When the operation and lifting mechanism of an overhead crane are done by manpower, this kind of crane is called a manual overhead crane. Manual overhead cranes work mainly through chain links, which effectively saves labor.
Manual overhead cranes are used in unpowered warehouses, oficinas, etc..

Introdução
The manual overhead crane mainly includes three parts: the main beam, the manual monorail trolley, and the manual chain hoist. It is a rail-type light crane.
The operating mechanism of the manual overhead crane adopts the manual drive form, and the transmission adopts the chain hoist transmission. The main beam is made of I-beam, and the beam is welded into a beam and then welded to the main beam. The manual hoist can lift heavy objects, and the monorail trolley moves along the main beam. Manual overhead cranes can be used to install, repair equipment, and lift heavy objects, especially in unpowered places.

Safeguard
In order to prevent cranes and operators from being exposed to electric current and ensure their safety, three insulating devices are installed on the insulated ponte rolante de duas vigas, which is respectively placed:
Hooks and pulleys;
Lifting mechanism and trolley frame;
Trolley frame and crane.
Estrutura Principal
An isolation crane consists of four main parts, the box-type bridge structure, mecanismo de deslocamento do guindaste, carrinho, peças elétricas, others, etc..
Bridge frame
As the main force component of isolation, the bridge frame mainly consists of double beam, double track, vigas finais, trolley tracks, walkways, railings, escadas, and other metal structures.
The main beams and end beams are structured with the box shape, made of Q235 or Q345 steel, with a minimum thickness of no less than 6 milímetros.
The main beam camber is (1 ~ 1.4) S / 1000, and the maximum camber is position-controlled within a tenth of the central span.
Trolley tracks that lay on the bridge are a whole railway to ensure the smooth moving of the trolley, and the insulating devices are placed between the trolley tracks and trolley wheels to ensure the insulating features of the isolation crane.
Mecanismo de deslocamento do guindaste
The traveling mechanism of isolation crane: During operation, driving wheels never slip; when braking, it is steady and reliable.
Trolley parts
Main and auxiliary hoisting mechanisms of isolation crane have a separate driving device, which can lift and handle loads independently and can coordinate to complete the work of turning loads over. Dual braking is used by the hoisting mechanism.
Safety Protection Device
Overload limiter is installed on the main crane hook, which has the functions of weight display, overload alarming, and automatic power off.
Each mechanism is installed with a closed electro-hydraulic brake while the main lifting adopts dual brakes.
Lifting limit switch, proteção contra sobrecorrente, proteção sem tensão, phase protection, zero protection, interruptor de emergência, the main isolating switch, hatch door interlock switch, bells prompt, and other safety devices to ensure the normal operation of cranes and related personnel personal safety.
A few shockproof lamps can be installed under the bridge frame according to your needs.
