Hole, hoisting pad 6 is located at the center of whole sulky derrick.
Figure 10 is that packaged type hangs sulky derrick deck implementation schematic diagram, as illustrated, fixing eye plate in tripod and propping up
In the case that support leg fixes eye plate by bolt and wing nut locking, supporting leg will not be sagging, and staff holds tripod bottom
The reinforcing plate in portion can be carried out on deck plane.
In shipbuilding, packaged type sulky derrick of the present invention includes following step using process：
The first step, packaged type sulky derrick is carried out to using near position by storage location, exists side by side；
Second step, unclamps locking device, tripod is separated with supporting leg；
3rd step, determines the accurate location of 2 foot lands of tripod, is poured onto certain angle；
4th step, adjusts the drop point site of supporting leg, it is ensured that hoisting pad is in center as far as possible；
5th step, is connected tripod and supporting leg with 2 sets of chainlet fixing devices, is selected according to the position of tripod and supporting leg
Suitable little chain length；
6th step, confirms the stability of tripod and supporting leg；
7th step, installs chain block on hoisting pad；
8th step, detaching equipment or part of appliance, start lifting, and are pulled to depletion region nearby, are keeped in repair；
9th step, after maintenance terminates, suspension bracket is moved to depletion region by chainlet fixing device of dismantling, and supporting leg is closed to tripod
Hold together, locked with locking device, turning hanger makes roller be adjacent to ground, lifts tripod, carries out to storage location.
The portable sulky derrick of the present invention is mainly used on ship the equipment relatively small to some appearance and sizes or sets
Standby part is keeped in repair, and packaged type sulky derrick of the invention can not completely replace all lifting suspension brackets on ship or rise
Loser plate, it is only applicable to those lighter in weight（Usually less than 2 tons）, the less big equipment of appearance and size or part of appliance,
For main equipment or part of appliance still need to consider from fixed boom hoisting or hoisting pad, but still have very on real ship
Many equipment can carry out lifting maintenance with this kind of packaged type sulky derrick.
