Electric Chain Hoist considerations And custom solutions we offer as standard…
When assessing an electric hoist application it is advisable to consider the following:
• Environment
Is the hoist to be used or stored outside If the answer is yes, then consideration must be given to the level of protection provided. i.e.: a cover to park
the hoist under when not in use or a higher level of enclosure specification. Can the hoist be easily removed for storage when not in use
• Power Supply
Is there an adequate power supply available adjacent to the hoist location What is the distance between the hoist and the supply If there is then is
the supply suitable, i.e.: 400v 3Ph 50hz, 110v 1ph 50hz. Please specify others if different.

In each case it is recommended that the supply cables and equipment are checked to ensure compatibility and that the installation conforms to the current UK
and European standards.
• Atmosphere (ATEX)
There are applications when equipment is required to work in hazardous areas such as petro chemical and pharmaceutical plants. The user then has a
duty to identify if there are gases and the classification or zoning of the area must be under taken by the user and suitable equipment obtained.
To learn more about hoists in explosive environments please contact Lift Turn Move’s sales office and ask for the ATEX product catalogue. Tel: 0151 649 0467
After considering the above, the following custom hoist features from LTM maybe of interest to you
Travel Limit switches;
• Proximity - we have developed limits suitable for use in the Nuclear Industry.
• Mid travel limits - to stop travel in one movement direction for position. (NOTE - requires custom control panel which is available from LTM).
• Two emergency limits in addition to working units
• Mechanical stops (to fit on chain to stop travel movement - a simple but efficient solution)
Positional Encoders; Two types are available.
• Incremental
• Absolute
NOTE - control systems are needed for feedback from the encoders (which LTM can provide).
Upper or Lower Suspension;
• Upper suspension can be an eye, swivel hook or custom plate.
• Locking hooks
Handles;
• We can add carrying handles to the chain hoist body.
Load Cells ; Two options available
Installed on hoists in the eye or hook suspension (internal). Load cells can be fitted to eye and hook suspension to detect pre-set under and overloads or show
an actual load on a hoist, or external units supplied as load cells within shackles.
NOTE - Separate monitoring system and cabling will also be required and can be provided by LTM.
Control;
• Portable or wall mounted control units to operate multiple chain hoist systems.
• Radio control (wireless) – for single or multiple hoist systems
Hoists working outside or in aggressive atmosphere;
• The standard IP rating for a GIS hoist is to IP55, we can now upgrade the hoist to IP65 Class (Ingress Protection), totally protected against dust ingress
and protected against low pressure water jets from any direction (i.e. Rain).
To further protect your hoists, there are a number of additional protection (extra cost) features which can be fitted including:
• Galvanised Chain – The biggest threat to protecting outdoor hoists is the chain. Galvanised chain is the best protection against the elements and we
will be over greasing the chain to protect it further. (NOTE we fit black chain as standard in Entertainment applications, Galvanised in Industrial).
• Drainage Holes – This allows any water running down the chain into the pocket wheel to pass straight through the body rather than collecting inside
and causing rust/chain damage.
• Release & Over Pressure Valves – This valve acts as a barrier preventing any moisture in the air being drawn into the body. When a hoist is hot from
running or from being out in the sun all day and then cools down, the pressure difference built up inside the hoist will naturally draw in air. The valve
equalises this pressure, whilst preventing any moisture entering similar to Gore-Tex in outdoor clothing.
• Dipped Transformer – As an added precaution, we can tropical dip the transformers, this is a waxy protection that coats the sensitive transformer completely.
• Weather Covers – The weather cover will protect the hoist from the worst of the elements.
Further GIS Options;
• Stainless steel components
• Food and pharmaceutical grade hoists- stainless steel components plus special coatings in place of paint
• ATEX hoists
• Duo hoists
• Synchron hoists
