Gantry crane lifting the main purpose of the composition described

Tower
By the angle, steel crane welded steel group, is to enhance the machine's column, by a plurality of the tower section between the M16 screw seized with four connected components, the main role is to gondola wheel running rail, shelf height by the user depending on the desired use of highly own choice, did not increase 3M, the need to increase two tower, subtract and vice versa.
Install the operating platform
By the angle, channel, welded steel group with rollers, pulleys, since turning pallets protection devices, self-loading derrick installed fixed platform can be used to increase or decrease derrick tower, in order to achieve the lifting electric windlass ,  overhead gantry crane  tower column always fused the two is the lifting height of the main body, but also enhance the machine Tian Liang.
DIY derrick
By a group of seamless and welded steel plate, top with pulleys, hand-cranked mechanism, mainly used for lifting tower and pulleys hat head.
Hat head pulley
By the angle and welded steel group, with the main hoist rope pulley is mainly used for orientation.
Hoist
The basket to enhance the power machine body can be fixed to the steering wheel mounted on one side, belonging to a separate supporting body.
Attachment fastener
Seized by the hook screw, pressure level, angle components, mainly for steel pipe and scaffolding tower fixed fastened the other end to connect with the universal fastener for fastening fixed scaffolding and buildings, forming a pivot attachment, thus ensuring mast at higher lifting height to work smoothly.
Basket
Mainly to enhance the material's main working bodies: the angle, channel group welded with wheel, rolling along the tower column chord track, and its guiding role, is also a tension spring card board broken rope protection devices and manual fork stop layer devices, extension spring card board broken rope hanging in the tower protective devices on both sides of the card.
Chassis
Main frame body chassis and steering pulley fixed base, sino hoist the channel steel, welded steel group, the steering wheel can be rotated around the tower side to do the 180 easy hoist positioning.
DIY derrick base
By a group of seamless and welded steel, mainly for the gin pole positioning and fixation.
