Truck lifting equipment parameters is a set of technical data characterizing the structural features of the machine. The article is prepared in collaboration with Granada Material Handling, a seasoned UK-based business specialized in cranes manufacturing, lifting equipment inspection and lifting equipment services.

So, the main parameters include boom length, radius and height of the cargo hook load capacity, load moment, the speed of lifting and lowering and rotating the rotary part of the crane.

Boom length is the distance (in meters) between the centers of the heel axis and the axis of the boom head blocks. Boom length and its angle on the inclination to the horizon defines teh reach and hook height.

Departure load hook – the distance (in meters) from the axis of rotation of the crane to the vertical axis passing through the center of gravity of the lifted load (bottom block). Free flight hook – the distance (in meters) from the edge of tipping to the vertical axis passing through the center of gravity of the lifted load.

Hook height – maximum height to which you can raise the hook above the platform on which the crane at the operating position of the boom.

Lifting capacity is the maximum weight of the load that can be lifted by crane without breaking the strength of its design and buckling. The value of load capacity depends on the length of the boom and the departure of the load hook. In mobile cranes lifting capacity with the least radius of the hook several times higher than the load capacity at the maximum radius of the hook.

Load moment is defined as the product of the settlement and the load bearing capacity of the crane by the amount of the departure of the hook, in which the cargo is lifted. Load moment is measured in tonne-meters; this parameter characterizes the technological possibilities of the crane as well as indicates at what distance from the axis of rotation of the crane can be placed a weight corresponding to the departure of the hook.

The speed of lifting and lowering is the value of the load path of movement (in meters) per unit time vertically. It is measured in meters per minute (m/min) or meters per second (m/sec).

The rotational speed of the rotary is measured by the rotary part of the crane in a unit time (rev/min).

Organizing the trouble-free functioning

The organization of the truck crane operation implies using a system of measures to ensure their rational use of equipment at the lowest cost of labor and providing quality work in the planned dates in compliance with the safety requirements. Work truck crane is organized in accordance with the project of works, which is typically based on the adopted instructions and the best practices within these machines in the niche industry. The activities carried out by automobile cranes are a part of a single process in the construction reduced to three types of work: handling, assembling and vertical transportation of materials.
