Often there are some accidents in lift heavy and lift heavy traveling, and the speed of traveling is also fast compared with crawler crane；Operation is stable, lifting capacity is big,
Lift heavy it can walk in particular range but must assure that path formation is solid, tire pressure meets the requirements, hangs ground and must not surpass
Cross 50CM；On-load is forbidden to walk over long distances.To ensure job safety, the country substantially forbids not making a jack being lifted at present
Operation.Crane matches steel wire rope kind and includes phosphorized coating steel wire rope, galvanized steel wire rope and bright wire rope.Bridge-type rises
Heavy-duty machine is that crossbearer carries out the lifting equipment of material handling in workshop, warehouse and stock ground overhead.Due to its both ends be located at it is tall and big
Concrete column or metallic support on, shape is like bridge.The crane span structure of bridge crane along be laid on both sides it is overhead on track longitudinal direction
Operation, can make full use of the space handling material below crane span structure, not hindered by ground installation.It is use scope it is most wide,
A kind of most hoisting machinery of quantity.
Current crane hoisting efficiency is low, can not be worked continuously and speed is non-adjustable, can not meet the need of people
It asks.
Utility model content
The purpose of this utility model is to provide a kind of engineering gantry cranes, are risen with solving crane of the prior art
It is low to rise efficiency, can not be worked continuously and the problems such as speed is non-adjustable.
To achieve the above object, the utility model provides following technical solution：A kind of engineering gantry crane, the bottom of including
, pylon is installed, and tower top is provided with sphere on the pedestal, lifting boom, and lifting boom are provided on the sphere
One end be fixed with lifting horse head, lift shaft is installed, and lift shaft passes through steel wire rope and carrying on the lifting horse head
Device is fixedly connected, and suspension hook is equipped on the carrier, and leading block is provided with above carrier, is pacified on the lifting boom
One end equipped with lifting mechanism, and lifting boom is fixed with raising wheel shaft, and the raising wheel shaft is connected by control-rod with truss arm
It connects, and support column is fixed on the right side of truss arm, the truss arm is rotatablely connected by guide rod and idler wheel, and idler wheel passes through skin
Band is connected with driving motor.
Preferably, the base lower surface is provided with driving crawler belt.
Preferably, set fluted on the leading block, and groove is mutually chimeric with steel wire rope.
Preferably, the pylon is welded by bar material.
Preferably, the driving motor bottom is installed with support base.
Compared with prior art, the beneficial effects of the utility model are：The utility model crane can be by two or more
Platform crawler crane is made up of attachment device, when lifting capacity is smaller, can conveniently by crawler crane disassemble for
Two or more crawler crane operations, the advantage with multiple combinations form, the conversion of multi-state, conventional track crane
Principal arm angle is both less than 90 °, and in lift heavy, it can bear the component of weight and pulling plate, and principal arm bears pulling plate component at this time, this
A power is inefficacious, necessarily reduces the percentage that principal arm bears weight component, and virtuous energy is carried so as to reduce principal arm
Power, and in the gate-type boom system of the crane, jib angle is 90 °, and stressing conditions are preferable, carry percent efficacy
Greatly, complete machine lifting capacity is more than the sum of two or more crane biggest lifting capacities.
