Jib self-propelled crawler diesel-electric crane DEK-631A
with a lifting capacity of 63 tons, it is intended for construction and installation work, mainly for large-block installation of structures and technological equipment in industrial and civil construction.

The crane is equipped with a main boom of 18 meters in length, which can be extended using the included set of inserts of 6 and 12 meters in length. In addition, when operating a crane with extended booms of 24, 30, 36 and 42 meters, to improve cargo characteristics at long boom radii, the crane can be equipped with an additional suspended counterweight (counterweight) weighing 301 tons.

Booms with lengths of 18, 24, 30, 36 and 42 m can be equipped with a fixed jib 10 m long, with a special hook cage and an auxiliary lift winch rope. The crane can operate in a tower-jib design. In this case, the 36-meter boom is equipped with movable (maneuvering) jib 15.25 in length; 24; 29; and 37.75 meters. In this case, the boom is installed almost vertically with a reach of 5 meters and acts as a tower.

The crane can be moved with a load.

The electrical equipment of the crane can operate both from a diesel power plant installed on it, and from an external three-phase alternating current network with a voltage of 380V. The diesel-electric drive of the crane mechanisms ensures reliable operation of the crane in the most difficult conditions.

The crane is equipped with all the necessary devices to ensure safe operation of the machine.

All crane winches are single-drum and driven by separate electric motors. This allows you to carry out operations with cargo both individually and combined.

All winches are equipped with soft-operating, reliable and compact brakes. This reduces the swing of the load during installation operations.

Highly located blocks of the jib pulley allow the use of winches with drums without special rope handlers. Elongated large-diameter drums allow ropes to be laid in no more than 2…3 layers. This allows you to significantly increase the service life of the ropes.

The large rope capacity of the winches (up to 287 m) allows the crane to be used for work that requires a large depth of lowering of the hook, such as laying concrete structures and blocks on the seabed, constructing underground structures, etc.

Cranes with a load moment of 320 tm class most often work with extended booms (30 m or more). The crane is superior to other analogues in terms of lifting capacity on extended booms. This is especially evident when an additional counterweight is suspended.

All crane mechanisms are covered by a common hood. Covering all mechanisms with a hood is especially necessary when working in northern regions where there is a lot of snow and frequent storms, as well as in areas where there are sandstorms.

The power plant of the crane consists of an economical diesel engine with turbocharging and direct fuel injection with a capacity of 115 hp. With. and a 75 kW generator. During installation work, when even the heaviest loads are lifted, more power from the power plant is not required. Therefore, the optimal diesel power in combination with the possibility of power supply (when possible) from an external electrical network makes the crane highly economical during installation work.

The DEK-631 crane is distinguished by good maneuverability in cramped conditions, which is ensured by a caterpillar drive with independent activation of drive devices. The crane is transported by rail on 3 to 4 platforms. The crane can be transported on roads on 2 trolleys using a tractor-trailer.

The control cabin has an increased volume, which makes it easier to create an improved microclimate when working in cold northern regions, as well as in hot southern regions. When working in cold weather, the cabin floor is heated and warm air is blown onto the cabin walls. When working in hot conditions, cooled and purified air from the air conditioner is supplied to the cabin.

The control levers of the main mechanisms are placed taking into account the requirements of international ISO standards. They are placed conveniently and do not require much effort when turned on. This helps reduce fatigue during long-term work.

The driver's seat can be adjusted in height, longitudinally and backrest.

The driver's cabin, located outside the engine room, helps to minimize noise from the operating diesel engine and machinery. A convenient ladder has been used to enter the cabin, facilitating entry at different positions of the rotating part of the crane relative to the chassis.

The crane is equipped with an electric or electronic (optional) load moment limiter. When lifting loads whose weight exceeds the permissible limit, or when the extension of the boom with the load increases beyond the permissible limits, a limiter is automatically activated, stopping the operating mechanisms. The mechanisms can only work in the opposite direction.

All winch drums are equipped with rope winding and winding limiters, which allow: - limiting the tilt of the boom in extreme working positions; — limit the tilt of the controlled jib (tower version) in extreme working positions; — limit the rewinding of the rope from the main winch; — limit the rewinding of the rope from the auxiliary winch.

The crane is equipped with reliable lifting height limiters for direct-acting hook hangers. When the hook suspension approaches the head of the boom or jib, the winch is automatically turned off. Activation is only possible when descending. The crane's engine room has passages and hatches for access to each mechanism. This greatly facilitates monitoring of mechanisms, maintenance, and changing winch ropes.

To signal the maximum wind force when operating a crane with extended booms and in a tower version (with controlled jib), an anemometer is provided, which by turning on an audible signal warns the operator of a dangerous increase in wind force.
