Standard Headroom Wire Rope Hoist WHTB type

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 standard headroom wire rope hoist, also known as a conventional wire rope hoist, is a type of lifting equipment commonly used in various industrial applications where vertical clearance above the load is not a significant concern. Unlike low headroom hoists, which are designed for applications with limited overhead space, standard headroom wire rope hoists have a more traditional design with a greater vertical profile. These hoists are suitable for lifting and moving heavy loads in areas with ample headroom.

Key features and characteristics of a standard headroom wire rope hoist include:

• Design: Standard headroom wire rope hoists have a design that provides more vertical clearance between the hoist's top attachment point and the uppermost part of the hoist body. This design allows them to operate in areas with standard headroom requirements.
• Wire Rope: Similar to low headroom hoists, standard headroom hoists use wire ropes made of high-strength steel or other durable materials for lifting and lowering loads. The wire rope is wound onto a drum, which is powered by an electric motor.
• Electric Motor: Standard headroom wire rope hoists are typically electrically powered, with an electric motor that provides the lifting force. Electric hoists offer precise control and ease of operation.
• Load Capacity: These hoists come in various load capacity ratings, ranging from a few hundred pounds to several tons, allowing them to handle a wide range of lifting tasks.
• Control Options: Operators can control the hoist using various methods, including pendant controls, push-button controls, or remote controls, depending on the specific model.
• Safety Features: Standard headroom hoists are equipped with safety features such as overload protection to prevent lifting loads beyond their rated capacity, limit switches to prevent over-travel, and emergency stop buttons for immediate shutdown in case of an emergency.
• Attachment Options: They can be equipped with various types of hooks, attachments, or trolley systems to suit the specific needs of the application.
• Trolley System: In many cases, standard headroom wire rope hoists are used in combination with trolley systems that allow for horizontal movement of the load. Trolley systems can be manual or motorized, depending on the requirements.
• Duty Cycle: The duty cycle of the hoist indicates the amount of time it can operate continuously without overheating. Different hoists are designed for different duty cycles, with some suitable for continuous use and others for intermittent use.
• Versatility: Standard headroom wire rope hoists are versatile and can be used in various lifting and material handling applications, including manufacturing, construction, and warehousing.

When selecting a standard headroom wire rope hoist, it's essential to consider factors such as load capacity, control options, safety features, and compatibility with the available space and attachment points. Proper training and adherence to safety guidelines are crucial when operating these hoists to ensure safe and efficient lifting operations.

Selection Criteria
The size of the hoist is determined by the load spectrum, average operating time, safe working load and rope reeving.
1. What are the operating condition ?
2. What are the speficied safe working load ?
3. To what height must the load be lifted ?
4. What is the required lifting speed ?
5. Do the loads need to be lifted and lowered with great accuracy ?
6. Is horizontal load travel necessary ?
7. How is the hoist to be controlled ?
