There are many differences in the gantry hoist and the scaffold hoist. However, there are also many similarities.
The gears in the gearmotor are submerged in oil and made of a helical-toothing that will allow the hoist to work at a quieter level. The use of oil as lubricant offers higher protection and lengthens the life of the machine.
The steel rope cable drum is installed transverse to the mounting bracket. This improves smooth winding and eliminates dangerous accumulation of the rope on one side only, caused by flexing of the support structures.
To warrant higher machine reliability and longer life, the drum is built with a special patented device, which when the metal rope is completely unwound, keeps two turns always wound. This prevents straining the rope attachment point on the drum.
This hoist is used particularly for heavy duty tasks, so it can be used for heavier items. Due to the scaffold beam at the top of the gantry, it can extend much further off the building. Thus it can carry much larger items than a scaffold hoist.
They are mounted onto the scaffold with ballast boxed weighing it down in order to counterweight the hoist.
The beam at the top of the gantry, is specifically designed for each hoist, as we supply a 300kg and a 500kg beam. We also have a 500kg beam that can be fitted onto the scaffold, eliminating the need for the gantry all together.
We supply an ET 300 N and a G500.
The ET 300 N is a single-phase 110V electric motor (230v optional), with an average full load lifting speed of 19m/min. And has a maximum capacity of 300kg. Meaning it is bigger than any of our scaffold hoists, where the maximum load is 200kg.
The G500 also has a single-phase 110v electric motor (optional 230v). With an average lifting speed of 17m/minute and a maximum capacity of 500kg. Though it is slower to climb the building, it has a much higher maximum load, meaning it is useful for very large sites.
The scaffold hoist is the smaller hoist out of the two, as it can be easily attached to scaffolding. The larger of these hoists come with a maximum capacity of 200kg and a working height of 30m.
These machines are mounted to the scaffold via a 1.8m beam using provided bolts and clips. Ensuring the hoist is easy to set up and quick to use.
All our scaffold hoists have a pendant station complete with cable 1.5m in length (whether moulded or with plug). In order to be released, the stop button has a twist motion, so it cannot just come out without someone twisting and pulling it. The frame that the hoist sits on can also move from side to side and has a work position lever, so it will stop (and lock) in the position that is needed. This lever prevents dangerous rotation of the load that occurs during lifting or lowering operations. This device eliminates the risk of any uncontrolled movement of the load, reducing the risks for the operator and damage to structures.
Our range of scaffold hoists consist of the ES 150 N, ET 200 N, and TR 225 N.
ES 150 N is the smallest scaffold hoist we supply, being able to carry up to 150kg. It is an ideal machine for those small sites, and if not a lot of material needs lifting and when a frame extension isn’t requited. It is also the lightest and the cheapest of all the available machines.
The ET 200 N, due to its smaller size, is also ideal for operations that do not require an extendible bracket. The maximum capacity for this machine is 200 kg and it has a maximum working height of 30m.
The TR 225 N is a hoist that has a 200kg maximum working load, however it does come with an extendible arm. The arm can be extended up to 1120mm. This hoist has a low noise level allowing work to go on without causing noise that could be harmful to the operator’s health or bothersome to others.
