Our specialists have extensive experience in performing such work. They are in the most short terms will be disassembled, transported and, if necessary, installed at a new location. We dismantle cranes of any lifting capacity, which are located both indoors and outdoors.

Dismantling of overhead cranes and crane beams

Operations to dismantle a crane located indoors require preliminary preparation. In the place where the crane will be lowered, it is necessary to remove machines and other mechanisms. In addition, access roads need to be prepared for the truck crane. After this, the danger zone should be fenced off and unauthorized persons should not have access to the work area. Next, prepare special equipment, which is used for securing and lowering structural elements tap.

Immediately before dismantling the crane, our specialists examine all its elements for possible detection of unreliable areas that may be subject to corrosion or be deformed. This makes it possible to take preventive measures to eliminate the possibility of accidental collapse of the structure at the time of its removal.

The process of dismantling a double girder overhead crane includes several stages:

The operator's cabin is being removed;

The motors responsible for moving the bridge are removed;

Dismantling of crane-beams, as well as single-beam cranes, is carried out in the following sequence:

All elements to be removed are carefully lowered and stored in a previously prepared space.

In case of disposal, they are cut into small components, more convenient for lowering and transportation.

Dismantling of gantry cranes

All stages of dismantling a gantry crane are carried out according to a plan drawn up in advance by specialists, which must include such items as:

Creation of a work permit for crane dismantling

The tap is completely de-energized;

The cargo trolley is being removed;

The bridge part is being removed;

The end beams are being dismantled.

Cable routes are dismantled;

Scrap metal or major repairs;

The process of dismantling the structure on the ground completes the work. Remove the engines, movable carriages, supports and other remaining elements.

The cost of dismantling a gantry crane depends on several factors: the weight and design of the equipment, work conditions, accessibility of the installation site. The purpose of disassembling the lifting equipment is also taken into account: for further installation and use or sending for disposal. The cost of dismantling starts from 350,000 rubles per unit.

Dismantling a gantry crane includes dismantling metal structures and crane tracks, removing equipment and disconnecting mechanisms. In the simplest cases, dismantling work consists of collapsing the crane and then cutting it up and removing the remaining construction waste. In this case, the area at the site of the collapse is thoroughly cleaned, and the crane is attached to the bulldozer using cables. After this, the metal is cut using hydraulic shears, and the resulting pieces are sent for processing.

When does the need to dismantle a gantry crane arise?

Dismantling of gantry cranes is necessary in several cases:

worn out or faulty equipment needs to be replaced;
it is necessary to replace outdated mechanisms with newer analogues;
gantry crane needs repair;
a decision was made to demolish the crane;
the crane needs to be transported to another location.

Dismantling a gantry crane is much faster than installing it. However, not in all cases the method of simple dumping with a bulldozer is used. If the crane will continue to be used, there is not enough space to collapse it, and there are buildings or power lines nearby, then you need to call a team of specialists who will dismantle the structure step by step.

Features of dismantling a gantry crane

To dismantle the gantry crane, lifting equipment must be used. Light cranes can be disassembled quickly and easily, but for more massive and complex structures it is necessary to attract an additional team of workers. In addition, an experienced electrician must be involved in the dismantling process.

The steps to dismantle a gantry crane include:

dismantling of electrical equipment and cable routes under the supervision of an electrician;
removing the control cabin using a crane;
dismantling the cargo trolley;
removing equipment from the span;
gradual disassembly of the crane itself - unscrewing the bolts on the support connections, dismantling the supports, etc.

To ensure a high level of safety, all work on dismantling the gantry crane must be supervised by specialists and carried out using two truck cranes. Craftsmen who carry out dismantling must have appropriate documents giving them the right to carry out this type of activity.

Gantry crane dismantling cost

The main feature of the installation and disassembly of a gantry crane is that this design is used in the construction of residential and industrial buildings, at railway stations, warehouses, open bases, industrial sites and other places where continuous production is established. This means that the dismantling of the gantry crane must be carried out quickly and efficiently in order to minimize losses during production downtime.

The price for dismantling a gantry crane includes the use of heavy equipment and payment for the work of a team of specialists. The cost of services depends on the complexity of working conditions and the time allocated for dismantling the crane. In addition, the price of dismantling work will be higher if you need to carefully and quickly disassemble a structure that will be used in the future. And, accordingly, dismantling a gantry crane with an expired service life using the collapse method will cost much less.

