As the guideway and buffer in hydraulic elevator and towable boom lifts are supported in the air of the bottom pit, when the safety clamp and buffer are put into action, the air will be able to accept their vertical force. As for the space that people can get into under the bottom pit, the bottom of the hole pit should be at least 50,000 N/m in addition to the 2 loads designed. The WEIGHT (balance weight) buffer design device should also be extended to consolidate the ground on solid pile piers, or the downlink overspeed protection device should be installed on the weight (or balance weight).
The relevant equipment and installation in the pit shall meet the following requirements:
1) The installation should be stopped in the pit, and the door should be opened to enter the pit for easy access to the air in the pit.
2) Fixed lighting installation and its switch shall be provided, as well as independent power sockets.
3) When the pit depth is not less than 1.2m, a fixed ladder that does not protrude into the operation space of the simple elevator should also be set. It is suggested that the bottom pit depth should be adhered to at most 1 to ensure sufficient safe spacing and safe space (except the simple hydraulic elevator directly acting).
Hydraulic lift bottom pit requirements
Basic requirements of the bottom pit: The bottom pit is located under the ground of the bottom station and should be kept neat. Except for the base installed by the buffer and guide and the drainage installation, the bottom of the bottom pit should be lubricated and smooth without water seepage. Measures should be taken in the drainage installation to avoid water returning to the bottom pit.
