parts assembled components.
(2) chain hoists parts assembly will be a number of parts, components, parts installed on another basis on which constituent parts (an independent body). Such as lathe headstock, feed box, tailstock.
(3) general assembly will be a number of parts, components, parts combined into the whole machine called a general assembly during operation. Such as lathes is to combine several cabinet and other components, assemblies, parts combination.

3  Chain Block  assembly work requirements
(1) assembly, parts and assemblies should be checked on the shape and dimensional accuracy is qualified to check for deformation, damage, etc., and should pay attention to the markings on parts, to prevent the wrong equipment.
(2) fixedly connected parts, does not allow a gap. Moving parts, in a normal gap, the flexibility required direction uniformly, there should beat.
(3) of the moving part (or parts) of the contact surface, must ensure adequate lubrication, if the oil must flow.
(4) a variety of pipes and sealing parts, after assembly shall not have leakage.
(5) test, should check a component connection reliability and flexibility of movement, the joystick is flexible and handle position is in the right position; prior to commissioning, from low speed to high speed gradually.
