H-Lift Low Headroom Wire Rope Hoist WHLB type

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.

Headroom is the space from the point on the hook where the load will be hanging to the point where the hoist, or hoist and trolley, connects with the support member the hoist hangs from. This can often be an I-beam such as a horizontal building support or some kind of crane such as a jib crane or gantry crane.

Safe Use of Power Operated Hoist

• 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.

• 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.

Low Headroom Wire Rope Hoist

A low headroom wire rope hoist, also known as a low headroom trolley hoist or low clearance wire rope hoist, is a type of lifting equipment designed for use in applications with limited vertical clearance above the load. These hoists are specifically engineered to work in areas where traditional hoists with higher headroom requirements cannot be accommodated. They are commonly used in industrial settings, manufacturing facilities, and construction sites where space constraints are a concern.

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

  • Compact Design: Low headroom hoists are designed to have a reduced vertical profile, allowing them to fit into tight spaces with limited overhead clearance. This compact design is achieved by minimizing the space between the hoist's top hook or attachment point and the uppermost part of the hoist body.
  • Wire Rope: These hoists utilize wire ropes made of high-strength steel or other durable materials to lift and lower loads. The wire rope is wound onto a drum, which is powered by an electric motor.
  • Electric Motor: Low headroom wire rope hoists are typically electrically powered, with a motor that provides the lifting force. Electric hoists offer precise control and are easy to operate.
  • 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: Low 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, low 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: Low headroom wire rope hoists are versatile and can be used in various lifting and material handling applications, including in confined spaces, production lines, and maintenance tasks.

When selecting a low 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, especially in environments with limited overhead clearance.
