What is Chain Hoist?
Electric chain hoists provide safe movement of loads with the help of manual or electric trolley and hook working on metal beams. Except for metal beams, jib cranes, gantry cranes, overhead cranes, etc. They can also work with structures and can also be used with different and specially designed constructions.
Thanks to their special designs and compact structures, chain hoists take up little space and provide easy use in narrow and difficult areas. Manufactured in accordance with Ts En 150 9001:2008 Standards, they are these economical and reliable, technically innovative secret heroes of the industries.
Gearbox
They provide healthy heat distribution with their aluminum alloy outer structure. Heat treated reduction gear, bearings and steel wheels are designed with high quality.
Self Brake Electric Motor
Conical structured askenkon braking system designed for single and two-speed structures; It provides reliable braking for these products with axial movement.
Chain
It must pass through heat treatment application and galvanization and can be used safely in rain, sea water, chemical environment corrosion. The dynamic working resistance of the crane chains is 80 kg/mm2 and has a flexibility of not more than 10%. Carrying loads are calculated as 2000 Kg in a single equipment. According to the transport weight, their structure changes with the cranes and the number of equipment increases.
Load Sprocket
It has a heat treated structure with five pockets. It ensures the transfer of the force transmitted from the motor via the shaft, and ensures that the load is lifted safely.
Chain Guide (Locator/Remover)
The chain guide is used to insert and remove chain links both inside and outside the pockets, during raw lifting and lowering.
Load Hook Block
Spring load hooks with safety latch are manufactured in cast from high-strength steel and provide the connection and transport of chains and loads on the carrier bearing by means of large-section steel pins. Hook blocks are made of cast aluminum, which provides chain protection with its pocketed structure.
Chain Stop
The chain stop switch is a cast steel product that provides the movement of the lifting unit with the help of shock absorber parts for the chains.
Chain Box
They can be produced from plastic, nylon and steel. The size of the chain varies according to the amount of chain used on the chain hoist, that is, the lifting height and the structure of the transport chain. It is the part that collects the descending parts of the chains.
Overload Limit Switch Device
It is a device that activates when the standard load of Electric Chain Hoists exceeds 20%, ensuring the safety of the load and the environment.
Balancer (Single Chain Lifting Cranes)
The stabilizer is connected to the clutch device and ensures the stability of the lifting unit. It absorbs the heat generated during the gripping movement.
Chain Hoist Brake
It is provided by the brake shoe and its structure, which can be mounted in 3 different sizes, which are protected by a fan system in order to prevent overheating in case of intense operation. The surface slopes of these products, which perform even in the most demanding conditions, and the magnetic field ranges of the pads need to be adjusted correctly.
Distance Limit Switch Device
Distance limit switches, which are found in all electric chains as standard equipment, regardless of the number of chain hardware, are micro switch circuits that ensure the safety of the chain and the load by preventing the chain from being jammed or forced during the up and down movements of the loads.
Suspension
It is an eyebolt mechanism used for lifting sensitive loads. Special production is available by adapting the lifting units to the connection parts.
Electrical Controls
If the lifting unit is supplied with electric control, alternatively its movements can be activated in the following ways:
Low voltage controls include transformer for low voltage power supply of control circuits, general line contactor, contactor for control of hoists and electric carrier motors, transformer protection fuses and terminal blocks for connection of auxiliary circuits and power circuits. The components are housed in a sealed box made of shockproof thermoplastic material with IP 55 protection. The equipment is mounted on the engine side of the hoist.
IP 55 protections are inside the body of impact resistant aluminum material made of thermo plastic; It is located in the engine part of the lifting unit. Low voltage control is possible with the correct operation of Transformer, Contactors, fuses, auxiliary circuits and terminal blocks in an organized manner.
Direct control can only be used for electric chain hoist control for vertical movement control. As in the other option, it is housed in a PI 55 Protected body built in a self-standing, shock and liquid resistant thermoplastic box.
Wired controls are manufactured to be resistant to breaking from the panel. It provides control and command according to the movement of the electric chains.
Carriage
They are the mechanisms that provide the horizontal movement of the loads lifted by the cranes. It is possible to use 3 different types, the first is the manual pull chain trolley, the second segment is the controlled trolley, the “user controlled trolley”. On the subplanning of the beam, the flank is drawn by tightening the bolts for the foundation flank approach. Rail clamps or spikes must be used to derail the trolleys moving on steels that need periodic lubrication.
Chain Hoist Codes
There are options that affect the prices of cranes. The application areas of these special models are height and height. Chain kit is required depending on height from rack loading. In the case of precision mine, it is made double-speed with what is done on the panel and control. If there is a risk that it is in the past and glare class, it should be revised as exproof.
