Beam crane in English. It is a type of crane. Widely used for lifting goods in different occasions such as factories, warehouses, and material yards, it is prohibited to use it in environments with flammable, explosive, and corrosive media.

Chinese name for beam crane

Foreign name: Beam Crane

A type of crane with properties

Used for factories, warehouses, and material yards

brief introduction

A beam crane is a type of crane that has the characteristics of a lifting mechanism and is a machine that performs cyclic and intermittent movements. A work cycle includes: the retrieval device lifts the item from the retrieval site, then moves horizontally to the designated location to lower the item, and then performs reverse motion to return the retrieval device to its original position for the next cycle.

classification

Beam cranes mainly include single beam bridge cranes and double beam bridge cranes

Single beam bridge crane

The main beam of a single girder bridge crane bridge is often made of I-shaped steel or a combination of steel and steel plates. Crane trolleys are often assembled using hand pulled hoists, electric hoists, or hoists as lifting mechanism components.

There are two types: bridge supported and suspended. The former bridge runs along the crane track on the vehicle beam; The latter's bridge runs along the crane track suspended under the factory roof. Single beam bridge crane comes in two types: manual and electric. The working speed of each mechanism of the manual single beam bridge crane is relatively low, and the lifting capacity is also small. However, its own weight is small, which makes it easy to organize production and has low cost. It is suitable for situations where the carrying capacity is not large without power and the requirements for speed and productivity are not high. The manual single beam bridge crane uses a manual single track trolley as the running trolley and a chain hoist as the lifting mechanism. The bridge is composed of a main beam and end beams. The main beam is generally made of a single I-beam, while the end beam is welded with steel sections or steel plates formed by compression bending.

Electric single beam bridge cranes have higher working speed and productivity than manual ones, and also have a larger lifting capacity. The electric single beam bridge crane consists of a bridge frame, a large vehicle operating mechanism, an electric hoist, and electrical equipment.

Double beam bridge crane

The double girder bridge crane consists of a straight rail, a crane main beam, a lifting trolley, a power transmission system, and an electrical control system, and is particularly suitable for conveying materials in a flat range with large suspension and lifting capacity.

What should be mentioned is the bridge crane, which is divided into single beam bridge type and double beam bridge type. Beam cranes do not have this classification.

Bridge cranes and beam cranes have different lifting capacities, with beam cranes weighing 5t or less and bridge cranes weighing 5t or more.

Operating procedures

1. The maintenance crane must be operated by a specially trained and approved person by the competent department.

2. Crane operators must be familiar with the mechanical and safety performance of the crane they are operating, familiar with and strictly follow the crane operating procedures and safety regulations, proficiently master the lifting operation skills, and must concentrate, obey commands, and operate cautiously during operation.

3. When operating the crane, the operator must obey the command of the commander, and for emergency stop signals, they should be immediately executed regardless of who sends them.

4. Before each use of the crane, the operator must first check the brakes, hooks, wires, etc. of the crane
