Wire Rope Hoists
Wire rope hoists are a specific type of electrically powered hoist. They use wire ropes as opposed to the usual steel chain used on standard electric hoists. A rope hoist is typically used in areas where heavy duty lifting equipment is needed. Such as heavy foundries, large factories and manufacturing plants.
Why Choose A Wire-Rope Hoist?
An electric wire rope hoist device is more suitable for heavy duty lifting applications. This is due to the fact that the right rope can lift much heavier loads when compared to chain hoists. Also wire ropes will not likely drop the load immediately if overloaded or shock loaded, or the rope fails as there are many wires and strands which make up the wire ropes and it is unlikely that they will all break at once. Leaving some intact to hold the load until safely lowered. With a
chain hoist, if just 1 chain link breaks the lift will fail straight away and the load will fall.
Types of Wire Rope Hoists
Lifting Hoists Direct supply four main types of wire rope hoist systems. Standard headroom monorail hoists, low headroom monorail units, foot/base mounted rope hoist systems and bi-rail crab units. The hoists that we supply come from top manufacturers and boast many benefits when compared to other rope hoist machines.
There is a choice of motors which are either conical or cylindrical, both of which are self braking. The conical motor is asynchronous with 1 or 2 speeds and has a conical shaped rotor and brake, actuated by a helical spring. The brake release happens by the axial displacement of the rotor by powering on.
The cylindrical motor option is a three phase asynchronous type with cylinder shaped rotor and disc brake. Available in single or dual speed. A single polarity motor enables invertor control to be fitted for additional speed control.
Another benefit to our wire rope hoists is that they use a 2 or 3 stage planetary gearbox to reduce the speed of the motor to the required rpm.
These hoists are designed to the highest of standards with top specifications. Unparalleled reliability & endurance, all at the most competitive prices.
Wire Rope Hoist Configurations
The range of wire rope hoists you see here are fairly standard, however should you require something a little more bespoke then please get in touch as special configurations may be available to suit your requirements.
Standard Headroom / Monorail Wire-Rope Hoist
These standard types of electric rope hoist are typically used on single girder overhead crane systems. They come complete with their own incorporated trolley system which sits on the bottom beam/girder flange. Standard headroom hoists are normally utilised where there is no working height restrictions under the beam. This is because the hoist is suspended below the beam and therefore decreases the maximum height of lift of the crane.
Low Headroom Monorail Wire Rope Hoist
These are ideal when space is at a premium. Using a twin drive live axle designed trolley with planetary geared motors and gearboxes fitted directly onto the driveshaft of the wheels, thus no need for external gearing.
Foot or Base Mounted Wire-Rope Hoist
This type of hoist can be fixed directly to a gantry type framework which renders it a static hoist. These foot mounted hoists are ideal for areas where hoist travel is not required, and will be used in situ for applications such as repair work. They can be suspended or supported hoists.
Crab Unit / Bi-rail Wire Rope Hoist systems
Crab units are for use on a double girder crane and are ideal for extra heavy duty lifting operations with higher safe working loads available. A crab unit spans the 2 girders and runs along the top edge. The hoist sits on the crab trolley and the rope with hook will descend between the two girders to attach to the load. This type of hoisting system enables the maximum possible height of lift under the beam, however, because the unit sits on top of the beam, more height will be required above the cranes beam / girder, up into the roof space.
