The mounting hole for installing pin shaft is offered in the middle part of the connecting plate I in the present invention.
The design principle of the utility model is as follows:
It is lifted by crane using the utility model, is not needed replacement suspender, the baudrier for only changing wirerope can be light
Pine nut now lifts by crane being switched fast for multiplying power, so that the lifting article for meeting different weight is pacified with different safe lifting velocities
Full lifting, lifting is high-efficient, lifting is safe, applied widely, structure is simple and convenient to operate, quick for installation, saving suspender expense
With, reduce cost.More specifically, it is newly a kind of cunning by as the capel at wiring consolidation end and wiring guiding role that this is practical
The combined sling to be formed that is combined and installed together is taken turns, and is cooperated with the head wiring auxiliary member for being mounted on arm tower crane,
Can be in such a way that flexible transformation be at a variety of different wire rope windings for lifting by crane multiplying powers, not needing replacement suspender can easily realize
Being switched fast for multiplying power is hung, so that the lifting article for meeting different weight carries out safe lifting with different safe lifting velocities,
Therefore high-efficient, lifting is safe, applied widely, structure is simple and convenient to operate, quick for installation with lifting by crane for the utility model
Feature.Meanwhile the utility model can be achieved with the function of more covering traditional suspender with a set of combined sling, and suspender expense is greatly saved
With reducing production cost.
The advantageous effects of the utility model are as follows:
It is lifted by crane using the utility model, is not needed replacement suspender, the baudrier for only changing wirerope can be light
Pine nut now lifts by crane being switched fast for multiplying power, so that the lifting article for meeting different weight is pacified with different safe lifting velocities
Full lifting, lifting is high-efficient, lifting is safe, applied widely, structure is simple and convenient to operate, quick for installation, saving suspender expense
With, reduce cost.
Technical effect more specifically embodies are as follows:
By the utility model be applied to arm tower crane on lift by crane, substantially by a combined sling instead of
It is cover traditional suspender more, it does not need to replace suspender back and forth time-consuming and laboriously in use, only changes the wiring side of wirerope
Formula can easily realize being switched fast for lifting multiplying power: the wirerope for the use of diameter being for example 24mm changes the wiring of wirerope
Mode carries out the Fast transforms of a multiplying power, two multiplying powers, three multiplying powers, and the rated load weight of crane can be at 8 tons, 16 tons and 24 tons
Between be switched fast, and corresponding safe lifting velocity can also be switched fast corresponding 30 ms/min, 20 ms/min, 10 ms/min,
Applied widely, easy to operate, lifting safety；Especially for the lifting of smallclothes, do not changing electrical system and lifting mechanism
Under the premise of lifting velocity improve 2-3 times, lift by crane efficiency significantly improve；Meanwhile the expense of 8 tons of suspension hooks is at least saved, to work
Cheng Jianshe meaning is very great.