Many production organizations have had gantry cranes since Soviet times, which are no longer used for their intended purpose, but have not been dismantled. These giants pose a potential threat, since over time tired metal can simply deform, which can lead to an emergency and even loss of life.

Only qualified specialists should dismantle gantry cranes, as this complex task cannot be trusted to untrained workers. Our company offers a service for dismantling gantry cranes. Moreover, all work will be carried out in compliance with all regulatory requirements.

Dismantling of gantry cranes for scrap metal

Quite a lot of old, worn-out gantry cranes, reloading and construction cranes are used at industrial facilities. Reloading stations have a small height and a fairly small load capacity, due to which their disassembly is carried out quickly and without the involvement of large-capacity specialized equipment. The situation is completely different with building and installation structures. Their disassembly involves the use of special technological techniques, with the help of which the work is carried out quite quickly and accurately.

Procedure for disassembling a gantry crane

When dismantling a gantry crane, first of all, preparatory measures are carried out, including the development of a project. The project indicates all possible nuances of the disassembly procedure: the type and quantity of special equipment used, the timing of dismantling, the number of qualified workers involved and a step-by-step plan for completing the work.

During the dismantling process, special attention is paid to safety and mandatory fencing of the work area is carried out.

The dismantling process itself consists of the following stages:

Turning off the power supply and removing electrical equipment.

The operator's cabin, cargo trolleys are dismantled and all additional equipment is removed.

The crane is lifted using pneumatic devices and the support legs are trimmed.

The crane body is lowered onto the prepared site.

The body is cut and individual parts are transported to the storage location.

Why choose our company to dismantle gantry cranes?

Our company has extensive experience in this field of activity and therefore specialists work according to proven technological schemes that exclude emergency situations.

Purpose of dismantling

Depending on the purpose of dismantling work, the order of its implementation is determined.

Disposal of lifting equipment.

Further operation: major repairs, relocation (relocation of the gantry crane) to a new location, reconstruction of equipment, etc.

In the first case, when the crane is to be scrapped, a more effective and efficient dismantling method can be used. The gantry crane is “filled up” using a bulldozer:

Overturning - if the supports are rigidly connected to the span structure. It is necessary to first prepare and fence off the area where the crane fell.

Folding - first loosen the fasteners of the bridge with the supports and, hooking it with a cable, “fold” the crane, calculating its fall in a given direction.

On the ground, all metal structures are cut, assembled and transported for disposal.

The specialized company "TehKranMontazh" will dismantle the gantry crane in a short time, carefully, in compliance with the requirements

FNP "Safety rules for hazardous production facilities that use lifting structures" dated November 12, 2013 and RD 22-28-37-02.

Thanks to extensive experience, TechKranMontazh specialists have developed universal technologies for dismantling lifting equipment of any type.

Dismantling of gantry cranes taking into account further operation

This type of work is considered the most labor-intensive and is performed in compliance with a strict sequence of actions. The stages of dismantling a gantry crane are carried out in accordance with a pre-drawn up plan, which is developed after inspection and examination of the equipment:

Development of a work permit for the dismantling of a gantry crane.
Preparation of supports, sleeper nets, etc. - that is, the platforms where the crane will be lowered.
De-energizing, disconnecting electrical appliances, dismantling cable routes is carried out by a specialist electrician.
The preliminary dismantling of the cargo trolley and operator's cabin will allow the weight of the structure to be significantly reduced. They are removed using truck cranes.
Loosening of the connections between the crane supports and the span structure. The bridge is first engaged on both sides (near the supports) by truck cranes. After loosening the connections, the span structure is smoothly lowered by truck cranes onto the prepared pylons/supports, while the supports come out from under the bridge due to the movement of wheeled trolleys along the rail track.

The final stage of dismantling a gantry crane is carried out on the ground: dismantling metal structures, disconnecting engines,

Mobile carts, supports, etc., loading and removal of equipment.

The TekhKranMontazh company also provides the following services:

Dismantling of gantry and semi-gantry cranes.

Dismantling of gantry container cranes.

Dismantling of gantry grab cranes

Dismantling of double girder gantry cranes.

Dismantling of single girder gantry cranes.

“TehKranMontazh” additionally offers the service: transfer/relocation of a gantry crane to parallel rail tracks.

The use of modern technologies and auxiliary lifting equipment allows work to be completed as quickly as possible, without reducing the productivity (no long-term downtime of the PMG) of the enterprise.
