We offer several designs of lightweight portable davit lifting arms, including lean over type davits and vertical split pole type davits. The split pole davits are suited to applications where there is an obstruction which must be worked around, because the unit is relatively compact, it offers an excellent solution for a confined space or restricted access lifitng environments.
To help comply with the manual handling regulations our davit arms are made in three sections, this ensures that the davits are easily transportable when the davit is to be used in more than one location. They are supplied CE marked and come with a certificate of conformity. The design of the davits means that they are very portable. Many of our customers purchase several davit sockets, and permanently install these wherever they require the davit. One davit arm can then be purchased and easily transported between jobs - reducing the overall cost.
This type of light weight davit lifting arm is mainly manufactured from galvanized mild steel though can also be manufactured from aluminum or stainless steel if required. The galvanized steel arms are suitable for use in marine and offshore environments, whether this be for a lifting application in the offshore oil and gas industry, or for use on a boat. The aluminium option offers an even more lightweight solution. The Stainless Steel davit arms can be used in hazardous environments. These davits are often utilised in the petrochemical industry, where they are used in hazardous environments, and also the food industry, where regulations for cleanliness must be observed.
All of our special davit arm jib cranes can be manufactured to our customers specification (height of lift and reach). In order to maintain the integrity of the davit we recommend that for a Safe Working Load (SWL) of 500kg the radius (reach) does not exceed 1800mm; and for 1000kg 1200mm. The height to the lifting eye on the davit arm can be up to 3000mm. These figures are given as a rough guide. If your requirments do not fall within the advised parameters, please submit your required measurments, and we will quote the item or our suggested alternative that may meet your needs. If the reach of the davit arm you require exceeds our recomendations, but a lower safe working load is acceptable, then we could manufacture a bespoke davit arm that meets your requirments.
Our davit jib arms can be designed for the lifting of materials and / or for the lifting of people (manriding application). To view detailed specifications, information and options on our man-riding davits please click here. For general lifting applications the davit arm’s can be supplied up to 1000kg safe working load (SWL). For material lifting applications our Davits can be supplied with a manual hand winch, electric chain hoist, pneumatic hoists or hand chain block to suit your lifting needs and environment.
We can quote for hoists or winches to almost any specification. The more popular chain hoists we offer can be viewed online under their own category of hand chain hoists. If you have a specific requirment for a winch or chain hoist please speak to one of our sales team and we can tailor your quotation to suit - for example we can offer spark resistant and corrosion resistant units, suitable for use in hazardous environments. The products of Selby Engineering and Lifting Safety are first choice for specifiers and engineers worldwide. Our davit sockets are used extensively in the chemical, water treatment and offshore oil and gas industries. We have a wealth of experience in the development of all types of individual davits and sockets for numerous applications.We offer several socket options for our davit arms, please see the drawings below.
Davit Sockets
Bolt-Down Surface Mount Socket
Available in 1000kg and 500kg ratings for use on flat surfaces. Cover plate can be supplied if required. Surface protection hot dip galvanised to BS1461 as standard. Stainless steel 304/316 material can be supplied/manufactured.
Grout-In Socket (with Cover Plate)
This type of socket is fitted when a flush non-trip hazard installation is required. A cover plate is fitted as standard, secured with 3 x 8mm fasteners. Surface protection hot dip galvanised to BS1461 as standard. Stainless Steel 304/316 can be supplied/manufactured.
Wall-Type Sockets
Vertical installation to suit 500kg and 1000kg davits. Hot dip galvanised to BS1461. In our product range we offer back plates and tiebars to accompany the wall-type sockets for use on a brick wall. We also offer these items in stainless steel 304/316.
Inverted Davit Socket
Widely used in steel walkways where a flush installation is required to eliminate trip hazards.
This type of socket can be mounted flush within open mesh flooring section. Manufactured to suit the 500kg and 1000kg davit pins. Surface finish hot dip galvanised to BS1461 . This type of socket can be supplied in 304/316 stainless steel.
The drawings below give an indication of the style and size of davit's available, though as all our davit arm cranes are made to order the specification can be changed to meet your individual specification.

Davit Cranes With Spark Resistant Features / Explosion proof.
SELS can include any anti-sparking features our customers specify on davit lifting arms we manufacture that are intended to be used in potentially explosive areas / atmospheres (Zone 1 & 2 etc...) – These features will enhance the davit’s anti-sparking properties and therefore make the crane more suitable for use in such potentially explosive environments.
SELS will not to take the responsibility of supplying our Davit cranes described as 'spark proof' or ‘Explosion Proof’ as this is ‘too broad’ a term. We believe that total compliance is probably impossible because of the mechanical operation and movement of a davit crane; i.e. we cannot offer a 100% guarantee that no part of the assembly is capable of generating a spark capable of igniting a flame. We supply / manufacture our cranes with anti sparking features according to the requirements and specification of our customers and therefore we ask our customers to provide a detailed specification and not just ask for sparkproof or explosion proof . Our cranes have been successfully supplied to customers in the offshore Oil and Gas industry in the UK on this basis.
