Profile

BB model wall type cantilever crane(hereafter referred as crane) is a kind of crane which can be fixed on the wall or it can travel on the high elevated track way mounted on bearing structure or it can travel alongside the high elevated track way mounted on the wall. Generally, it is installed on the ground floor in the workshop. Because there doesn’t lay any railways on the ground, it can greatly save the ground space in the workshop. The crane is designed and manufactured in according to GB/T 3811-2008 design rules for cranes and JB/T 8906-2014 cantilever crane.

Characteristic

The cantilever of the BB model wall type cantilever crane is not big. The service of the area of the crane is the shape of rectangle, which is mainly used in relatively intensive workshop.

The BB model wall type cantilever crane mainly consists of five main parts, such as cantilever shalving, stand column, cross girder, driven device, electric hoist, trolley and electric equipment. The working principle of all structures and overall machine as following

The cantilever shalving is weld as cantilever girder by structural steel or steel plate, which is the main bearing structure of crane. Generally, the single girder structure equipped with hoist with two trolleys or double girders structure of winch trolley are used to allocate and transfer the hoist. The single girder usually is used in the crane with small lifting weight and small effective cantilever. The double is usually used in the crane with big and effective cantilever.

The purpose of the standing column is used to connect the cross girder and cantilever shalving, which has the function of connecting link.

Cross girder and driven device are the loading and drive parts of the traveling mechanism of the crane. It is divided into traveling girder and anti rolling cross girder. On the traveling cross, main drive device is mounted on. On the anti rolling cross girder, the driven device is mounted on.

The lifting mechanism of the whole BB model wall type cantilever crane contains electric hoist or trolley. The electric hoist used in single girder is mainly made of electric motor, reduction box, winding drum, steel wire rope, hook group, driven carts and other parts. The electric motor of lifting mechanism and traveling mechanism adopts electric motor with conic rotor, which has the good characteristics of heat dissipation, long service life. Also, it is reliable and safe. The material of gear reduction adopts 40Cr with a large loading. The winding drum is made of seamless steel tube with good property. The steel wire rope of the crane is flexible. It must satisfy that the left coiled steel wire rope on the drum must be no less than two rings when the crane is lifted at the max. height. The material of the hook must adopt forged qualitative carbon steel or low carbon alloy steel. And then, the material should be experienced the process of non-destruction testing, metallographic analysis. The type of the kook is single. The mouth of hook must be installed the safety device which is for preventing the hook from falling. The winding trolley of the double girder is mainly up of trolley frame, lifting mechanism, traveling mechanism and etc. The trolley is box-type girder which is welded by steel plate, which is the main bearing structural member. The lifting mechanism is made up of electric hoist for lifting, gear reduction, brake, coupling, coiling block. Steel wire rope, hook group, pulley block and etc. The traveling mechanism is mainly made up of electric motor for traveling, gear reduction, brake, coupling, wheel blocks and etc.

The electrical engineering of the crane mainly is made up of control cabinet of hoist, control cabinet of cart traveling. The designed protection measurement includes range limit, short-circuit protection, overload protection, lack-phase protection, zero position protection, interlock protection and etc. The control method of the BB model wall type cantilever crane contains ground control and remote control.

FAQ

What is the wall type cantilever crane like? Comparing with the pillar type cantilever crane, what is the distinguishing between pillar type cantilever crane and ilever crane?

BB model wall type cantilever crane is a kind of crane which can be fixed on the wall or it can travel on the high elevated track way mounted on bearing structure or it can travel alongside the high elevated track way mounted on the wall. The cantilever of the crane is fixed on the column and rotated by the rotary hinge shaft. Ilever crane is a kind of crane that the cantilever can slewed in line with the rotary column which is mounted on the wall.

How to manufacture bracket and bearing rail beam?

BB model wall type cantilever crane is a kind of special crane, which has a higher requirement about bearing wall and steel structure. The bracket and railway is designed by designing institution commonly, which is manufactured by specialization team. In terms of the old plant, the bracket and railway should be designed by specialized civil design in according to the wheel pressure of supplied the draft. After the wall and steel is checked, it can be designed and manufactured by the specialized team.
