Column jack with planning and assembly
A customer contacted us about moving his laundry carts from one floor to the next. Our technician went to the customer to get an idea of the situation on site. Some solutions and options for lifting the cars to the upper floor were discussed. In the end we decided together Column lifter with grid shaft to use.
A hydraulic column jack 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 housed in the mast, which is located on one side of the platform. The shaft framework is free-standing. However, in this project, the jack's mast had to be attached to load-bearing supports or a supporting wall. Depending on the requirements, the grid shaft can be built so stable that it can also take the load of the column and no load-bearing wall is required.
Planning from 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 system drawing and a shaft plan. This was checked and approved by the customer's architect and structural engineer. Only after this release will the order be put into production.
Delivery times for such projects always depend on the current workload. On average we can assemble in around 15 working weeks.
In this project phase, we also coordinate with our civil engineer as to whether the system can be accepted in this way. If there are any additional requests, we can respond before costs are incurred.
Column lifter - delivered, assembled and put into operation
Delivery and start of assembly
Depending on the project and local conditions, our column jacks are delivered pre-assembled. It is also very important to check in advance whether you can enter the building. The doors and the turning radii in the hall must also be sufficiently large.
The column will later be attached to these supports and all forces will be transferred to the ground.
The floor, especially in the area of the column, must have sufficient strength. This must be checked by the customer by the structural engineer.
Introduction into the shaft
The column jack was delivered pre-assembled so that the assembly time on site could be kept as short as possible.
Column lift lower stop
With this freight elevator project you can immediately see that no pit has been created here. The column lifter became direct on the hall floor assembled. Loading takes place via a ramp supplied by us.
A double-leaf mesh door with forced contacts was installed to provide access to the lift. The door only opens if the platform is in this position.
The column lifter operates in automatic mode, which means that you press a 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 grid shaft was also installed on four sides of the upper stop. This serves as fall protection. The shaft has a height of 2300mm - however, according to the standard, 2000mm would also be sufficient.
A half-height railing is only permitted if the level difference is less than 3000mm. Depending on the authority/inspector, other requirements can also be specified here. We therefore always clarify the admissibility in the planning phase.
On the same side as in the lower stop there would also be a 2-wing. Door with a forced contact (red in the picture) installed. This door only opens when the platform is on the upper floor. The system only moves if both gates are properly closed.
Thanks to our system, the customer hardly had to make any changes to the building and can now easily operate the upper floor with his cars.
