Double Girder Wire Rope Hoist WHDD type

H-Lift Double Girder Wire Rope Hoist WHDD type
A double girder wire rope hoist is a type of lifting equipment used in industrial settings to lift and move heavy loads. It consists of a pair of horizontal girders (beams) that run parallel to each other and a wire rope hoisting mechanism positioned between them.

An electric wire rope hoist is a mechanism that uses a wire rope or cable fixed to a rotating pulley to raise and carry heavy items. A hook is attached to the cable's end and used to grapple onto an object to be lifted. The pulley is connected to a motor that is controlled by a hand controller. The wire rope hoist lifts an obstacle by rotating a pulley that coils the cord around it. Many types of hoists include a trolley mechanism that allows the pulley and motor to drive around a track, making it easier to move heavy objects.

Double girder wire rope hoists provide additional stability for the manufacture and transportation of heavy loads, as well as have the potential to operate more frequently. Double girders wire rope hoists have increased hook height, better headroom dimensions, and greater crane span capability. They are highly durable and can carry loads reliably and precisely.

ALWAYS:
• Store and handle power operated blocks correctly.
• Inspect the block and accessories before use and before placing into storage.
• For top hook suspension, use hooks that are fitted with safety catches or mouse the hook and ensure the support fits freely
into the seat of the hook.
• For trolley suspension, ensure the trolley is correctly set for the beam width.
• Check that the bottom hook will reach its lowest point without running the chain or rope fully out.
• Raise the load just clear then halt the lift to ensure the integrity of the block before continuing with the lift. If the block has more than one speed, start in the slow speed.

NEVER:
• Expose power operated blocks to chemicals, particularly acids, without consulting the supplier.
• Expose power operated blocks directly to the elements, water spray, steam etc without consulting the supplier.
• Replace the load chain or rope with a longer one without consulting the supplier.
• Use the load chain or rope to form a sling.
• Change motions without first allowing the motor to stop.
• Allow persons to ride on power operated blocks.

Selecting the Correct Block
Power operated blocks are available in a range of capacities, designs and suspensions with electric or pneumatic power
options. Select the block to be used and plan the lift taking the following into account:
Type of block - chain, wire rope - electric, pneumatic - class of use - capacity and range of lift etc.
Type of suspension - hook, trolley, fixed.
Speeds and control - single speed, dual speed - pendant push button, pull cord, remote etc.
Power operated blocks are designed for vertical lifting only.
Consult the supplier if the block is to be used in areas of high risk, exposed to the elements, water, steam etc, with hazardous
substances, eg acids or chemicals, or subjected to extremes of temperature.

Storing and Handling Power Operated Blocks
Never return damaged blocks to storage. They should be dry, clean and protected from corrosion.
In the case of blocks used for temporary applications, store them on a purpose made rack or suspended from their top suspension fitting. Trailing cables, pendants etc may be removed, identified and stored separately to prevent loss or damage whilst in store.
In the case of blocks left in situ, park the block in a suitable position so that it is protected from damage and does not present a danger. Raise the bottom hook so that it is not a danger to persons or liable to become accidentally engaged.
Isolate the power supply.

Installing and Commissioning
Follow the specific instructions for installation and commissioning issued by the supplier and the general requirements given overleaf. Ensure the controls work in the correct direction and that motion limits are set and operate correctly. If the block fails to operate correctly contact the supplier.

Using Power Operated Blocks Safely
Do not use defective blocks, slings or accessories. Check the slinging arrangement, that the block is safely rigged, that the chain or rope is not twisted and that the load is free to move.Raise the load just clear, halt the lift to ensure the integrity of the block, slinging arrangement etc. Always commence lifting in the slow speed. Avoid unnecessary inching of the load.
Check the travel path is clear and that you have a clear view so as to avoid accidental hook engagement or collision. Follow any
particular site safety rules applicable to the movement of suspended loads.

Keep fingers, toes etc clear when lowering loads.

In-service Inspection and Maintenance
Follow the specific instructions for maintenance issued by the supplier. These should be incorporated into the site maintenance programme observing any particular needs due to the site or working conditions.
Regularly inspect the block and, in the event of the following defects, refer the block to a Competent Person for thorough
examination: operational faults; block will not lift; slips back; motion commands reversed; over-runs when command released; wear; damage to trolley, hooks and fittings; damaged, worn or corroded chain or rope; other visible defects.

A double girder wire rope hoist is a type of lifting equipment used in industrial settings to lift and move heavy loads. It consists of a pair of horizontal girders (beams) that run parallel to each other and a wire rope hoisting mechanism positioned between them. Here are some key features and components of a double girder wire rope hoist:

• Double Girder: The double girder configuration provides increased stability and lifting capacity compared to a single girder hoist. It allows for heavier loads to be lifted safely.
• Wire Rope: The hoisting mechanism of this type of hoist typically uses wire ropes to lift and lower the loads. Wire ropes are strong and durable, making them suitable for heavy-duty applications.
• Hoisting Mechanism: The hoisting mechanism consists of a drum onto which the wire rope is wound. The drum is connected to a motor and gearbox assembly that provides the power to lift and lower the load.
• Trolley: A trolley is used to move the hoist horizontally along the length of the girders. This allows for precise positioning of the load.
• Controls: Double girder wire rope hoists are typically operated using a control pendant or a remote control. These controls enable the operator to raise, lower, and move the load with precision.
• Safety Features: Hoists are equipped with safety features such as limit switches, emergency stop buttons, and overload protection to ensure safe operation.
• Applications: Double girder wire rope hoists are commonly used in various industries, including manufacturing, construction, steel mills, and warehouses, for tasks such as lifting heavy machinery, materials, and components.
• Capacity: These hoists come in a range of lifting capacities, from a few tons to several tons, depending on the specific application requirements.
• Durability: Double girder wire rope hoists are designed to withstand harsh industrial environments and provide long-lasting performance.
• Maintenance: Regular maintenance and inspections are essential to ensure the continued safe and efficient operation of the hoist.

When selecting a double girder wire rope hoist, it's important to consider factors such as the weight and size of the loads you need to lift, the required lifting height, and the operating environment to choose the right hoist for your application. Additionally, adherence to safety regulations and guidelines is crucial to prevent accidents and ensure the well-being of operators and workers.
