Column lifters with planning and installation
A customer contacted us that he wanted to transport his laundry trolleys from one floor to the next. Our technician went to the customer to get an idea of the situation on site. Some solutions and possibilities to lift the wagons to the upper floor were discussed. In the end, we decided together to use a column lifter with a lattice shaft .
A hydraulic column lifter has the great advantage that there is no need to create a pit in the ground on the lower floor. The lifting technology is completely accommodated in the mast, which is located on one side of the platform. The shaft scaffolding is free-standing. However, in this project, the mast of the lifter had to be attached to load-bearing supports or a meeting wall. Depending on the requirements, the lattice shaft can be built so stable that it can also absorb the load of the column and no load-bearing wall is required.
Planning by the load lifter
After the lifting solution has been determined, the customer has received an offer from us. After this was ordered, our designers created a plant drawing and a shaft plan. This was tested and approved by the customer’s architect and structural engineer. Only after this release is the order placed in production.
Delivery times of such projects always depend on the current capacity utilization. On average, we can assemble in about 15 working weeks.
In this project phase, we also coordinate with our civil engineer whether the system can be approved in this way. Should any additional requests be added, we can react before costs have arisen.
Column lifter - supplied, assembled and put into operation
Delivery and start of assembly
Depending on the project and local conditions, our column lifters are delivered pre-assembled. For this purpose, it is also very important to check in advance whether you can get into the building. The doors and the turning radii in the hall must also be sufficiently large.
The column is later attached to these beams and all forces are diverted to the ground.
The floor, especially in the area of the column, must have sufficient strength. This must be checked by the structural engineer on the customer’s side.
Insertion into the shaft
The column lifter was delivered pre-assembled so that the assembly time on site could be kept as short as possible.
Column lifter lower stop
With this freight elevator project, you can immediately see that no pit has been created here. The column lifter was mounted directly on the hall floor . Loading takes place via a ramp supplied by us.
As access to the lifter, a double-leaf lattice door with forced contacts was installed. The door only opens if the platform is also in this position.
The column lifter moves in automatic mode, i.e. press the button once and the platform moves to the upper floor. During this time, the employee can walk up the stairs to the next floor or the second employee can take over at the top.
The shaft was pulled up to the ceiling and the entire lifting area was ideally secured.
Column lifter upper stop
A lattice shaft was also installed on 4 sides of the upper stop. This serves as fall protection. The shaft has a height of 2300mm – according to the standard, however, 2000mm would also be sufficient.
A half-height railing is only allowed if the difference in level is less than 3000mm. Depending on the authority / auditor, however, other requirements can also be determined here. Therefore, we always clarify the admissibility already in the planning phase.
On the same side as in the lower stop would also be a 2-flg. Door with a forced contact (red in the picture) installed. This door only opens when the platform is on the upper floor. The system also only proceeds if both gates are properly closed.
Thanks to our system, the customer hardly had to make any changes to the building and can now ideally serve the upper floor with his cars.
